Solar power system composition
Solar power system consists of solar batteries, solar controller, battery (group) components. If the output power to 220V AC or 110V, also need to configure inverter. The role of each part as follows:
1. Solar panels: solar panel solar power system in the central part of the solar system, the highest part of the value. Its role is to the sun's radiation is converted to electrical energy stored in batteries or sent to, or promote the work load.
2. Solar Controller: Solar controller's role is to control the working status of the entire system, and played a battery charge protection, over-discharge protection. In the large temperature difference, the controller should have qualified temperature compensation function. Additional features such as light control switch, the switch should be the controller options.
3. Battery: lead-acid batteries, small micro-system, also used nickel metal hydride batteries, nickel cadmium batteries or lithium batteries. Its role is when there is light energy emitted by the solar panels is stored up to the time required to re-release.
4. Inverter: On many occasions, we need to provide 220VAC, 110VAC AC power source. Because of the direct solar energy output are generally 12VDC, 24VDC, 48VDC. To provide electrical power to 220VAC electrical, solar power generation system needs to be issued by the DC energy into AC electrical energy, and therefore requires the use of DC-AC inverter. In some cases, when you need to use a variety of voltage, load, also used DC-DC inverter, such as the 24VDC power into 5VDC power (note, not a simple step-down).
