Mastervolt Mass Sine Inverter (12V / 2000W / 50Hz)

The Mastervolt Mass Sine power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. It is compatible with the Mastervolt MasterBus system, allowing it to be connected and configured centrally on the EasyView 5 alongside other items in your electrical system. It can also be operated by the remote panel, or on the device itself.

The power inverter can give you consistent, 24/7 use, with an MTBF (Mean Time Between Failures) of 180,000 hours when at full capacity without stopping. The Mass Sine range are extremely efficient and also feature an automatic economy mode, allowing digital clocks to carry on working whilst not putting excess strain on the battery. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming.
