I’m planning 4 x 305w panels, specs
VOC 39.9
VMP 32.3
ISC. 9.76
In series, that’s 159.6v/9.76A
Series/parallel gives 79.8V/19.52A
I assume the 100/50 would work as minimum, and the 150/45 would work and offer a little expansion.
My confusion is the 79.8V X 19.52A = 1557 watts, which is over the allowed watts for each unit.
I assume you use VOC for one calculation, and VMP for another. Will either unit work as I’ve described?
