Some customers may attempt to obtain more output by oversizing the array, since the manual states it can tolerate up to 85A before tripping due to overcurrent.
However, the controller will reduce output in an attempt to prevent overtemperature, as outlined on pg.7 of the manual :
If the PV array’s output increases above the rated amp level
due to reflection or “edge of cloud effect,” the controller will
continue to operate until the heatsink reaches a maximum
safe operating temperature. This will take several minutes to
occur, depending upon the ambient temperature involved.
When the heatsink reaches the maximum safe temperature,
the controller will reduce the current, cooling the transistors
and the heatsink.
