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.
