Mass Combi Ultra 12/3000-150 Charger Converter

It is an all-in-one energy management center for marine and mobile systems. It combines:

A 3000 W pure sine wave inverterA 150 A battery chargerA solar charge controller with MPPTAn intelligent AC transfer system

The inverter delivers a continuous power output of 3000 W (maintained even at 40 °C) and can provide a peak power of up to 6000 W to start highly demanding equipment such as air conditioning or compressors.

Yes, the Ultra version features an integrated MPPT solar charge controller. This allows you to connect your photovoltaic panels directly to the device without needing an external regulator.

The dedicated solar input can handle up to 375 Wp of photovoltaic panels, with a maximum open-circuit input voltage (Voc) of 100 V and a maximum power (Pmpp) of 300 W.

The charger is highly versatile. It is compatible with 12V battery banks of the following types:

Flooded lead-acidGelAGMSpiral-woundLithium-ion

Yes. It features a secondary 10 A charge output, specifically designed to maintain the charge of a small battery such as a starter battery. This output is intended for 12 V batteries.

The Power Assist function is designed to prevent tripping a shore power connection or a low-power generator. In case of a power spike, the device instantly draws the missing energy from the batteries to compensate.

The Mass Combi Ultra has:

Two independent AC inputs (shore power and generator) with automatic switching. Two AC outputs (Out-1 and Out-2) for power distribution.

Output management is intelligent:

Out-1: This is an uninterrupted output that continuously powers your critical devices. Out-2: This is a secondary output that automatically shuts off when no external AC source (shore power or generator) is available, to preserve your battery energy.

Yes, to meet very high power requirements, you can install up to 10 Mass Combi Ultra units in parallel configuration.

Yes. Up to 9 units can be configured (3 x 3) to create a complete and robust 400 V AC three-phase network.

To ensure optimal performance and safety in a 12V system, use a minimum DC cable cross-section of 95 mm² with an inline fuse rated at 350 A. Keep cables as short as possible.

No, it has an IP23 protection rating. It is protected against contact with fingers and water sprayed at less than 60 degrees from the vertical. It is designed for indoor installation only.

The charger inverter is designed in a compact housing measuring 472 mm in height, 318 mm in width and 178 mm in depth. Its total weight is 15.3 kg.

The device is designed to operate in ambient temperatures ranging from -25 °C to 60 °C. It maintains its continuous power output of 3000 W up to 40 °C. Beyond this temperature, a power derating (derating) is applied to protect internal components.

Yes, the integrated inverter provides pure sine wave voltage (230 V, 50/60 Hz). This ensures flawless operation, high efficiency, and prevents damage to sensitive electronic devices (such as computers or adapters).

The transfer is fully automatic. As soon as an external AC source (such as shore power or a generator) is detected and validated, the device switches from the inverter to the external source without any perceptible interruption to your equipment.

Configuration and monitoring are straightforward using its two MasterBus ports. You can connect it to compatible Mastervolt displays or use the free MasterAdjust software on a PC via a MasterBus USB interface.

The charger section delivers a massive 150 A output. Combined with the 3-stage+ smart charging process, it ensures extremely fast recharging and optimizes the lifespan of your 12 V battery bank.

Yes, the Mass Combi Ultra meets the strictest industry safety and quality standards. It holds CE, ABYC, E-mark, and RMRS certifications, ensuring absolute reliability for marine and mobile professional use.
