what is the difference between OFF GRID AND ON GRID? Jul 21, 2021

Generally, we divide solar power generation system into off grid (independent) system, on grid connected PV system and solar hybrid system. When users choose to install solar photovoltaic power generation system, they must first confirm whether to use off grid power generation or on grid connected power generation. The functions of the three systems are not the same, the components of the system are not the same, and the cost is also greatly different.

Off Grid Solar System means that the electricity from the solar system and the power station is independent and separate. Off grid is mainly composed of solar panels, energy storage batteries, charge and discharge controllers, inverters and other components;

On Grid Solar System connection means that it must be connected to the public power grid, that is, solar photovoltaic power generation, home power grid and public power grid are linked together, which is a power generation system that must rely on the existing power grid to operate. That is to say, the grid connection is the connection between the solar system and the power from the power station to power the electrical appliances together. If there is surplus electricity generated by the solar energy, it can also be transmitted to the grid for other families around. The grid connection needs professional technicians to operate, and the grid connection also needs the approval of the power station. It seems to be illegal to connect the grid without permission.
