*Price includes GST. Does not include delivery, installation, or other costs and fees. Final price will be provided by a Certified Installer.

Keep in mind this price is before installation and delivery.

That said, in the US the PowerWall (PW) 2 and PW3 have been the same price. Yet the PW3 includes an inbuilt inverter.

PW3 has 11.5kW of continuous power and 13.5KWh of capacity.

Once the NSW government battery rebate hits on 01.11.24 the price of these could drop to around $11k installed, which seems to be reasonable since most people are pretty much giving away their solar to the grid now.

The other thing to keep in mind is that you can recharge from the grid. So if you use OVO you can recharge from 11am - 2pm for free (though that’s when you solar will be pumping) and you can also recharge the PW with offpeak power from 12am - 5pm.

The downside of the PW is that it’s not modular, unlike the other two which are highly rated by Solar Quotes, the SolarGrow and BYD home battery systems. Where you can add a few KWh of storage easily and (potentially) make use of falling battery prices.

          What's so good about PW3? I'm yet to go down the rabbit hole for solar batteries… I don't suppose it uses BYD blades in them?! Lol, I just read an article saying Tesla has started putting BYD blade batteries into Tesla Y's in Germany so far with good results. And there's a good chance I'd buy one just for that in the future if no other new battery tech gets released by then. BYD blade batteries are just that good I believe.

            @Ultraman: When I was doing a look into batteries, I found out that the batteries in Tesla's are LFP (not necessarily blades) in the standard range and NMC in the longer range models. NMC batteries are more energy dense so they can take up the same amount of volume but provide a better range.

              @Caped Baldy: NMC have a significant risk of turning into a fireball if something goes wrong.
              LiFe have far less risk of turning into a fireball, and charging to 100% doesn't degrade the battery.
              The new tesla powerwalls in the US market are LiFe… NMC is going to die a fiery death like plasma TVs in most applications.

        Ive just read this and started researching now and see the PW3 has an inbuilt Inverter.

        I'm just wondering what benefits do you gain if the solar battery has an inverter when you already have a standalone inverter (mine is a fronius)

        is the inverter part in the pw3 self sufficient or does it also require grid power to run it meaning if you lose power youre still only going to have power if you have some charge in your battery?

        how can this be cost efficient if the battery also includes an inverter since my inverter alone was a few grand I guess won't that make the battery even more expensive?

        cheers

        • rookie317 on 05/08/2024 - 13:08

          To be clear, the PW2 has a built-in inverter (DC to AC), any AC-coupled home battery does. Another component not usually advertised is the battery charger (AC to DC). These components make them independent of solar system.

          The PW3 has a "solar inverter", this just means it can take solar input (DC) via what is usually called (MPPT) charge controller. This component isn't nearly as expensive as your usual stand-alone solar inverter. The PW3 can be connected directly to your solar panels, there are some advantages doing this:
          - Efficiency: AC coupled battery system: solar panels (DC) -> solar inverter (AC) -> house switchboard (AC) -> battery charger (DC) -> battery banks/cells (DC) -> battery inverter (AC) -> load (AC); while PW3 is just: solar panels (DC) -> PW3 charger controller (DC) -> battery banks/cells (DC) -> battery inverter (AC) -> load (AC).
          - Oversizing: PW3 can take up to 20 kW of panels – which should be allowed under Australian ‘oversizing’ rules because it can reportedly also deliver 5kW direct to the battery. To be clear, any DC coupled battery will allow this, but you will also need a compatible hybrid inverter.
          - Simplifying installation/design, less components, less points of failure.

          Both PW2 and PW3 needs the Gateway to work independently of grid power.

        • NigelPearson on 05/08/2024 - 19:12

          Theoretically, less loss, so higher efficiency.

          Every time you convert from DC(solar panels), to AC(external inverter), to DC(charge battery), you lose a few percent of energy as heat. Also, if they are replaced by one device, it is able to react slightly faster to changes in solar generation and household load.

          In terms of component cost, any battery system already has an inverter in it,
          to convert the battery's DC into AC to drive your home appliances.
          What the PW2 didn't have in it was the MPPT and DC to DC charge controller.

          Time will tell which is more reliable; seperate components, or an all-in-one (hybrid) inverter.

          Hopefully we start to get bigger community batteries sometime soon.

          Yep, but it's not in the grid companies interest to have local storage. they should have been connecting compressed air/gas turbine storage years ago. But maybe we'll all get those magical SMR that Nuclear Pete is promising in every suburb.

          Batteries are for if you have constant power outages, not otherwise.

          they're handy that's for sure. although I don't believe Powerwalls work during an outage, do they? Most domestic configurations don't because you need a grid isolating inverter otherwise when the power stops in the street so does your inverter & battery.

If LG has a 90% capacity on 10yrs, that would indicate they're pretty confident that they'll laat at least that long.

                  I just noticed powery power charges have goe up.from 23.5->28.5c/kWh, so that'll reduce the payoff time, but around another year.

                    No doubt the tech has improved since 2022, but it seems dangerous to assume your battery will outlast its 10 year warranty.

There would be plenty of situations where people have huge bills (my family included - old house, poor insulation, 3 very young kids, etc) that a battery can help.

            For 99% of people, the only reason to consider solar and/or battery is to generate more money than it costs.

            And for any financial investment that you want to make a profit from, of course you're going to run the numbers. Trying to make a profit without running the numbers, would be madness - you might make a loss !

        I’m not sure about that. Had a pw2 installed March 2021. Bill used to be circa 2k/yr. Probably more actually. I haven’t had a bill since then, am currently at $1800 credit. This winter I’ve been using my ducted AC throughout the night, which runs the battery empty by about 4am. Despite this, it’s stilll saving me money.

        Cost about 12k. Savings so far 6k minimum of bills plus almost 2k credit. So 3 years in 8k “paid off”. On track for a 5yo payback period.

        I have a pool, large (35kw) pool heater (heat pump), ducted AC and a decent solar system (15kw). The key is a big enough solar system to pump charge into the pw in winter. Plus automation.

        September to May, my pool varies in temp between 29 degrees and 33 degrees (I like it warm lol). The only behaviour I have modified is to ensure I don’t exceed the pw2 5kw output limit between 2-8pm for which one moment of excess consumption applies for an entire months charges.

        Point is, plan it and do it right. It can work out financially viable pretty quickly.

          How do you charge the battery in winter when it’s raining/ overcast? Off peak?

            @Jono05: I think you missed the 15KW Solar system. Even on a cloudy day, it's going to generate close to enough to fill the Powerwall.

            The weather needs to be spectacularly bad to drop the output close to zero.

            @Jono05: Sometimes you can’t avoid it, the system gets depleted and there simply isn’t enough solar to charge the battery or even to use at all. Generally speaking, bad days I can generate 20ish. A good day I can generate 130kwh. If the weather is so bad that I can’t charge, I reserve whatever I can for peak use to minimise charges there, and fall back to the grid. It has happened once, and because I’m so far in credit, I still haven’t had to pay. Some nights I opt to leave the aircon on all night, once the battery is depleted, I use from the grid.

            Automations and planning will cover and offset 99.9% of usage. I feel for redundancy and never needing to rely on the grid a minimum of 50kwh would be needed to be ok and cover a rainy week/really shitty dark weather.

      Consumer ➡️ Elon ➡️ Trump. Pass

        It's hard to think of a more terrible candidate for POTUS than Trump but I think Elon would probably edge him out.

          I think he was saying (correctly) that Elon is pumping $45m a month into Trumps campaign.

            @BlahBlahBlaah: You're expecting her to make an alliance with russia….. to grab every man on the poossy…. to go for an unbeatable world record for crimes while in office…. to incite insurrection….. or do women scare you?

          Given that Musk was born in South Africa, he will never be a candidate for POTUS. Phew!

            @Cheapskate Paul: He probably doesn’t want to anyway. He’s a lot more intelligent and productive than Kamala Harris!

            Never say never. Things can change pretty fast. There was a time we thought felons couldn't be candidates yet here we are.

            (For a while, while he was a Kennedy, I had suspicion Arnie might be the first to challenge the born in the USA rule.)

      Weak. I donate any excess I have to Elon. It helps offset the hot air from haters rofl.
