Mastervolt Mass Sine Ultra Pure Sine Wave Inverter 24V 4000W

For the toughest tasks

Bringing 4000 W of AC power in a single cabinet, the
Mastervolt Mass Sine Ultra Pure Sine Wave Inverter fulfills even
the highest power needs. Incorporating the ability to use ten units
in parallel or 3×3 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
environmental 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 Mastervolt 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.
