5. Protection, Troubleshooting and Maintenance

5.1 Protection


PV Array Short Circuit
If a PV array short circuit occurs, clear it to resume normal operation.

Load output overload
If the load current exceeds the maximum load current rating, the controller will
disconnect the load. The greater the overload, the faster the load will be
disconnected. A small overload could take a few minutes to disconnect.
Disconnect due to overload must be cleared by pressing the setting button.

Load output short circuit
After one automatic load reconnect attempt, the fault must be cleared by pressing
the setting button.

PV reverse polarity
Correct the wiring error to resume normal operation.

Battery Reverse Polarity
Correct the wiring error to resume normal operation.

Damaged temperature sensor
If the temperature sensor is short-circuited or damaged, the controller will be
charging or discharging at the default temperature 25C.

Overheating protection
If the temperature of the controller heat sink exceeds 85C, the controller will cut-
off the input and output.

High Voltage Transients
The battery is protected against high voltage transients. In lightning prone areas,
additional external suppression is recommended.
