Mastervolt Mass Sine 122000 (120 V)

The Mass Sine inverters are mainly intended for larger systems on superyachts and for (semi-)professional purposes. Mastervolt offers inverters for 230 V/50 Hz as well as 120 V/60 Hz (American voltage).

Proven technology
Mastervoltâ€™s Mass sine wave inverters have proven themselves in the most extreme conditions for over ten years. Although the dimensions and connections of the various models have remained the same, the technology has evolved with the times, resulting in a fast, efficient, one-on-one replacement with minimal downtime.
