I will be building a house this coming spring.
All of our utilities will be electric (geothermal HVAC, heat pump water heater, etc).
My intention is to use a Tesla Solar Roof and 3-4 powerwalls as backup.
When the grid is online, I'd like to run off batteries from 2-6pm (peak pricing). Ideally, perfect world, they'd recharge off the grid form 12-6am (off peak pricing), and any solar I generate would either be sold to the grid or used.
When the grid is offline, obviously the batteries/solar would power everything. In an extended, low sun period (very possible in PA), I'd like to have two levels of backup:
1) a generator input, from my old 7kw propane generator TO RECHARGE THE BATTERIES (not power the house-- so I can run the generator at the most efficient load and just drain the propane tank into the battery bank.
2) reverse charging off a non Tesla EV.
... How much of what I'm hoping ot do will be possible with the Tesla solar roof/powerwalls?
Thanks!
