 Off Grid Solar Photovoltaic System (Solar PV System)

Independent from grid, off grid solar photovoltaic system can supply electricity to radio-relay stations, telephone booths, communication stations, scrolling panels, street lighting devices, etc. It can also be used for power supply in places or countries where traditional power is unstable or power system is incomplete.

Off grid solar photovoltaic system is a kind of new power supply which utilizes controller to manage the charge and discharge of storage battery and provide electricity for alternating current load via inverter or for direct current load. It is widely used in continental plateaus, islands, mountainous areas, field works, and some other places. Utilizing inexhaustible natural energy source, off grid solar photovoltaic system has effectively relieved the electricity utilization pressure in power-shortage areas.

Off grid solar photovoltaic system is fitted with storage battery, so electric energy can be stored for supplying power in the night. It can also be used in conjunction with other electric power resource such as wind energy source, improving the reliability of electricity supply.

Functions of the Constituent Parts of Off Grid Solar Photovoltaic System
Solar photovoltaic panel is the power generating part.
Photovoltaic controller can adjust and control the generated electric energy. On one hand, the controller transmits adjusted electric energy to direct current load or alternating current load. On the other hand, it transmits the excess energy to storage battery, and when the generated electricity can not meet load needs, the controller will transmit the electric energy stored in storage battery to load. When the storage battery is fully charged, the controller can prevent the battery from overcharge. When the electric energy stored in storage battery is fully discharged, the controller can prevent the battery from over discharge. So the performance of controller exerts a tremendous influence on the service life of storage battery and even the reliability of the off grid solar photovoltaic system.
Storage battery is used to store electric energy and ensure reliable electricity supply in the night or on cloudy and rainy days.
Inverter is used to convert direct current to alternating current.
