Hi,
Haven't found the information anywhere, then I thought I would ask ...
Got some remaining space on a roof for 3 panels. Those 3 panels would have a total VOC < MPPT startup voltage, then I can not connect them directly to my inverter.
1. I could build a series string with them with other exact same panels but there is a distance of 10ft / 3 meters between the 2 sets of panels. Is that distance reasonable enough or would create too much of a voltage drop between panels of a same string ?
2. All panels are fitted with 12 AWG / 4mm2 cable from their junction box, could fit a thicker cable between the 2 sets of panels to limit the too much voltage drop if any ?
Thanks for your advices
