UPDATED: Now compatible with Amber Electric

Score a FOX ESS EQ4800 solar battery from just $5,299 after rebates.

Pay from $5,299, dramatically reduced through government incentives (up to $16,000 for a 42 kWh system).

Available Systems & Pricing:

  • Basic| Price: $5,299 | Specs: Single-phase 5 kW inverter, 2 MPPTs + 41.93 kWh battery

  • Standard | Price: $5,499 | Specs: Single-phase 8 kW inverter, 3 MPPTs + 41.93 kWh battery

Why this deal rocks right now:

  • Battery prices are dropping: Home batteries are now being added to 1 in 5 solar installs (vs 1 in 20 just a few years ago).

  • Federal rebates are live: From July 2025, the Cheaper Home Batteries Program offers a 30% rebate, taking many systems from over $10K down to ~$6K — and this deal already lands at $5,500.

  • Real household impact: Solar + battery setups are helping families slash power bills, sometimes even earning credits.

  • Typical savings: with ~20 kWh daily use and $0.40/kWh electricity cost, you’ll save about $8 per day and usually recoup your investment in under 2 years.

        • Jackson on 30/08/2025 - 21:32
          +7

          I am looking at a Fox ESS setup as we speak (10kw 3 phase) and I was advised the inverter only supports 10kW supply, and I was advised that if you try to enable whole home backup and ever exceed that, it will trip and that will take down your power more often than you are likely to have a power outage. I am not 100% sure I understood the bloke but that's what I took away.

          In my case it would be rare for me to ever use 10kW at once unless I was charging both cars and had the AC on and cooking, but he was reticent to connect it to more than just lights and my GPOs. To be honest this is fine for me anyway really, because it would mean I can exist normally, internet on, can work, tv fine, and if I was cold I can just run a small heater somewhere, and I can cook on gas in n the backyard (unfortunately I don't have a park bbq over the fence)

          • UltimateAI on 11/09/2025 - 14:24
            +1

            @Jackson: You also need to consider the per phase limits. The 10kw is basically a peak for AC/DC conversion under ideal conditions, expect it to be lower like around 7kw.
            With 10kw, you can likely do all powerpoints + lights, but you should leave off the EPS ports;
            - Oven, A/C, Fast EV Chargers, Pool Pumps\Heaters, Water Heaters

            Sure you can put more on, but you are just asking for trouble. It's perfectly safe the inverter will trip and protect itself.

            Also note, EPS is not UPS there is often a small delay in switchover, so computers might restart, clocks reset. Just managing expectations.

      I think the T&Cs don't allow free charging for EVs and wall battery. But they can't stop us. But it's easy for them to tell if we pay 0c for the usage, isn't it?

      Click the link, their warranty info is halfway down the page.

      MPPT, or Maximum Power Point Tracking, is a technology used in solar systems to optimize power output by constantly adjusting the electrical operating point of solar panels to extract the most energy possible under varying conditions like sunlight and temperature. It works by tracking the Maximum Power Point (MPP), the ideal combination of voltage and current for maximum power, and significantly boosts the efficiency of solar charge controllers and inverters, often increasing energy transfer by 20-30%

      You can read up on facebook energy groups/reddit/whirlpool etc. General consensus is if your needs are basic and happy to take the extra risk of issues then the plus is it'll pay itself off fast. A higher quality and more capable battery solution, for example a 3 phase 48kw stack with Sigenergy, Sungrow, BYD etc will set you back low 20K from my research. Big difference in cost. But, they are much better solutions.

      • Captain Hindsight on 30/08/2025 - 17:30

        Thanks I guess it depends on your definition of what’s better. I’m looking for a reasonably quick payback as I may move in five or six years plus I don’t see much point getting a top notch system that takes 15 to 20 years to get money back.

        • Xizor on 30/08/2025 - 17:46
          +3

          Whats better is whats better. But what is suitable for your requirements is entirely another matter, and its great your looking at it from that angle. Assuming you already have solar panels and understand your power usage profile across summer/winter and overnight, from my reading the more reputable budget options are Sungrow, Goodwe, and Alpha ESS. Everything else is higher risk profile trade off i read too many negative things about that stopped me from bothering to read into them further. My situation is 3 phase, want full backup, limited roof space, want total freedom to use power how i want and no plan to move having started a family, so my requirements pushed me towards Sigenergy as the most suitable. So certainly take my remarks with a huge grain of salt and read further into other brands than i did.

          • Captain Hindsight on 30/08/2025 - 17:52

            @Xizor: From what I can tell neovolt is also a reputable budget brand.

              +1

              @Captain Hindsight: I disregarded VoltX as local support is, or was then, basically non existant. I think components wise they are similar to Alpha ESS, but they at least have some local support. Increased risk with either no doubt, but if i was going down that path id go Alpha personally. Its all risk / reward balance. I may think differently if i only had to live with it for a few years, or i was single phase so everything were simpler.

              • WhyAmICommenting on 30/08/2025 - 19:37

                @Xizor: Single phase NeoVolt 20kWh and I started well before the rebate announcement. They are almost impossible to get hold of, as I’ve got a couple of things to still sort out. Luckily it’s all working but the solar reporting is wrong due to a CT mixup.

    If i recall these FoxESS batteries had some warranty condition where it had to be serviced every year? I could be wrong or its changed but yeah just make sure you go on eyes open for these cheaper / more basic battery solutions. They have their place but its easy to end up in buyers regret down the road.

    • great-price on 30/08/2025 - 17:25
      +2

      From my research, I believe they removed that condition. It used to say something about an annual inspection required after 5 years had passed, but the current warranty document no longer says that.

      • Xizor on 30/08/2025 - 17:28

        Good to hear. Things like that are such a drag.

      • supersabroso on 01/09/2025 - 20:52

        Are you sure it doesn't say that any more? Where is the link to the current one? All the documents regardless of version state that you have to pay for an annual inspection after the 5th year so it's really only a 5 year warranty. Every year after that will be a cash grab to get it extended. If you are referring to the warranty they give you in the quote, it's the wrong one as it only covers things that they aren't selling. This must be the gotcha for the cheap price as both the installation and product only has a 5 year warranty included as opposed to 10 years by the VoltX deal.

    Great prices. Got a quote from them recently for their Ultra Plus package. Their add-ons can increase the price quite a bit. I was quoted $300 extra per backup circuit (after the included two circuits), $500 extra for DC coupled. In my case, that added $1,700 to the price (six circuits backed up and DC coupled).

        While I agree you should not discharge 100%, as of last week Fox updated the Firmware and Specifications to allow 100% DOD formerly 90% for EQ.
        This is no doubt purely to maximise federal rebates.

      Standard prices for FoxESS, in VIC the Plus pack (AC-Coupled) is about <$8000 including blackout protection, bollard, smoke detector, switch upgrade…

      NSW is cheaper, I think they can claim some additional state rebates.

      • Bigboomboom on 30/08/2025 - 20:49

        It's the other way around, VIC has Solar VIC Rebates while NSW only has Federal Rebates. The more rebates = retailers pushing price up = you ends up paying more. It also helps NSW has bigger solar market, more demand but even more supply.

        Yes it should be the KH10
        Looked at this battery lots over last 24 hours, I believe the best way is to get an RS485 to ethernet adapter and then connect it to your home assistant server that way rather than using it via ethernet.

        From what I researched plugging it into network via ethernet does not allow as much control as using modbus rs485 usb adapter
