With the continuous adjustment of the energy structure and the increasing demand for energy in recent years, new, environmentally friendly and pollution free road lighting projects represented by solar street lights have been used by more and more places at all levels for a few years During the process, there have been many problems, the following for everyone to explain the solar charg controller failure and treatment

1. There is voltage on the solar panel, but it can not be charged. The solar indicator is not on. Check whether the controller's solar panel interface is reliable

2. Charging indicator blinks rapidly: The system voltage overpressure, check whether the battery is open, or whether the battery is connected reliably. Or the charging circuit is damaged

3. Charging indicator goes out, the battery voltage is normal, no output, in this case, wait for about 10 minutes, the load will automatically open

4. Battery indicator light is not lit: battery power failure, please check the battery link is correct, the battery voltage is below 10.8V

5. Battery indicator light flashing, no output: battery over discharge, full of regret automatic recovery

6. The load indicator flashes slowly, no output: the load power exceeds the rated power, reduce the load power, reconnect to resume

7. The load indicator flashes rapidly and the load is not working: The load is shorted

8. Load indicator light, but the load does not work Check the load terminal connection is reliable

9. The whole light is not bright. Solar street light for outdoor lighting, often encounter high temperature and rain, low temperature rain and snow, and solar street light controller is usually installed in the light pole, easy to cause water to the controller short circuit

First: observe the controller terminal water rust situation, if possible, the controller has been damaged;

Second: further battery voltage measurement, 12V solar street lamp power supply system, the battery voltage is lower than 10.8V, the controller can not start normally led to the solar panel can not be charged to the battery through the controller

(1) the battery dug out, through artificial charging, the battery voltage is full, and then install

(2) to find a sunny day, the positive and negative battery positive and negative solar panels directly connected (not through the controller) 1 hour removed, and then were connected to the controller

Third: Then check Hung Yi Cheung panels, under normal operating conditions whether there is voltage and current output.

(1) first check the line for short circuit or off phenomenon

(2) Re check the junction box diode, if there is no voltage output, the junction box may be the diode burning, you can directly subtract the diode and then test, if still no output, you can consider replacing the solar panels;

Fourth: check the light source, only to the light source to see if it is lit, not bright then replace the light source(1) lamp flashing. Cause of this failure, poor line access, battery power loss, a serious decline in storage capacity, the line is no problem, replace the battery.

(2) light a short time, short rainy days duration. Battery storage capacity is usually decreased, resulting in storage enough. Replace the battery can be reasonable.

(3) incomplete solar street light source. Many solar street lights using LED matrix light source, in addition to the quality of LED light source itself, some beads Weld will cause this situation. The solution is to replace the corresponding lamp beads, welded firmly or replace the entire lamp head.
