The grid-connected energy storage solar power generation system can store excess power generation and increase the proportion of self-generated and self-used.

The system consists of solar panels, solar controllers, batteries, Hybrid inverters, current detection devices, loads, etc. When the solar power is less than the load power, the system is powered by the solar energy and the grid together. When the solar power is greater than the load power, part of the solar energy supplies power to the load, and part of it is stored by the controller.

The energy storage system is an important part of the power production process. Through the energy storage solution, it can realize self-generation and self-use, connect surplus electricity to the grid, and reduce the dependence of the grid; realize peak shaving and valley filling, and effectively utilize energy; power quality and improve the stability of the power system; establish a micro-grid energy storage system to provide stable power for areas without electricity such as isolated islands.
