The solar photovoltaic power generation system consists of solar panels, solar controllers, and batteries (groups)
Jun 21,2024
The solar photovoltaic power generation system consists of a solar cell pack, a solar controller, and a battery (group). If the output power supply is AC 220V or 110V, an inverter needs to be configured. The functions of each part are:
（1） Solar panels: Solar panels are the core component of solar power generation systems and the most valuable part of them. Its function is to convert the radiation ability of the sun into electrical energy, or send it to a battery for storage, or drive the load to work.
（2） Solar controller: The function of a solar controller is to control the working status of the entire system and provide overcharging and discharging protection for the battery. In areas with large temperature differences, qualified controllers should also have temperature compensation function. Other additional functions such as light control switches and time control switches should be optional for the controller;
（3） Battery: Generally lead-acid batteries, nickel hydrogen batteries, nickel cadmium batteries, or lithium batteries can also be used in small and micro systems. Its function is to store the electrical energy emitted by solar panels under illumination and release it when needed.
（4） Inverter: The direct output of solar energy is generally 12VDC, 24VDC, and 48VDC. To provide electrical energy to 220VAC appliances, it is necessary to convert the direct current energy generated by the solar power generation system into alternating current energy, so a DC-AC inverter is needed.
