Solar generation system consist of solar modules, solar controller, batteries (Group). It needs inverter if the output is 220V or 110V. The role of every part as follow:
(1) Solar modules: Solar modules are key part and highest valued part of the whole system. It has function of exchanging the shininess to electricity, or sending electricity to storage in batteries, or promoting load. The quality and cost of solar modules will determine the quality and cost of the entire system directly;
(2) Solar controller: Solar controller has function of controlling the working state of the whole system and over-charge and over-discharge to batteries. The qualified controller should have function of temperature compensating in the larger temperature difference place. Other value-added functions should be available option such as optical control switches, controllers, control switches;
(3) Batteries: Generally, the system use lead-acid batteries. For small micro-systems, also can used nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries. Its role is in a solar panel illumination will be issued to energy storage, to be released when needed.
(4) Inverter: It needs to provide 220VAC 110VAC Exchange power on many occasions. Because solar panel output of is 12VDC, 24VDC, and 48VDC. To be able to provide 220VAC electricity, this needed to exchange DC to AC. Hence the need to use DC-AC inverter devices. In some occasions, the need to use multiple voltage load, but also used DC-DC inverter devices, such as 24VDC the electricity conversion 5VDC the electricity (this is not a simple relief)
