Mastervolt Acculader-Omvormer Mass Combi Ultra 48/3500-50

The new Mass Combi Ultra series is a compact inverter/charger combination with an intelligent switching system, an extremely efficient MPPT solar charge regulator and a separate second charger, all combined in a sturdy, high-quality housing that is easy to install. The Mass Combi Ultra contains revolutionary technology, including the latest V6 high-frequency conversion technology in combination with an extremely fast and powerful DSP control. The new Mass Combi Ultra fits perfectly into a Mastervolt system setup. You can easily connect all components via MasterBus and operate and monitor your installation completely intuitively. This is possible with just one MasterView Easy touchscreen. On this touchscreen you can read all information from the Combi, the batteries and other sources such as generator, grid power or solar panels and you can control the operation. The system is also suitable for Digital Switching, Mastervolt’s decentralised digital switching system. On the DC side, the Mass Combi Ultra has interesting features such as a solar input with a super-efficient, integrated MPPT solar charge regulator and an independent second charger output, which in most cases can charge both 12V and 24V batteries. The Mass Combi Ultra has two separate AC inputs for generator or mains power, both adapted to the specific characteristics of each power source. Thanks to the super-fast control, the transition to and from the inverter is seamless and users enjoy uninterrupted power without flickering or failure of sensitive equipment. The Mass Combi Ultra not only offers ‘stand-alone’ functionality but also parallel use and 3-phase operation for larger applications up to 35 kW.

The Mass Combi Ultra series consists of various models, ranging from 3000 to 3500 Watt. For higher capacities up to 35 kW, the Combi Ultra can be connected in parallel or 3-phase configuration. An efficient integrated solar charge controller gets the most out of your solar panels.

The Mass Combi Ultra is equipped with the latest technology. The new ‘V6’ inverter technology ensures low no-load consumption and the ultra-fast Digital Signal Processor ensures seamless switching between all available energy sources. With Power Assist, voltage dips and power failures are a thing of the past, even with a weak electricity connection or small generator. In addition, all Mass Combi Ultra models are equipped with MasterBus.
Higher yield from solar energy

Mastervolt has used its experience in grid-connected solar solutions to develop a super-efficient, integrated MPPT solar charge controller. Compared to regular solar charge controllers, the advanced MPPT technology achieves up to 30% more yield from the solar panels. The solar panels supply hidden consumers with energy and keep your batteries in optimal condition.
Silent operation

The Combi Ultra can supply up to 50% of the charging current or inverter capacity without fan cooling. This is ideal during night-time hours; if little power is consumed, the fan will not turn and the Combi will operate silently. If maximum power is required or when it is very warm around the Combi, the Active Optima Cooling concept regulates the fan speed linearly, so that it never unnecessarily turns too fast or makes a ‘ticking’ sound.
Exceptional performance

The inverter is silent, clean and efficient. Even at extreme ambient temperatures, the full capacity is available. Pure sine wave voltage and a peak power of 200% guarantee a problem-free start of even the heaviest consumers.
Optimal use of your batteries

The powerful battery charger charges two battery banks simultaneously and delivers full charging current up to 40 °C ambient temperature. Precise charging characteristics and low ripple current guarantee a long service life of your batteries. The 24 V version can combine 12 V and 24 V battery sets.
