太阳能离网发电系统的组成及作用 Functions of the components of solar power systems.

太阳能发电系统由光伏组件，光伏控制器，蓄电池等组成，若输出为交流220V&110V, 还需配置光伏逆变器。

光伏组件：是光伏发电系统的核心部分，其作用是将太阳能的光能转换为电能，或送往蓄电池中存储起来，或推动负载工作。

光伏控制器：作用是控制整个系统的工作状态，并对蓄电池起到过充保护和过放保护的作用，控制器还具备温度补偿，光控，时控等其他附加功能。

蓄电池：一般为铅酸电池，其作用是在有光照时将太阳能电池板所发出的电能存储起来，到需要的时候再释放出来。

逆变器：当需要提供220V AC,  110V AC交流电的时候， 需要将光伏组件发出的电转换成负载所需的交流电，此时就需要使用DC-AC逆变器； 在某些场合，需要使用多种电压的负载时，也要用到DC-DC逆变器例如将24V转换成5VDC（注意不是简单的降压。）

Offgrid solar power system consists of solar panels, solar controller, batteries. Sometimes, solar inverter will be required when loads need 220V or 110V AC voltage power.

Solar panels: is the central part of the whole solar system, transmit sun’s light energy into electrical energy, or to the battery, or to promote load work.

Solar controller: to control the entire system working state, and to protect battery against over-charge and over-release damage. Besides, controller also has additional function of temperature compensation,light control and time-control, etc.

Batteries: Lead-acid battery generally, to store solar power electricity or release and charge loads.

Inverter: When you need to provide 220V AC, 110V AC alternating current, you need to convert the electricity emitted by the photovoltaic module into the alternating current required by the load, then you need to use a DC-AC inverter; in some occasions, you need to use a variety of voltages When the load is used, a DC-DC inverter is also used to convert 24V to 5VDC (note that it is not a simple step-down.)
