The Mastervolt transfer system helps you regulate your grid, generator or inverter power and automatically selects the right power sources at the right time. This automatic switching system, when combined with an IVET transformer, can adjust shore power to suit the onboard system. As a result a 230 V/50 Hz system can operate with an American or Caribbean shore connection. You must still ensure that the frequency on board (50 of 60 Hz) is the same as the frequency of the incoming current. The switch prevents damaging contact between the inverter and other 230V sources, and, as well as being fully compatible with Mastervolt systems, is suitable for installations from other brands, other generators and/or inverters.
