Usually, the system is mainly composed of solar photovoltaic components, combiner boxes, inverters, transformers and distribution equipment, and at the same time, auxiliary systems such as monitoring systems, active and reactive power control systems, power prediction systems, five-defense systems and reactive power compensation devices are added to form a complete photovoltaic power generation system. Usually, the system is mainly composed of solar photovoltaic components, combiner boxes, inverters, transformers and distribution equipment, and at the same time, auxiliary systems such as monitoring systems, active and reactive power control systems, power prediction systems, five-defense systems and reactive power compensation devices are added to form a complete photovoltaic power generation system. The following shows the structure of an independent photovoltaic power generation system, which mainly includes an automatic solar tracking system, a single-chip controller, an inverter, a DC boost system, a solar panel, a charger, a battery, etc. When the sunlight is strong, the solar cell directly provides low-voltage DC power to the DC boost circuit, and the charger is used to store electrical energy in the battery; when the sunlight is weak, the solar cell cannot meet the power generation requirements, and the battery will provide low-voltage DC power to the DC boost circuit. In this way, the stability and continuity of the power generation system can be guaranteed. The boost circuit will increase the low-voltage DC power to 330V high-voltage DC power, and use the inverter to convert it into 50 / 220V AC power, and then return it to the controller through the detection circuit to control the closed loop.
