Tesla Powerwall 3 Home Battery Review

This is a great video! Thanks for putting this information out. I am ready to install solar and having well presented information like this is so helpful!

The "dude trust me it is LFP" IS strange. One can speculate that they want the freedom to use different batteries based on what is available and cost-effective and that they have designed the electronics to be flexible and to work with a few different options. LFP is a selling point in itself, but one can speculate that they don't want to hint that their previous house batteries are bad or unsafe. And they don't seem to be. The news would be full of it if Tesla Powerwalls were exploding in people's houses. Anyway, I trust the "dude" here. Seems to know his stuff, and has a good beard. All good. 😁

Thank you! Very helpful and easy to understand. Love the Pro and Cons explanation and examples given. 👍👍👍

This is by a huge margin, the best explanation I have seen on how Powerwalls, and in particular, the powerwall 3 works. I can't tell you how many 20 minute videos on YouTube I've come across that tell me nothing more than the bold text on the Tesla website - which only takes 5 minutes to read. I really hope my installer is as well informed as you. On my next phone call, I'll now have lots of intelligent questions for him. FYI - installing Solar in CA is just plain awful. Powewalls need to be spaced 3 feet from any door or window, 3 feet from a gas line, and here's the killer - 3 feet from each other. You need a pretty big, windowless house to install more than one or two Powerwalls. The utility only buys back at 7 cents per kwh. But charges 60 cents peak, and 24 cents off peak. You basically need to be 100% grid independent.

Looks like a great battery and it comes with a 6 string inverter! I was thinking of getting micro inverters for our apartment but if I can save money and still have just the battery and a gateway in the garage then I'm happy. Good to see they have rapid shut downs.

well done, I've heard many of the new solar panels have the ability to get shaded and not hurt the rest of the string, even without optimizers or inverters.

Optimizers could be used in conjunction with the Powerwall 3 correct? That is no different from when solar PV with optimizers sent DC to a standalone inverter and from there to a battery (if you had one). Thanks for the details and the clrificaion on LFP batteries. Looking forward to some future videos of installations with the Gateway 3. We don't have the same meters here in the UK, so it would be Gateway3. Good video, thanks.

Awesome video! Clears up qiestions after your BG3 video. And many ither questions. Like and subscribe! Only thing missing was VTH and VTG, VTX. Hoping this is all included at some point. Have Cybertruck soon which includes paid for 3V gateway. There are enormous advantages to having PW3 in system. 3V gateway will be PW3 compatible at some point, but not now. Tesla said that I could do 3V gateway now, but would require special support for commisioning to disable 3V site controller. They recommend I instal BG2/3 or Backup Switch instead. Any thoughts about which gateway to go with? Mostly concearned about future compatability with VTH and VTG.

when the dc expansion packs come out, is it possible to add just that to enphase panel system ? or do we need the pw3 and the dc pack can only be added to an existing pw3 ?

Thank you for sharing all this information. You show the PW3 landing on the LC. But doesn't that require a derating of the main LC breaker for that much backfeed on the bus? And if you have multiple PW's, the backfeed current gets crazy fast. Shouldn't those land on the GW3 to control the total current on the LC bus? I rarely hear about the desire to NOT derate the main breaker. And second question: Just what is this mysterious "remote meter?"

Tesla Energy! 😍

Adding 2 PW3 to my existing Enphase PV system. Would not give up my individual panel monitoring. But the PW3 is a lot of bang for the buck. Installed after all credits and utility rebates OTD for $19K. My second PW3 is the Expansion unit. I'll have the best of both worlds.

How about an install on a house that already has solar but no storage? Is there a way to install a PW3 so it charges off excess solar during the day and runs the house in the evening/night, without tying into the current solar system?

If you have an EV can PW3 charge it DC without inversion? Straight from the panels or battery?

This may sound like a strange question, but if I get a Powerwall 3, do I no longer need a whole house surge protector like an Intermatic? IOW does the Tesla gateway handle surges from the grid or will an additional whole house surge protector be beneficial? I live in central Texas and and we're getting some weird blackouts , brownouts...and surges where some breakers get flipped.

Can the pw3 be an off grid system?

Can I add a Tesla Power wall 3 to a tesla powerwall 2 so I can sell more on the Virtual power wall?

Do you install systems in Johnson City Tn?

17:00 The Tesla backup switch, eliminates relocating loads to a Backup Load Center. If there’s not enough space in the main panel for the PW3 breaker a generation load center might be needed. 20:05 The PW3 can work with a Generac backup. Main panel, Gateway, Generac breaker in Gateway, then Generac relay, then Backup Load Center.

How much energy (in kilowatt hours) can the power wall 3 actually store?
