System composition:
The large ground power station system is composed of solar cell array, grid connected inverter, AC junction box, transformer and so on. The capacity is above 1MW, and the site can be chosen in the roof of the plant and the open ground. The solar cell array directly converts solar energy to DC power under the condition of illumination. Through the grid connected inverter, the DC power is converted into alternating current, and then connected to the 10kV~35kV power grid after the transformer is boosted.
