Hello, I'm looking for as much info on a solar system as possible. I use about 2000 kw per month and would like to no longer rely on municipal electricity. I dont mind connecting to the grid, but I dont want to have any electric bill. I'd like recommendations on panel brands, solar controllers, backup batteries, and inverters. I am no electrician and am not interested in installing this system myself. I've seen the tesla powerwall 2, will this be a good enough backup battery, and will the built in inverter be enough or will I need another inverter. Thank you for any help!!
