What is a hybrid system?
The grid-connected energy storage system refers to the power generation and energy storage system that is integrated into the
grid, and the generated electricity may be used for its own use, and the surplus is supplied to other users in the grid. The
entire system is a power generation system including photovoltaic module arrays, photovoltaic controllers, battery packs, battery
management systems (BMS), inverters, and corresponding energy storage power station joint control and dispatching systems.
