Behavior
PV Array Short
Circuit
When PV shot circuit occurs, the controller will stop charging.
Clear it to resume normal operation
PV Overvoltage
If the PV voltage is larger than maximum input open voltage
150VDC, PV will remain disconnected and warning until the
voltage falls safely below 145V. PV voltage cannot be too high,
otherwise it may damage the controller.
PV Overcurrent
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.
PV Reverse Polarity
The controller will not operate if the PV wires are switched. Wire
them correctly to resume normal controller operation.
