At the risk of being flamed, I'm trying to work out if I should go ahead with this deal or not.

I am aware of VoltX products and they seem reasonable quality. I can't really find too much bad about them online.

The price seems incredibly cheap (which makes me a little nervous). I spoke to a consultant (overseas call centre) and they discounted it on the spot a further $500 without asking so $5420 after all the rebates.

Anyone else had any experience with these guys before I pull the pin?

I already have a decent solar system and I export 30kw a day roughly, and this comes with an inverter which they (I assume) divert my solar into these batteries.

Too good to be true?

      I dont think just upper class you can get an 10kw system for 2k to 3k here in Perth using Neovolt and if you dont have the cash maybe apply for the loan scheme? Sometimes I feel people dont wanna do anytthing and get the 2.3b as Centrelink payments hahaha

        When I say upper class, I mean home owners, that in itself puts you in the "upper class" in Australia's F'd up economy.

        Renters can't put this sort of thing in.

        For the record, I own multiple homes so I'm not saying this as a "woe I me, why is everyone else getting handouts"… It was more in that Labor voters love to say that libs just give the upper class handouts, then Labor turns around and does the same thing.

        I know I'll get downvoted for pointing this out on ozbargain, it's not exactly the demographic to point out the hypocrisy, but it doesn't make it any less true.

          Ahhh ok ok, well we are in a one party country haha doesnt matter which one is in power is the same BS quite hard. but fair point I hope one day I can be on upper class with many houses like you hahaha

        • supersabroso on 15/08/2025 - 13:52

          By that logic, 2/3 of Australia are in the upper class, this is definitely not true. The upper class is generally defined as people in the top 10% ie. Households with a net wealth of $3.5M+ & a total gross income of $430k/year+.

          This deal is more geared towards the everyday Aussie family, the median household with $158k/year of income & $1.245M of net wealth.

    • supersabroso on 21/08/2025 - 15:54

      This is for the middle class, your typical median family on $140k/year with $1.2M of net wealth. The upper class are busy buying Telsa Powerwalls for 4x the cost lol. It's a worthwhile spend of tax dollars because $2.3B will subsidise about 8MWh of home batteries that should last the next 20 years or more. At the current rate we are being charged, it's worth $2.6M/cycle in savings. Assuming 200 cycles a year, that's $520M/year in savings or $10.4B of savings over 20 years in today's dollars.

  • USER DC on 15/07/2025 - 21:28

    Is it actually good ??

    • ilubbargains on 15/07/2025 - 23:45

      Been told Neovolt batteries are at one end of the spectrum (low), while Tesla batteries are at the other end. I'd need to read more to figure out whether this is simply marketing spin to try and milk more money out of me

      • supersabroso on 15/08/2025 - 14:04

        It's likely that this is true. However, based on the warranties, this battery is superior as they are guaranteed to retain 80% of their original capacity once the 10 year warranty runs out. However, a Tesla powerwall is only guaranteed to retain 70% of it's capacity after the same 10 year warranty. In the unlikely event that in 10 years' time, the battery is dead, you'll be glad that you managed to pay off this battery in 4 years instead of 25 years like 2.5x Tesla Powerwalls.

    • ohgee on 16/07/2025 - 00:00

      Good? No. While some will try to convince themselves that this is greater bang for buck the reality is that this offering will allow greedy energy retailers to continue to gouge customers.
      In short, buyers of this type of offering won't have the means to charge it to capacity daily, nor can the likes of OVO 3 hour "free* grid charging get it done.
      The primary shortfall is the inverter, both charging and discharge capacity. Any demand greater than 5kwh will see a draw from the grid and this is what retailers are banking on. If they can't steel your electricity via a nonsensical vpp agreement they'll try to in this form.
      If you don't have the need to compensate for frequent grid outages ignore this battery nonsense and play the game in its simplest form.

      • furyou on 17/07/2025 - 00:12

        what if u have a battery ready inverter? Doesn't that mean it'd cost even less, 1 less box, and you're not limited to their 5kw?

        • ohgee on 17/07/2025 - 08:09

          If you have a hybrid inverter a battery will be DC coupled and charged directly from solar panels. The charge rate will be limited to the battery specs and available PV input. The discharge rate (and grid charging) will be limited to the battery specs and/or the size of the inverter, whichever is lowest.
          Cost would be variable depending on the actual system, likely more expensive for a much more capable 10kwh hybrid inverter, ~20kwh battery setup. It really depends on the specific products.

    Been using the Neovolt since October 2024. Works fine for an AC-coupled battery. Multiple batteries are side by side, they are not stackable on top of each other. It measures the inflow from the grid and discharges the same amount so that your smart meter detects a net zero import. So a smart meter is required if you are one of the last few holding out to avoid time of use or demand tariffs. If you have a load exceeding 5kW, the battery inverter will output 5kW and the difference will be imported from the grid.

    If you have solar panels, the solar will be used to power your home loads first and any excess which would otherwise be sent back to the grid will be used to charge the battery.

    Neovolt is compatible with Amber now.

    I have a 2x 5kW system with 20kWh of batteries. I couldn't live without the 10kW total battery inverter, but do wish I had 30 or 40kWh of battery capacity, but I can't add it due to the lack of wall space. In this respect, I do wish that I went with the Sigenergy Sigenstore instead because of stackability.

    • BusMan247 on 16/07/2025 - 01:32

      Thanks for the post. Tbh ive read the whole thread. Good read. Im about to install a 20kw SAJ battery. Maybe i should go with this neovolt? Similar price for 30kwh.

    • chrisharry53 on 16/07/2025 - 10:01

      I have 6.5kw Fronius with 6kw of panels. 2 storey ducted a/c. Wife hates the cold. Used 36 and exported 2 yesterday, solar generated 7. We had little sunshine. Prior day was nice. Used 21.5, feed in 20 and 26.5 generated.

      So, is my system technically suited to a 30kw battery system?

      Note that I live in Charlestown, NSW, near Newcastle.

    • aka nioh on 20/07/2025 - 10:49

      Hey sleepy cat, do you find the battery is quick to respond to loads? Eg if I turned on the kettle/oven or would the battery cover the 2kw + load instantly? I read a review on solar quote that a users battery respond slowly causing some grid usage. Thanks

  • V2L on 16/07/2025 - 07:47

    blackout protection would be an important feature for me, so neovolt doesn't have this facility? I'm leaning towards the sig as it's more future proof, stackable, can add on DC charger for EVs, supports triple phase but almost twice as expensive

    • Buyingcrap on 16/07/2025 - 08:21

      I have 2 power circuits and a light circuit backed up with my Neovolt, so yeah it is possible. 3 phase is also an option but I have no idea about DC charging, I suspect not.

    • Dogsrule on 16/07/2025 - 11:40

      supports triple phase

      Just so you're aware, in a 3 phase scenario the Neovolt will export on the phase its connected on to net out imports on the phases it isn't connected to.

  • djsweet on 16/07/2025 - 09:59

    Worth it if you have 3-phase?
    I think my AC is on a separate phase which will be the biggest single power consumer, especially at night. So.. hm. Would I need to get two of these systems to serve 2/3 of my phases? Would that even work? 60kwh is a lot of battery, and it would probably go underutilised. But for this price :shrugs:

    • Dogsrule on 16/07/2025 - 11:49

      The installer will connect this power meter across the 3 phases which makes the battery aware of imports on the 2 phases it isn't connected to. The battery will then export on its connected phase to net out the imports on the other 2 phases. You only need one of these battery systems connected to one phase to achieve this, no need to buy 2.

      Definitely worth it.

  • Tyken on 16/07/2025 - 10:01

    Apparently these batteries are repackaged Alpha batteries in blue paint. Alpha was imported by a company that disappeared from Australia only to reappear under a different brand ‘neovolt’.

    If you read forums about the Alpha batteries it will give you some idea of how long these lasts and how people’s claims on warranties were.

    Hi everyone - David here from the VoltX Energy Team.

    Firstly, a big thanks to everyone who’s shown interest about the $5,920 deal for a 30kWh VoltX Neovolt battery system with a 5kW inverter, fully installed across NSW, SA, and QLD.

    I wanted to jump in personally and answer a bunch of the recurring questions and concerns I’ve seen throughout this thread.

    I'll do my best to monitor comments under mine and respond to follow-up comments as best I can.

    Why is it so cheap? Is it legit?

    This is the big one. And yes, totally fair to question it.
    Earlier this year, VoltX secured what’s believed to be Australia’s largest bulk purchase of home batteries. That scale let us negotiate steep discounts and we’ve passed that on to customers. It’s not “too good to be true”, its just well-timed volume buying.
    VoltX Energy is New Energy Tech approved seller (previously known as CEC approved Retailer). The system is Clean Energy Council approved, eligible for full rebates, and installed by licensed local sparkies. You’re not dealing with grey imports or unvetted hardware.
    We’ve been operating in the energy and technology space for over 13 years. VoltX Energy was established as a dedicated entity 3 years ago, formed through a strategic partnership and the collaboration of several experienced professionals from across the industry.

    What’s included in the $5,920 price?

    • A fully integrated all-in-one inverter and battery system
    • 30kWh (3 x 10kWh) Neovolt LFP batteries
    • 5kW AC-coupled inverter (single phase)
    • Standard metro installation (within 5m of switchboard, ground-mounted)
    • All electrical compliance, safety switchboard work, & CEC documentation
    • Wi-Fi-connected module + app for monitoring battery charge/discharge
    • VPP compatible with Amber and GloBird

    Pricing

    The Federal rebate is already applied in the $5,920 price (you don’t pay full price and wait for any refunds, we handle it).
    Backup functionality is available for $600, and this includes the components and re-wiring required for 2 circuits. Typically, this would be one power circuit (that includes a fridge) and a light circuit.
    If you’re in regional/rural zones, there may be additional site and travel costs.

    Are the batteries stackable?

    Yes, we now offer new mounting brackets that support:
    * Depth-stacking: installed front-to-back, extending outward from the wall.
    * Vertical stacking: stacked one above the other.
    This helps reduce wall width requirements and is great for tight garages or side installs. The final setup depends on space and safety clearances. Our team will recommend the best layout for your home.

    Is a 5kW inverter enough?

    It depends on your household’s usage.
    The battery inverter provides up to 5kW continuous output. If your total load exceeds that (e.g. ducted AC + oven + EV charger), the battery covers up to 5kW, and any extra comes from the grid.
    You don’t lose power, you just draw the excess from the grid. Think of the battery as shaving your peak or covering your night-time base load.
    * It’s possible to run two inverters with a parallel kit
    * Inverters can be added later (they’re not rebate-linked)
    * Battery rebates apply once per household
    Our team can help assess your setup and recommend the right configuration.

    Is this good for EV charging?

    Yes, the battery will help offset the load. If your EV charger is 7kW+, the system will feed part of it and the rest will come from the grid.

    Can I use this with a Amber, Globird, or other retailer time-of-use plans?

    Yes, and this is encouraged. We are:
    * Compatible with Amber and GloBird VPPs
    * Supports automated charging during cheap windows (e.g. 11am–2pm free)
    * CT clamps enable accurate net-zero import tracking
    We’re also working with additional energy retailers to expand compatibility with more Virtual Power Plant (VPP) programs across Australia.

    What’s the warranty?

    • 10-year product warranty.
    • 10-year workmanship warranty.
    • Unlimited throughput - no cap on charge/discharge cycles.
      It also includes an unlimited throughput warranty, meaning there’s no cap on the number of charge and discharge cycles over the 10 years. This level of coverage is rare, and as of now, only VoltX Neovolt and Tesla offer this in the Australian market.
      For a deeper dive into why throughput matters more than just cycle count, Solar Choice has a great explainer here: Article

    Can I see real install photos or customer feedback?

    Yes for sure! Please see:
    Case Studies
    Product Review
    7News Story
    Note: updated stacking bracket photos will be added soon.

    Final thoughts from me…

    We understand this is a high-value investment in a space full of noise and hype. Our team has focused on delivering a clear, compliant, and genuinely affordable option.
    It’s the same approach we’ve taken across every product category we’ve brought to Australia: reliable products, disruptive pricing, no compromises.
    If you’ve still got doubts, that’s okay ask away and I’ll do my best to respond here.

    A heads up - since the federal battery rebates launched on July 1st, we’ve seen a massive surge in enquiries.
    Our team has been ramping up operations to keep up, and while response times have slowed slightly, we expect to be back to normal response times within 1–2 weeks.
    Also, like many in the industry, we're seeing some supply chain pressure, this is affecting retailers across the board. That said, we're actively managing stock and logistics to fulfil orders with minimal delays. We’re actively reaching out to customers whose orders may be affected, and doing our best to keep everyone informed ahead of time.

    P.S. To say thanks for all the insights and discussion, I’ll be sending a free VoltX 5,000mAh Power Bank to 5 top contributors in this overall post.
    I will announce them here on Thursday, 24th July at 3PM (AEST).

    AMA.

              @VoltX Energy: Hi David,

              I want to purchase the 50kw package. Do the batteries stack 2 vertically and 3 on ground level? Do these brackets cost extra or are included in the price?

              • AssociatedVoltX Energy @ VoltX Energy on 16/07/2025 - 17:42

                @Tyken: @Tyken

                As long as the layout is compliant with safety regulations and manufacturer guidelines, that structure is absolutely possible.

                That said, the final layout is:
                - Assessed by our technical team
                - Reviewed by our installation planners
                - And confirmed again on-site at the time of install

                The mounting brackets, whether vertical or depth-stacked, are included in the package at no extra charge.

                As for the 50kWh setup, it's actually one of the most cost-effective configurations available. Let me expand on why, since I didn't touch on this earlier:
                - The federal battery rebate only applies once per household, so by going larger up front, you're maximising your one-time rebate savings.
                - You reduce grid reliance during longer overcast periods.
                - Optimise time-of-use plans (e.g. charge during off-peak, use during peak).
                - It allows you to sell more surplus power into VPPs if you're enrolled in one.
                - Prepare for future needs such as EV charging. Or liver more comfortably.

                Cheers,

                    @31mop: Hi @31mop

                    Great questions and apologies for not making this clear earlier.

                    There are actually three different mounting options available, and I should have explained this more thoroughly:
                    - Wall mounting. And yes, this does have a cost of $250 per mount.
                    - Vertical stacking (floor-based).
                    - Depth/front-to-back stacking (floor-based).

                    The vertical and depth-stacked options are placed on the ground, and we currently do not charge for the updated brackets used for these configurations.

                    However, wall mounting is a separate option. Since the batteries are heavy and need to be anchored securely into the wall, this setup requires specialist hardware and labour, which is where the $250 per unit charge comes in.

                    Cheers,

        Hi @Tyken

        I had a look into your quote and I can see our sales team have already applied some aggressive discounts. Just to keep things transparent, here's a quick breakdown of how that pricing was structured:
        - Our Single phase VoltX Neovolt 50kWh battery with 5kW inverter is normally $12,200. We have promotion bringing this down to $9200.
        - On top of that, your quote includes stackable discounts that apply under certain conditions, e.g. specific service regions or frontline eligibility.

        I've done the math and honestly, I can't beat that total price directly.

        However, I can offer a different angle that delivers better overall value based on what you've been quoted.

        For the next 2 days only, I'll offer all OzBargain users 2 options:

        OFFER 1

        Single-phase VoltX Neovolt 50kWh system (5 batteries, a 5kW inverter and standard installation in metro areas)
        PLUS backup functionality (worth $600, and for 2 circuits).
        $6,700 INCLUDING backup functionality.

        OFFER 2

        Single-phase VoltX Neovolt 50kWh system (5 batteries, a 5kW inverter and standard installation in metro areas)
        $6,300

        Please note:

        This pricing is valid for 2 days only, until 5PM AEST, 18th July 2025.

        No removal of features or custom downgrades, the offers are fixed at this price. Additional variations can be added as needed.

        This offer carries some risk on our end depending on install locations and logistics, but I'm happy to roll the dice and honour it for these 2 days.

        To claim this offer:

        When you speak with the team, you must say:

        David's Discount from OzBargain

        It has to be worded exactly like that, same order, same phrasing.
        If you say "OzBargain discount David" instead, the staff are strictly instructed to bump up your price, for absolutely no reason at all :D

        (Okay, not really… but keeping it fun.)

          I'm also interested in the same quote - 50Kwh, smart metre for triple phase, 10kwh inverter (no solar currently but allow in future, but maximise grid charging in off-peak times.

          Also a few other questions:

          1) If I get the 10kwh 3 phase inverter does that mean that I can charge 30kwh of the battery in 3 hours and it would take 4 hours to discharge 40kwh to the grid?

          2) Can you set it to automatically stop exports to the grid if negative FIT on amber?

          3) Currently have no solar - if solar is added later can battery be charged during a blackout?

          4) Is it ok to install a battery outside in a coastal location?

          5) What depth is required to fit a single battery?

          Thanks, pending these few things being sorted I'm ready to pull the trigger :)

            @thestig: @thestig

            I'll answer this based on the assumption that you are considering 2 x single-phase 5kW inverters (with a parallel kit) along with our single-phase batteries, set up for a 3-phase home.

            If I misunderstood this, please let me know and I will adjust my answers.

            We have many customer installs where they didn't add solar, who have had great success in getting a return without solar.

            1) Yes, that's correct. You can charge at up to 10kW, meaning 30kWh would take 3 hours. And you could discharge 40kWh in 4 hours. Please note, to be very precise, there are minor adjustments to be made to this due to inverter efficiency, and other factors.

            2) The VoltX Neovolt battery is Amber approved. These details are controlled by Amber's SmartShift.

            3) Yes you can. To enable battery charging during a blackout (via solar), you'll need:
            - An upgraded hybrid inverter (we have these available, please request a quote)
            - Backup protection added on

            4) Yes, totally fine.

            5) The batteries front panel to the wall needs 200mm. Clearance required from the front panel out is 300mm.

            Cheers,
            David

            • thestig on 17/07/2025 - 12:44

              @VoltX Energy: Thanks for your reply.

              I'm considering your suggestion of either an additional 5kW single-phase inverter ($1500 extra) or awaiting a price on the hybrid option (10kW I assume?) to allow solar charging in a blackout.
              1) Does the balanced thing not matter with 2 inverters and 50kwh batteries on a 3 phase house?

              The area I'm hoping to install them is a 580mm gap between my garage and a fence, so it sounds like this should be ok.
              2) If at the site visit they determine it's not suitable, is the deposit refundable?

              I was told that I need solar panels installed to qualify for the battery rebate.
              3) Is that correct?

              • AssociatedVoltX Energy @ VoltX Energy on 17/07/2025 - 14:08

                @thestig: @thestig

                Hybrid is still 5kW.

                1) Yes that's correct, if you have a 3-phase setup, we can configure the system across multiple phases in a way that doesn't require perfectly balanced battery distribution.
                For example, one inverter can be paired with one or two batteries on Phase A, and the other inverter with the remaining batteries on Phases B and C.

                The space may be suitable, but we do have to follow several regulatory criteria around spacing, clearance, and access.
                The best next step is to contact our team, who will ask for a few basic details (photos, measurements, layout) and help determine whether the space meets installation requirements.

                2) Yes, if for any reason, the site is deemed not suitable, your deposit is refundable.
                And just to be clear we're not in the business of holding on to a few extra dollars of someone's hard-earned cash. We're here to install great products, offer unbeatable value, and leave behind fully satisfied customers :)

                Here is a previous response I did regarding whether you need charging during blackouts:

                A side note, whether you need charging during blackouts really depends on your location:
                - Most metro areas rarely have long outages, so backup-only is usually enough
                - Some regional or outer-suburb areas with frequent blackouts may benefit from adding the hybrid + solar recharging capability

                3) Yes, that is absolutely correct. You need either an existing, or new solar set up to qualify. That should have crossed my mind and I should have mentioned that. Thanks for pointing that out!

                Hope these help!

                  Is a 5kW hybrid inverter (to allow solar charging) and a 5kW normal inverter a worthwhile consideration at all?

                  You mentioned in a comment yesterday that you would see if you could get any discounts across the line on solar panels installed at the same time. Did you have any update on this?

                  @VoltX Energy: Hi. The 5kw inverter with the standard 30kw offer for $5920 will not charge your batteries during a blackout and you need a hybrid inverter? Is the hybrid able to be included for an additional charge? I do have a quote and have asked this question today. No response as yet. To be clear, I have 3 phase power and no idea what AC and DC coupling means. Cheers

                    @chrisharry53: @chrisharry53

                    Thanks for sharing these questions.

                    The standard 5kW inverter included in the $5,920 (30kWh) offer is an AC-coupled inverter, which does not allow solar panels to charge the battery during a blackout. It can discharge the battery to power essential loads (if you add backup functionality which costs $600), but recharging the battery during a blackout requires a hybrid inverter.

                    Yes, a hybrid inverter upgrade is available, and our team can include that in your quote as an optional add-on. It's the right choice if you want to make sure your solar panels keep topping up the battery even when the grid is down.

                    Also, no worries at all about not knowing what AC or DC coupling means… in simple terms:
                    - AC-coupled = solar and battery operate independently, with energy flowing through separate systems. This is the most straightforward set up that integrates with existing solar panels.

                    Hybrid ( or DC-coupled) = solar panels can directly charge the battery, even during a blackout.

                    Since you're on 3-phase, the inverter configuration and backup options will need to be tailored to your setup and our team can walk you through that.

          Hi David,

          Is frontline worker discount stackable on top of these 2 Offers that you have provided?

          Edit: one more question: Does backup functionaliy mean I can go off-grid if I wanted to? I am in Brisbane Metro area(Energex).

            @JayBholeNath: @JayBholeNath
            Unfortunately not, these two offers are already fully discounted, and we've maxed out all available incentives. That means these are fixed prices, and additional discounts (like frontline/partner offers) can't be stacked on top.

            Regarding going off-grid, the answer is no. These are on-grid systems by nature, and backup functionality does not equal full off-grid capability.

            Here's what it does mean:
            - If you've added backup, your system can keep running 2 dedicated circuits (e.g. lights + fridge) during a blackout
            - This happens automatically when the grid goes down, no manual switchovers required
            - However, the battery will not recharge (using solar) during a blackout unless your system includes a hybrid inverter and a properly configured solar array

            A side note, whether you need charging during blackouts really depends on your location:
            - Most metro areas rarely have long outages, so backup-only is usually enough
            - Some regional or outer-suburb areas with frequent blackouts may benefit from adding the hybrid + solar recharging capability

          For me the reasons could be:
          * In the meantime while we are waiting; if safety/quality concerns for Neovolt batteries appear OR
          * better/similar quality battery offers come in the market for competitive price.

            @JayBholeNath: Hi @JayBholeNath

            This question is really important and I'm glad you raised this.

            We’re not in the business of holding on to people’s hard-earned money if they've had a genuine change of plans. Our goal is to deliver great value, not make a few bucks on cancelled orders. We're in the business of delivering great products, backed by quality installation, all at exceptional value. With the goal of leaving behind genuinely satisfied customers.

            The scenarios you shared are completely reasonable and I can confidently commit that a deposit refund would not be refused in those circumstances.

            The only time we may need to retain a deposit is if we've already scheduled your install or our install team has begun preparing or carrying out the job. At that point, costs are being incurred on our side.

            Think of the deposit as simply a signal of commitment. Without it, if we scheduled installs freely and customers dropped out last-minute, it would cause chaos for our planning, staff, and logistics.

            Hope this helps clear things up and I'd be happy to answer any follow ups to this.

            Cheers,

              Thanks David, I signed up for offer 2 yesterday and appreciate your detailed responses. They said installation will be from October onwards.
              Does that mean you don't have enough manpower to do it sooner? As I believe you mentioned company has already bought a large stock.

              Is there a possibility that the installation can get delayed to November/December?

              Also, maybe it's too much in detail but I will ask anyway; while the batteries are in storage in your warehouse, are they already pre-charged enough about 60% because the battery life significantly gets affected if it is stored with low/no charge.

                @JayBholeNath: @JayBholeNath

                Thank you kindly for signing up with us, we truly appreciate your business and trust!!

                Just to be fully transparent, there are two key factors to consider regarding your proposed October installation timing:
                1. Stock availability:
                While we have large volumes of stock on the water and arriving regularly, not all inventory is landed and ready just yet. The federal rebate has triggered a surge in national orders, which in turn is causing some factory delays in production.
                2. Installer availability:
                We factor this in, however this is not a big bottleneck. We currently have dozens of active install teams, with additional standby crews ready to scale up as needed.

                That said, based on our current forecasts and booked pipeline, I genuinely do not believe your install will be delayed into November or December. All signs point to October completion, with your system likely supplied from a 'fresh shipment', rather than sitting in storage for months.

                For context, we haven't historically had to warehouse Neovolt systems long-term. Each batch that arrives roll off directly into installation. Battery age/storage should not be a concern.

                Yes, all batteries are stored at approx 60% state of charge, in line with strict regulatory compliance for lithium battery handling. And importantly, Neovolt batteries use Lithium Iron Phosphate (LFP) chemistry, which holds its charge far better over time than traditional Lithium-ion types.

                If you're curious, I'm more than happy to dive deeper into the LFP vs Lithium-ion comparison. In short, LFP is safer, more stable, and better suited for home storage systems.
                Here's a Nine News segment where I briefly discussed this exact topic: News Segment

                Let me know if you have any concerns or would like more detail, happy to help anytime.

            @Sparky: I was told it's $1500 extra for an additional 5kW inverter and I'm awaiting a price on a hybrid inverter instead (assuming 10kw) to allow solar charging during a blackout. I'm not sure if there's a third option of a single 10kW 3 phase inverter. My understanding is all options require the $550 3 phase smart meter. Some clarity around all these options would be good. I want to make sure I get it right the first time.

              @thestig: I am in the same boat. I called Voltx today and specifically asked for a quote including a 10kW 3-phase inverter. But only received a quote for the 5kW single phase plus 3-phase smart meter ($550).

            Thanks for the suggestion and I totally understand the interest from our 3-phase Ozb crew!

            At this stage, we're not in a position to roll out an OFFER 3 just yet, at least for a few days or weeks.

            We will try our best!

            Cheers,
            David

              @VoltX Energy: For those of us on 3 phase and wanting a 10kw inverter (possibly hybrid if installing panels at same time?) should we hold-off to make sure we get the best possible system from you guys?

                @thestig: Did we get an answer on this?

                • thestig on 20/07/2025 - 08:25

                  @phirippu: Refer to David's update on page 5 of this thread where he mentions running 2 inverters parallel on 2 phases. He has passed on my details to the team and I am waiting on contact (hopefully tomorrow!).

                  Neovolt do make a 3 phase 10kw Hybrid inverter but I'm not sure if VoltX supply it.

                    @thestig: Thanks there’s so many comments here it is hard to keep track!

                      @phirippu: No worries, yeah you really need to subscribe to all comments and go through your email because a lot of useful information is provided in replies to comments through the thread and not just the most recent comments at the end of the thread.

                    @thestig: @thestig
                    Just to confirm, yes, we do supply the Neovolt 10kW 3-phase hybrid inverter, and it's a solid option specially for customers installing both solar and battery at the same time.

                    Upgrading to Hybrid Inverters

                    • Technically, you can upgrade from standard inverters to hybrid, but it's not simple.

                    • Solar inputs need to be rewired and redistributed, often requiring a full reinstall with new string layouts.

                    • Cost-wise, older inverters aren't offset or compensated… so it's generally better to go hybrid from the start if you're adding new solar.

                    3-Phase System Considerations

                    • If you're only adding batteries (with no new solar), the VoltX Neovolt single-phase solution works very well and is usually more cost-effective.

                    • You could absolutely consider the 3-phase solution, which comes at a slightly higher cost…. though still more affordable than most competing options. In most cases, customers go this route to achieve a cleaner system architecture.

                    • That said, in reality, the single-phase setup may still deliver excellent results.

                    • If you're on 3-phase and planning to add both solar and batteries, the 10kW 3-phase hybrid inverter is the better, cleaner, more future-proof option.

                    • A limitation with using multiple single-phase inverters in 3-phase homes:

                      • Battery capacity on one phase can’t assist the other two.
                        e.g. A battery on Phase A won’t support loads on Phase B or C.

                    System Configuration Scenarios

                    Option 1 – Simplified:

                    • Single 5kW inverter + 3-phase smart meter

                    • Lowest cost, but limited to 5kW

                    Option 2 – Dual 5kW (Single-phase) Inverters:

                    • One on Phase A, another across Phases B & C

                    • Allows for solar + hybrid config, but battery capacity is isolated by phase

                    • Set up using a parallel kit, will be available soon with Neovolts software update (however our next install date for new orders is around the same time anyway)

                    Option 3 – 10kW 3-Phase Hybrid Inverter (Recommended):

                    • Best for integrated solar and battery systems when a new solar system is being installed.

                    • Balanced load across all phases

                    • One limitation to consider: The total battery capacity is capped at 28.8kWh for this solution.

                    A few extra considerations for AC-coupled vs Hybrid inverters

                    • 10kW on one phase is not allowed under grid rules.

                    • Therefore you can't install two inverters on a single phase within a 3-phase system (this is NOT a scenario option above, but just sharing it for further clarity)

                    Hope these help!

                    Cheers,

                      @VoltX Energy: Thanks again for all the info David, there's a bit there to consider!

                      I hope you don't mind but I have a few further questions to help me get my head around it all.

                      Option 2: When you say "but battery capacity is isolated by phase".

                      Can you please provide a bit more details about how this would work in practice with the parallel kit?

                      Do I need to work out what is run on each phase? The a/c might be on all 3 (it has a bank of 3 switches in the switchboard) but I'm not sure about the rest.

                      If I have 50.5kWa of batteries and put 30.3kWa on phase A (assuming most things are on here) and 20.2kWa on phase B&C would I have control over which batteries charge or would they all charge evenly? What about when discharging to the grid?

                      The advantage with this option seems to be I can keep my 50.5kWA of batteries like Option 1 but will have faster charge/discharge and can handle higher drain without using the grid but need to get my head around the drawbacks.

                      Option 3: I can see this inverter is the cleanest option, but do you think it's worth sacrificing over 40% of battery capacity for? Can 3x10.1kWa batteries still be used or do you need a smaller one to get it under the 28.8kWa capacity?

                    • foxpro on 21/07/2025 - 10:25

                      @VoltX Energy: Option 3 – 10kW 3-Phase Hybrid Inverter (Recommended) with 28.8kWh batteries looks good.
                      Someone on the WP thread posted that the six 4.8kwh batteries have a usable capacity of 4.6kwh each. Which means that 6 x 4.6=27.6kwh usable lands them under the NSW VPP limit of 28kwh and thus attract the $1500 rebate.

                      • thestig on 21/07/2025 - 10:55

                        @foxpro: Do you know the price for these instead of the larger batteries?

        • Dogsrule on 17/07/2025 - 15:10

          Thanks David, just signed onto this awesome deal! :)

          Are these deals available to WA? Can you organise a partner installer in WA to install?
