Mass Sine Ultra 24/4000

Mastervolt offers a complete range of inverters from 300 watt to 40 kwatt in AC Master, Mass Sine and Mass Sine Ultra models. The AC Master is ideal for small and medium-sized applications, while Mass Sine and the advanced Mass Sine Ultra inverters are mainly intended for larger systems and for professional purposes. Mastervolt offers inverters for 230V/50Hz as well as 120V/60Hz (American voltage).

Ultra high power

Bringing 4000 W of AC power in a single cabinet, the Mass Sine Ultra inverter fulfills even the highest power needs. Incorporating the ability to use ten units in parallel or 3x3 in 3-phase configuration, the Mass Sine Ultra is able to supply loads of up to 40 kW*. Providing continuous full power at 40 °C, it works effortlessly under even the harshest environment conditions as you will typically find in an engine or technical room. As with all Mass products, this inverter comes in a rugged chassis and is even more compact than the Mass Sine range. When you are in need of autonomous AC power in excess of 3 kW, this is your inverter of choice.

The latest technology

The Mass Sine Ultra design is based on over 20 years experience with the Mass Sine range, using the latest technology in power electronics and digital control. Its highly efficient V6 high frequency power electronics allow for very high power density, saving both weight and volume, bringing silent operation and extremely low battery current ripple, extending the life of your batteries. The latest and fastest in digital signal processing prevents nuisances like flickering and dips. 

Get the most out of your batteries

The Mass Sine Ultra incorporates a dynamic battery voltage window. Taking into account the battery type as well as the current that is being drawn from the battery, it automatically adapts the battery voltage at which the Mass Sine Ultra will stop drawing power from the batteries. The dynamic battery voltage window allows you to enjoy AC power for a longer time, without mistreating your batteries. 

Optimal flexibility in system design

Choosing an independent sine wave inverter as the Mass Sine Ultra, allows you complete freedom of choice of battery charging equipment. In case you want to use renewable energy sources, you may want to choose an MPPT solar charge regulator and combine it with a wide range of Mastervolt AC and  DC chargers. You can freely adapt the rating of these chargers, depending on the desired charge time.

MasterBus integration

Once you have selected your ideal system, including the Mass Sine Ultra, it can be configured, controlled and monitored from a single screen. This is possible by the integration of MasterBus communication, which at the same time allows the individual products in a system to cooperate and optimize the overall operation of the system.
