Small Solar Power System
Small solar power system is composed of a monocrystalline/polycrystalline solar panel, battery, photovoltaic controller. If you need to connect AC load, you need AC converter - inverter. An inverter is an electrical appliance that converts direct current into alternating current.
(1)Solar panels: solar panels are the core of solar power systems, and are the most valuable part of solar power generation systems. Its function is to convert the radiant power of the sun into electrical energy, or to the storage battery storage, or to promote the work of the load.
(2) Solar controller: the role of solar controller is to control the working state of the whole system, and the battery has played the role of overcharge protection, over discharge protection. In the place where the temperature difference is large, the qualified controller should also have the function of temperature compensation. Other additional functions such as light operated switches and time controlled switches should be optional for the controller.
(3) Batteries: generally lead-acid batteries, small and micro systems can also be used nickel hydrogen batteries, nickel cadmium batteries or lithium batteries. The function is to store the energy emitted by the solar panel when it is illuminated, and then release it when needed.
(4) Inverter: the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide electrical energy to 220VAC electric appliances, it is necessary to convert the DC energy generated by the solar power generation system into alternating current energy, so the DC-AC inverter is needed.
