Newbie solar system voltage question and sizing
Hello, new guy here. I am building my system for a home 24 miles SW of Seligman, Az. I have 8 JA Solar panels, 280 watts, 36 volt max power voltage. Originally I was thinking of a 24 volt system but now I am not sure. I already have a Magnum 4000 watt, 24 volt inverter and a Flexmax 80 charge controller. It appears judging by Outbacks sizing tool on their website that at 24 volts I can only run 7 panels because of the wattage rating of the controller, or add another charge controller and run 4 batteries on each. Or I could sell my 24 volt inverter and buy a 48 volt inverter and have a lot more options as far as panel array. I figure my daily usage at 5200 watt hours per day at the highest. I am planning on 8 Fullriver DC400-6 batteries. I also have a 17 kw generator for backup. Any advice or thoughts would be greatly appreciated!! Also is this system sized correctly for my needs?
