I have 6 panels rated at 255 watts- MPP voltage 30.0, & MPPcurrent 8.50, open circuit voltage 37.2, short circuit current 8.85, and efficiency of 15.8%; The Batteries I have are 4 Interstate L-16HCL 6 volt 420 AH, 250 mins @ 75 a . I am hoping to provide some supplemental power supply for my home and possibly emergency power in case of grid down. what advise would you offer? I'm expecting Pure signe wave inverter of about 5000 watts and a 60 amp MPPT charge controller. [ not sure about 24v battery configuration or 48 v and buy 4 more batteries ] I also have 2 - 12 volt deep cycle marine batteries if they could be a part of this brainstorm. I seem to be confused about the array voltage to choose with these components. What do you advise? I have about 90 ft between batteries and solar panels.
