    • Is it legal to charge a battery from grid? Would they even allow it?

      • +1

        How can they dictate what you can or can’t charge ?

      • +1

        Of course you can. We set ours to charge off peak during the winter when solar is low and supply us during peak hours.

        • Surely you get some charge during Winter

          • @MuddyClear: We use around 800kwh per month.

            • @meowsers: Is that your total usage? I try to save a lot and still get consume 400 kw per month 😔

      • +2

        That's the whole point, charge when power is cheap and in excess.

        Discharge when power is in demand and at high price….

        • It's so far from the whole point it's ridiculous

      • When did it become illegal to use electricity?

    • So the battery is only 14kw, it means he can only sell 14kw per day (charge it peak hours and sell off peak) . How would he make a lot from that?

      • He wouldn't, not even with micro-managing Amber. You hear these stories but nobody ever provides the spreadsheet to give it some sort of credence.

    With bidirectional charging arriving for EV's, it seems like home battery storage is something that will be a perk of owning an EV; and there is no practical need for a separate battery.

      Well, unless you need power for both your car and your house.

      • If at home then you’re not using car.

        If using car then you’re not at home.

        What’s your point?

          Lol tell us you live alone without telling us you live alone

          • @plmko: If the family is using the car then they are not at home. A family that plays together, stays together.

        • +1

          Yes if you never need to charge the battery that is fine.
          But at some point you need to be charging the car, which you won't be doing if you're discharging it. A day sitting around in the AC prevents you from being able to use your car.

          • @xmail: It’s bidirectional. It can charge and discharge at the same time. And if you have enough solar panels you can still charge your EV while discharging part of it for your home.

        • If at home then you’re not using car. If using car then you’re not at home. What’s your point?

          Ok let's just think about this a little bit.
          I'm at home, using my car's battery to power my home. Now I want to go for a drive. Oh wait…

          That was the point you missed.

          • @1st-Amendment:

            Now I want to go for a drive. Oh wait…

            Then go for a drive! Your EV is still close to full charge as you’re charging more than you’re discharging IF you have enough solar panels.

            Learn to read. This has already been explained.

              This makes no sense.

              So just think about it a little bit before posting another brain fart.
              If your solar panels are providing enough power for your house then what purpose is the battery serving?

                Given your line of questioning, which is now different, tells me you don’t understand this technology well enough to have a discussion.

                You need to stop thinking and start reading up. There are a lot of smart people working on this, much smarter than you.

                      This is the original point that you have repeatedly struggled to grasp.

                      A brain fart that you cannot rebut.

                        I have contributed plenty with my explanations. You on the other hand have contributed nothing but ask stupid questions. If you want to rebut then state the issue, and stop wasting people’s time.

                        Please explain how charging a battery at the same rate you are discharging it provides any value.

                        It is not necessarily at the same rate, which again I have explained. This further highlights your lack of ability to read or comprehend.

                          Right so here's where thinking part comes in. There's only 3 possible options:

                          1. Charge is higher than discharge. In which case you don't need a battery since your requirements are met directly from the solar panels.
                          2. Charge is the same as discharge. Again no point having a battery since it serves no purpose.
                          3. Charge is lower than discharge. Which means eventually you lose charge in you EV so can't drive it anywhere

                          Cognitive dissonance in 3, 2, 1…

                          • @1st-Amendment:

                            Right so here's where thinking part comes in.

                            At this point you need to stop thinking and start reading up on this technology. Again, smarter people than you have worked on this from it’s conception to now working proof. The irony of you continually saying ‘thinking’ is not helping you.

                            Charge is higher than discharge. In which case you don't need a battery since your requirements are met directly from the solar panels.

                            By your argument then if you have enough solar panels installed on your roof to supply enough power to meet your requirements then you don’t need a battery. Why on earth did people come up with the battery solution? Just install more panels on your roof… clearly NO!

                              Why on earth did people come up with the battery solution?

                              Because at some point they need to discharge the battery to use it. Do you understand this simple concept?
                              And if your are using your EV as your home battery and you discharge it, it means you can no longer drive your car (or the range will be severely limited). It also will shorten the life of your car because you are consuming more cycles.

                              So if you scroll to the top of this thread, that was the original point being made. If only you knew how to read…

                                I have already. Are you OK?

                                Because at some point they need to discharge the battery to use it.

                                No no no. There is no apparent need for a battery according to you. How is it possible to discharge something you don’t need?

                                And if your are using your EV as your home battery and you discharge it

                                No no no. Just put more panels on your roof. No need for batteries remember? Again, already answered. But how are you fully discharging the battery at home if it’s getting more charge than discharge? Hmmm 🤔

                                Let’s say you discharged the battery by driving the EV for some time, and you had to push the EV into the garage for charging. Then of course you can’t use it as a home battery until it gets some charge again. However in most cases there will be surplus charge in the battery that can be used for the home. The advantage of bi- directional charging is that you can charge the EV as well as power your home at the same time. I think you have been spoon-fed enough. You are either seriously lazy or mentally challenged. Pick one.

                                So if you scroll to the top of this thread, that was the original point being made. If only you knew how to read…

                                I am well aware of your stupid point, which again has been answered. You have already proven you can’t read. It’s there for everyone to see now. Congratulations

      Agree. Teslas have a vehicle to grid software unlock that they anticipate will be done by 2025. Meaning a Model 3 Long Range (for example) has 82kWh capacity for $74k and you have a car too at that price. Will be interesting if it smoothes the peak of shifts the peak till 10pm onwards. When you compare fixed battery cost vs this way. Maybe another car is better value.

      • +1

        Exactly why i bought the 2023 Model 3 Long Range.
        And waiting for the unlock and an affordable V2H wall box.

        • But long range you call only charge upto 80% which is less than RWD which can be charged 100%

          • @hopper: You can charge to 90% regularly with the long range.

    • +2

      I could be wrong, I don't know enough about it, but with bidirectional charging, don't you only get access to about 2kw? So while you have a ton of capacity, you wouldn't be able to power too much.

      • +1

        I think you are confusing V2L with V2H/V2G. V2L is a gpo attached to the actual car, and yes, that is typically limited to between 2kW and 4 kW. V2H and V2G plug into the charge port on the car and are capable of much higher discharge rates. Plenty to power the average home. Of course its all theoretical in Australia as there are no V2H/V2G chargers currently certified for sale here. Well, there was one briefly "kind of" certified, but it's manufacture was promptly discontinued after the Australian certification was received by Jetcharge.

        https://jetcharge.com.au/v2g-charging-approved-for-sa/

        And then later, this statement: "Wallbox have advised that its production of the Quasar 1 has been discontinued and that they are focusing their efforts on Quasar 2. Due to this, the Quasar 1 has limited stock and is no longer available for retail purchase."

        As an aside, the box was said to cost north of $10k, so thats a factor to consider too.

    • +1

      Doesn’t a Tesla 3 have about a 55 kWh battery? That’s approx 4 powerwalls worth in kWh.
      4 powerwals at 13k = 52k
      1 model 3 = 65k.
      Pretty good value.
      I’ve briefly looked into the two way charging and over here it’s expensive but very early days- 10-15k installed (approx 5-6k in the uk). Doesn’t currently work with Tesla either.
      Im waiting until i can charge a future ev at my own business and drive it home and power the house.
      I feel The future will have many people doing this so kWh will be dirt cheap to buy- and the power companies will charge mega daily supply charges.

  • +10

    We looked at one when we did our solar install. Every single installer I spoke to warned me off it and said the ROI was terrible unless you're somewhere remote and off grid.

    Plus I'd rather burn my money than give it to Elon Musk.

    • Yes, installing a battery for this price is not worth the return. Maybe if this was $7k installed.

        "Standard retrofit installation: $15,495 or $13,995 (GST inclusive) when you sign up to Origin Loop VPP."

        So I think deal price is incorrect. It is not saving a further $1,500 for signing up to VPP. That's already counted to bring the price to $13,995
        @mods??

  • +4

    For me. I pay 36.95c/kwh and mt Feed in tariff is 12c/kwh so effectively this would save me the delta if I export more then 12kwh everyday with a small reserve.

    0.2495 * 12 = $2.994
    2.994 * 365 = $1092.81
    13995/1092.81 = 12.8 years pay back for me.

    That's not factoring in a reducing Feed in tariff or increasing electricity prices. The warranty is 10 years. I'd like to see payback within the warranty period before I buy.

    • +2

      Also charge/discharge losses

    • you can charge off the grid in off peak and use the battery during peak too

    • +4

      and keeping $13k on an offset account would have saved $17k over 13 year.

      • people don't realise the opportunity costs at all or factor in rainy/cloudy days…

  • What is the cheapest ev that supports bidirectional charge?

    • You mean vehicle to load and grid.

      Not sure which one is the cheapest but Nissan leaf v2G and byd atto 3 V2L

    • +3

      I think an older Nissan Leaf if you are talking a defacto house battery. Still following lengthy trials in Canberra and approval that took way too long, I am only aware of one person in SA who managed to get through all the red tape to install as such - welcome to Oz! We only do innovation in govt policy documents and if we are sure no existing political donors might get upset.

    • +1

      Shame V2G only exists in SA ..

    • Besides the EV you will also need a bidirectional charger that cost $10k + installation.

      Installation is $1-2k.

      All up about $12k, still worth it?

    Problem with origin offers are that they charge premium rate for standard product that you can easily get for 20% to 30% cheaper than going with origin.

    Just few months ago this year they quoted $7870 for 6.24kw JA panel and 5kw Goodwe inverter which other companies probably do it for $3500 to $4200 roughly

    So what's point of signing up with them?

  • +1

    13.5kw is too little, I highly doubt it could last till morning, specially in winter.

    • If not using A/C heating or cooling it is plenty to last overnight.

      • +1

        Agree if lights , tv , cooking appliances and air-conditioning is off while sleeping then it probably last longer than a night… Just keep wifi modem on … LoL … !

        • I use lights, TV, cooking appliances at night and there is plenty of charge left until it starts charging again the next morning

    • All night? maybe a small .5Kw oil heater from Bunnings for bedroom.

  • I recently bought a battery, issue I'm having is it never has enough charge to run as a UPS, I set a minimum before it decides to run from grid, it's usually / almost always this low whenever the power goes out. It might be a software limitation, I just want it to run to say 15 or 20%, run from grid, but when the power goes out, use the remaining power in 'that' emergency. Anyone have experience with this? It's Alpha ESS if anyone is familiar with that software.

    • Not familiar with this particular system, but most inverters should be able to do what you want. The problem is you might not have access to those settings, only installers do.

    have PW2 with a 6kw rooftop system (had already), works pretty well… sunny days 100% off grid got the QLD govt promo few years ago paid $4500 up front $3k contribution for Govt and 10 year interest free $6k over 10 years ($50 a month)

  • Don't forget if you get interests if putting into a high interest earning account, after 10 years at 6% you would be alot better off buying this upfront now and pay $15000 as these types of technology will only get cheaper overtime

  • May be better to use that money to buy Tesla shares.

      Maybe not, too, given how many analysts are talking about insanely over-valued they are currently.

      • How about Origin Energy? Or bank shares? or ASX200 etf, or nasdaq etf, or just put the money in a high interest account?

  • Whether this even goes close to working for you is highly dependent on where you live. I'm near Ballarat and we (both working from home) would be lucky to put 2-3kWh into it daily, some days nothing at all, for months and months through the middle of the year.

    If you have $14k ready to 'invest' into green power, buy a solar panel array (or massively upgrade what you already have)…. buying a battery at these prices is not good financial sense.

    At $10k or less, yes. At $14k, your ROI isn't worth it. Battery tech is moving along quite quickly. Another 5 years in the game and the tech will be multiples better than what we have now, whereas solar panels are pretty damn efficient right now, will last a long time, and have a pay back in 4-5 years.

      Got my eyes on nickel-hydrogen batteries. If they're good enough for NASA then there good enough for muncan.

      • I know… very promising developments!

      • Can you get them even remotely close to $13k? :-D

        • I'll let you know how I go

    yawn.

  • whats the cost to replace the battery in around 10yrs?

    How Many Years Does A Tesla Powerwall Last?

    Battery Life Expectancy: Although most lithium-ion batteries last around 10 years before they start to degrade significantly (which isn’t much longer than traditional lead-acid batteries), this still means that you will likely have to replace your unit at least once within that time frame depending on how frequently you use it—and replacing a unit could potentially be costly depending on where you live and what kind of maintenance/repair contracts you have in place for your device(s).

    Beware of VPP program! You are not in control of when the battery will be charged or discharged to the grid and the amount of battery circle will be way higher than the normal use.
