A grid-connected power generation system is a solar photovoltaic power generation system connected to the conventional grid, jointly undertaking the power supply task.

It directly supplies AC loads, then feeds the remaining electricity into the grid, or directly integrates all generated electricity into the grid. The grid-connected power generation system mainly consists of solar cell arrays, grid-connected inverters, grid connection boxes, and the national grid.

Composition and Working Principle of Solar Grid-Connected System

1. A power generation system that converts solar radiation energy into electrical energy through solar cells (also known as photovoltaic cells) is called a solar cell power generation system (also known as a solar photovoltaic power generation system).

2. The grid-connected inverter is the core component and technical key of the grid-connected photovoltaic power generation system. In addition to converting the DC power generated by the photovoltaic array into AC power, unlike ordinary inverters, the grid-connected inverter also needs to control the frequency, voltage, current, phase, active and reactive power, and power quality (voltage fluctuations, higher harmonics) of the converted AC power, ensuring that the voltage and frequency of the converted AC power match those of the grid.

The grid connection box plays a certain auxiliary role in the photovoltaic power generation system, enabling functions such as metering and protection.

Mangzhong Construction is dedicated to photovoltaic power station investment, development, design, construction, intelligent operation and maintenance, professional consulting services, and photovoltaic power station equipment recycling. After customers express installation needs, our engineers will arrive on-site according to the scheduled appointment for professional and efficient on-site surveys, providing you with customized design solutions. To ensure the rigor of subsequent detailed design and further enhance our service quality, we conduct rapid on-site surveys. The design team uses professional tools (accurately measuring roof area, evaluating roof load capacity, surrounding environment, and shading, etc.). Combining different types of residential roofs and buildings, we scientifically design the optimal solution to ensure maximum returns and long-term stable performance.
