Re: Inverter/Converter help?

Running the microwave, Keurig or other high wattage appliance from the battery bank would be the reason for wanting a 3kW inverter. 2kW will handle those items easily and save you a few bucks. If you're not planning on running anything like that, a 300W inverter will run most anything. Two 6V's is light for a 2kW inverter let alone a 3kW. Most here have four 6V's minimum.
