Solar inverter is a converter that transforms direct current (DC) energy (from batteries or storage batteries) into constant frequency and voltage alternating current (AC) or frequency and voltage regulated alternating current (AC) (typically 220V, 50Hz sine wave). It consists of an inverter bridge, control logic, and filter circuits. It is widely used in air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. When driving to work or traveling, an inverter can be connected to a battery to power appliances and tools. Car inverters with output via the cigarette lighter socket are available in power ratings of 20W, 40W, 80W, 120W to 150W. Higher power inverters require connection to the battery. Connecting household appliances to the output of the power converter allows for the use of various electrical appliances inside the car. Suitable electrical appliances include: mobile phones, laptops, digital camcorders, cameras, lights, electric shavers, CD players, game consoles, PDAs, power tools, car refrigerators, and various travel, camping, and medical emergency appliances.

Using office equipment (such as computers, fax machines, printers, scanners, etc.);

Using household appliances (such as game consoles, DVDs, stereos, camcorders, electric fans, lights, etc.); or when batteries (for mobile phones, electric shavers, digital cameras, camcorders, etc.) need to be charged.
