Hi, all!
I got some fairly strange numbers today that I would like to have some feedback on. Is it possible to get ~725W input from two REC 405W rated panels (two in series currently for 810W nominal) in February in Pennsylvania? That works out to be 88% of the rated capacity, and I find the entirely suspect. Just the day before under similar weather conditions, I saw a consistent peak of about 520W, or ~62% of the nominal rating of the panels. These are nearly flat mounted on the roof of my travel trailer, and not pointed in the best orientation, and even have a partial occlusion due to a roof peak near noon.
The 520W seems at least possible and matches well with the JK BMS and shunt readings at the time. I don't have logging via the shunt yet, and I was at work while these very high peaks happened, so I don't have any corroboration from other sources that this is actually what was happening.
Here are the crappy screen shots of crappy WatchPower for most of the day:
SO is that plausible or is it just junk data from watchpower or the 3048 itself?
