The solar photovoltaic power generation system consists of a solar cell group, solar controller, and battery (group). If the output power supply is to AC 220V or 110V, the inverter needs to be configured. The role of each part is:
(1) Solar panel: Solar panels are the core part of the solar power generation system, and it is also the highest value part of the solar power generation system. Its role is to convert the radiation capacity of the sun into electrical energy, or send it to the battery to store it, or push the load work.
(2) Solar controller: The role of solar controller is to control the working status of the entire system and play a role in charging and discharge protection for batteries. In a place with large temperature differences, the qualified controller should also have the function of temperature compensation. Other additional functions such as optical control switches and time control switches should be the options of the controller;
(3) Battery: Generally, it is a lead -acid battery. In small and micro systems, nickel -metalized batteries, nickel -cadmium batteries or lithium batteries can also be used. Its role is to store the electric energy emitted by the solar panel when there is light, and then release it when it is needed.
(4) Disposter: The direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide electrical energy to the 220VAC electrical appliances, the DC electrical energy emitted by the solar power generation system needs to be converted to the transition power energy, so the DC-AC inverter needs to be used.
