— the signal in the form of a smooth sine wave is as close as possible to the signal in ordinary household sockets. Inverters with these characteristics can be used for almost any type of load — including and for devices that are sensitive to the quality of the input voltage (for example, audio systems or amplifiers). At the same time, control circuits that provide a smooth sine wave are expensive, and most devices connected to autoinverters do not require a high quality signal. Therefore, it is worth specifically looking for such a device only if you plan to use it to power the mentioned sensitive load.
