Australia Tesla Powerwall 3 Specifications | Three Phase Backup?

[@LudicrousFeed]

Thank you Neerav Bhatt for recording the Australia launch of the Powerwall 3 and for his article in solar quotes Links below: Tesla Powerwall 3 vs PW2 Australia - Installer & Media briefing kzbin.info/www/bejne/m2TQhaWFfbOfh9k Australian Powerwall 3 Unwrapped: More Juice, More Dollars, More Questions www.solarquotes.com.au/blog/powerwall-3-launch/

[@NeeravBhatt]

Thanks for the shoutout Tom. I agree the new PW3 is best suited to new installs of solar+battery. The increased cost / kWh compared to PW2 makes it less compelling for owners of existing solar

[@LudicrousFeed]

My thanks goes to you Neerav for recording the presentation given I was not able to attend! 🙏

[@robsengahay5614]

Interesting that 4 Powerwalls is 54kw of storage which is the same as a Model 3 but at $13,600 each plus installation this home storage literally costs the same as the car which tends to suggest that the profit margins are massive on these.

[@emmett3067]

Yep. These batteries should be about half the price they are.

[@LudicrousFeed]

It’s no coincidence that Tesla’s energy division is one of the more profitable arms of the company and most likely the reason why it is hesitant to enable V2X in its vehicles

[@paulwalker2133]

@@sheepyracing2774definitely overpriced but with feed in tariffs disappearing and prices going up they’re starting to look fairly cost effective. Again, assuming they last 10 years plus.

[@forgetfulduck]

Recently got a battery system. Did look into the power wall 2. But it just didn't provide enough discharge capability or backup to justify the price on 3 phase. Ended up going with a sungrow system using their sh15t hybrid inverter. Have off grid back up on all 3 phases 5kw per phase total 15kw. On grid capability is full 63A per phase. The limitation is my battery at 9.7kw discharge. But is modular. So can increase capacity and discharge. Its pretty cool having full house backup including the AC in a blackout. Switchover is seemless, flick the breaker switch to test it. No appliances dropped out.

[@LudicrousFeed]

Great having that three phase backup 🙏

[@ltt5988]

Hi Tom what is net metering and how do you know if you have one? Thankyou for your informative videos.

[@LudicrousFeed]

Pleasure 🥂 Here’s an older video I did explaining how the PowerWall integrates with three phase homes thanks to the magic of net metering: EXPLAINED - Tesla PowerWall2: Integration with 3-phase power kzbin.info/www/bejne/j3Wpl6SnoaZ9e9k

[@ev-mojo]

Thanks for the awesome breakdown of the Powerwall 3. The built-in inverter and LFP chemistry are definitely big wins, and that 11kW output is awesome! The lack of true 3-phase support is a bit disappointing, but the net metering workaround is still handy. Like you said, the upgrade decision is tricky - it's all about weighing those upfront costs against long-term savings.

[@LudicrousFeed]

Pleasure! Lots of factors to consider when deciding whether to upgrade or not

[@TassieEV]

The pre-heating option can be useful in some parts of Australia. For example this past winter in the central highlands of Tasmania there were some days where the low temps were down at -17c with daytime highs around -8c and these were back to back days not random ones.

[@LudicrousFeed]

Yes there will always be edge cases for which this will be useful 🙏

[@mark123655]

On the Economics. The combination of lower FIT, higher Peak/ Demand charges and the future likelihood of Export levies.. actually reduces the payback on a battery system versus previous electricity tarrif structures

[@LudicrousFeed]

True, less opportunity cost lost with filling up the battery rather than exporting

[@markwilliamson9199]

Thank you very helpful. I have a 3 phase house with 3 phase aircon. I just signed up to AGL for a PW2 for $11950 installed. However they also offered I could wait for a PW3 if I want too (for a few $$ more of course). My issue with having only one phase backup is that my 2 fridges are on different phases, plus my lights are also split across all three phases, so I have to pick and choose. I have commented on the Solar Quotes page also.

[@LudicrousFeed]

During a blackout, plug both fridges into a circuit on the Powerwall phase via an extension cord if necessary

[@sanjaygupta666]

Get a Goodwe ET series 3 phase hybrid inverter with F series battery - it solves your problem

[@beforetheinternet]

I had the circuits in my meter board reconfigured a couple of years ago to optimise what stays backed up on my PW2 in the event of a grid outage. Some circuits that would not be backed up were shifted to the backed up phase, other circuits that we cared less about were shifted off the backed-up phase. So fridge, instant gas hot water, microwave oven, internet, lights in the kitchen and lounge room, garage door and TV/computer circuits will stay on. That’s the basics covered, the rest (like air conditioning and vehicle charging, upstairs light and power) we do without until the grid comes back… I wouldn’t want to waste power running those anyway during an outage, you need to maximise the amount of time you can cover the basics.

Or a Fronius hybrid plus BYD battery gives 3 phases backup and apocalypse mode

[@xiaowei1]

We finally got a battery (not a powerwall), and we did it just in time to get the rebate in Qld (which only lasted a few months). With the price of electricity during peak hours (now 53c per kw) and FIT prices for solar falling hard, it seemed like the time to jump in. We ended up with a Franklin which was on special at the time. It has a 13.6kw battery and cost us just $7,000 installed - after collecting the $3,000 rebate. With our usage, it will save about $5 to $6 per day. So that is close to $2,000 a year. I thought a pay off a bit under 4 years made it worthwhile. The price for the battery has since gone up, and the rebate has gone away. So it's back to about $15,000 installed, which would take 8 years for us to pay off. At that price, I'm not sure I could justify the cost. Of course, everyone's usage differs. The reason i mentioned the above is because we have 3 phase power and have experienced a blackout since installation. The battery took over as it was supposed to, but it did take about 2 second to kick in, so everything cut out for a bit - which I was not expecting. Perhaps this was because our house has 3 phase. The blackout was only lasted a few minutes, but we had power. Perhaps the difference is we had certain things put onto the single phase that the battery sits on (all lights and plugs), but not the car charger, stove, central aircon, and hot water. because the battery outputs at a constant rate of 5kw, we just did everything we would normally do. I don't know how the PW3 is integrated, but i would have thought it was installed in a similar way.

[@LudicrousFeed]

Wow great price! At $7k it’s almost a no brainer 👏 - Yes we also have key appliances (fridge) on a circuit sitting on the same phase as the PW2 so in the event of a blackout, the food and milk doesn’t spoil

[@xiaowei1]

@@LudicrousFeed So i guess i didn't quite understand that the PW3 is not set up for 3 phase? Also, does the PW2 or 3, kicking when the solar starts up again in the morning - i.e. the battery powers the solar to start up (if there is an ongoing blackout). I thought this was a good feature for the Franklin battery, but the reality is the last time I ever saw this happen would have been about 40 years ago.

[@LudicrousFeed]

Correct the PW3 does not provide true 3-phase functionality or backup but it can integrate into a 3-phase system via net metering. The PW2 can continue to charge and discharge on its own phase during a blackout with adequate solar … presumably PW3 will function in a similar manner

[@MarksElectricLife]

Like you Tom, I don’t feel compelled to upgrade but as a first battery P3 is an awesome package! I don’t find single phase backup to be a problem. All my essential loads except A/C are backed up and tbh I wouldn’t run my A/C in a blackout since it would greatly reduce the backup time.

[@LudicrousFeed]

Yup good point, I also don’t feel the need to run the AC in a blackout 😁

[@raymondschembri5042]

Yes , now Tesla cars need to be VT HOME /load and have a complete sustainable home.

[@LudicrousFeed]

@@raymondschembri5042 That would be awesome but would that replace the need to buy a home battery? 🤔

[@oldchev2850]

Tom I noticed one Q&A question was, will it be rated to 9.99kw in Australia? I think on solar installs, in Queensland at least, this is done to ensure the system isn't a 'dynamic connection' system. That is, the inverters are rated at 9.99kw as 10kw and above have a dynamic connection whereby the providers can remotely control the output of your system. I wonder if you had an old system that has a 10kw inverter and installed before this came to effect, would buying a powerwall put you under this new ruling? I remember reading somewhere that if you install a battery, then your whole installation becomes a 'new installation'? I dont know how a dynamic connection system would affect you if you had a powerwall battery but i presume thats what that question referred to. I would like to know the implications if this is the case

[@LudicrousFeed]

Ok I was wondering about that question but your explanation has helped to clarify it. Yes it would be good to know for those with bigger systems in Qld and other jurisdictions where this ruling would be applicable

[@joelfreitas7230]

Great Video Very informative, Yes Net metering does zero out your export solar against your consumption of the home. However if you have 3 phase power coming into your home. You load will be spread over the 3 different phases and your battery will be only connected to 1 of the phases. This means the other 2 phases at night will feed of the grid. The best work around it move all your load into the same phase as the solar and this will eliminate any of the night consumption until your battery runs out. I had a electrician come out and test all my load and then moved everything to the same phase as my battery and I noticed what I was using from the grid almost when to zero.

[@LudicrousFeed]

Good strategy 👍

[@Noah-oz6dv]

@@joelfreitas7230 wrong, powerwalls output additional power to offset usage on other 2 phases.. all you’ve done by moving all you circuits onto the battery phase is unbalance your houses load which that electrician should know doesn’t comply with as3000

Nice one! Congrats 🙏🥳

[@xJI00]

I’ve heard that whilst the gateway is still required now, this will be going away. Do we know when this will likely change ?

[@mondotv4216]

Technically a single PW3 could never backup a three phase home. It will be interesting to see if Tesla can get 3 x PW3 working for 3 phase backup. This is the route a lot of inverter companies go down (Victron for example) - each inverter gets locked to the incoming phase and if the grid goes down - the inverters talk to each other to keep the phases in correct relationships (120deg out of phase) and gridform the 400V supply. Most 3 phase hybrid inverters do the same thing within the unit - ie they are essentially 3 inverters in one and this does lead to compromises - ie a 12kW 3 phase inverter (with some exceptions) can only supply 4kW per phase.

[@LudicrousFeed]

Yes having the batteries on different phases talk to each other in an outage to form a true 3-phase solution out of sync would ideal

[@kdkd693]

I really like my Victron inverter in the motorhome, but didn’t consider for my 3 phase home as they are indoors only install. Plus wasn’t sure how 3 inverters would report a total for simplicity

[@steveevans8506]

Absolutely we will be going to the Everything Electric show in Sydney next year and will be upgrading our current system to all new Tesla solar panels and a minimum 1 powerwall 3 with at least 1 expansion pack. We currently have a 12yr old system (4.4kw pv) that is locked into a 44 cent /kwh buy back until 2028 so we were waiting until there was a suitable system that would replace as much grid reliance as possible as we would loose our solar credit payment as soon as we modified our current system.

Wow great setup! You may need more solar if you’ve got the roof space to fill those batteries …

[@lynnwilliams3408]

Thanks Tom Have 8.5kW of Enphase inverters for past 11 months after upgrading a previous small solar system. I was waiting for NSW government subsidy to kick in around November to get a PW2. Aside from LMP and max output the PW3 does not seem to be much benefit in Sydney. The included inverter in the PW3 would I guess also be irrelevant if installing new microinverter system like Enphase where AC rather than DC comes of off each panel.

[@LudicrousFeed]

Yes that’s true about microinverters which I already have on my roof. You wouldn’t need the inbuilt string inverter in the PW3 for that setup

[@Kiwigeo8339]

The PW3 will be able to handle input from a microinverter PV system but I believe maximum AC input is limited compared to the PW2. I have a 14.4kW Enphase based PV system and a PW2. Replacing the PW2 with a PW3 is not a good option for me.

[@fallonstuart8921]

I just completed a full year with 13.2 kW solar, PW2 and the OVO EV plan, charging an MG ZS EV and a Tesla MY RWD. House total imported was 4852 kW and solar exported was 10,618 kW. The net cost was -$20.42. New plan from OVO has FIT reduced from 8c to 3.3c, so I'm expecting about +$450 next year. I think I can mitigate some of this with more car charging at lunch time. One question I have re the PW3 is can it charge during a power outage?

[@LudicrousFeed]

Thanks for sharing your stats 🙏 Good point about it being more economical with reducing FiTs - With regard to your question about the PW being able to charge during an outage … presumably the built in solar inverter is single phase so yes it should be able to charge in a blackout. However, for three phase solar systems, if you are using the AC coupling to connect to a third party three phase inverter then the answer will be no, it won’t be able to charge in a blackout

[@alexb9498]

Hi Tom, like the video . there was bit about PW2 being 5kW continuous and a peak output of 7kW, I had my PW2 for 2 years now and before it was installed I made sure it was the updated model that could go up to 7.5kW continuous and a peak output of 10kW i think by memory, earlier PW2 couldn't get this option regards Alex

[@LudicrousFeed]

Oh ok nice! 7.5kW continuous is a significant jump!

Tom, Would new solar system install be cheaper seemingly inverter no longer required?

[@LudicrousFeed]

If you watch Neerav’s recording in its entirety, the Tesla team went to great lengths to convey the ease of installation of PW3 compared to PW2 so logically speaking the reduced complexity and therefore cost of installation should hopefully be passed onto the consumer 🙏

[@mrgreen271]

I would be interested if the solar inverter can be curtailed by local config. With negative FIT this will be important for future. I can currently do this in my fronius but challenge with tesla is local management and needing to rely on a VPP provider. I think a seperate inverter is probably needed for curtailment.

[@LudicrousFeed]

That's a good question. I suppose with software anything is possible in future updates but at present this cannot be done with the current Tesla App

[@saberianamir]

You mentioned the output of 11kw can cover the EV charger at max power of 11kw... Correction: model 3/Y can only charge at 11kw on 3 phase. It's max power is 7kw on single phase which is how the powerwall will be connected anyway. So on single phase you'll be able to charge model 3/Y at 7kw with 4kw remaining for other needs in the house.

[@LudicrousFeed]

Ah very wise and good pick up 🙏

[@gregb1599]

Lol, the Powerwall will be empty in less than 2 hours using it to charge any EV. It is better to use an EV with V2L to power essential items in the house. Most can do 3.6kw except the Nissan Leaf that can do V2H/G at 7kw. Our Kia EV6 has a usability capacity of 74kwh or the equivalent of 5.5 Powerwall 3

[@sanjaygupta666]

Hi, will the Powerwall 3 charge from solar in the event of a blackout, or when it’s depleted that’s it until grid is restored. Three phase property, from my understanding only one phase active during blackout. Thanks

[@LudicrousFeed]

If you’re using the built-in inverter, it should be able to charge the battery during a grid outage and you’ll have backup on that phase only. If you’re using a third party three phase inverter then you will have only what’s remaining in the battery during a blackout but it will not recharge. That’s at least how it works for my PW2

No three phase backup is a complete foot-gun. Basically eliminates it as an option for myself unfortunately. Back to the Victron plans...

I guess, I really want to know whether it is worth getting the PW3 because I have 3 phase

[@LudicrousFeed]

For three phase solar systems, it will behave in almost the same way as the PW2 ie. during a blackout, the battery will back up the same phase that it’s on until it runs out. Unfortunately it will not supply your three phase solar inverter (or any other 3-phase devices) during a blackout

[@hwajuhwarang]

@@LudicrousFeed I am not 100% on what that can mean. So a phase will do one or more circuits, ie lights, fridge & power points (1), another phase may do oven and another light circuit and a 3rd phase do the garage? Then the PW3 will only supply one of those phases during a black out? Like light and fridge circuit? During said black out, does the full (up to 20kw) solar keep charging the battery? Does it also keep direct power to one of the phases?

[@LudicrousFeed]

@@hwajuhwarang check out my explainer video from a few years ago: EXPLAINED - Tesla PowerWall2: Integration with 3-phase power kzbin.info/www/bejne/j3Wpl6SnoaZ9e9k If you have a 3-phase solar inverter (which given the size of your array you most likely do) then it will not charge the battery during a blackout

@@LudicrousFeed I don't have any solar or battery yet, just got 3 phase recently and in the middle of contemplating quotes for solar plus battery, 2 of which offer PW3. I watched a your video on how 3 Phase works, and given I need it for the garage but my solar panels and battery will be on the house, does that mean the house can just be on single phase and that the solar can still charge the battery, just nothing for the garage? Your chalkboard shows the solar feeding direct to battery then kitchen, this suggest that maybe during a black out, the battery will still receive charge from solar. Thanks for your time.

[@LudicrousFeed]

@hwajuhwarang You have to decide which circuits you want to be on the same phase as the battery. Otherwise in a blackout it won’t be supplied by the battery. If you really need the battery to be charged by solar then I suggest getting a micro inverter setup rather than a three phase inverter. Best to speak to your installer

[@beforetheinternet]

Tom - you should do a video on battery degradation in PW2. While most PW2 owners say theirs is fine, I’m not so lucky and it’s likely mine will hit the warranty replacement threshold next year (7 years old). I’m not worried about it though, because it means I get a new battery with full capacity for free 😄

[@LudicrousFeed]

Yes that’s the trade off I suppose with degradation! How did you check its true capacity? Is there an easy way to do this?

[@beforetheinternet]

​@@LudicrousFeed you need to be a bit of a geek and find out by interrogating the PW2 directly (it has its own local API). If you google there’s some articles explaining how to do it. There’s a parameter called ‘nominal_full_pack_energy’ which tells you current capacity in watt-hours. I’m down to about 73% of original capacity, 30% loss inside 10 years is the warranty threshold.

[@LudicrousFeed]

Cheers, it’s worth doing before my warranty expires in a couple of years 🙏 Edit: I just used the NetZero app which showed my degradation at 6.2% after almost 7 years. Will follow up with a full video shortly

I have a 3-phase Solar Edge inverter. Will a Power Wall three power all three phases via my 3-phase Solar Edge inverter during a blackout? I assume that in installing a PW3, it will bypass its inverter and use my Solar Edge inverter?

[@LudicrousFeed]

Because the Powerwall 3 is not a true 3-phase battery, unfortunately it will not supply power to your 3-phase inverter during a blackout. What occurs in a blackout is that you will be able to use whatever charge is left in your battery to supply the same phase but your solar (via three phase inverter) will not be able to recharge the battery until the grid supply is restored. Hope that makes sense

[@greghoughton6189]

so in a 3 phase powered home, can the power wall 3 keep the lights, internet and fridge running in a blackout? sorry - not up with the tech jargon

[@LudicrousFeed]

Provided the fridge is on a circuit that is on the same phase as the Powerwall. In a well balanced home, the lights will stay on for the circuits that are also on the same phase as the PW. You can always plug the router/modem into the sockets that are on the same phase as the PW. Seems to be a recurring theme here … 😁

[@AshParajuli86]

Other than the advantage of having power during the occasional power outage, the economics of getting this is not convincing with the constant decreases in the FIT? How long would it take to recoup the initial investment? Also, would Tesla offer the older PW2 at a discount that it might be more economical to get PW2 instead of the latest PW3.

[@LudicrousFeed]

Actually ironically, with decreasing FiTs it may improve the economics and payback period given there is less lost opportunity cost associated with a high FiT. I agree if Tesla can discount existing PW2 stock then it may be worth looking at 👍

As as existing PW2 owner, adding a PW3 doesn't make a lot of sense. Adding a second PW2 gives you almost the same peak output as a 3 (10kw vs 11.04) but double the storage. It seems a strange decision from Tesla not to make them play nicely together.

I was on 2c/kWh for the past couple of years. It’s supply and demand economics. If there’s no market for excess solar in the middle of the day because no-one can use that electricity, then why should you get paid anything for it? In fact, soon it will cost you to export it at certain times of the day, because there is a network cost in dealing with excess generation that no-one can use. The value in rooftop solar is in the value of the grid electricity it replaces during the day, not the solar export.
