I am setting up an off grid solar home and think using two mpp solar lvx6058s to provide 120/240 power seems like a good approach. I would like to have a back up generator for times when sun is sub-optimal. The mpp site suggests using inverter generators as the power is cleaner. I am thinking that I need a fairly large generator (5000-10000 watt) as system will be large with solar array of 10-15kw and battery capacity 20-30kwh. Is my tHinking correct? Can anyone suggest compatible generators for these 6058s?
