During the life of the inverter, the battery plays a vital role. The inverter converts the energy provided by the grid into direct current, and the battery is a device that stores the direct current. In the event of a power outage, the inverter draws power from the battery and converts it back to AC form to run all household loads. Sine wave is an improved advanced technology that can provide your home with grid-like power during a power outage, thereby increasing the performance and lifespan of connected equipment. Square waves generate heat and hum, which reduces the life of connected devices. If users need to operate complex electronic equipment, such as televisions, refrigerators, mixers, grinders, etc., it is recommended to use a sine wave inverter.
