The GGD Photovoltaic Grid-connected Cabinet is designed for solar photovoltaic grid-connected power generation systems. It serves as the electrical energy conversion, distribution, and control unit between the photovoltaic inverter and the step-up transformer or load. Positioned as the main export point in the photovoltaic system, it acts as the dividing point between the photovoltaic power generation system and the grid. For low-voltage grid-connected photovoltaic power plants, the photovoltaic grid-connected cabinet can also be equipped with additional devices for functions such as metering and protection.
Structural Features
