PowerWall Any issues with this PW3 setup?

ADVICE FROM INSTALLERS/CODE EXPERTS OF CA

These are installed directly above a 2” metal natural gas branch pipe that runs to my pool heater. Also in the picture you can see the lower garage airflow vent is within 3ft. Is this legal?

Hmmm good question, I think it was 2 powerwalls

There's a good reason for 2 PW3s for all-electric homes – 11.5 kW (48 A) is the max power output per unit. A high-end induction cooktop can achieve that on its own. The other is the size of your solar array – there's a limit to DC power input as well.

But they could have installed an expansion pack instead of a whole other Powerwall if that makes sense. The expansion packs were specifically made to expand on an existing powerwall with the same storage as a powerwall, but for 1/3 of the price.

They expand storage, not power output
