I have these panels:
My two EG4 6500ex inverters will take 4 strings of panels in series and has a max PV input of 4000 watts per string. Max VOC is 500 volts per string.
I'm wanting to connect 8 panels on a single string. Those calculations are:
460 watts per panel * 8 panels = 3680 watts
50.8 VOC * 8 Panels = 406.4 VOC
By those numbers I should be good. My question is on the bifacial gain (they will be on a pergola on a deck), which can spike up to 575 watts.
575 * 8 = 4600 watts.
At that point I am over the max wattage. Is this a safe amount of over-paneling, or should I limit the string to 6 panels?
