Great price on a 10KwH AC coupled home battery system which includes installation. The battery also includes a 5kw inverter.

Australian guy from SA posted his experiences over six months on reddit. He worked out the ROI was 6 years without even installing solar, as he just charged up his home battery on off peak power at 8c/kw during midday. Then used the battery to draw power for the evening and night. Rinse repeat.

His posts are here https://www.reddit.com/r/AusFinance/s/606GQLsOKZ

Great info and commentary in his posts.

Had initially been waiting for powerwall 3 but this could be too good to pass up.

    Guy on reddit installed two and worked out the ROI was 6 years without installing solar by just charging up on off peak power at 8c/kw.

    Assuming rates/plan dont change and not taking into consideration battery degredation

    • samfisher5986 on 09/08/2024 - 19:58

      I assume battery degradation is calculated using the battery warranty.

    • Ellllllys on 09/08/2024 - 19:59

      Feel free to read up on his Reddit overview. He’s very transparent. According to him the battery cycles cover 22 years of use at daily charge and discharge rates.

        Rates will never stay the same.

          No one said they would. If you look at long term trends in energy prices they don’t seem to be going down.

            @Ellllllys: So you have to account for that in calculation. And also hope they dont can the plan in 1 years time which leaves you with a large paper weight

                  @easternculture: The smart meters installed on everyone’s power boxes over the last few years? The surplus of solar into the grid from 10am - 4pm. You tapped into the news, buddy? You reading?

        I'm being lazy. Does he include the internet that could/would be accumulated at ~7%pay on $6k?

        Especially if you have a homeloan, interest is very significant on ROI calcs.

        • killingtime on 09/08/2024 - 23:40

          If you want to take into account cost of money (which you definitely should), you should use the long run average interest rate, not 7%. Over the life of this interest rate could be down around 2% like it just was, or up at the current level or back down

      • coxymla on 09/08/2024 - 23:37

        22 × 365 ~= 8000 cycles

        Doubt.

    • Nom on 09/08/2024 - 20:14

      Rates/plan only change upwards anyway - so this potentially reduces the payback time.

    • Grok on 09/08/2024 - 20:19

      Let’s do the math.

      Assume 8c off peak versus 33c peak

      Save 25c per Kw x 10 = $2.50 per day

      That is $912 a year

      $5900 / $912 = 6.5 years best possible case as we didn’t count losses as the battery is a max of 97.3% efficient

      After that you have a 6.5 year old battery “free” nearing end of battery warranty while system and parts have 5-year warranties so are out.

      Meanwhile you could have invested that $5900 in a sharemarket ETF for 6.5 years.

      • Nom on 09/08/2024 - 20:22

        After that you have a 6.5 year old battery nearing end of battery warranty

        Which is now paid off, and costing you nothing, and will probably run for another 10 years.

        • Grok on 09/08/2024 - 20:25
          +1

          Maybe

          Or just one repair outside of warranty, and everything except the battery is out of warranty already, and you could go negative.

            @Grok: Yep. Silly investment throwing 10k (with no solar) like the guy on reddit with alot of unknown factors to account for

          • Nom on 09/08/2024 - 20:46
            +1

            @Grok: Maybe

            Or by the time you hit the 6.5 year mark, your off peak is now 12c and your peak is now 50c - so you've actually done a lot better than when you thought your rates would stay at 8c/33c for 6.5 years 😁

        Maths is solid, but you've made some assumptions.
        - power prices will not stay the same over next 6 years and are unlikely to decrease
        - the ETF investment is a good theory, but then you have to consider the higher power prices and capital gains tax, if you don't invest in a battery.
        So it's not as black and white as you put it. Not over such a long period.

          • Grok on 09/08/2024 - 20:56

            @Grok: Lots of variables,

      • holymackerel on 09/08/2024 - 21:11

        AC coupled battery solution you cannot discharge less than 20% of the total battery capacity. So technically you can only use 8kWh of a 10kWh battery.

        Batteries of all types, even LFP needs 10% of power as reserve at all times, and the PCS (or inverter) needs 5% as back up at all times (but most round to 10%). So if you research all AC couple battery solution, you can’t set the battery to discharge more than 80%.

        Please also note the BMS or PCS system use some battery power too. Like maybe .5kwh a day. Only DC coupled batteries use DC power to power the PCS/BMS so there is no loss in battery power.

        • flashi007 on 09/08/2024 - 21:35

          I can change this percentage on my app for my battery. Mine is at 12.5%

      • ezzaf on 09/08/2024 - 21:42

        He's in SA and his peak rates are much higher.

        Yep if you read my other posts… 75c/kwh between 5 and 9. 33c is the shoulder. 51c second peak between 6 and 9. Off-peak 10 til 4 @ 8c

        I've similar in SEQ, 60c difference between peak and off peak. Tariffs vary a lot from place to place, don't assume others are paying the same rates you are.

        • Grok on 09/08/2024 - 22:58
          -1

          Don’t you have to choose to be on a time of use tariff?

          Who would choose 75c kWh peak? I pay 33c

          I read that SA had the most expensive power in the world and the least reliable. That’s socialism for you.

      Yup OP Please add to description
      $1600 rebate after installation and paying $7500 up front

      Location Availability

      Installation Period
      This rebate is valid on the first 300 VoltX Neovolt Battery Systems installed between July 21 and Oct 31 2024.

      • cheekymonkey on 09/08/2024 - 20:33

        Well that makes bit of a difference to the deal, 8f you don't live in NSW

      • Hank Scorpion on 09/08/2024 - 23:19

        hmm, the home battery scheme kicks in on 1 November, the incentive is between 1600 and 2400 too so is this an early incentive by the government or subsidised by the manufacturer?

    • purple1 on 09/08/2024 - 21:58

      You must also upload the image of your review on Product Review and/or Google. See their claims page.

    Couldn't find much info on what type of chemistry these are. The price is tempting but I'm dubious of unknown brands with unknown warranty support, when it comes to batteries

      Who doesn't want to strap a bomb made out of unknown batteries to the side of their house?

      Personally, I'm just going to wait for the big boys to start competing, they're going to have to sooner rather than later.

    ROI was 6 years without even installing solar,

    I dont have solar, i dont have a battery.
    I only churn.
    My ROI so far over 2 years is over $4k. Havent paid electricity in that time. Into my third year and already have $300 credit which will pay for my next bill.

      You don't have to choose just one :)

      My return over 2 years has been $3.5k from solar and $2k from churning.
