Off-grid systems work by combining wind power and photovoltaic power. When there is enough wind, wind turbines convert wind energy into electricity; at the same time, photovoltaic panels are converting sunlight into DC energy. Both types of power are first managed by a controller to ensure that they are used efficiently. The controller monitors the status of the batteries and stores excess power in the batteries in case it is needed. The inverter is responsible for converting DC power to AC power for AC loads such as household appliances. When there is insufficient wind, sunlight or an increase in load demand, the system releases power from the batteries to supplement the power supply, ensuring stable system operation. In this way, the PV off-grid system achieves an independent and sustainable power supply by integrating multiple renewable energy sources.
