Mastervolt Mass Combi Ultra 12 Volt 3000 Watt 150 Amp 38013000
Mastervolt Battery Mass Combi Ultra The new Mastervolt Mass Combi Ultra combines an inverter and battery charger into one compact, easy to install, robust package. Built-in functions within the intelligent transfer system include seamless switching between generator and grid, inclusion of a secondary charger plus parallel and three phase operation. Designed to meet the ever increasing power demands of today’s modern vessel, the Mass Combi Ultra integrates common requirements for an onboard electrical system to significantly increase performance and help lower overall costs while providing simple, compact installation. To achieve major improvements and efficiencies over current market products, Mastervolt combined the latest V6 high frequency converter technology with ultra fast and powerful digital signal processor controls. Practical user benefits from such innovations include low no load current which helps prevent batteries from draining, plus an extreme peak power capability which allows high current loads such as air conditioning compressors to start up easily without power dips or interference to lights. For complete versatility and control, the Mass Combi Ultra has been designed and engineered to slot seamlessly into Mastervolt and C-Zone systems. All components are easily connected via MasterBus and installation can be controlled and monitored intuitively, even via a single 110/660 MasterView Easy touch screen. The touch screen allows management of all Combi information, batteries and other sources such as generator and grid. As always, Mastervolt has designed and engineered the Mass Combi Ultra units with carefully thought out connections optimised for electricians to IP23 vertical position. The logical connection layout, solid terminals and removing the need for cable glands ensure quick and easy installation. To ensure minimal cooling fan use and whisper quiet operation, the units employ Mastervolt’s Active Optima Cooling concept. The advanced thermal design provides optimal performance and quiet operation when required, with the ability to provide up to 50% of the charging current or inverter capacity without fan cooling. Additionally, the smart Active Optima Cooling concept regulates the fan speed in a linear way when maximum capacity is required or ambient temperatures are very high. Two separate AC inputs for the generator and shore power are provided as standard, both adjusted to the specific characteristics of each power source. Ultra fast controls result in seamless transfer to and from the inverter ensuring continuous power without interference or the risk of sensitive devices like computers being switched off. Additionally, the unit’s stand alone operation combined with functionality and flexibility allows parallel and three phase operation for larger applications up to 35 kilowatts. For optimal battery usage, maximum power and battery lifespan, the Mass Combi Ultra units provide pure interference free direct current voltage that prevents unnecessary heating of the batteries. A low no load current that guarantees every ampere hour is deployed in the most optimal way helps to ensure maximum battery efficiency. For simplified installation and cost reduction to the end user, Mastervolt has also integrated a second battery charger in each model which in most cases is capable of charging both 12 Volt and 24 Volt batteries. As an example of power and performance, the 110484 (19-32 Volt) can provide continuous inverter power of 3,500 Watt at 40°C with a peak power of 7,000 Watt. Additionally, for fast charging of the main battery, the powerful integrated battery charger is able to produce 100 Ampere at full charge voltage. Separate AC outputs are included: one permanently powered to supply critical loads such as refrigerators and audio systems; the other output is for non-preferential loads such as water heaters and washing machines that can be switched off automatically at any desired setting to the benefit of the critical loads.

Boat Hut Insight
When choosing an inverter/charger combo like the Mastervolt Mass Combi Ultra, consider how often your vessel runs high surge loads such as air conditioning compressors or electric winches. The Mass Combi Ultra’s extreme peak power capability is a real bonus here, preventing annoying power dips that could cause sensitive electronics to reset. Also, the inclusion of a secondary charger that can handle both 12 Volt and 24 Volt batteries is a clever touch, giving you flexibility for future upgrades or mixed battery banks. One tip for installers and boat owners alike: the logical, electrician-friendly connection layout and removal of cable glands speed up installation and reduce errors. This can save you both time and money during setup. And a little humour for the savvy boatie: if your vessel’s power system was a party, the Mass Combi Ultra would be the smooth operator making sure the lights never flicker and the music never stops—even when the generator takes a break!
