A few more questions:
Can you attach the spec sheet? Does it show curves at different irradiances?
What was the time of day (or was it just cloudy?).
How are you measuring the cell temp?

I see your question now a bit more clearly. As usual it brings up a new
one. How low is the winter temp for location? Off the cuff I would use
the manufacture data and it is good because it is higher than you measured
at 23C. Any guidance from panel manufacturer who is?

Hey Jay and Brian,

Hey Jason, IEC 62446-1 allows for:
Testing Voc of a single module and using that to calc the target string
voltage
and
"For systems with multiple identical strings and where there is stable
irradiance conditions, voltages between strings can be compared"
Regardless, it would be interesting to hav
I would recommend testing the temp gun against other sensors like a
thermocouple and the DAS if it’s available.

Hi All,
Does anyone know if any manufacturer is currently responsible for warranty
issues of 2013 Aurora PVI 4.2-OUTD-S-US inverters?
I don't remember if this is an "ungrounded" inverter, but in any case, if
it needs replacement, what are the code rules for replacing it with a
different inverter? I
Hi Howie
ABB (now Fimer)
1-877-261-1374.
They typically require specific photos for warranty.
Error code 031 is common.
Junk arc fault detector that require upgrade also common.
Thanks

Hey Brian,
Following up on both sets of questions:
Can you attach the spec sheet? Does it show curves at different irradiances? —

What was the time of day (or was it just cloudy?). — ~11:00am
How are you measuring the cell temp? — Fluke Temp gun (new battery)
