Protections
Protection Behavior
When PV shot circuit occurs, the controller will stop charging.
Clear it to resume normal operation
If the PV voltage is larger than maximum input open voltage
150VDC, PV will remain disconnected until the voltage drops
below 150VDC.
The controller will limit the battery charging current to the
maximum battery current rating. Therefore, an over-sized solar
array will not operate at peak power.
The controller will not operate if the PV wires are switched. Wire
them correctly to resume normal controller operation.
If the temperature of the controller heat sink exceeds 65, the
controller will automatically start the reducing the charging
current and shut down when temperature exceeds 80
The controller will not operate if the battery wires are switched.
Wire them correctly to resume normal controller operation.
