Greetings. I recently purchase 6 250 watt panels to affix to my garage roof where I have no utility power. The panels specifications are:
Rated Power: 250W
Open circuit voltage (VOC): 37.6 V
Max power voltage (VMP): 30.3 V
Short circuit current (ISC): 8.85 A
Max power current: 8.27 A
The panels will have good exposure and will be used to charge a 280Ah LiFePo4 12 volt battery. I find specifications such as "12V battery systempen circuit voltage ≤48V(Voc) maximum. PV input power:1040W" a bit confusing, so I would be appreciative of recommendations for sizing the solar charge controller.
I am open to connecting the panels in a series-parallel combination.
Thanks much for the input.
