💡 Product Description
Solar Energy System

Solar panels produce DC electricity, which can be converted into AC electricity through an inverter for direct use by household or industrial loads. Extra DC electricity can charge the battery for backup use at night or during rainy days. Our inverters feature a state grid supplementing function, ensuring continuous power even when battery storage is low. Users can also utilize the state grid to charge batteries during low electricity price periods or sell excess energy back to the grid. For commercial and industrial systems, backup diesel generators can also be integrated.
