Many people are not clear about the on-grid and off-grid solar power system, not to mention several kinds of solar power system. Today, I will give you a popular science.
According to different application ，the common solar power system is generally divided into on-grid power system, off-grid power system, on and off-grid energy storage system.
1. TORCHN on-grid solar power system
On-grid solar power system consists of components, grid-connected inverters, PV meters, loads, two-way meters, grid-connected cabinets and grids. PV modules generate direct current from illumination and convert it into ac power through the inverter to supply load and send it to the power grid. The system does not need to be connected to batteries.
2.TORCHN off-grid solar power system
off-grid solar power system are generally used in remote mountainous areas, areas without electricity, islands, communication base stations, and street lights.The system generally consists of PV modules, solar controllers, inverters, batteries, loads and so on.The off-grid solar power system converts solar energy into electrical energy when there is light, and powers the load through the integrated solar control inverter and charges the battery at the same time;When there is no light, the battery supplies power to the AC load through the inverter.
3.TORCHN On and off-grid solar power system
are widely used in places where there are frequent power outages, or where the price of self-use electricity is more expensive than the on-grid price, and the peak electricity price is much more expensive than the trough electricity price.The system consists of PV modules, on and off-grid all-in-one, batteries, loads, etc.Convert solar energy into electrical energy when there is light, and use solar energy to control the inverter integrated machine to supply power to the load and charge the battery at the same time.When there is no light, it is powered by the battery.
Compared with the on-grid solar power system, this system adds a charge and discharge controller and batteries. When the grid is out of power, the PV system can continue to work, and the inverter can switch to off-grid working mode to supply power to the load.There are more application for on-off grid systems and richer modes.
