<p>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 can do it.<br>

<div>Compadres,</div>
<div><br>
</div>
<div>I have 4 identical arrays of 3 strings of 3 Solarworld SW
245 mono (2010 model) to FM80s. When designing, not exceeding
150 voc was critical. No record temp data available. Location
~ 4,000' Pacific Northwest. Recently replaced an FM80 with 6
blown FETs showing max power at 3075 watts! This from a 2205
watt array into a 24 volt battery. Max historical voc is ~120.
My guess at record low temp is -10F. tc%/ēC MPP doesn't get
anywhere close. What would the WM2 need to be in order to
achieve 3075 watts on a 2205 watt array? BTW, 2 of the four
original chargers are still working fine and one of them also
shows 3075 watts max power. Edge of cloud effect against snow
field at bottom of array?</div>
