Just got this thread. Mac and Larry are correct. As an old timer, this one
example of great customer support (specifically understanding that installing
dealers are their true customers) has given me cause to respect Kyocera and
sell and approve them to my customer base.
Allan Sindelar,
The dates of the defective KC-120-1 (and KC-80-1) are from late 1998 to Dec.
2002. Any modules in the date period will be replaced at no cost by Kyocera.
Talk about amazing commitment to the customer, these modules only had a 1 year
defect warranty. 15 years later and they are still replacing
I have this same situation with my off grid well, I have a grundfos sqf5-2
and the yield wound up being .25 gpm. Originally I ran it on 2- Astronergy
235 and made a timing system using a sprinkler timer and a midnite kid
controller it was tough to control the production as the power varied and
Kyocera had a batch of 120s and 85s that had bad solder connections from a
certain year. I'm not remembering the year at the moment but we are still
finding them.
Kyocera has been really amazing about honoring the warranty.

Have you tried shorting the strings individually?
Otherwise short each module individually and record the current.

I just came upon a small off-grid system: 12 volt, 4, Kyo 120's (I,mppt=
7.1A; Voc = 21.7 or so), Trace C40 with display, etc. The combiner has
fuses for each PV/landing. At noon, output of the array is 10.5 amps.
Clamping the 4 pvs I get 5.5 amps on 2 PVs and 0.0 on 2 others. I
