Hi Wrenches,
Thanks for all your input. I took the advice of those wrenchers suggesting I
had bad modules and am in the process of dealing with Kyocera - will update
when I have received their final answer.
My problem was that when I tested the modules they showed normal Voc and Isc.
But I
Eric,
Did you check the dates on the label and compare to the dates I gave you? If
they are in that period, don't wast any time, get the warranty process going.
The ones in the date range that have failed will show about 10 volts open
circuit. Sometimes one will show 21 Voc but on short
Sorry. I have to re-post this as my local, small-town email provider's server
crashed the day I sent this out. I couldn't receive any responses.
Hi Wrenches,
I inherited an off-grid PV system that seems to be significantly under
producing. I have:
12 KC120's (~19V 7A each) paired up 2 in
If you suspect the batteries are floating high and not taking charge, why
don't you load up the inverter and see how much power you are getting from
the PV system when there the inverter is fully loaded? If the PV output
loads up nicely, then your batteries are gone.

Hi Wrenches,
I inherited an off-grid PV system that seems to be significantly under
producing. I have:
12 KC120's (~17V 7A each) paired up 2 in series, for 6 strings terminated
on new 15A breakers in a new Midnite combiner,
Output of combiner passes through a 60A breaker then into a SolarBoost
Hi Eric,
Try putting the SolarBoost 50 into EQ. This will bypass the current
limitations and you will see full amps.
If no change, then try with 1 string at a time.
If still the same then bypass the controller and test with your clamp on.
This will tell you if its the array or the SB50
Good

Hi Eric,
Check the dates on the KC-120 module label. If any were manufactured between
January 1999 and December 2002, they have or will fail. We have been replacing
these modules for over 8 years now. There was a defective solder joint during
manufacture. Kyocera will still replace them under
Network from Sprint!
