Precautions and troubleshooting methods during the installation of solar street lights

Nowadays, solar lights benefit all over the world, but there are still many problems that accompany them. For example, they don’t light up after installation. This may be a problem in some aspects of assembly in addition to the problem of accessories. Although the installation is relatively simple, just assemble It also requires a certain amount of technology.

In order to avoid failure as much as possible, the solar lamp should be debugged before installation, and choose a sunny day. If it is installed on a cloudy or rainy day, it will only consume power and not charge after the lamp is turned on, which is not good for the battery, which will not reach the design. Claim. Be careful not to turn on the light on the day of installation. Connect the controller after installation, but do not connect to the load. After charging for one day the next day, connect the load in the evening, so that the battery capacity can reach a higher level. Of course, doing so will increase some labor costs. The angle of the battery panel is generally designed by the manufacturer according to the degree of inclination, so as to ensure a better charging capacity in winter. However, the direction angle is determined during installation. When the solar panel is assembled underground, it is found that the angle is deviated after the pole is erected. If it is almost the same, it is generally not adjusted. The angle deviation of the solar panel not only affects the charging, but also affects the solar panel voltage under the same illuminance, which will cause a relatively large error in the turn-on time of the solar lamp. Therefore, when assembling on the ground, try to adjust the azimuth angle of the solar panel to be consistent. Try not to shield the solar panel during installation to achieve the lighting effect.

When the solar street light fails after installation, it is generally divided into the following situations:
. There is voltage on the solar panel, but it cannot be charged, and the LEDI green light is off. Check whether the solar panel terminal interface of the controller is in reliable contact.
. The charging indicator LEDI (green light) flashes quickly. The system voltage is over-voltage. Check if the battery is open circuit or if the battery is connected reliably. Or the charging circuit is damaged.
. The load indicator LED (red light) is on, but the load is not working. Check whether the load terminal wiring is reliable.
. The load indicator LED (red light) flashes quickly, and the load is not working. The load is short-circuited.
. The load indicator LED (red light) flashes slowly, and the load is not working. The load power is too high.
. The LED is red and the load is not working. The battery voltage is protected. Please charge.
. The lamp head flashes. The cause of this failure is poor line contact, battery power loss, and serious decline in power storage. If the line is okay, replace the battery.

Of course, the failure of solar lights is not entirely caused by some human factors or environmental factors. The main reason is the design and materials of the solar street lights themselves, so the quality is king.
