anyone seen this before? low DC voltage while the sun is out
had 2 days in a row one lasted until 2pm this one was only 11:30
winter and frosty.
Just wondering if its frost/ice on the panels (one string facing west one north) but both seems to start up at the same time making me wonder. the north should be going before the west if that was the case.
anyone got any ideas? my parents system isn’t having the issue about 2km away
