<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">I can also commend Kyocera's excellent customer service re: the KC120 failure issue. We had one site that involved a large crane on
a barge to access panels perched up on tracker on a rock bluff by the ocean - and they covered 100% of the costs for that, several thousand, which was clearly above and beyond warranty obligations.

<p class="MsoNormal">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 them with remanufactured units. <o:p></o:p></p>

<p class="MsoNormal">Bill, the typical failure is Voc of about 10 volts. However, the failure can be intermittent. For this reason, any modules in the date period should be replaced even though they appear to test OK.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">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 disconnect leads from terminals in PV j-box of the 'dead' PVs and I get Voc=18.5 (pretty hot day) and Isc= 6 amps. However when I reconnect these same PVs to the combiner there is no
change in combined amps. Fronts and backs of PVs look good, no burns, browns, bubbles in backsheet, under the glass looks fine, its all good. Inside the J-boxes look perfect/new.<br>
Ideas?<br>
