Five Trouble Remove and System Maintenance

5.1  Protection Function

5-1 Refer to the table:

Protection	Explain
Reverse polarity connection of solar panel modules	When the polarity of solar panel  modules is reversed, the controller will not be charged and will not be damaged. After correcting the wiring errors, the controller will continue to work normally
PV over voltage protection	When solar panel  array charging voltage exceeds the controller's rated input voltage range, it will stop charging
Reverse polarity of battery	When polarity of the battery is reversed, the controller will not work and will not be damaged
Battery over discharge protection	When battery voltage is lower than the set under voltage value, the battery will automatically stop the discharge, prevent the battery from excessive discharge and damage
Battery overvoltage protection	When battery voltage reaches the set value of over voltage protection, it will automatically stop charging the battery to prevent the battery from overcharging and damage
Night protection	At night, as the battery voltage is larger than the solar panel module voltage, automatic protection prevents the battery voltage from discharging through the solar panel module
Equipment overheating protection	There is a temperature sensor inside the controller. When the temperature is higher than the set value, the charging will stop, and the temperature will automatically start and continue to work
High voltage surge	This controller can only protect high-voltage surges with low energy. In areas with frequent lightning, it is recommended to install external lightning arrester

5.2 Trouble Remove

If the following failure phenomenon occurs, please follow the following methods for inspection and troubleshooting:
5-2 Troubleshooting list                           

Error	Indicator status and alarm icon	Possible reasons	Solutions
Array over voltage	Red light, Icon flash	number of photovoltaic array series groups is relatively large	Disconnect the photovoltaic array, reduce the number of photovoltaic array groups in series, and ensure that the open circuit voltage of the photovoltaic array does not exceed the set value in the "photovoltaic electrical parameters" table
Battery over voltage	Red light,OVD and Icon flash	1.Overvoltage protection point of the controller is lower than the maximum value of the charging range; 2.Aging or over-discharge of battery;3. Battery overdischarge; 4.Large dynamic change of load	1. Reset the overvoltage protection point of the battery by pressing the key of the device or PC upper computer or APP; 2. Aging battery needs to be replaced; 3. Overdischarge requires manual setting of battery voltage level; 4. Reduce large dynamic changes of load;
Battery undervoltage	Under and icon flash	battery voltage value is lower than the set value of undervoltage protection	1. Reduce or disconnect the load. If the alarm is cancelled, the battery voltage returns to normal, indicating that the load power is too large or the battery voltage and capacity are too low. 2. When the load controller is disconnected, it still gives an alarm. The battery voltage has not recovered to the set value of overdischarge recovery.
	indicator light does not shine, the display screen does not show	battery voltage is lower than the equipment starting voltage	Use a multimeter to test whether the voltage at both ends of the battery is lower than 7V; The battery group needs to be charged by other means to make its battery voltage reach more than 8V;
Radiator overheating	Red light, icon flash	1.High ambient temperature, poor heat dissipation of equipment, and poor fan ventilation;2. The fan is damaged	1.Check the installation environment of the equipment, remove sundries in the air duct of the equipment, and ensure the smooth ventilation of fans;2. Replace the fan when the fan is damaged;
Charging flow	Red light,Icharge flash,icon flash	Charging over current protection check current detection abnormal, wrong operation	Restart several times if still can not be solved, need to return to the factory for maintenance
Load flow	Red light,icon flash	High load power	1. Reduce load power; 2. Restart and remove the fault; 3. No excessive sensibility and capacitive load;
Note:In addition to the battery voltage can not start, other faults can be referred to the PC background or mobile APP fault information;

5.3 System Maintenance

 In order to maintain the best long-term performance, it is recommended to conduct the following inspection twice a year.
• Make sure controller is securely installed in a clean, dry environment.
