The controller of the solar lawn light is mainly used to control the charging and discharging of the battery. A basic photovoltaic application system is composed of photovoltaic panels, batteries, solar controllers and loads. K1 and K3 are charging switches, and K3 is a discharging switch, all of which are part of the solar control center. Regardless of the size of the solar luminaire, a well-functioning charge-discharge controller is essential. In order to prolong the service life of the battery, its charging and discharging conditions must be limited to prevent overcharging and deep charging of the battery.
In places with large temperature difference, a qualified controller should also have temperature compensation function. At the same time, the solar controller should have both street lamp control functions, light control and time control functions, and should have the function of automatic load cutting at night, which is convenient for extending the working time of street lamps in cloudy and rainy days. Solar mobile power is a new type of power source that converts solar energy into electrical energy and stores it in the battery, and has a mobile nature. The storage battery can be any form of power storage device, and generally consists of three parts: solar photovoltaic cells, storage batteries, and voltage regulating elements. At present, the energy crisis and the deteriorating environmental problems caused by fossil fuels have been paid more and more attention by people. At present, digital products are becoming more and more popular. The solar mobile power supply is developed under this background.It is difficult to say the lifespan of solar garden lights, which is mainly based on the lifespan of each different component; for example, the lifespan of solar panels can reach more than 25 years; the lifespan of lamp poles can also reach more than 30 years; They are all LED light sources. The biggest feature of LED light sources is that they have a long life span of up to 50,000 hours. Assuming that they are used for 10 hours a day, the life span is at least 10 years. And so on some reasons that will affect the service life of solar garden lights. In general, the service life of our solar garden lights is still very good, and they are the most suitable for use as street lights.
