Convertor 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 (pure 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 %) at a frequency of 50 Hz (± 0.01 Hz). This stability ensures reliable operation of your equipment.

In normal mode (ON), standby power consumption is approximately 200 mA (5 W). In low energy mode (Low Energy Mode), it drops to 25 mA (0.6 W), which helps preserve the battery during long periods of inactivity.

The converter includes multiple protections to ensure safe operation:

Overload protectionShort-circuit protectionOverheat protectionHigh and low battery voltage protection

The maximum efficiency of the Mass Sine 24/1500 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 gradually (thermal derating).

The ingress 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 direct rain and spray.

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

Yes, the converter is compatible with the MasterBus network from Mastervolt. For this, it requires the use of a MasterBus Converter Interface or an AC Power Analyzer. This allows 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.

Multiple remote control options are available:

C4-RIEasyView 5 remote control panel (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 carried out by a qualified electrician in compliance with local regulations. Here are the key steps:

Install the device 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 device (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 allows it to supply the nominal input current of 68 A without excessive strain and to optimize autonomy.
