Mastervolt Mass Sine Ultra Inverter (24V / 4000W / 50Hz)

Description

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.

With an AC capacity of 4000 W in one unit, the Mass Sine Ultra can satisfy even the greatest energy demands. As ten units can be switched in parallel or 3x3 in a three-stage configuration, the Mass Sine Ultra can supply a capacity of up to 40 kW. The inverter provides full power at 40 °C and works smoothly even in extreme conditions such as engine rooms and technical spaces. Like all Mass products, the inverter is supplied in a compact and robust casing. This inverter is the best choice if you are looking for autonomous AC capacity of over 3 kW.
