Short Circuit and Reverse Connected Protection (Solar Panel)

When the solar panels have short circuit or reverse connection, the controller will be off the charging immediately, after clearing of the short circuit, the charging will be automatically feedback.

Reverse Connection of battery Protection

If the batter reverse connection, the controller will not destroy, corrected the connection the controller will be normally working.

Battery Over Voltage Protection

When the voltage of battery was more than 16.5V, the controller will be auto closed charging and output. So that decrease the destroy of the battery and loads.

Battery Low Voltage Protection (LVD)

When the voltage of battery was reach to LVD (Low Voltage Disconnection) point, the controller will be auto closed the output in order to avoid over-discharge the battery.

 

Overload Protection

If the current of load is more than 1.1times rated current of controller, the controller will be cut off the output after 60s and lock. Users have to decrease loads and press“”unlock, or 30s later the controller will auto restart unlock.

Load Short Circuit Protection

When the current of load more than 2times of rated current, the controller will be confirm short circuit, the controller will be auto cut off the output and lock. Users have to clearing the short circuit and press“”unlock, or 30s later the controller will auto restart unlock

Over Temperature Protection

When the inside temperature of controller was more than 75℃, the controller will be off the charging and discharging, temperature symbol and warning flash, when the temperature get down to 65℃, the controller auto feedback.

Lightning Protection

This product could only protect small lightning induction, we suggest users to use lightning rod at frequency area
