Inverter
Inverter is used to convert 12 volt system to 220 volt and 50Hz. There are two kind of inverters, modified sinewave and true sinewave inverters.
Modified sinewave
Modified sinewave inverters are cheap and is the most common type of inverter on the market. They can run most common tools and appliances, including microwaves, refrigerators, hand tools, televisions and computers. Devices that require true sine wave will not run on modified sinewave inverter. Remember if your product does not work with modified sinewave inverter so it mean you need to buy true sinewave inverter.
True Sinewave inverter
True sinewave inverters are expensive. These products require true sinewave inverter high-end audio video units, plasma displays, gaming systems, and certain scientific testing equipment.
