I am looking for some info from existing owners who have multiple Powerwall 2s or perhaps an installer. I am aware that the max output power of a Powerwall 2 unit is 5kW. I intend to have 2 x Powerwall 2s installed, mostly to provide adequate storage capacity for my electrical needs. Can anyone tell me if I daisychain 2 x Powerwall 2s, does that give me a max output of 10kW? I am trying to work out if I can run my 6kW electric water heater at the same time as charging my Model S at 4kW without drawing grid power for example. I have 240v 3 phase power to my house (I live in Switzerland) as well as 3 phase coming from my solar panels. Will I be able to get 3 phase out of the Powerwall 2s or do they just output single phase 240v? I currently charge my car using the UMC plugged into a 3 phase plug. I run that at 5A, 400v (technically 380v I think) 3 phase giving me 4kW on the screen in the car/app. I'd love to maintain 3 phase charging but am not sure if Powerwall 2 supports it.
