Mastervolt Mass Combi Pro inverter charger 24/3500/100 230V

The Mastervolt Mass Combi Pro 24/3500/100 230V inverter provides a continuous output of 3500 W, even at an ambient temperature of 40 °C (cos phi = 1). It can also handle a peak power of 7000 W.

The Mass Combi Pro inverter delivers a pure sine wave. The total harmonic distortion (THD) is less than 1% under standard conditions.

The Mass Combi Pro integrates a 3-stage+ smart battery charger (IUoUo) with a maximum charge current of 100 A. It is compatible with a wide range of battery types.

Yes, the Mass Combi Pro has dual AC inputs. It can connect to a generator source (50 A) and a shore power supply (30 A), ensuring seamless switching between them.

The Power Assist function allows the Mass Combi Pro to supplement AC input with battery power when the load demand exceeds the capacity of the external AC source (generator or shore power). This prevents power cuts and enables the use of lower-power AC sources.

The Mass Combi Pro is designed to operate within an ambient temperature range of -25 °C to 60 °C. It is important to note that a power reduction (derating) may occur above 40 °C.

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

During charging, the LEDs indicate the charging current (20% of the rated current per LED). During inversion, they indicate the inverter's power output (20% of the rated power per LED). If the top LED lights up red, the inverter is overloaded. They also provide an estimate of the battery voltage during inversion: the more LEDs that are lit, the higher the battery voltage.

For the 24V model, the acceptable DC input voltage range is 19 V to 32 V.

Yes, the nominal AC output voltage is 230 V (±2%), but it is configurable from 180 V to 260 V.

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

The Mass Combi Pro is designed for indoor use only. It must be installed in a location where the ambient temperature is between -25 °C and 60 °C. A maximum installation height of 2000 m is specified.

Yes, at least 150 mm of free space below the Mass Combi Pro is required to facilitate installation and access to the DIP switches.

Keep cables as short as possible to maximize system efficiency.Use the minimum recommended cable lengths.Run positive and negative cables side by side to limit electromagnetic field.Connect the negative cable directly to the negative terminal of the battery bank or to the load side of a current shunt.Do not use the vessel’s chassis as a negative conductor.Run the battery positive cable through a fuse and connect it to the positive terminal of the battery bank.Fuse rating depends on the cable size used.Tighten DC connections securely (15–20 Nm / 130–175 in-lbs).

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

The Mass Combi Pro must be grounded using an equipment grounding conductor connected to the AC input earth terminal. Grounding and all other wiring must comply with local rules and regulations.
