Been wondering...
With home batteries, think of the Tesla powerwall, does anyone know what the operating voltage of the battery is? I'm guessing but I'd think the solar panels would come into the battery at around 300-400 Vdc. When power is demanded from the battery, the power from the cells has to be inverted. Does anyone know what the inversion voltage is? I can't see it being a 48Vdc inverter.

I am told but someone in the know that the Power Wall + internal battery voltage is actually 48V
Surprised me. I would LOVE to see a teardown of that to verify !

I saw a video on the 'ol YouTube about a tear down of one.

Not enough detail to be absolutely certain but it does appear to be a 48ish volt system.

Yes, I saw that one a while back.
But I don't think there was an inverter in that battery pack. Just a BMS ? This may have been a powerwall battery only that was supposed to be used with one of the approved inverters like the Solar Edge ?
The one I want to see inside is the newer Powerwall Plus I think it is called ?
