This diagram shows the operation of a solar storage system with the Delong Top Energy 51.2V 100Ah - 5.12kWh lithium battery. Energy is supplied by solar panels, the grid or a generator, then stored in the battery. A hybrid inverter converts this energy to power your appliances: refrigerator, TV, air conditioning, oven, etc.
The battery serves as the heart of the system, optimizing self-consumption, securing your installation in the event of a power cut, and reducing your dependence on the grid. This system is ideal for homes, businesses or isolated sites looking for a reliable, long-lasting, high-performance energy storage solution.
