Pseudo Sinus voltage converters transform direct current (DC) from the battery bank into usable alternating current (AC) 230V for domestic installations. They are called Pseudo Sinus because they provide a wave that is less pure and less regular, composed of a series of "staircase" steps.
Due to their less stable signal, Pseudo Sinus converters are suitable for powering small devices that do not require high starting power, such as various device chargers, GPS units, and lighting.
