Description Product description: The solar panel receives the energy of the sun to charge the battery. Electricity-improved sine wave inverters can reliably convert direct current from batteries to alternating current, which can then power lights, computers, medical equipment, and a variety of devices. The inverter has built-in independent cooling fans and an additional USB charging port to connect to many devices. The solar controller monitors the system while controlling the charging and discharging of the battery. (Note: the battery needs to be purchased by you) About corrected sine wave output: AC corrected sine wave output has little interference, low noise and high load capacity, which will not affect the service life of the equipment.
