Mastervolt Mass Sine 24/2500 Inverter (230V/50Hz)

The Mass Sine 24/2500 converts the 24V DC from your battery bank into 230V AC / 50Hz. It supplies your domestic electrical appliances aboard the boat with high-quality power.

This model delivers a continuous rated power of 2000W at 40°C. It can also provide up to 2500W for a duration of 30 minutes (at 40°C), which is ideal for temporary high loads.

The exceptional peak capacity of 5000W allows for smooth startup of highly inductive equipment. This includes devices requiring a high inrush current at startup, such as electric motors, compressors, or air conditioning systems.

Yes, it generates a pure sine wave (50Hz frequency ± 0.1%). This power quality is essential to ensure the proper operation of sensitive electronic equipment and prevent interference or failures.

The converter has a robust aluminium chassis. Its dimensions are 420 x 318 x 130 mm (height x width x depth) for a weight of 10.1 kg.

The Mass Sine 24/2500 has an IP23 protection rating. It is protected against solid objects larger than 12.5 mm and against water spray at angles up to 60° from the vertical. It must be installed in a dry, well-ventilated location.

To protect your batteries, the converter automatically shuts off if the voltage drops to 19V (±0.5V). It will restart automatically once the voltage rises back to 22V (±0.5V) after recharging.

Yes, exactly. With its massive power reserve and 5000W peak power, it is perfectly suited to handle start-up surges from marine compressors and air conditioning systems.

For a distance up to 2 meters between the batteries and the inverter, it is recommended to use cables with a cross-section of 2x 50 mm² to ensure optimal conductivity and avoid losses.

Yes, it integrates perfectly with the MasterBus ecosystem. To do this, you will need a dedicated interface (such as the MasterBus Converter Interface or the AC Power Analyser) to monitor voltage, current, and charge.

No, this specific model (reference 24022500) is designed exclusively for 24V battery banks. If you have a 12V installation, you will need to choose the Mass Sine 12/2000 model instead.

Yes, for a secure and code-compliant installation, it is mandatory to ground the earth wires (PE/GND) and the neutral (N) at the converter’s output.

To correctly and safely secure the DC input cables coming from the battery, the manufacturer recommends using a 13 mm socket wrench.

The converter is designed to operate within a temperature range of -25°C to 80°C. However, note that above 40°C ambient temperature, a power derating is automatically applied to protect internal components from overheating.

Yes, you can connect a remote control panel. This model is compatible with Masterlink MICC panels or the C-4-RI panel for easy control from the chart table.

The Stand-by mode reduces idle power consumption (to 0.6W) when no load is detected. The load detection threshold for exiting standby is adjustable from 0 to 40W. If consumption is very low, the converter enters standby. It automatically reactivates as soon as a device is powered on.

Absolutely. Unlike lightweight ranges, the Mass Sine series is specifically designed for intensive, prolonged, and demanding operation, meeting the needs of professional and semi-professional vessels.

The High Temperature indicator shows that the inverter is overheating. This typically occurs during prolonged use with very heavy loads or if ventilation around the unit is insufficient.

The converter accepts an absolute input voltage range between 0.0 and 35.0 V without damage, though it is optimized for a nominal voltage of 24V.

Yes, it is equipped with multiple safety features. In case of overload, the Overload indicator lights up. If the overload persists, the inverter will enter safety shutdown to protect both the device and your electrical installation.
