My home runs on grid-tie solar. I don't have batteries so power comes from PG&E at night. However, I would like to run a 400W 120V AC pond aerator 24/7. To run the pump "off-grid" at night, I figure I need roughly a 1000W inverter and a 100Ah battery.
My question is: Is there a solar charge controller that can run off 120V AC during the day to run the pump and charge the battery, and then be on a timer to automatically switch to the battery and inverter at night?
