* 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.

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 Месяц назад

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

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.

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 Месяц назад

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 Месяц назад

@@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.

@@HecticGlenn that costs me £7500 + DNO fee. With the help of chatgpt, I estimate the breakeven point at 6.5 years. My average consumption is around 8-9kwh per day. 😉

@whattheschmidt 10 дней назад

The reason I would want more than 13.5kwh of storage is when I want to offset a lot more production to my own use - for more financial gain there. In a few years I will only get half of the money for energy I export to the grid vs paying to get energy. My best days generate 50kWh or more, so using say 20kwh easily from 4pm-2am would be great on those hot sunny days. I'm in the US by the way. I'll keep watching this, but PW3 seems like a winner and DC coupling another may make sense for me.

@TheTobster79 Месяц назад

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 Месяц назад

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 Месяц назад

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

@JunYamog Месяц назад

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 Месяц назад

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 22 дня назад

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?

@DUNCK14 Месяц назад

Considered waiting a year to see if price comes down, but on Intelligent Octopus Go I'm keen to get the savings this winter running the home on 7p pkwh.

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 .

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.

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.

@smartLooser Месяц назад

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.

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.

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 28 дней назад

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.

@SteveLoughran 20 дней назад

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

@NacNacMOTT Месяц назад

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 Месяц назад

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 Месяц назад

@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.

@robsengahay5614 29 дней назад

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 28 дней назад

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."

@cottawalla 20 дней назад

If we assume the installation cost is £750, a PW3 then costs £7000. At 37.8 MWh total throughout (warranty spec) that's £0.19 per kWh plus the amortised cost of the PV array used to charge the battery, let's say £0.29 all up. How does that compete with grid kWh charges?

@GaryDoesSolar 19 дней назад

@lennyvalentin6485 Месяц назад

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.)
