    Are these battery systems capable of charging from the grid?

      Hey Kirynflare,

      Yes you do have the functionality to charge batteries from the grid as well based on your needs. However there may be limittions from the electricity provider/distributor. Depending on your energy plan and its restrictions, however yes this is possible and useful if you are on a VPP or want to take advantage of low electricity rates at various times of the day.

        BYD Battery box which works effortlessly with the Fronius Hybrids

        1) Do you mean the ones like Fronius Gen24? Is that $8k approx including the $1k software update to Hybrid mode?

        2) is their a cheaper battery that can be paired with the Fronius Gen24?

        • nicois on 05/05/2025 - 07:15

          The quoted price is not going to include the $1k software upgrade to enable battery support on a gen24. So unless you've paid that already, it will cost $9k.

          I'm also interested in lower capacity for me gen24. Running the numbers, there won't be enough days each year when I'd use the full capacity to justify the cost. Even a very small battery will help smooth out consumption, and avoid my sending back small amounts to the grid during the day only to import stuff when I boil water half an hour later

          The other reason I'm wary of paying for a bigger battery now is that batteries are still way overpriced. Imagine how much EVs would cost if their batteries cost this much! With CATL and others bringing out even better chemistries, prices have to fall a lot in the next couple of years.

          And of course simply the fact you can get a 10kWh battery with inverter for $5k shows BYD HVM are really trying to milk Fronius owners through lack of competition. Sure it's a 400V battery, and the DC-DC stuff is nice, and integrated load management, but still..

          • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 09:11

            @nicois: Hey Freeb124me and Nicois,

            1) No the $8k doesn't include the activation, that's something you do directly with Fronius prior to having the battery installed.

            2) Not much else really. There is LG but not the best reputation and not much available in the market

            You can always look at a smaller battery from 8.3kW (from $6,000) or 11kW (from $7,000). These units are expandable at anytime with additional 2.8kW modules.

            Agreed BVD does charge a premium and there are other options in the market for a AC coupled solution, for customers like yourself who don't need a lot of storage now best to get a smaller unit which can add modules later down the track with minimal wiring and just plug and play.

            Cheers,

              1) What are you charging for the BYD HVS 5.1kw setup after new battery rebate?

              2) Will the alpha ess system also work with Fronius gen24 without activation as the system is a hybrid. If so what’s the cost for 5kw battery system?

              • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 10:58

                @freeb1e4me: Hey @freeb1e4me,

                1) That would be $4,500 after federal rebate plus $1k Activation that you pay directly to Fronius.

                2) Yes will work as it will be independent to the Gen 24 and has its own Hybrid inverter built in. With Alpha Ess the smallest unit we are offering is the 10kW as the smallest unit for $4,999.

            True but the rebate now makes it more affordable. You can wait for battery to get cheaper but it would have to be significantly cheaper to offset the time waiting and savings now

            • nicois on 05/05/2025 - 13:30

              @freeb1e4me: People tend to see a $500-$1k ROI from a 10kWh battery per year, at best. Arguably lower if you have smart home appliances so your HWS and EV get charged from excess sunlight already.

              If I pay $9k for a 13kWh BYD HVM, and in 2 years' time there is a 13kWh battery for $5k, I would be at least $2-3k out of pocket; better for me to wait for reasonable priced batteries, or V2G.

              Sooner or later BYD will have a competitor in the 400VDC space, and the prices will very quickly drop. The battery just needs an industry standard comms setup, no inverter or other complex battery management stuff.

                @nicois: I predict the batteries will just get bigger in size and the cost will just get higher and they won’t sell small battery sizes so at best you pay the same but get a bigger battery if you want to wait it out

      Hey Windows98,

      That inverter wont be a direct plug and play as its not a hybrid, for direct battery integration you would need the Gen 24 Fronius Inverters.

      We can however offer the AC Coupled solution for a battery brand of your choice. Many of the batteries either have a built in hybrid or can be installed with a hybrid inverter. The hybrid controls the power flow and all energy management or charging and discharging.

      If needed and roof space allows we can easily install panels with the new hybrid inverter to increase your total solar system size for self consumption as well as charging.

    • Associatedmattcerium @ Cerium Energy on 04/05/2025 - 22:07

      Hey AndyRoo,

      It sure it mate, and about time thanks to this new federal rebate.

      As per the offer you can add another 10kW modular battery for an additional $2,800 after federal rebates. This is because the battery rebate is based on the total useable battery wattage so the bigger you go the bigger the overall rebate.

      Just depends on the battery location and available space that may add a small cost of cable runs etc and mounting.

        Hey @Joda,

        Just the battery wont be eligible for the Federal rebate unfortunately without any existing or new solar. The rebate states that you need to connect the battery to a new or existing solar system. Same with the Solar Vic Loan need to have an existing or new system connected to the battery.

        If you have an existing system then this is easily do able if not then depending on how bad the shading is and if the trees could be trimmed this may be an option.

      Hey Frozen,

      All comes down to how much power you are using at night or during low light conditions. If you can utilise the battery efficiently then yep can be worth it.

      Assuming the trees cant be trimmed or cut down? Also if its just winter that the shade is in still got a good chunk of the year with good production.

    • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 09:30

      Hey @techgeek69,

      The good news is that the Federal rebate is available to every one just like the STC rebate for Solar. There is no customer eligibility. So you would still get the federal rebate.

      Here is what you miss out on:

      Solar Vic Solar Panels Rebate: $1,400

      That's it! Not too bad overall.

      The other incentives you would miss out on are the interest free loan options, bare in mind these are LOANS so they need to be paid back so not a rebate as such:

      Solar Vic Solar Panels Loan: $1,400
      Solar Vic Battery Loan: $8.800

        Thanks Matt

        My current inverter is a Growatt MIN 5kW 1 Phase 2 MPPT Grid Connect(MIN 5000TL-X (AS4777-2 2020))

        Does it means the only option for me is Alpha ESS 10kWh Battery – $4,999 Installed?

        And does it requires to replace my existing inverter, or just as a AC-coupled add-on?

        • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 11:00

          Hey Mate,

          You can go with anything on the market effectively as with AC coupling we can install most batteries with a Hybrid inverter and a battery. The Alpha and Sungrow have their own Hybrids same with other brands.

          Send me a PM or email and we can chat further.

    What the best option for 3 phase 13.3KW solar with two Huawei SUN2000-5KTL-M1 - Three Phase Hybrid Inverters

    • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 09:55

      Hey @utsc,

      You can AC couple most batteries on the market to this system.

      Seeing that you have the hybrid inverter already the compatible batteries would be the Huawei Luna batteries. That being said Huawei no longer supplies these products into Aus as they supply iStore products, Huawei products rebranded.

      Ideally best to get a AC coupled solution so that you have flexibility in the battery you can get, with AC couple you can have pretty much any battery on the market as its paired with its own hybrid inverter.

      Get in touch and we can discuss your property specifics and find the right solution for you.

      Cheers,

    I'm looking forward to more information about inverters used in battery installations….
    the ability to "island" a residence from the grid (disconnect from the grid and supply power to the residence when there is a power cut) is obviously critical to many, but I understand that many battery inverter setups can't do this.
    (Clearly an inverter must disconnect from the grid if it is operating off battery power, as required by law…. otherwise linesmen get electrocuted)

    It would be desirable for an owner to be able to restrict a residence's power use to the home's own solar and battery…. many inverters restrict solar panel output when the grid line voltage is high…. resulting in a residence drawing power from the grid instead of solely from solar panels. (This is a common dilemna for remote residences operating on SWER lines (single line earth return))

    etc…..

      (disconnect from the grid and supply power to the residence when there is a power cut) is obviously critical to many, but I understand that many battery inverter setups can't do this.

      The Alpha ESS can do this, and so can the Tesla Powerwall - but note that batteries like these can only output a peak of around 5KW.
      So you can't use the battery to power your whole residence - only 5KW of it. This is more than enough to run your lights and fridge, but it's not enough to run your AC whilst you boil your kettle.

      • rooster7777 on 04/05/2025 - 23:16

        I had thought that tesla required extra anti islanding equipment and didn't do it standard, but if I'll take your word for it.

        Have you any info on the ability to select power only from panels and batteries while the grid is still active… particularly at times when high line voltage is throttling panel output?

          Have you any info on the ability to select power only from panels and batteries while the grid is still active… particularly at times when high line voltage is throttling panel output?

          That’s an interesting use case - disconnect the mains when they bump up the voltage to throttle PV feed in. You can still generate as much as you can because the reference voltage is from the battery, not the grid I guess.

          This gives me something else to ask some installers about, last time I made some enquiries, about 2 years ago, I specifically wanted it to work while islanded, to charge from the array while it was islanded, and to cold start in the morning with the juice from the array if it went flat and was still islanded. I tried 4 companies, none could give me definitive answers.

        • Nom on 05/05/2025 - 14:01

          With the Alpha ESS, it has a "UPS mode". If you experience a power cut, then you simply flick the UPS switch "On" - and voila, your house is powered from the battery, subject to the ~5KW output load limit.
          But I don't know if the panels will work and recharge the battery whilst it's in UPS mode. Maybe they will but I don't know.

          Whilst the grid is still active, your power will already only come from the panels and battery, upto the load limit. If you have 4KW coming from your panels, you can draw about 9KW from the panels and battery combined - if you're running your oven at 15KW then the remaining 6KW shortfall will come from the grid.

          Effectively, if you never draw more than the battery+panels are making, and the battery always has charge, then you will only every draw a negligible amount from the grid.

          • rooster7777 on 05/05/2025 - 14:46

            @Nom: Thanks for your reply… that sounds somewhat promising… it's a pain that the power cut switch doesn't automatically turn on, and manual switching only disables that. It means if no-one is there to understand what to do, and to turn the UPS switch on… then everything is still off… like fridges freezers etc…

            If we're understanding each other it sound good about what happens when the grid is active with the alpha… but I'm not totally convinced. I suspect it might struggle on a single grid line (SWER) which regularly has overvoltage and fluctuations….. like my fronius.

            My fronius throttles my solar panels when grid voltage is a bit high…. sometimes it might use solar power up to 10 or 11am… sometimes it has completely cut my panels off due to grid overvoltage at 7am ……after producing only half a killawasp. On my SWER line the inverter will cut right out from line overvoltage all days except dark and wintery weather. It is NOT a fast responder, so if I use some power the inverter will still be shut down unless I run something for some time… if I'm using enough power to drop the grid voltage sufficiently it will eventually accept panel input. If I try to be smart and make enough load for the inverter to allow the panels to kick in, invariably I find after a period of time that the panels are shut down again, and I'm just buying and using grid volts.

            • Nom on 05/05/2025 - 16:14

              @rooster7777:

              it's a pain that the power cut switch doesn't automatically turn on

              I assume it has to be like this, because of the battery 5KW load capability.

              If it was just in UPS mode all the time, then you'd be in a pickle if the power went out whilst your oven was on…

        Price was good from OzB and I spoke with Matt and Michael who both spent a fair amount of time on the phone explaining things to me and answering questions. I have a degree in engineering and have enough knowledge to not be BSed and these guys didn't come across as salespeople. Many others simply subcontract and have a pure sales team who go hard on trying to earn their commissions.

        Check out Solarquotes.com.au for general advice on selecting installers and for real reviews. Main points to look at are whether they subcontract heavily, years in business and customer reviews.

      That would be from $13,000 onwards plus backup another $750 assuming single phase.

      Depends on a few factors, inverter size, existing system or not and battery location and distance from switchboard.

  • Dyl on 05/05/2025 - 06:32

    Now this works out well with the free power plans if you can configure it to charge between 11am-2pm and use it during peak hours

    Assuming you charge during these hours, you only need to use around 3-4KWh/day during other times for it to be worth the ~$1.30/day it costs over the warranty period (10 years). It won’t outweigh loan repayments as you would need to use a full charge everyday during peak times / times that are usually ~$0.40KWh, but over the 10 years warranty it becomes worth it as long as it remains at least 50% efficient, which as others are rated to 90%+ after 10 years it very well should.

    @OP possible to configure charging times on these units?

    Edit: Just to confirm, it can charge from AC too right?

    • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 10:00

      Hey @Dyl,

      Yes you do have the functionality to charge batteries from the grid as well based on your needs. However there may be limittions from the electricity provider/distributor. Depending on your energy plan and its restrictions, however yes this is possible and useful if you are on a VPP or want to take advantage of low electricity rates at various times of the day.

      That being said you wont get the rebates if its not combines with a solar system, either existing or new based on the rebate eligibility. Charging from grid has restrictions with distributors so best to check.

    Hey @OP a question I had was looking at your battery options last week, Sungrow battery on your website last week was listed as from $6k, is there any difference between that and the $7.5k listed above in Vic. As I was expecting the price to come down to $3k with the Fed government rebate. Rather than increase in price? Also as the platinum offer you had the Tesla powerwall, what are they pricing up post the Government rebate installed? Cheers

    • Associatedmattcerium @ Cerium Energy on 05/05/2025 - 09:47

      Hey @Babsie104,

      Yep you are right the pricing we had previously was $6k for the Sungrow on the website and varying for other products as well. The reason for this is that those prices included the old Battery Rebate in Vic a couple of years ($2,950) ago as well as finance pricing. This was listed in the system description. There hasn't been a price increase – it’s just a difference in how the price is presented.

      With the new federal rebate in we wanted our website to reflect more accurate pricing. Prior to the rebate we have been offering the Sungrow battery for approx. $11k plus.

      Re Tesla Powerwall we are not currently offering them as a solution and haven't for a year or so, haven't had a great run with Teslas and their after sales support and warranty timeframes. AS a business we have decided to focus more on brands that are heavily involved in the Aus market with excellent support for our customers. Happy to get some pricing for you if you like :)
