We all know that solar panels are solar LED lights in the power generation system, which is composed of solar modules, solar controller, and battery (group) components.
1, battery: lead-acid batteries have both 12V and 24V, small and micro generation systems may be used nickel metal hydride batteries, nickel cadmium batteries or lithium batteries. Its role is to store the electrical energy when the solar panels converted, and release them when needed to use.
2, Solar Controller: Solar controller's role is to control the working status of the entire solar LED street lighting system, and played a battery charge protection, over -discharge protection, while the large temperature difference, quality controller also should have temperature compensation, other additional features such as light control switch, the switch should be the basic functions of the controller;
3, inverter: In many occasions, we need to provide AC220V, AC110V AC power, due to the direct output of solar energy are generally DC6V, DC12V, DC24V, DC48V, in order to provide electrical power to AC220V, solar power system needs to be issued by the DC energy into AC power, requiring the use of DC-AC inverter, while in some cases requires the use of multiple load voltage, and DC-AC inverter can be used , such as the power 24VDC converted to 5VDC power ;
4, solar panels: solar panel solar power system is the core component of the solar system, the highest part of the cost. Its role is to store the energy converted by solar energy in batteries, and work for promote the work load, the quality and cost of solar panels will directly determine the quality and cost of the entire solar LED street lighting system.
