Our friends have 4 216 Ah batteries and still need to run the gen set for 5 hours every day. Based on the amp draw I measured that is pretty close to what Onan comes up with based on their example. The refrig draw via the inverter was ~ 17 amps. When the gen set was running the inverter/charger was putting out 60 amps. 60 amps would be about 720 watts of solar. Their 432 Ah battery bank would require a minimum of 500 watts of solar.
