Hey guys I have a 48V system with 2 strings of six 240W panels for a total of 2880W potential. Obviously I'm not going to get that but I find I am only getting on average 1.2-1.4 kW at max sunlight. FYI the panels are on a skoolie parked next to a wall of trees so it takes til about 1-2P before unobstructed light hits the panels. I disconnected each string one at a time from my combiner box and found there was about a 40 watt difference between the two strings going to my inverter and my understanding is if a panel in a series is dead I shouldn't get any power past that connection but my memory is a little fuzzy on that. In any event I'm faced with disconnecting in turn each panel in a series of six one at a time and checking each with my voltmeter unless someone can offer a better idea. Any constructive ideas are welcome.
