I currently have a 5kW solar array with Enphase micro inverters on the East slope of my roof.
I would like to add 9.5 kW to my West roof slope & 2.5 kW to my South garage roof slope.
I also want to add a Powerwall to the system for backup power. My home consumes about 30 kWh’s of electricity per day even with the current 5 kW system & I plan to add a second EV in 1-2 years.
I realize the Powerwall can only handle 5000 continuous watts so I’m trying to figure out the best way to connect all of this solar.
I am curious what will happen if I connect the existing 5 kW’s of solar to the PW & backfeed the remaining 12 kW’s into my main breaker panel? What happens to the 12 kW’s of solar in this situation if the grid goes down? Does it shut down or will it try to power loads & charge the Powerwall?
Can I wire all 3 of the arrays into the Gateway & just manually disconnect certain arrays during a power outage to keep the Powerwall from receiving more than 5000 watts?
Any other ideas?
I guess the easiest & most expensive option would be to just get more Powerwalls.
