Power generation system in solar LED street light

Everyone knows that a solar panel is a power generation system in a solar LED street lamp, which is composed of a solar cell module, a solar controller, and a battery (group).

1. Battery: Generally, there are two types of lead-acid batteries: 12V and 24V. Nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries may be used in small-micro power generation systems. Its function is to store the electrical energy converted by the solar panel when there is light, and then release it when it is needed;

2. Solar controller: The function of the solar controller is to control the working state of the entire solar LED street lighting system, and to protect the battery from over-charging and over-discharging. At the same time, in the place with large temperature difference, the quality controller is also Should have temperature compensation function, other additional functions such as light control switch, time control switch should be the basic function of the controller;

3. Inverter: AC220V and AC110V AC power supply are required in many occasions. Since the direct output of solar energy is generally DC6V, DC12V, DC24V, DC48V, in order to provide corresponding power to AC220V appliances, solar power generation system is required. The DC power generated is converted into AC power, so DC-AC inverters are required. In some cases, when multiple voltage loads are required, DC-AC inverters can also be used, such as 24VDC power. Converted to 5 VDC of electricity;

4. Solar panels: Solar panels are the core components of solar power systems and the most costly part of solar power systems. Its function is to convert solar energy into electrical energy and send it to the storage of the battery to drive the load to work. The quality and cost of the solar panel will directly determine the quality and cost of the entire solar LED street lighting system.
