Common three-point failures of solar controllers in off-grid systems

50 Published by admin 6月 06,2020

Common faults of solar controllers in off-grid systems are mainly divided into the following contents: unable to charge, the charging current is too small, the battery consumes power quickly, and the load cannot work. The following snadi inverter manufacturers will introduce them in detail.

1. The solar panel cannot charge the battery.
1. Confirm whether the solar panel is connected correctly and whether the positive and negative poles are reversed.
2. Whether the solar panel is blocked.
3. Whether the specifications of the solar panel are correct. Whether the open circuit voltage meets the requirements of the controller.
4. Whether the power of the solar panel exceeds the rated system of the controller. Too much power may cause the solar controller to burn out.
5. If the battery is full, the battery is full and the controller enters the floating charging stage, the charging current will become very small.

Second, the battery power is not enough, and soon no electricity.
1. Whether the battery capacity design is reasonable, the capacity is too small, the use time is naturally short.
2. The battery is aging, the service life of the battery is generally 2-3 years, the capacity of the battery is greatly attenuated, and the battery needs to be replaced regularly.
3. Whether the battery has a short circuit during installation. The capacity of a battery damaged by a short circuit is much reduced.
4. The load power exceeds the design power.

Third. The load cannot work
1. Confirm whether the working voltage of the load is consistent with the output voltage of the controller.
2. Is there any short circuit and overload in the load?
3. Is the controller load output manually turned off?
4. Whether the battery voltage is too low or too high leads to controller load protection.
