1. Check whether the name of the solar battery is clean and whether there is a scene of corruption and leakage. If there is more dirt on the shell, wipe it with a wet cloth dipped in washing powder. LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy.
It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape.
2, check whether the appearance of the solar battery is concave or bulging;
3. Tighten the connection screws between the battery cells at least once every six months to prevent loosening, resulting in poor contact and other faults. When maintaining or replacing batteries, tools (such as wrenches) must be equipped with insulation sleeves to prevent short circuits.
4, the battery should be charged in time after discharge. Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap. In case of continuous rainy days and insufficient battery charge, end or shorten the power supply period of the power station to avoid over-discharge of the battery. The maintenance personnel of the power station should regularly charge the batteries in a balanced manner, sometimes 2 to 3 times every quarter. The storage battery that has been out of use for a long time (more than 3 months) should be recharged before it is put into operation.
5, winter to do a good job of heat preservation battery room, summer to do a good job of ventilation battery room, battery room temperature should try to control between 5℃~25℃.
6. Adhere to the cleanliness of the lighting surface of the solar module array. In areas with little rain and large sandstorms, it should be cleaned once a month. When cleaning, it should be washed with clean water first and then dried with a clean soft cloth. Do not wash with a decaying solvent or wipe with a hard object. Cleaning should be chosen in the dark hours or in the morning and evening. It should be avoided in the daytime, when the photovoltaic module is heated by the sun, the module should be cleaned with cold water. Very cold water will crack the glass cover plate of the photovoltaic module.
7, regularly check whether the connection between photovoltaic module panels is firm, whether the connection in the square junction box is firm, according to the need to tighten; Check whether the photovoltaic module is damaged or abnormal, such as damage, grid dissipation, hot spots, etc.; Check whether the bypass diode in the junction box of pv module works abnormally. When the photovoltaic module presents problems, it should be replaced in time, and the specific device distribution position of the module in the photovoltaic array should be recorded
