What are the tips and methods to solve solar path lights failure

In solar lighting systems, light source failure is a common problem, especially when the lamp beads do not light up. To address this problem, the quality of the soldering points should be checked first. Use a magnifying glass and soldering tools to carefully observe the connection between the lamp beads and the circuit board. If traces of cold soldering are found, a hot air gun or electric soldering iron should be used to re-solder to ensure that the soldering points are full and firm. If the soldering is good but the lamp beads still do not light up, there may be quality problems with the light source itself. At this time, a new light source that matches the parameters of the original lamp needs to be replaced.

The problem of light source flickering is often closely related to unstable power supply. It is recommended to use a multimeter to detect the voltage of the battery. If the voltage is lower than the normal range (for example, the voltage of a 12V battery is lower than 11V), the battery should be charged in time. If the problem persists after charging, it may be that the battery is aging and needs to be replaced with a new battery. At the same time, check whether the line interface is loose or oxidized, clean the interface and reconnect it to ensure stable current transmission.

In the process of troubleshooting controller failures, the principle of systematization should be followed. First, check whether the solar panel is blocked, clean the surface dirt and other obstructions to ensure that it can fully receive sunlight. Next, check whether the battery connection is firm and tighten the terminal with a screwdriver. If the controller is short-circuited or open-circuited, use a circuit tester to detect the continuity of the circuit, locate the fault point, and then repair or replace the damaged circuit. When the controller is overloaded, reduce the load or replace the adapted controller. In addition, the controller may also fail if it is damp or overheated, so it should be kept dry and heat dissipation measures should be added, such as installing a heat sink or fan.

When solving battery failures, the actual situation should be taken into consideration. If the battery leaks, replace it with a new one immediately and clean the surrounding area to prevent corrosion. For batteries with degraded performance, you can try to activate them by charging and discharging with a small current cycle, but if they cannot be restored, they need to be replaced. When choosing batteries, it is recommended to give priority to high-temperature and low-temperature resistant models to adapt to different climatic conditions. During installation, ensure that the battery is firmly fixed to avoid loose connections due to vibration.

For solar panel troubleshooting, detail processing is particularly important. If the connection of the panel is not firm, re-weld or tighten the wiring. Use a voltmeter and an ammeter to detect the output parameters of the solar panel. If the open circuit voltage is normal but there is no current, it may be due to a poor solder joint or a loose joint, which needs to be checked and repaired. If the solar panel is seriously damaged, it is necessary to replace it with a new one and ensure its compatibility with the controller and the battery. In addition, regularly cleaning the surface of the solar panel to remove dust and dirt will help effectively improve its power generation efficiency.

When dealing with line faults, safety regulations must be followed. When using insulating tape to deal with line damage, ensure that the number of wrapping layers is sufficient and the seal is good. For aging or worn lines, new lines should be replaced in time and connected with special crimping pliers. During the wiring process, strictly distinguish between positive and negative poles to avoid short circuits. In addition, installing a leakage protector can significantly improve the safety of the line and ensure the stable operation of the system. Through the above measures, the incidence of solar lighting system failures can be effectively reduced, and its overall performance and service life can be improved.
