Still one of the best investments I’ve ever made. Just wish that I had gotten more than 2 of them. At least charge on solar helps mitigate some of the ‘issues’ caused by overproduction. I’d rather dump extra generated power into our cars than export it back to the grid.

I work for Sunrun (nation’s largest installer of residential powerwalls). Everyone of my customers love their batteries 🔋

same, im debating if i should get another tesla since its basically same cost as a powerwall... Ecoflow setups are also looking super attractive too

That doesn’t seem like very many

PW3 is amazing here in CA with NEM3 and if you can get incentives for it, its an absolute no brainer. Its already saved me from several outages as well. Getting a 2nd one installed soon.

More than twelve.

Yeah, and why are they still more expensive per kWh than whole cars that include a battery?

10k Euros for 13.5 kWh in Germany is too expansive. At least in my humble opinion they could do more for the price

Yeah this is the insane part. I figured a $10k unit would be like 50kwh, not a fraction

The idea of generating your own power via solar and being insulated from the grid is so appealing. Just need to get a house first...

Everyone wants a second one but this is the reality. I’ll wait until this happens otherwise cost to benefit ratio not worth. Otherwise having a PW3 is awesome.

they can, they’re charging like 60k for 4 powerwalls.

It's a lot. Tesla has sold 8 million cars and you see them everywhere. There's a Powerwall owner for every 1 in 8 of these that you see, which is still a lot.

I have 325A service to my house. At 240v (north america) that's 78kW potentially. How many power walls is suggested to cover that? It's actually a 200A service and a 125A service, wired separately in the house. It's weird. But I figure installing batteries and solar panels, change up the wiring. The actual loads are significant, though. It's an all electric house. 60A HVAC, another 60A HVAC, 30A blower, another 30A blower, 30A oven/range, 30A water heater, 30A dryer, couple dozen 20A circuits, and a 50A EV circuit. If the power is out, which is why I'd be installing any of this, really, I don't care about running any of the big loads. So the powerwall inverters just need to be able to run the fridge, lights, microwave, and a pile of electronics. Probably less than 1 powerwall's output. If I don't want to draw from the grid and still run all my systems, what's required?

Start small.. get a tent!

Small correction: It's 13.5 kWh not 10.

Thanks, for the info. Change my original comment :)

I've paid 10k for 16kWh with 20kW inverter, installation and paperwork

You would need to meet with a solar company or battery installer. Your draws are not nearly as high as your breaker amount. I have the older Power Wall 2 which put out 10kW and my house runs like normal when the power is out. I just don't run the dryer or hot tub as that would put me over the limit. New Powerwall setup PW3 would get you 26kW which is probably plenty but the installers can give much better estimates than anyone on here as they can look at your bills and current draw to devise a plan.

So 1M people who've paid too much for something they can get elsewhere for less

In terms of home batteries PW2/3 best options.

I think powerwall was a game changer, but now there are so many great 48v options on the market for 1/2 or 1/4th the price per KWh, Tesla needs to catchup.

Installation is easy. It's working with city permits that make it more expensive. Some cities have codes that state that an Electrical Storage System has to be on a wall 2 Feet from any windows, doors, or any utilities. Cannot be installed on a wall opposite of a bedroom. If Installed inside the garage, a fire alarm system and water sprinklers must be installed. Like I kinda get it, but also I could see electric companies making more rules because they'll make less money.

That's the battery only, you need additional DC/AC inverter

Once you see any high capacity battery set ablaze, or any high capacity transformer or inverter have a catastrophic failure, you know why those regulations are in place.

Agreed. It's so much cheaper to buy a whole car that something like [https://www.sigenergy.com/en/products/dc-charger](https://www.sigenergy.com/en/products/dc-charger) plus a used Tesla becomes a competitive option. I'm curious to see reviews/tests of it, but it's basically a home DC fast charger that can also do vehicle-to-home even with Teslas that don't support it out-of-the-box.
