V.  Device parameters

   5.1  Protection function

table5- 1.Protection function reference table :
Protection functioninstruction
PV over voltage protectionWhen the PV array charging voltage exceeds the controller's rated input voltage range, charging will stop.
Battery polarity reverse connectionWhen the polarity of the battery is reversed, the controller will not work and will not be damaged. After correcting the wiring error, re-open the opportunity to continue normal operation.
Battery over discharge protectionWhen the battery voltage is lower than the set undervoltage value, the discharge of the battery will be automatically stopped to prevent the battery from being over-discharged and damaged.
Battery overload protectionWhen the controller output current is greater than the set value, the load output will be automatically stopped to prevent the battery from being over-discharged and damaged.
Battery over volatge protectionWhen the battery voltage reaches the overvoltage protection setting value, the battery will be automatically stopped to prevent the battery from being overcharged and damaged.
Night anti-reverse protectionAt night, since the battery voltage is greater than the voltage of the photovoltaic module, the automatic protection prevents the battery voltage from being discharged through the photovoltaic module;
Equipment overheat protectionThe controller has its own temperature sensor. When the temperature is higher than the set value, the charging will stop. When the temperature is lowered, it will automatically start to work.
High voltage surgeThis controller can only protect high-voltage surges with low energy. In areas with frequent lightning, it is recommended to install an external lightning arrester.
