Hi... So we recently built a large house and have an EV, and currently on the PGE EV-A tariff. We have a lot of solar, but have a 400 Amp feed, and a generator for backup power. I understand generators are not supported with powerwalls, and Tesla doesn't have gateways for 400A feeds. We looked at Powerwalls for power backup in an outage, but felt the generator approach was a much better choice.
I'm now thinking about using powerwalls purely for load shifting, trying to figure out if the economics were to pan out. We have a 26 KW solar system, and generates more than 120 KWh a day (during the spring and summer). The primary goal would be to minimize any energy use during peak hour, and push any extra energy generated during the day back to the grid during peak pricing.
We have a 400A feed and a genset, so a traditional install will be problematic. If I just connected the gateway to the main panel ahead of the generator transfer switch, with nothing behind behind the gateway except the powerwalls, would this work for load shifting with the Tesla software configurations allowed?
thx
