The quality pwm solar charge controller is a key device widely used in the solar panel charging system. Its function is to send the electric energy collected by the solar panel into the battery, so as to realize the effective charging of the battery by the solar panel. How to maintain the quality pwm solar charge controller will be introduced in detail below.

Periodic inspection

(1) Check whether the output port is damaged, reveal the control circuit and make corresponding repairs, and fix the reverse switch problem at the same time.

(2) Check for any dust, dirt adhering to the controller, and clean it. Use a soft-bristle brush to lightly brush the surface of the controller, do not use sharp tools.

avoid overheating

The result of quality pwm solar charge controller is easily damaged by high temperature, so it is necessary to avoid the state of overheating. In order to solve this problem, you need to take the following steps.

(1) When installing the quality pwm solar charge controller under direct sunlight, please choose an installation location so that it can only receive direct sunlight towards the sun during certain hours, and be in shade at other times.

(2) Use a fan to reduce the operating temperature of the quality pwm solar charge controller. Prevent high temperature from causing equipment damage.

Replace the electrolytic capacitor according to the usage conditions. The electrolytic capacitor in the quality pwm solar charge controller is a vulnerable part, and its life is gradually shortened with the prolongation of use time. Therefore, the electrolytic capacitor must be regularly checked and replaced to ensure that the quality pwm solar charge controller can work normally.

Anti-static shock

quality pwm solar charge controller is a precision electronic part that is easily damaged by static shock. Therefore, proper measures must be taken to avoid this from happening.

(1) Please ground yourself before dealing with quality pwm solar charge controller.

(2) Before the controller is installed, please make sure the safety grounding of the household electrical system and provide an appropriate size for the quality pwm solar charge controller.

In summary, a solar charge controller is a very important piece of equipment that must be properly maintained and maintained to function properly. To ensure the long-term stable operation of the quality pwm solar charge controller, please follow the recommendations for maintenance and maintenance.
