Mastervolt MASS Combi Ultra 12v/3000w/150A Invterter/Charger

The new standard in power systems

Mastervolt, the Dutch leader in off-grid electrical systems, has unveiled an innovative new Mass Combi Ultra series. This compact inverter/charger combination with a smart transfer system, highly efficient MPPT solar charge regulator (available from October 2014 onwards) and separate second charger is all enclosed within a robust quality unit that is easy to install.

Following the ever-increasing demand for higher power and greater comfort, systems are becoming more and more complex. In response the Mastervolt team went back to the drawing board to redesign what was already the best product in the market. Our goal was to fulfil the requirements of today and tomorrow, which the Mass Combi Ultra achieves by integrating all the common needs of an electrical system. This simplifies installation, lowers overall costs and significantly increases performance.

The latest technologies

The Mass Combi Ultra includes revolutionary technology developed by Mastervolt’s own engineering team. Notable achievements include combining the latest V6 high frequency converter technology with ultra-fast and powerful DSP controls. This offers major user benefits such as a low ‘no load’ current, preventing your batteries from draining, and extreme peak power capability which allows high current loads such as air conditioning to start-up easily without power dips or light flickering. Another benefit is the high efficiency, which makes the Mass Combi Ultra the most complete product in its class.

Mass Combi Ultra in a Mastervolt system

The new Mass Combi Ultra fits perfectly into Mastervolt systems. All components are easily connected via MasterBus and installation can be controlled and monitored intuitively, even with just one MasterView Easy touchscreen. This will provide and manage all information about the Combi, the batteries and other sources such as the generator, grid or solar panels. The system is also suitable for Digital Switching, Mastervolt’s decentralised digital switching system.
