Is it possible that there was a lightning strike nearby, and the light flash created the high max power readings?    I'm calculating almost 1400 w/ m2, (3075/2205 x 1000 w/M2) which is high, but not insanely high.  They used to use flash testing to rate modules, so a fairly instantaneous flash

HI Bruce, OB specifies 2000 watts STC max for the FM-80 at 24v. Gotta say I've never measured 3X solar irradiance, impressive. jay peltz power > On Nov 22, 2018, at 7:37 AM, Solar wrote: > > I live in Northern MN and we get very cold days (-50F +) and very crisp clear > days when it’s

Bruce, Wrenches Your case is interesting because everything was operating and in place but the range is tighter and only has 3 modules connected per string. In Hawaii we recorded close to 3000 watts m2, during a commissioning of a 100 k Satcon inverter had 3 equal conbiners, with only one

I live in Northern MN and we get very cold days (-50F +) and very crisp clear days when it’s this cold. I’ve seen 1333 WM2 on the same plane as my array with snow reflecting sun light. Using the daystar irradiance meter. I am at 1400’ so your increased elevation with very cold temps, snow and
