A, what is the reason for solar street lights do not light up
Solar street light energy saving, cost saving, is a new type of green street light, but some customers reflect the solar street light after installation does not light up, what is the reason? Solar street lights do not light up for the following reasons
1、Wiring error
When wiring the positive and negative polarity of the lamp head is reversed is not bright, if it has not been extinguished, then it may be the pool plate is connected to the reverse.
2、The capacity is too small
According to the relevant regulations, the solar lithium battery from the factory to transport the battery storage capacity is controlled at about 30%, if not installed for a long time or installed after the rainy weather, it will consume the stored electricity, when the electricity is used up, it is natural not to light up.
3, quality problems
Poor quality of solar street lights may also lead to not bright, quality problems may exist in the line failure or low power generation efficiency, etc., encounter this situation can only contact the manufacturer to send back for repair or let professionals to visit the home.
4, battery damage
If the solar battery is damaged, it will affect the performance of charging and discharging, resulting in shorter lighting time of solar street lights, solar street lights do not light up and other failure phenomena.
5, solar street light controller damage
Solar street light controller regulates the solar street light charging and discharging time and voltage power and other parameters, it is damaged will lead to solar street light charging and discharging out of control, and thus can not light up.
Second, the solar street light does not light up the repair steps process
1, check the battery, solar street light is not bright is likely to be damaged battery, remove the battery and replace it with a new battery for inspection, if the light is the battery problem, the new battery line through the good, according to the original wiring line can be; if still not bright, we must check other parts.
2, check the solar panel to see if it can be charged normally, mainly by looking at the voltage plate there is no current to determine. If the battery panel connector is not welded or the aluminum foil has no current, it needs to be replaced; if it is caused by the accumulation of dust, it can be cleaned and maintained.
3, check the controller, the same, remove the controller, replace the model matching the controller, if the normal light, it means that the controller is damaged, replace it, if it still does not light, then continue to check.
4, check the lamp head, if the solar street lamp head using the power is large, may cause excessive discharge of the battery aging in advance, if the power is small, the brightness is not enough to cause unnecessary cost of waste, the lamp head is damaged, remove the lamp head and replace it.
5, if the above methods still can not solve the problem, it may be the quality of solar street lights, you need to contact the manufacturer for repair or replacement.
Third, how to maintain the maintenance of solar photovoltaic street lights
1, in case of high winds, heavy rain, hail, snow, etc., measures should be taken to protect the solar cells to avoid damage.
2, the solar cell lighting surface should always be kept clean, such as dust or other dirt, should first rinse with water, and then gently dry the water stains with clean gauze, do not use hard objects or corrosive solvents to rinse.
3, with the solar cell array matching the use of the battery pack, should be used in strict accordance with the use of battery maintenance methods.
4, regularly check the wiring of the solar street light electrical system to avoid loose wiring.
5, do not let hard or sharp objects hit the solar panel, otherwise it will damage the solar panel.
