Solar Street Light Controller Maintenance

The solar street light controller is applied in the solar photovoltaic lighting system. It is called solar charge and discharge controller, which coordinates the work of the solar panel, battery, and load. Solar controller is the core component of solar street lights, which has the function of light control, time control, charging and discharging, etc. Keep it dry in use, and do not touch the button at discretion. Malfunction must be in professional operation.

It can be seen how important the solar street lamp controller is. What should I do if such an important part breaks down? Luxman light will share with you some of our own conclusions on this issue.

1.Protection, troubleshooting, and maintenance of solar street lamp controller

Protection function of solar street lamp controller
Short circuit of photovoltaic panel The input terminal of the photovoltaic panel is short-circuited. When the short circuit condition is clear, the charging will continue automatically.
Overload If the current of the load exceeds the rated current of the controller, the controller will disconnect the load. In case of overload, it can only reduce the power consumption equipment at the load end and press the setting button once to eliminate it.
Load short circuit When the load is short-circuited, the controller will automatically protect it. After the controller automatically recovers the output, the protection action must be eliminated by pressing the setting button once.
Polarity reversal of the photovoltaic panel The polarity of a photovoltaic panel is connected reversely, the controller will not be damaged, and it will continue to work normally after correcting the wiring error.
Battery polarity reverse protection The battery polarity is connected reversely, the controller will not be damaged, and it will continue to work normally after correcting the wiring error.
Overheat protection The controller automatically protects the radiator by detecting whether the temperature of the radiator exceeds 85 ℃, and stops charging and discharging when the temperature of the radiator exceeds 85 ℃.

2.Troubleshooting of solar street lamp controller power generation system

Troubleshooting of solar street lamp controller power generation system
Phenomenon Solution
When there is direct sunlight photovoltaic module, the charging indicator (1) is not on; Check whether the wiring at both ends of the battery power supply is correct and whether the contact is reliable;
The load indicator (3) is on, but there is no output;

 

Please check whether the electric appliance is connected correctly and reliably;
The load indicator lamp (3) flashes fast and has no output;

 

 

There is a short circuit in the output. Please check the output circuit. After removing all loads, press the setting button once, and the controller will return to normal output;
Load indicator light (3) flashes and no output If the load power exceeds the rated power, please reduce the power consumption equipment. Press the setting button once and the controller will resume output.
