All the Latest on Tesla Powerwall 3 - The *New* Standard for Home Batteries

[@GaryDoesSolar]

* NOTES SINCE PRODUCTION * I've had a questions from a couple of viewers asking me if I have received any compensation from Tesla for this video. I can confirm I have not received any compensation nor benefits from Tesla for this or any other videos I have made. And that I'll always mark videos as "Paid Promotion" should that ever be the case.

[@artisanelectrics]

Great Summary Gary! I met with Tesla at the recent Intersolar event in Munich and Tesla Energy reps have told me it is LFP chemistry. Also good to note - PW3 has G98/99 approval for 3.68/5/6/7/8/9/10 & 11.04 kW (Not 11.5kW FYI) which means that even if the DNO places some restrictions on import/export at your home, you should still be able to have Powerwall 3 installed, just with a restricted charge/discharge rate. We are on the Tesla Powerwall 3 Installer Training in a couple of weeks time so will be posting a video update on our own channel in the coming weeks, but delivery estimates are for October right now so we are encouraging people to get on our waiting list as we anticipate high pent up demand. Those with PW2 who want to expand their capacity might consider doing so sooner rather than later as sales of PW2 will be phased out in the UK at the end of the year as PW3 starts to roll in. DC expansion for PW3 should be coming in Q1 2025 hopefully...

[@GaryDoesSolar]

Thanks for the great feedback. Video should go live tomorrow. Hope you had a great time in Munich - I used to be there a lot with my day job (in the mobile industry). Sounds like it was a good show! Thanks for sharing the insight regarding PW3, and I look forward to your video post the training! Agreed, anyone thinking about a PW3 really does need to get on the waiting list now, to secure a (reasonably) early installation date. Artisan's website is www.artisanelectrics.co.uk

[@farmerpete6274]

I had a Powerwall 2 and solar installed in May this year, here in the UK. Despite the poor weather, I have been virtually 'off-grid' since then - though I have to advise that my solar panels are in the perfect position. The Powerwall 2 just does its thing and the app is great. Totally recommend it so far, will be interesting to see what happens over the full year.

[@satellite-image-deep-learning]

As a tesla M3 owner I’ve had a great owenrship experience and am leaning towards a Powerwall 3. Your comments about the price being expected to fall as demand levels out are giving me a reason to wait a bit longer. Perhaps even waiting a year I will save considerably!

[@GaryDoesSolar]

I'm hoping to get a Tesla one day, and so will look forward to the experience you are having! It's hard to predict the future, but lithium prices are dropping like a stone this year, so I expect that to be reflected in battery pack prices before long!

[@synthmaker]

@@GaryDoesSolar I bought a used Tesla M3 with 58k miles just over a year ago. You'd be surprised how cheap they are used. I never thought I'd ever be able to afford one. They have little wear and tear and very little maintenance required so great to buy used. It's been amazing and I don't know any other car that compares, even other EVs. Just have a look at autotrader, for £15k you can buy a 2020 Model 3 like mine. If you have an ICE car you might save over £200 every month that could go a long way towards paying for the car if you get a loan. In my case I'm actually saving money compared to my previous 2015 Kia Diesel. For a while I was driving to work in central London costing me 50p return in electricity and less than £2 to park all day on the street instead of my £13.90 train ticket, every single day, just saving on train tickets it was already over £200 per month on top of driving at 2p/mile which since the 1st of July has gone down to 1.75p/mile. Do your proper research taking everything in account like not having any scheduled services, not needing to change oil, timing belt, event brake pads and they're hardly used, no road tax, no ULEZ, no congestion charge etc etc. You'll be very surprised.

[@paulkearsley9509]

Thanks Gary, I've recently had a give energy battery installed, 11 Kwh, and is working fine so far. I recently had my latest bill for the month and my use was priced at £1.00 and change. However my standing charge was over £15.00. Gutted!! 🤣🤣

[@GaryDoesSolar]

Yeah, the UK government needs to fix the standing charge as soon as possible - so many elderly and vulnerable people are being disproportionately affected by it! And of course, it goes against the whole notion of homeowners trying to mitigate their grid pull.

[@matthewhuszarik4173]

I have had the Power Wall 2 for four years without a hiccup. I live in California and got the Power Wall because of the risk of losing power during elevated fire risk periods. Well I haven’t lost power once since I had my solar and Power Wall installed.

[@GaryDoesSolar]

That’s a great case study for the product - thanks for sharing! 👍🏻

[@Oceanabubble]

Gary just wanted to say that your videos are great and you as a person are very easy to listen to , I’ve learnt a lot so thanks . I’d also like to say that if anyone is looking for more energy independence you will need at least 2 Tesla batteries . I live in north wales roof SSW is a sun trap all day. If I didn’t have two batteries I would still be needing some grid power all through the summer . Have 12 panels and solar edge . But most of the uk has days that are cloudy and wet all through the summer and you just don’t get enough power generated to last through those dull days . Also all my appliances are new and of the highest energy efficiency . Personally I prefer being off grid , I’ve seen very irregular readings , what I would call criminal activity readings off the Tesla app and frankly don’t trust others being able to access and control my system and potentially doing anything they like with my power .

[@TheTobster79]

As an existing Powerwall 2 owner, I would raise a slight issue with your use of the word “seamlessly”, when talking about the PW taking over in the event of an outage. It’s definitely noticeable in the home: PCs will restart etc. If one simulates an outage, and manually isolates the house from the grid using the Tesla app, that is indeed seamless, so if someone was aware of a planned outage, then the blip could be mitigated against, I guess, but if it’s unexpected, I believe the cutover time is in the region of 20 ms. In fairness to Tesla, they don’t claim it’s got UPS capability, and I think the only current domestic solution (available in the UK) which does offer UPS is the Sigenergy SigenStor.

[@rubenconzales9718]

I have a PW2 and live in a rural area with frequent power cuts in NZ and mine is pretty much seamless. Just wonder if there is a glitz with your install?

[@GaryDoesSolar]

Worth getting your PW2 checked... In any case, I believe the PW3 is seamless.

[@JunYamog]

It’s not UPS like but definitely you are not aware of power cuts unless you are staring at a light bulb. Granted that we are mostly laptop, even the fiber optic modem is kept up, and heat pumps. It’s a fraction of a second enough for the residual left electricity on the circuits not to reset the appliances. If your takes a second or more have the installer check his work.

[@bob210912]

I have Powerwall 2's as well and agree with this. The Powerwalls are not UPS and if you have a power outage it is not seamless backup. I have had to put small UPS units on some of my equipment to over come the delay. I spoke with Tesla support about this and they confirmed that there will be a delay in the Backup coming in if there is a heavy draw at the time of the Power outage. When I was sold the system I was told that it was seamless backup which it is not!

[@philbuckle]

I installed a Tesla PW 2 about a year ago here in Melbourne Australia. In the first 6 months we had 3 power outages. For us it was a seamless experience and on 2 occasions I didn't know it had happened until the app told me. In all cases my computer (Apple Mac) just "soft blinked" and kept going. I run a recording studio at home, I don't want any interruption to the power supply. Part of the installation was fitting another fuse box that takes over from the regular one when the power goes out and the battery kicks in. I assume that all installations do this?

[@SteveLoughran]

This looks quite appealing-and I agree with your “wait till next year” recommendation. In the meantime I’m going to have to see how I can connect my existing AC solar power feed directly into the unit -so I can retain that 40p/kWh FiT kick back I get. Alternatively: work out if/how I could use metering within the powerwall to measure the exact amount of energy supplied by DC coupled solar. Given our inverter is about 13/14 years old I should be planning for that soon anyway

[@richardvivian3665]

I’d advice people who can wait a year or two to do so. The cost of PW3’s will reduce significantly and guaranteed there will be some glitches with the first year or two’s models that need ironing out.

[@GaryDoesSolar]

Cheers Richard - yeah, I'm expecting PW3 prices to fall in line with declining lithium battery prices generally - great news for anyone looking to buy a home battery!

[@ianollmann9393]

We have two power wall 2s. There are plenty of times we wish we had more storage, but all of these times happen because we don't have enough solar generation. I'm pretty sure if we doubled or quadrupled our solar production, then we'd really just need enough storage to get through dark hours and quite frankly if the battery depletes itself at 4AM, we may not notice.

[@GaryDoesSolar]

Thanks for sharing your experience, Ian. Yeah, I can imagine that with products like PW3, and battery prices continuing to fall, that over the next 3-5 years, people (including yourself) will steadily expand their storage capacity to the levels you’ve quoted 😀👍🏻

Innovation, innovation, and more innovation. Thanks, Gary. Other systems are possibly cheaper, but this stands out, and for me [in the UK], Octopus integration is key... now making my investment in the GivEnergy AIO under scrutiny. And if your DNO would not allow you to have that level of output to the grid [limited] one could even consider going off grid with that capacity

[@GaryDoesSolar]

Hi Kristian, yeah - I do like it that Tesla is showing the way for other manufacturers to follow. As it happens, I'm meeting with a number of DNOs in London next month, and I'll be quizzing them about how they determine export limits for domestic properties...

[@ians3328]

[@wajopek2679]

These appliances are complex in nature so having good hardware and software that “just work” is just as important and it costs. US companies such as Tesla/Enphase have fewer anomalies as Class Action lawsuits ensure they fix issues quickly and effectively unlike some mfrg entities in far east.

[@GaryDoesSolar]

I agree, and good point about the lawsuits.

[@EcoHouseThailand]

Tesla PowerWalls are quite a bit more expensive here in Thailand but Chinese Batteries using CATL LFP cells are only £160 per kWh. I am off-grid with 20kW of PV 36kWh of domestic batteries and my BYD Seal’s V2L adding extra backup when needed. The feed-in tariff is only 5p/kWh with 5kW of PV max allowed (Videos of my setup on my channel)

[@GaryDoesSolar]

Wow - that's a great price for batteries!

[@yesido-trouwfotografie]

Hi Garry, would you like to make a video about the Enwall from Enercap? This is a solid state battery, which will ultimately become the future. The specs: 100% DOD, 500,000 cycles and no degradation the first 15 years. I don't think 99% RTe is possible with converting ac-dc-ac. In any case, specifications are mind-blowing!

[@GaryDoesSolar]

I’ll take a look. Thanks for sharing 👍🏻

[@speedbird300]

Specifications are both a little too good to be true (99% RTE) and also vague and poorly worded. It claims to be a hybrid solution of graphene, tantalum capacitors and sealed cells. No mention of what is inside the sealed cell. Their website has some schoolboy errors on it. I think they’ve got a way to go to be convincing

[@IanB61]

Great video as always Gary. I'm surprised you didn't compare to the Givenergy All In 1 which I would have thought a direct competitor at 13.5kw, UK company and cheaper. Just to clarify the Tesla will cope regardless of straight DC from the roof or using Enphase inverters to AC ?

[@GaryDoesSolar]

Thanks Ian - I wanted this video to be just about the PW3, really. And I'm sure other channels will make comparisons to other similar products. To your question, yes, let's say there was 16kW of solar, the PW3 is able to put 5kW DC into the battery and convert and output the remaining 11kW to AC.

[@mikeforwarduk]

[@zalllon]

13.5 kWh wouldn’t be enough to power any of the homes here where I am in Canada, especially in the peak of summer and in the peak of winter. We would need three times that for single days use. Why the power wall is a pretty product, there are much more economical options out there that provide similar interface experience and automations. And for those that might have a little bit more interest on the tech side, you can do even better in terms of affordability.

[@GaryDoesSolar]

Yeah, agreed - for those who know what they're doing, there are less expensive ways to build a large home battery capacity.

[@rozonoemi9374]

It depends for how long. I'm also in Canada & it is sufficient for my needs. Emergency power & cheaper to run on Powerwall than prime time energy rate until I can charge back at low price after midnight.

[@robrs210]

I have a powerwall2 and yes they are good and suites my needs. The powerwall3 rolls everything into one. This is not in my opinion great, unless they are absolutely reliable. The reason is the powerwall3 is battery, inverter and solar pv all in one. I would like to know if there are any failure modes that would allow the unit to still run some of the system. As I have had a solar inverter fail before I’m not keen on loosing everything in the system with a fault. That said if they are doing battery unit extra capacity (dc) that would reduce the cost of extra kWh’s on your system. Oh and the power backup switch is nice bonus, yes it’s been used a lot due to out area supply

[@GaryDoesSolar]

That's a great point - I'll see what I can find out...

[@andrisromanovskis9363]

Thank you! Informative as always. One question that could be illuminated in a further video re: PW3 is - what if the customer needs 3-phase home power?

[@GaryDoesSolar]

Cheers for the great feedback! My understanding is that 3-phase support is coming early next year :-)

[@Belgium_citizen]

A very good question, because a lot of residential heat pumps are running on 3 phase. As such people need to heat home or warm water in a backup way.

[@geoffreycoan]

In the UK 3 phase is still quite uncommon although I know some people are being converted to 3 phase when they have solar fitted as this is the way to avoid grid export restrictions that they’d get on single phase. Not heard about 3 phase heat pumps, I have two large heat pumps and they are on the same single phase

[@99ReasonsY]

hi garry, yes i used your referal code one question i have give energy allinone, can i add the tesla PW3, is tey any way its possible

[@GaryDoesSolar]

Thanks very much for using my referral code - very much appreciated! Now I wouldn’t recommend adding another battery from a different manufacturer because they’ll end up fighting with each other. One day, there will some standard for communications between solar, battery and other related products, but today each manufacturer has their own communication ecosystem, which is closed to other manufacturers…

[@JohnR31415]

Depends how you set them up…. But they’d likely end up shuffling energy back and forth between themselves if you aren’t careful.

[@jimave]

I’m a Tesla fanboy, so of course I like the PW3. I live in Fresno, California and I have a 7.695 kWp solar system installed by Sun Run in 2018 by the previous owner. I want to add 2 PWs and my quote is about $22,000 before federal and PG&E incentives. Probably about $14k after the incentives. I can’t justify spending $14k when my annual true up is less than $100.

[@GaryDoesSolar]

That's fair comment. I'm expecting home battery prices to continue to fall over the next year, which might help with the justification...

[@PeterGagen]

Well, I can see you seem very convinced by the Tesla products. I have no experience for them but the certainly sound good to hear you speak about them. You aren't on their Sales force are you?...:-)

[@GaryDoesSolar]

Hi Peter, yeah I really do like Tesla products, and am happy to tell you I don't have any commercial relationship with them, nor have been asked to promote their products.

[@geoffreycoan]

Great specification, looks to be giving other battery manufacturers a real run for their money. Tesla do have a reputation for products just working out of the box unlike some other competitors where things like multi-battery setups are “coming soon” and there are still firmware issues. Of course any product is subject to teething problems but Tesla probably have a bigger testing budget than others. Considering that it includes a high capacity inverter, the price isn’t too awful

[@GaryDoesSolar]

I agree. And the UK price seems to be similar to the GivEnergy AIO.

[@jonasgustavssonaland]

Does it have an open API so that you can monitor and control the battery for us who are on energy providers that are not supported? Does it support 3-phase systems?

[@GaryDoesSolar]

I don't know about how open the API is, but Tesla has certainly opened it to selected energy providers. I suspect it will be made available to consumers in time. Regarding 3-phase support, I understand this is coming early next year.

[@stuartdodson1752]

Gary, Powerwall 3 is not the "new" standard for home batteries. Tesla is finally choosing the LFP chemistry. There are other companies out there that are on their 10th generation of a Lithium Ion Phosphate residential battery. I am glad to see that Tesla has finally embraced the better, longer lasting, better performing battery chemistry. Also, make sure to read the fine print. Tesla batteries are built for self-consumption and backup. I believe they also have to be tied to solar, not direct to grid. The actual trend for energy storage is grid-tied batteries that complement solar. Batteries need to do much more than just simple backup. They must become resources that are to be used and leveraged daily versus wait on a grid outage. That is the only way to transition to a smarter grid and more responsive energy services.

[@GaryDoesSolar]

Good to debate on this. My argument in the video is that the following specification is ideal for the mass market: - single unit - 13.5kWh battery storage - 11.5kW continuous power output - Circa 30kW peak power output (for starting AC units) - built-in string inverter with 3 (or 6) MPPTs handling up to 20kWp of arrays - Full home backup (including continued solar generation) To make a persuasive counter argument, perhaps you could identify products with a higher specification than this, or why any of these features are not important.

[@stevencarter9401]

I believe that Tesla are running a virtual system which you have to sign up to but they can then remotely switch you battery to the grid in times of high demand...

[@smartLooser]

I was at the Intersolar in Munich and talked to Tesla technicians about PW3. 1. among other things, the AC battery is not yet available and expensive in Germany. Prices are only announced by the installer. 2. if you have a PW3(1) with 3 MPP string and add another PW3(2) with MPP, the PW3(2) must also be supplied with PV power. In other words, lay new cables and connect them to the MPP string. Otherwise it will not charge! This is a major problem, as the installed solar modules are usually connected to the PW3(1). Conclusion: PW3(1) cannot supply PW3(2) with power! PW3(2) needs its own PV modules and possibly new cabling. In my opinion, this is a negative point when it comes to expansion.

[@mshackleton1]

you wouldn't connect a second PW3, you'd connect a DC expansion though.

[@GaryDoesSolar]

I'll try to get some more information on this. The most obvious solution for that requirement is to add a DC Expansion instead of another PW3, I guess...

[@smartLooser]

@@GaryDoesSolar yes and no :-). With one PW3 you get 11,5kW output. With the 2. PW3 you want and get 23kW output. If 23kW is needed (or more) you have to make a plan B.

[@GaryDoesSolar]

@@smartLooser Ok, let me do a bit of digging around that then - it does seem a bit of a restriction... Thanks for highlighting! 👍

[@smartLooser]

How much is the Power Input from Solar for each PW3? And what is the Peak Solar for the storage? May be you install 15kW on the roof. What would happens with that energy… a. empty 13,5 kWh storage b. 80% of 13,5 kWh full c. 100% full Question: the house needs 16kW, can one PW3 delivers it? I have 3 PW2 at home: this system delivers 12,9kW plus all 6kW solar.

[@markbamford5065]

Hi Gary, great videos. UK based, is it definitive that we will be able to mix PW2 and 3? A friend has a PW2 and is wanting to add another battery for capacity only. What do you recommend please

[@GaryDoesSolar]

Thanks, and yes, PW3 compatibility with PW2 coming very soon! As your friend already has a PW2, then they could simply add other PW2, no?

[@user-ol6rd7pl5t]

Hi Gary, what would be needed to run an average UK home plus an EV with a little extra in reserve that could run the home & car for all or most of the year off grid or as much as possible.

[@GaryDoesSolar]

That's a tricky question to answer as it depends on other factors too, like your monthly generation and typical usage...

[@genuinecomments4008]

I am an installer and it won’t reduce the costs as they guys are there anyway. Even if it takes 2-3 hours they would need to be able to do 2 installs in the day so they need to be close together otherwise you can’t. I must admit using it as a UPS has its issues. I have doubts that’s the right way.

[@GaryDoesSolar]

That's interesting to hear - thanks for sharing!

[@airtyke]

Thanks Gary - another great video. I'm potentially looking for a battery only solution with Octopus Intelligent Go but install may have to be outside. Do you have any thoughts on how that could impair performance? I know my EV car range degrades significantly in cold weather and wondered if the same applies here?

[@GaryDoesSolar]

Hi @airtyke - thanks for the kind words :-) Worth watching this video I made about how lithium-ion batteries manage in the cold: kzbin.info/www/bejne/m5C1f39maN6hmZIsi=GdtnXl6JbepaYwNc

[@jvlivtriple]

The shipping container my new Powerwall 3 arrived in last week had Lithium-Ion warning labels on the outside. An indication of battery chemistry?

[@GaryDoesSolar]

Great that your Powerwall 3 is on its way. Now, the lithium-ion label alone is not an indication unfortunately, as both NMC and LFP are variants of lithium-ion. I think you can be confident from what everyone is saying though, that your battery will be LFP.

[@etorqueaus]

Garry you’re a wealth of information! Can you tell me how compatible the Tesla power wall 3 would be installed at a residential property with 3 phase power? I’m in Brisbane Australia and have a 19.8 kw solar array (54 panels) that produces 120 kWh plus on a good sunny day, and 20 kWh on an overcast rainy day. I only get 5c per kWh exported and pay over 30c per kWh I purchase overnight.

[@GaryDoesSolar]

Thanks for your kind words! :-) Now, for the situation you describe, I think PW3 would be eminently suitable come next year, when 3-phase support is added. PW3 is able to accommodate an array of that size without problem.

[@etorqueaus]

@@GaryDoesSolar Thank you for your reply. I will continue watching your channel and hold off just that little bit longer to see the 3-phase support added. Cheers!

[@JohnVanderbeck]

With the built-in inverter does that allow the Powerwall to be charged directly from a DC bypass of sorts, more efficiently, and then the inverter just does its job on the power going to the home? Or is it still going DC->AC->DC for the battery?

[@GaryDoesSolar]

With the built-in inverter enabled, PW3 behaves like a DC Coupled battery.

[@oddballbender]

What is the difference in price with dc expansion. I was wanting to use tesla powerwall completely off grid. However if octopus can control the system, then would a grid feed allow octopus to charge batteries when electricity is free occasionally? Assuming solar array large enough to charge array in the meantime?

[@GaryDoesSolar]

From what I've heard, DCX is at least $1,000 less. In terms of Octopus controlling the PW3, it would be the same control as with other battery manufacturers, like my own GivEnergy system - and for those, I believe Octopus would try to charge batteries when the wholesale price is low (e.g. free or negative).

[@oddballbender]

Perfect, thanks Gary. Love the channel. Top vids

We're in the process of getting the Eco4 grant for solar & heat pump. This grant doesn't permit hybrid inverters or batteries. So I'm looking for ...perhaps the Powerwall? Will V3 be able to do some diverting to an immersion heater for HW?

[@GaryDoesSolar]

Hi Steven, did the grant say why hybrid is not allowed? Bear in mind that the built-in inverter in a PW3 is hybrid. You can still divert excess solar to an immersion heater irrespective of what inverter and battery you use as it's a separate system - see my video here for details: kzbin.info/www/bejne/bKvGYppnl99jm6Msi=TDP7g2vP86ySbnx3

very often the main reason to purchase a battery is to save on energy cost, so cost of the "premium" product, however good is quite counterproductive.

That's true. If financial return is the primary factor, then there are far better solutions than the PW3. For example, I came across this video the other day, which is the cheapest approach I've seen to date: kzbin.info/www/bejne/l3mYipKdf72Cqassi=OPcWWytAx3a3OsNy

Yes, I would have. Tesla make solid products that just work. I’d pay extra for that 👍🏻

[@robsengahay5614]

I have solar and a Powerwall 2 (installed in 2019) and have had no issues. If we were to get a longer term power outage due to a cyclone then my understanding is that once the battery is empty we would be without any power because the inverter is separate so the home nor the batteries could be supplied by our solar panels without grid back up. Would this be different with the Powerwall 3 having a built in inverter? If so this would be a major selling point for locations such as ours.

[@GaryDoesSolar]

My understanding is that with PW2 and PW3, your solar system will continue to operate in the event of a grid outage, irrespective of whether the inverter is external or internal (in the case of PW3). See the text in this link: www.tesla.com/powerwall "When an outage occurs, Powerwall will help keep your solar system running or, if using grid power, will transition your home to stored energy instantly."

[@AndyBoneS14]

You said that the string inverter must be disabled to use micro inverters but I have read that you can use them together, 7.68kw of AC and 20kw of DC. Tricky to find official info whether this is true or not.

[@Tom-hb1no]

In the US Tesla has a special procing for some states - PW 3 plus Span Electric Panel for load management for $US 10,500. Would you recommend this combination or does PW3 have load shedding, so Span is not necessary? Span panel list price is $US 3,500 by itself. As a second question, could you use DC optimizers for each panel instead of micro inverters? If so that would seem more cost and energy efficient

[@MarkRose1337]

The Span would still be necessary, but apparently they integrate together so it can know it's on battery power.

[@nicksgarage2]

The PW3 doesn't do load shedding but supposedly the Gateway 3 will be able to do some of that. I'm in California and have a small Enphase 10 panel system and 27 panel system using a SolarEdge inverter. I'm getting two PW3s with the backup switch and they are going to remove all the other inverters, and optimizers, and connect the strings to the PW3s. I'll lose per panel monitoring but I've not had a panel failure in the past. I'll have a much simpler combined system. I have had microinverter and regular inverter failures. My solaredge inverter failed twice in 5 years. I will manage the loads during outages by just turning stuff off.

[@lennyvalentin6485]

Any idea if Powerwall 3 UPS functionality is of the online or offline type? Offline UPSes are characterized by having to engage a relay to connect their inverter to power the loads hooked up to the UPS. This is usually noticeable as a "blip" in the power supply when the switchover occurs, which may cause lights to blink, and worse, electronic devices to crash, and/or restart, and as our lives are becoming more and more digital it is inconvenient if the wifi access point, networking router, fiber gateway etc go down right when you might need to be notified that a power outage is occurring. Also, it's not good in general for a computer to suddenly lose power, as this may lead to data loss and also data storage device file system corruption and so on. Therefore online UPSes are much preferred, where the inverter is constantly engaged and re-transforming incoming power (this also helps to clean up voltage swings, AC frequency dips and so on btw.)

[@GaryDoesSolar]

Yeah, the Powerwalls are not UPS, but EPS... You could always add your own UPS in line to avoid such issues...

[@rhiantaylor3446]

I don't yet have solar PV but can now see a case for adding a battery system to make better use of power generated with tariffs such as those from Octopus. My roof shape is complex and I had thought to start with one area that would allow me to use a smaller inverter so as to stay within the 3.68kw generation limit for an installation without having to seek approval from my DNO. Clearly a Powerwall 3 could output way more than 3.68kw, irrespective of the solar PV sizing, presumably this would require me to ask permission from my DNO which may not be granted ?

@@ilit5472 So, on my channel, I don't generally talk about brand new products to market as they don't yet have any kind of track record They might look good and tick lots of boxes, but perform poorly in the market. I make an exception if those products appear to be truly ground-breaking and/or are from manufacturers with a strong quality record. Let's see how Anker fares... they could well end up being a great competitor to Tesla and other major brands!

[@NacNacMOTT]

While there is no doubt about the progress and quality, I am curious about the claim that it is a benchmark for other manufacturers. Do you have any references to support this? I have never heard it being considered the reference in the market, especially since it is still unclear if they have transitioned to LFP, a chemistry many other manufacturers have been providing for years. Personally, I don’t see why Tesla is regarded with such high expectations. There is nothing particularly unique about it. Many other brands can achieve the same kWh and kW output, and they all have to contend with DNO approval. In my view, Tesla offers a good product, but it is neither a benchmark nor unique. What will happen in 10 years when the inverter fails? Will the end user have to replace just the inverter or the entire kit?

[@GaryDoesSolar]

Good that you point this out, NacNac - the claim is my own and is based on the success of PW2 to date, and Tesla building on that success with an evolutionary product in the form of PW3, which is better than the PW2 in all respects. If there was no PW3, then PW2 sales would continue and increase, and therefore PW3 is essentially a drop-in replacement to that same success. To your comment that "Tesla offers a good product, but it is neither a benchmark nor unique", I think you've proved my point. That's only the case because Tesla defined a specification that all the other manufacturers now follow... On your final point, I would imagine that if the built-in inverter fails, that Tesla would have a swap-out programme in place to resolve.

[@hank-kal]

​@GaryDoesSolar regarding the final point, what if the built-in inverter breaks after the first 10 years and therefore the PW3 is no longer under warranty? If the PW3 is truely LFP (which I would still like to get a formal public confirmation from Tesla), it should last much longer than 10 or 15 years with at least 70% capacity. We know that most inverters (including Tesla's string inverter) lifespan is right about 10-12 years, which will turn the PW3 into a brick once it fails.

[@Phil-tv9qm]

I am looking jealously at upgrading to PW2 or PW3, but being an early adopter with a PW1, I’m stuck. It’s incompatible and there is nowhere to take/sell a secondhand PW1. Only option seems to be to stick with a PW1 or convert it into a garden table.

Does it have output to grid to be switched off or limited to 5kw? My electric company wont let me export more than 5kw. I also would like to install on my sheds and granny flat that would be independent and only pull from the grid when batteries run out. My fronius has to be connected to grid and will not operate unless it is connected to the grid. That does defeat my purpose of using the inverter. I like to use a automatic switch to switch to grid when the solar and batteries are down.

[@GaryDoesSolar]

I believe the PW3 can be instructed only to export up to a certain level, to meet energy company stipulations. Your installer will advise on that and also the other questions you raised. What's good about the Powerwall is that in a power outage, because it automatically islands itself from the gird, your solar panels can continue to generate power to run your home, with excess being stored in the battery.

I'm concerned about the Inverter being soldered to the batteries. The inverter will probably die after about 10 years or less. The batteries should last at least twice that long. Will be a waste to throw it all out once the Tesla Warranty expires and the Inverter is probably on its last legs. With a $10k+ price tag probably won't reach ROI (or will have just barely) before needing to trash the thing.

[@GaryDoesSolar]

I'm pretty sure that Tesla have a plan for that eventuality. After all, if a major component in your car fails, it normally gets replaced - you don't have to throw away your car... I'm also pretty sure that the inverter is not soldered to the batteries for that very reason.

@@GaryDoesSolar Yea, it's funny you mention the car analogy. Since a Tesla with a bad out of warranty battery is almost not worth replacing based on estimates I have seen.

When it comes to the PW3 I would love to know more about the architecture of the Inverter and its Connection to the Battery inside the unit. If the inverter were to go bad outside of warranty could they just replace the inverter? If so, how much would it cost? Might be hard to get those answers but I think they are worth asking.
