I am looking to setup a small off-grid solar setup to power my 1HP Pool Pump. I would like to have the ability to switch between grid power and solar power if I need to run the pool pump. I am thinking 4 x 320W Renogy Panels, Renogy Rover 20AMP MPPT Converter, Renogy 2000W Inverter 12V to 120V AC and a battery for startup of the pool pump. Do I need a larger inverter or will this one work for the 1280 Watts from the panels and draw from the pool pump? Any and all input is appreciated.
