If they do begin to trip, you can go to 20 amp berakers, IF YOU have 12 gauge wire coming into the breakers. I am glad it is working well for you!

I plan on going full Solar with wind back up on the land we just bought. I love your 48 volt system voltage! I will be forced to use 24 volts (at least I avoided the 12 volt quagmire, LOL) and I have the gear here already, except the batteries. Those are coming together ( I am collecting the cells to build them) with a goal of 21,000 watts or 875 amps at 24 volts .

My wife can't tolerate the heat or cold (she has MS) so I found two minisplit heatpump systems to use in the house They use 900 watts each, and are 12,000 BTU units that will do about 700 square feet apiece. I am currently grid tied there, so I will either remove the meter, or sell power back to them.
