xantrex XW6048 FE1 (W57) FE2 (W58) warnings - over temperature
My xantrex XW6048 has been working correctly for a few years now. Yesterday I received the warning messages FE1 (W57) FE2 (W58) warnings - over temperature, ambient temp was 60f in the garage where the inverter is and there was no load on the inverter. The unit was continuing to sell to the grid and otherwise acting normally.
Removed the front panels but failed to take a temp reading initially. When I finally put a spot meter on the upper left capacitor, the temperature was 104f - the manual says the sensors will activate the warning when the temp is above 85c. 85c/185f is huge and a bit confounding. A few minutes later I put an external fan on the unit and within a minute, the warning disappeared. This all happened within a period of 5 minutes or so.
Could the manual be wrong and it should possibility read 85f? That would coincide with my 104f reading.
In any case, since both FE1 and FE2 were over temp, according to the warnings, and the voltage was at 244, it seems that the culprit is the fan (I could be a heat sync, but not both at the same time). However, the fan is not visible - anyone know where it is or have any experience here?
