Even in extreme conditions, Mass series products operate without interruption, at full power for 24 continuous hours if necessary. With an MTBF of 180,000 hours at full power in 24/7 use, the Mastervolt Mass Sine 12/2000 is ideal for the most demanding applications and any situation requiring reliable, continuous power. Mastervolt Mass Sine inverters have proven their worth in extreme conditions for 30 years.
Optimal Flexibility for the Electrical System
Choosing an independent pure sine wave inverter allows maximum freedom in choosing the type of battery charger. Depending on charging time requirements, you can freely choose the appropriate charger, even with a renewable source via an MPPT solar charge controller.
High Efficiency
High efficiency and automatic economy mode are designed to properly run digital clocks and make batteries last longer. Switching technology eliminates hum and provides high inrush currents to power electric tools without interruption.
Clear Indicators and Remote Control
The Mass Sine features clear, simple front-panel controls. A C4-RI remote control is available for installations in hard-to-reach locations. It can also be controlled from the EasyView 5 display via MasterBus, using a MasterBus Inverter interface or AC Power Analyser.
