Integrated solar street light Supplier China shares that the solar power generation system is composed of solar cell, solar controller and battery. If the output power supply is 220V or 110V, the inverter shall be configured. The functions of each part are:
Solar panels: solar panels are the core part of the solar power system and the most valuable part of the solar power system. Its function is the solar radiation capacity into electricity, or sent to storage batteries, or to promote the load work. The quality and cost of solar panels will directly determine the quality and cost of the whole system;
Solar controller: the role of the solar controller is to control the working state of the whole system, and the battery has a charge protection, over discharge protection. Where the temperature difference is large, the qualified controller should also have the function of temperature compensation. Other additional functions such as light switch and time switch should be optional for the controller.
Battery: generally lead-acid battery, small and micro system, also available nickel hydrogen battery, nickel cadmium battery or lithium battery. The idea is to store the energy generated by the solar panels when there is light and release it when needed.
Inverter: in many cases, need to provide 220VAC, 110VAC ac ac power supply. As the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. To power a 220VAC appliance, a dc-ac inverter is required to convert the direct current energy from the solar power system into AC energy. Dc-dc inverters are also used in some situations where multiple voltages are required, such as converting the electrical energy from 24VDC to 5VDC (note that this is not a simple step-down).
