The common faults in solar controllers in the network system are mainly divided into the following: Unable to charge, the charging current is too small, the battery consumes fast, and the load cannot work. The following HTT will give you detailed introduction to the failure of the solar controller in the network system.
First, the solar panel cannot charge the battery.
Verify that the solar panel is connected correctly and whether the positive and negative pole is reversed.
The solar panel is blocked.
The specifications of the solar panel are correct. Whether the open circuit voltage satisfies the requirements of the controller.
The power of the Flat Roof Solar Racking System of the controller. Power is too much likely to cause the solar controller to be burned.
If the battery is full, the controller enters the floating stage, and the charging current will become very small.
Second, the battery is not enough, soon no electricity.
1, whether the battery capacity design is reasonable, the capacity is too small, and the time is naturally short. 2, the battery aging, the service life of the battery is generally 2-3 years, and the battery capacity is large, and the battery needs to be replaced regularly. 3, whether the battery is shorted during installation. Battery capacity due to short circuit is greatly reduced.
4, the load power exceeds the design power. Third, the load cannot operate
1. Confirm whether the load voltage is consistent with the output voltage of the controller. .
2, is there a short circuit, overload?
3, whether the controller load output is turned off manually?
4, the battery voltage is too low or high results in controller load protection.
