5. Protection
Load Overload
If the load current exceeds the rated current of controller (≥1.05 times
rated discharge current), the controller will disconnect the load.
Overloading must be cleared, then press the switch button.
Load Short Circuit
Fully protected against load wiring short-circuit (≥2 times rated
discharge current). After one automatic load reconnect attempt, the
fault must be cleared by restarting the controller or pressing the switch
button.
PV Reverse Polarity
Full protection against PV reverse polarity, no damage to the
controller will result. Correct the wiring to resume normal operation.
Battery Reverse Polarity
Full protection against battery reverse polarity, no damage to the
controller will result. Correct the wiring to resume normal operation.
Damaged Temperature Sensor
If the temperature sensor 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 stop charging and discharging. When the temperature is below 75°C,
the controller will restart.
High Voltage Transients
Limited internal transient protection.
In lightning prone areas, additional external suppression is
recommended.
