3.1 Notes
- Read the entire installation section and familiarize yourself with the installation steps before installing.
- Be very careful when installing the battery. Wear protective glasses for the installation of lead-acid battery with openings.
- Avoid placing metal objects near the battery to prevent short circuit of the battery.
- The battery may produce acidic gas when charging, ensuring good ventilation around the environment.
- Please install indoors and outdoors to avoid direct sunlight and rain infiltration.
- Phantom connections and corroded wires can cause excessive heat to melt the insulation layer, ignite surrounding materials, and even cause a fire. Therefore, it is important to ensure that the connectors are tightened and the wires are secured with a binding band to avoid loose connections caused by the shaking of the wires when moving applications.

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 |

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;

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; |

| 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.• Make sure airflow around the controller is not blocked and remove any dirt or debris from the radiator.• Check all exposed wires for insulation damage caused by sun exposure, friction with other objects around, dry rot, insect or rodent damage, etc.Repair or replace the wires if necessary.• Tighten screws to all electrical terminals as recommended.• Check grounding of all parts of the system and verify that all grounding wires are firmly grounded and properly grounded.• Check all terminals for signs of corrosion, insulation damage, high temperature or burning, discoloration, and tighten terminal screws to recommended torque.• Check for dirt, nesting insects and corrosion and clean as required.• If arrester has failed, replace the failed arrester in time to prevent the controller or even other users' equipment from being damaged by lightning Note:Electric shock risk! ! !
