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 just got told the $500 discount is INSTEAD of the referral code. So not sure what happened there or is it just my salesperson?

      Ok - I pressed the sales guy - he confirms due to overwhelming demand, the referral bonus has been postponed since 1 august.

    For those looking at DC coupled setup and replacing their existing <10kw inverter, bear this in mind. I've been quoted $350 in additional cost for it from another installer.

    Effective 6 February 2023, the GSD requirement applies to:

    New solar PV or battery systems with an inverter capacity of 10 kVA or higher.

    Existing systems upgrading or adding capacity, where the total inverter capacity becomes 10 kVA or more.

    Replacing a non‑warranty inverter in a system already sized at ≥ 10 kVA.

    • tunzafun001 on 06/08/2025 - 14:40

      I cant get my head around the DC coupling option. I currently have a DC coupled inverter with small battery. It has blackout protection and will charge from the sun while in blackout (this deal being AC coupled doesnt).

      They said I can keep my existing inverter, but not the battery. I cant for the life of me see why not?

      The current inverter simply see's DC (either from the panels or battery). So if the panels can stay connected then so should the current battery.

      The AC coupled system would be 'down stream' on the AC side and controlled by its own Eastron CT meter.

      So I should get my 5kw from my existing inverter + 5kw from the new AC coupled system.

      They say they can't leave the existing battery, but cant give me a reason why not (and happy to leave the exiting inverter in place)??

  • lewisoz on 15/08/2025 - 14:38

    @VoltX Energy

    I understand if I have these batteries installed outside and the temperature reaches above 40 degrees that the battery warranty is void. Is this the case?

    Regards
    Lewis

    • tunzafun001 on 15/08/2025 - 15:01

      I remember it being around 50C… which would be based on the thermosensors inside your battery.

      BUT… if it is mounted anywhere facing the sun, the thermosensor will 100% see more than 50C eventually.

      For reference, I just checked the surface temp of a chair sitting in direct sun with an IR gun, which is sitting outside today in mixed winter sun. The temp is 68C. Im in SA.

      I also have batteries on an eastern wall under the eaves getting no sun. They got to 49C last year (that I saw). Could be an outlier I missed.

      In summary, even 50C is probably not going to stand up against the ACL, as the warranty is not fit for purpose in Australia.
      But whatever you do, dont mount it anywhere near sunshine. It will go into the 60's and beyond.

        • keejoonc on 22/08/2025 - 16:05

          you have to have an installed system and apparently they send you a referral link after installation.

          If you just PM people and send them your details, even if you have a system installed, it's not following their referral policy so won't be eligible.

          That's how it was explained to me.

  • dtingy on 22/08/2025 - 14:39

    Called them today. Got a quote of $7410 that includes 30kW battery, hybrid inverter, 2 bollards, smoke alarm (will be installed into the garage), fire protection and blackout switches. Adding all these up the price seems like other budget brands. The guy on the phone mentioned to DIY fire protection sheet, smoke alarm and bollards from Bunnings. I am hesitant to DIY just in case if I need to claim from insurance in the future that these aren't installed by professional.

    • keejoonc on 22/08/2025 - 14:44

      Don't you have somewhere you can install outside?

      • dtingy on 22/08/2025 - 14:51

        I did considered this option however, due to new housing estate the land block is very small that only 900mm on the side and other location will be a fair bit of cabling where inside the garage will be back to back of the switchboard.

  • 3dprintdeals on 08/09/2025 - 20:55

    What's everyones thoughts on the 50kw with a 5kw inverter from Offer 1.

    All the Facebook posts say its oversized, just maximising the rebate.

    To add another 5kw inverter costs $2100.

    • postman on 09/09/2025 - 10:57

      If you plan to get the VPP benefit, you're limited to 5kw export, but if you don't care about the export, better choose the one with the best value / quickest ROI.

      • 3dprintdeals on 09/09/2025 - 11:01

        Yeah, planning to go Amber VPP.

        I guess for the extra 20kWh of batteries & backup for $700 is worth it, even with a 5kw inverter.

        I know another inverter could be added later on.

        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.

    • tunzafun001 on 09/09/2025 - 21:19

      $2100…I'd look elsewhere.

      The 5kwh inverter should do 10kwh when the battery is charging at least..ie 5 to the house and 5 to the battery. Once the battery is charged, then it's 5kwh max.

      Next year…all battery inverters will be 10kwh min I recon.

      • 3dprintdeals on 09/09/2025 - 21:22

        actually it was quoted at $2300

        Additional Neovolt Inverter 5kW ( SPB5k )
        Neovolt AC couple 5kW inverter SPB5k * nv-inv-5k-1p-ac *
        AU$2,300.00

        What do you mean that it should do 10kWh when it only has a 5kWh inverter?
        Do you mean in combination with 5kWh solar inverter from panels?

        • tunzafun001 on 09/09/2025 - 21:36

          When DC coupled it will do 5 to the battery 5 to the house.

          • 3dprintdeals on 09/09/2025 - 21:55

            @tunzafun001: ok, but these are AC inverters

                @tunzafun001: thanks for taking the time to reply.

                I thought the hybrid inverter is still 5kw.

                Hybrid is still 5kW - https://www.ozbargain.com.au/comment/16737722/redir

                • tunzafun001 on 10/09/2025 - 10:47

                  @3dprintdeals: The 5kw applies to the AC side. It can only process 5kw max AC.

                  But it can also process 5kw DC to a battery (as long as you have enough solar panels). Not may know this.

                  I have 8kw of panels, and am currently sending 5kw to the grid and 3kw to the battery.

                  • 3dprintdeals on 10/09/2025 - 10:58

                    @tunzafun001: I see, in my case I only have 6.6kw worth of panels.

                    I probably need to upsize my solar system and switch to hybrid inverter at the same time then?

                    • tunzafun001 on 10/09/2025 - 11:09

                      @3dprintdeals: Depends on need.

                      6.6kw has efficiency loses over time/ shade etc. So you would rarely see it export more than 5.5kw I would think.

                      If you don't draw more than 5kw at any one time, then the stock inverter is fine.

                      But I believe the inverter has 3 or more MPPTs (you add a string of panels all facing the same direction per mppt).

                      So you probably can add a string of panels if you have the roof space.

                      We used to only have 3.8kw of panels. When the battery was installed, I added an extra string in left over space and now have 8kw total. Works well for our needs. 3.8 wasn't enough (full electric house + car).

                      Car charge + Aircon put us over 3.8kw. But 5 is just enough. Literally sit on 5kw most of the day. Inverter actually does 5.3kw. So we use 0 from the grid.

                      • 3dprintdeals on 10/09/2025 - 11:29

                        @tunzafun001: My usage is currently quite low, 0.5kwh and peaks with washer/dryer but I would start using more aircon/heating once I have batteries.

                        I'm thinking of doing Amber VPP to use up the battery capacity and that got me thinking about additional inverter.

    I originally signed up for their neo vault 30kw battery and inverter which i was told my installation will be around November.
    Is sofar the same/similar battery?

  • Ace26 on 07/10/2025 - 09:46

    Looks like there is an all new type of battery system now available. Modular and has 3 phase inverter option. Wonder if those who ordered from this deal are able to upgrade. I am guessing the price of the new system would be a lot more so upgrades would be cost prohibitive.

    I finally had mine installed yesterday and received the final invoice, but the referral bonus doesn’t seem to be automatically included (even though it was confirmed prior to installation), so definitely have to chase them to apply the bonus manually.

    Also I now have 2 x 5 kWh inverters but they seem to be charging at a maximum of 2.9 kWh rate for each inverter. Is this normal? I thought I should be able to charge at 10 kWh rate with 2 x 5 kWh inverters. Is there a setting that limit the charge rate that I might accidentally turn on? @VoltX Energy

    • clartan2015 on 09/10/2025 - 12:43

      depends on how much your solar system is producing. are you also charging from grid?

      • kokartoa1 on 09/10/2025 - 13:21

        Solar system is the standard 6.6 kWh, but I am charging from the grid (using the free charge window from GloBird Zero Hero), so was hoping I can draw at a maximum rate of 10 kWh to charge during the free time.

    • 3dprintdeals on 09/10/2025 - 12:46

      what was your total price with the 2x 5kwh inverters?

  • master phi on 18/10/2025 - 20:02

    I just had mine installed on Friday last week. It was a strange install as Voltx arranged for the installation and said that my main switch button was too old for the blackout and it had to be changed I said how much they said around $300 I said okay as I just wanted it installed.

    Come installation day the electricians said that they didn't have the blackout equipment? I called up the rep as that wasn't what was in our agreement and then this time the rep said it would be $400, again I said just get it done with the blackout as we agreed.

    So suddenly the electrician could do the blackout and he put in the new main switch and did all the blackout stuff as the invoice $600 extra for that blackout feature.

    Come a week later I receive an invoice with the main switch as an extra of $300 which was expected but now I am disputing the extra "connect blackout cable to sub board" as they want to charge me an extra $400 for the blackout I had already paid $600 for. They claim it was extra but the main switch and sub board were actually directly opposite sides of the brick wall and they didn't even need to drill it was a simple cable pass. They did upgrade the RCDO for some reason when the two circuits we had connected were already RCDO perhaps this is what they wanted more money for?

    The system itself is working fine but they seem a bit scammy in trying to upsell stuff or trying to avoid what was signed. I would say be aware that they will try to make excuses to upsell as this was my experience.

    • tunzafun001 on 18/10/2025 - 23:04

      Did they have to get the grid provider to pull the main fuse to fit a new main switch? If so, in SA, SAPN charge $400 to simply pull the fuse and put it back in when complete. Basically 2 call outs at $200 each.

      • master phi on 19/10/2025 - 21:35

        No they did not. There was no call outs and it was all complete after a full day. They did everything themselves (the installers).

      • thestig on 20/10/2025 - 00:03

        I'm waiting to get this done for a smart meter installation but haven't been told there is any cost involved. Were you told of this cost before the work was done?

        • master phi on 20/10/2025 - 10:53

          I already had a smart meter. The only issue that I was told before they rocked up was that my main switch was too old and needed replacement which was $300 for the backup circuit. I assume if you don't need the backup circuit then you don't need to do this.

          Then on the day the installers said they couldn't do it ??? then when contacting VoltX again I was told it will be extra to connect the backup and was told it would be $400 then suddenly they could do it. Could have been a dodgy installer I don't know nor do I care as it is up to VoltX to handle their jobs as quoted.

          Still in dispute for this extra $400 cost as this was not told before the day and also it should've been included in the backup cost as they didn't do any drilling for it and the cabling was standard as the subboard was through the wall on the opposite side. I guess $400 charge was for an extra 2x30 cm of copper cable? As I observed they did install two new RCDO for the two backup circuits however it was originally already RCDO in those circuits so not sure why they did it except maybe to justify the extra $400 charge.

          • tunzafun001 on 20/10/2025 - 12:16

            @master phi: If they replaced the main switch, they would have disconnected the incoming from the street. Price seems to line up perfectly.

            • master phi on 27/10/2025 - 07:52

              @tunzafun001: Just to clarify so people don't get the wrong idea I am not in SA. There were only two extra charges on the invoice that wasn't initially put on the quote i.e. part under the "variations".

              The extra charges on the invoice was $300 was the main switch which was agreed before the installation date and was explained why it was required and what needed to be done reasonably.

              The second extra charge for the backup connection to the sub board $400 was not agreed before the install date nor was it explained why the charge was so much or why it wasn't included in the backup circuit price. This was resolved with Voltx but it was disappointing that this information wasn't included or explained properly and so it caused my dispute.
