Konverter Mastervolt Mass Sine 24/1500 (230V/50Hz)

The Mass Sine 24/1500 inverter delivers a continuous power output of 1200 W at an ambient temperature of 40°C, with a power factor (cos phi) of 1. It can also provide a power output of 1500 W in P30 mode at 40°C, and a peak power of 2900 W for starting demanding equipment.

The Mass Sine 24/1500 produces a pure sine wave output (true sine). This ensures high-quality power supply, compatible with all sensitive electronic devices, without risk of malfunction or damage.

The nominal input voltage of this converter is 24 V DC (direct current). It is designed to be powered by a 24 V battery.

The output voltage is 230 V AC (± 5 %) with a frequency of 50 Hz (± 0.01 Hz). This stability ensures reliable operation of your equipment.

In normal mode (ON), idle consumption is approximately 200 mA (5 W). In energy-saving mode (Low Energy Mode), it drops to 25 mA (0.6 W), preserving the battery during long periods of inactivity.

The inverter includes multiple protections to ensure safe operation:

Overload protectionShort-circuit protectionOverheat protectionHigh and low battery voltage protection

The Mass Sine 24/1500’s maximum efficiency is 92 %. Thanks to its high-frequency switching technology, energy losses are minimized, reducing heat dissipation and optimizing battery autonomy.

The Mass Sine 24/1500 can operate within an ambient temperature range of -25 °C to 80 °C. Above 40 °C, the available power decreases progressively (thermal derating).

The protection rating is IP23. This means it is protected against solid objects larger than 12 mm (fingers) and against water jets at angles up to 60° from the vertical. It must be installed in a dry, ventilated space, protected from rain and direct spray.

The housing dimensions are as follows: height 340 mm, width 261 mm, depth 130 mm.

No, this model is specifically designed for a nominal input voltage of 24 V. Using it with a 12 V battery would not allow correct operation and could damage the device. For a 12 V installation, other models are available in the Mass Sine range, such as the 12/1200 or 12/2000.

For safe installation, Mastervolt recommends:

Minimum DC cable section: 25 mm²Minimum DC fuse (slow blow): 100 AThese values allow handling the nominal input current of 68 A and provide effective protection for the wiring.

Yes, the inverter is compatible with Mastervolt’s MasterBus network. To do this, it requires the use of a MasterBus Converter Interface or an AC Power Analyzer. This enables remote monitoring, control, and integration into a larger system (for example, with an EasyView 5 or a C4-RI control panel).

Yes, the Mass Sine 24/1500 can be integrated into a CZone system via the MasterBus interface. Mastervolt provides specific configuration instructions to enable control and monitoring of the inverter from CZone displays.

Several remote control options are available:

Remote control panel C4-RIEasyView 5 (via the MasterBus network)Masterswitch / Systemswitch for automatic power source selection

The identification plate is located on the right side of the Mass Sine housing. It contains essential technical data (serial number, references, voltages, etc.) required for after-sales service, maintenance, and ordering spare parts. It must never be removed.

Installation must be performed by a qualified electrician in compliance with local regulations. Key steps:

Install the unit in a ventilated, dry, and weather-protected location.Use DC cables with a minimum cross-section of 25 mm².Place a 100 A slow-blow fuse on the positive cable between the battery and the inverter.Do not connect the AC output to another voltage source (mains, generator).Respect polarity to avoid damaging the unit (reverse polarity is not covered by the warranty).

Mastervolt recommends using a battery with a capacity greater than 150 Ah to properly power the Mass Sine 24/1500. A battery with sufficient capacity ensures the 68 A rated input current is supplied without excessive strain and optimizes autonomy.
