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

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

This model delivers a continuous nominal power output 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 5000W peak capacity enables smooth start-up of highly inductive equipment. This includes devices requiring a high inrush current at start-up, 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 proper operation of sensitive electronic equipment and prevent interference or failures.

The inverter has a robust aluminum chassis. Its dimensions are 420 x 318 x 130 mm (height x width x depth) and it weighs 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 up to 60° from the vertical. It must be installed in a dry, well-ventilated location.

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

Yes, absolutely. Thanks to its massive power reserve and 5000W peak power, it is perfectly suited to handle the startup surges of marine compressors and air conditioning units.

For distances up to 2 meters between the batteries and the inverter, it is recommended to use 2x 50 mm² cables to ensure optimal conductivity and minimize 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 solely for 24V battery banks. If you have a 12V installation, you will need to choose the Mass Sine 12/2000 model.

Yes, for a safe and code-compliant installation, the earth (PE/GND) and neutral (N) wires on the inverter output must be grounded.

To properly and safely secure the DC input cables (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, an automatic power derating occurs to protect internal components from overheating.

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

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 LED indicates 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 from 0.0 to 35.0 V without damage, though it is optimized for a nominal 24 V voltage.

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