Mass Combi Pro inverter charger 12/3000/150 230 V

The Mastervolt Mass Combi Pro is a complete energy conversion solution. It integrates an inverter, a battery charger, and an AC transfer switch, providing standalone power management for demanding marine and mobile applications.

The inverter delivers a continuous power output of 3000 W at an ambient temperature of 40 °C (with a power factor of 1).

The integrated battery charger delivers a maximum charging current of 150 A at 14.25 V.

It uses a fully automatic 3-step+ charging system (IUoUo) designed to optimize battery charging and lifespan.

Yes, the AC output frequency is configurable for 50 or 60 Hz, with an accuracy of ± 0.005%.

Yes, it has two separate AC outputs:

Output 1 (OUT-1): The AC power is always available on this output, making it ideal for loads requiring continuous power. Output 2 (OUT-2): This output is switched and only available when external AC power (from the grid or a generator) is present. Its policy is configurable.

The Power Sharing function limits the AC input current from the grid or a generator. This prevents overloading the external source. Any unused energy from the AC outputs is redirected to charge the batteries. If the total load exceeds the limited AC input, the inverter supplies the necessary additional power from the batteries.

The nominal DC input voltage is 12 V, with an operating range from 9.5 V to 16 V.

The device dimensions are 472 mm (height) x 318 mm (width) x 178 mm (depth). Its weight is 15.3 kg.

The Mass Combi Pro includes multiple protections to ensure system safety and reliability:

Inverter overload protection.Internal temperature protection.Low or high battery voltage protection.Battery temperature out-of-range protection.AC input frequency and voltage monitoring.

The device is designed to operate within an ambient temperature range of -25 °C to 60 °C. However, power reduction (derating) is applied above 40 °C.

The Mass Combi Pro has an IP23 protection rating. This means it is protected against finger contact and water ingress up to 60 degrees from the vertical.

During inverter mode, the LEDs provide an approximate estimate of battery voltage (the more LEDs lit, the higher the voltage) and inverter power output (each LED represents 20% of nominal power). If the top LED lights up red, this indicates an inverter overload.

The Mass Combi Pro is designed for indoor use only. Installation must be carried out in an area where ambient temperature is between -25 °C and 60 °C, with power reduction above 40 °C.

For optimal efficiency, DC cables should be as short as possible and of the minimum recommended cross-section. It is advisable to route the positive and negative cables side by side to minimize the electromagnetic field. The negative cable must be connected directly to the negative terminal of the battery bank or to the load side of a current shunt. The positive cable must be fused and connected to the positive terminal of the battery bank. DC connections must be tightened securely (15–20 Nm).

Yes, for safe installation compliant with local regulations, residual current devices (RCDs) must be integrated into the AC inputs and AC outputs of the Mass Combi Pro.

It is recommended to allow at least 150 mm of free space below the Mass Combi Pro. This is necessary to facilitate installation and access to the DIP switches.

A minimum recommended toolkit includes a 13 mm socket wrench for securing DC input cables (battery).

Yes, the Mass Combi Pro is a MasterBus-compatible device. It features two data ports to connect to a local MasterBus network, enabling monitoring, configuration, and communication with other Mastervolt devices.

The AC input voltage range for the integrated battery charger is 184 V to 275 V.
