> How much is your power bill in summer? Must be $300+, going on 500 during the hottest months? At that rate, you'll make back the $20k + $10k that 10k Wp + 2 of these batteries would cost you in what, 5 to 7 years?
No, here in Houston we've got "deregulated" power in a completely reasonable way. One company owns the lines and handles recording the meters. They charge about $0.015/kWh for this. Then there are about 100 companies that offer electricity in a multitude of different ways. I'm paying $0.08/kWh delivered to my "door" so my worst months are only $150 or so.
Your idea is a nice one, except that I would need more panels and at least 2x the batteries/inverters. If I need 3kW CONSTANT to run the AC then 3kW PEAK doesn't do me any good.
> but that doesn't take away from the fact that with one extra of these units + 10k Wp of solar panels, you could power your AC's with power to spare to be stored in the battery pack
Not really. Look I know Tesla is awesome, and solar is awesome. I'm interested in both. But the economics really aren't here yet in Houston because of how cheap power is, because there's not a state owned utility screwing us bigtime. Houston has a lot of problems to be sure but power prices aren't one of them.

tl;dr Houston isn't California.
