Hybrid solar system refers to the solar power generation system both grid-connected and off-grid hybrid system, in which grid-connected refers to the DC power generated by solar modules through the grid-connected inverter converted into AC power that meets the requirements of the utility grid after directly accessing the public grid to sell electricity, while off-grid refers to the system consisting of solar panels, storage batteries, charge/discharge controllers, inverters, loads and other parts of the system, it is not connected to the grid and operates independently.

The advantages of grid-connected and off-grid solar systems are:

1. Wide range of application, can be used in areas without electricity or unstable power supply, such as: plateau, islands, pastoral areas, border posts and other military and civilian living power, as well as industrial power away from the grid.

2. Independent, self-sufficient, no need to connect to the grid, not affected by the grid.

3. Simple maintenance, stable and reliable operation, simple maintenance, long service life.

4. Green environmental protection, no pollution, no noise.
