5 Protections, Troubleshooting and Maintenance

5.1 Protection

PV Array Short Circuit
If PV array short circuit occurs, clear it to resume normal operation
PV Overvoltage
If PV Overvoltage occurs, the array will remain disconnected until the voltage falls
safely below the maximum rating
PV Overcurrent
If PV Overcurrent occurs, the array will be disconnected automatically
Load Overload
If the load current exceeds the maximum load current rating, the controller will
disconnect the load Overloading must be cleared up through reapply power or
pressing the setting button
Load Short Circuit
Fully protected against load wiring short-circuit After one automatic load reconnect
attempt, the fault must be cleared by reapply power or pressing the setting button
PV Reverse Polarity
Fully protection against PV reverse polarity, no damage to the controller will result
Correct the miswire to resume normal operation
Battery Reverse Polarity
Fully protection against battery reverse polarity, no damage to the controller will result
Correct the miswire to resume normal operation
Damaged Local Temperature Sensor
If the temperature sensor short-circuited or damaged, the controller will be charging or
discharging at the default temperature 25℃ to prevent the battery damaged from
overcharging or over discharged
High Voltage Transients
PV is protected against high voltage transients In lightning prone areas, additional
external suppression is recommended
