The on-grid photovoltaic power generation system structure includes solar battery arrays, DC/DC converters, DC/AC inverters, AC loads, and transformers. It converts DC power output by the solar cell array into AC power with the same amplitude, frequency, and phase as the grid voltage.

This system provides flexible power: when sunshine is strong, it supplies the AC load and feeds excess electricity into the grid. During insufficient sunshine, it draws power from the grid to ensure continuous supply.

• Cost Reduction: Eliminates the immediate need for large battery banks if the grid is stable, reducing initial maintenance and replacement costs.
• Income Generation: Excess power can be harvested with inverters and LiFePO4 batteries and fed back into the power grid.
• Unrestricted Access: Not limited by the battery's state of charge; you can access grid electricity at any time.
• Maximum Efficiency: Solar plate arrays are designed at optimal inclination angles to maximize annual power generation.
• Peak Shaving: Provides maximum electricity during summer peaks when refrigeration and air conditioning use is highest.
