Figure 1-3 PV Charge Controller
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.
