Solar panels: Solar panels are the core of solar power systems and the most valuable part of solar power systems. They are used to convert the solar radiation into electrical energy, or to be stored in batteries, or to drive loads. .
(2) Solar controller: The function of the solar controller is to control the working state of the whole system, and to protect the battery from over-charging and over-discharging. In places with large temperature difference, the qualified controller should also have temperature. Compensation function. Other additional functions such as light control switch, time control switch should be optional for the controller;
(3) Battery: Generally it is a gel battery. In small and micro systems, nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries can also be used. The function is to store the energy generated by the solar panels when there is light, when needed. Release it again.
(4) Inverter: The direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to supply electric energy to 220VAC electric appliances, it is necessary to convert the DC electric energy generated by the solar power generation system into AC electric energy, so DC-AC is needed. Inverter.
