Hi All, Is anyone familiar with the wiring in the old Sunny Boy U inverters? We have got a call from someone who has one where the temperature sensor has gone bad, and it is always in derating mode. It derates so much that it can only produce about .1W, even if it is cool out.
The inverter is located inside a barn, and has been cleaned. The inverter is also past warranty. Anyone have any wiring diagrams for this kind of inverter? Or any suggestions as to how to bypass the temperature sensor, or change the programming so that it does not derate anymore? Anything would be useful, as the alternative is to just get a whole new inverter. Cheers, Dave *--* *Dave Tedeyan* *Project Engineer* *Taitem Engineering, PC* 109 S.
