Exploring The Tesla Powerwall 2: A Detailed Look

Apologies, I think I got confused between car and home battery warranties and I’m told the Powerwall warranty is 10 years and not 8.

I wanted to add PW3s to my existing Enphase PV system with their IQ8A micro inverters and was just informed the PW3 currently doesn't work with my gear (12.5 kWh PV system about 25% more generation than consumption with NEM). So my installer suggested some Enphase 5Ps or the PW2. He did say the PW2 would be much cheaper offer more backup power and take up less wall space in my garage. So he's working up an estimate. In addition to the 30% tax credit I was informed my local utility will give me a $300 per kWh CASH REBATE, so I'd be getting $9100 back as a CASH REBATE. I can get two PWs for a few thousand less than a noise 24kW generator. So while I wanted LFP I can live with the PW2 given it will be installed inside a finished garage. Great video and you answered all my questions, especially the Phone Pairing info.

Thanks, this was very helpful information for a beginner like me.

Thankyou so much for the advice with the Powerwall 2. I just had one installed yesterday and am waiting for electrical check and switch on. Can’t wait to see how much it’s going to help with power bills.

Hi Lee. FYI, I also didn't qualify for a battery rebate, because I already received a (much smaller) rebate on my solar panels (this is in Melb BTW). However, I am a TSLA shareholder, and me being rather brazen, spoke to my Tesla liaison person to see if I could get a shareholder discount - and the answer was YES (after I proved I actually had the shares). I got $1000 off the INSTALL (not the battery itself) which is really pedantic to be honest. I didn't care where it came from, but I paid $1000 less. Happy days! Like they say, if you don't ask, you don't get. Regards, Greg.

The Tesla Powerwall has been great. We have had one for 5 years and added a second unit a couple of years ago. Best savings for us on a time of use tariff and a virtual power grid agreement. Battery warranty is 10 years. We had a grid outage for 10 hours during daylight and charged our car, ran the house as normal and kept the batteries full until power returned. The whole system should pay back when including solar plus battery plus electric car.

Thanks for the great review! You've convinced me to get one 😂

Thanks Lee. Very useful! Will fwd this to the wife and hopefully convinced her down the track lol.

Grid charging is only about the battery. When turned on it can pull power from the grid to recharge the battery either to replenish your backup percentage or in time based control mode it can use grid power when it's cheap if it doesn't think there'll be enough solar to charge and get through a peak pricing period. With grid charging off, the battery will only charge from solar. Your house can still use grid power when you get to your backup reserve or when time based control thinks the grid is the more advantageous option.

Why get a Powerwall ? Two reasons mainly, firstly, whole home backup if there is power failure (and I have a lot). The second reason is environmental, meaning, when the sun goes down, the powerwall kicks in, it replaces all the peak (read expensive) grid power that used to come in to power the house (all night). No power coming in means no pollution is happening thanks to me / Powerwall. As for finances, I seriously doubt I will ever recoup all of the costs, but that's not why I got it. Hi Lee. With regards to the 2 days of clouds, I monitor the wholesale price, and recharge from the grid at the lowest possible price if necessary. But, even with the clouds, power is still being generated by my solar, further reducing what I may get from the grid. So far this year April 2024, I have used $4.76, but exported way more than that (at super peak rates)...

Great video, very informative. One question: Do you have a standing charge from the electric supplier even if you don't use any electric. Thanks

Thanks for the insight. The Powerwall settings part of the Tesla App is still a little confusing. Not sure how to interpret Virginia Dominion’s power bill for the Tesla App settings.

25:14 10 years with 70% capacity if used normally. 38MWh or 10 years if used for other ways (eg. VPP, etc)

Lovely video mate, Did I hear right when you said something about Enphase microinverters. Do they work with Tesla powerwall and what are the issues you may have?

Great video i could never find out why i needed to pair my phone for off grid that was very clear , Thanks . The problem i have in the UK is when i try to add my none Tesla car and electric billing it's all for the US its asking for my State and Zip code so i cant get passed that . How did you set it for Australia ?

Interesting video. I'll wait till they are cheaper. On another note, have you noticed the mobile connecter is now charging the full 10 amp with the 10 amp tail? Rather than only 8 amp. For about a week now.

Interesting 👍. We have had SolarEdge Solar Battery for the past 12 months . No blackouts in our area yet. However no power bills either just $400 credit. We recently switched to Amber Electric (wholesale ⚡️). This seems to work well🔋. Have you considered switching to Amber?

Does anyone know if Tesla increased the maximum output power of the Powerwall 2? I had one installed last month, and the electrician thought the output had been increased to 6kW continuously in the latest firmware update. I've seen it suggested on some websites that Tesla did increase it, with Wiki saying "Powerwall 2 shipped after November 2020, had the same capacity, but can deliver 5.8 kW of power continuously and up to 10 kW of peak power." But I can't find this anywhere on Tesla's website, all their documents still say 5kW with 7kW peak.

15:00 I must live on the edge. I have it set to 0% and regularly during winter drain it too 0 🤣

Hi sir i am living in abu Dhabi I am from Pakistan i want tesla powerwall 2 so how can I get please help me thank you
