Hey all,
I have one MPP LV6548, currently with a string of 4x450w (50.5 Voc) panels in series. It is a very sunny day here, no cloud cover, but I am barely getting any input power. At the moment I am getting 184.6 V, but only 23 W of PV power and current is only sitting at 0.1 A.
I have tried switching between PV1 and PV2 inputs on the inverter, hoping that would isolate the problem, but getting similar readings. When I power cycle the invert, I do get 3-4 seconds of 600+ watts input, but then immediately drops back down to the 20-30 watts range. For some context, yesterday, which was very cloudy and overcast, I was also getting readings similar to today. I chalked those numbers up to cloud cover, but realizing today is as sunny as could be, my panels are at an appropriate angle for my lat/lon, and no shading at all, I would expect to see some more substantial power out of a "1800 watt" array.
I feel as if I'm doing something wrong in my setup, but not sure what. Any help would be greatly appreciated!
