I can get 255w Trina Solar panels from a local reseller/scraper for $90.
Spec sheet is here, but I think the import piece is IMPP of 8.36A and ISC of 8.92A
My charge controller is an EPEver Tracer4210AN which is rated for 40 amps and, more specifically a Max PV Input of 1040 watts @ 24v
Battery banks consists of an Overkill Solar 8s BMS attached to 8 REPT 280AH cells. So overall I'll have 280AH @ 24v available.
My load will be run 24/7/365 (if possible) and is about 200 watts at 12 volts. Max C is ~8.5 amps.
The plan is to put all four of these panels in parallel (thus giving ~35A to the charge controller).
My question:
when purchasing MC4 connectors, I'll ultimately need something rated for 35 or 40amps, right?
Because the first connector will be outputting ~17 amps, and the second connector 17 + 8.5 ~= 25.5 amps. The third would be 35 amps. Right?
Another question/theory:
Due to building location, trees, etc I'd like to put two panels facing S-SE (to be most effective in morning and early afternoon) and two panels facing S-SW (most effective in late afternoon and early evening). Any issues in doing something like that? Would I be losing power overall due to the 'less-optimal' set of panels not pushing as many amps as the 'more-optimal' panels? My understanding is that, in parellel, amps are additive.
