Sinusoidni pretvornik Mass Sine Ultra 24/4000

It delivers a continuous power output of 4000 W, even at an ambient temperature up to 40 °C, with no loss of efficiency.

Peak power reaches 7000 W. This energy reserve is ideal for smooth starts of complex, high-energy equipment such as air conditioning compressors or large electric motors.

It generates a pure sine wave alternating current (True Sine Wave) at 230 V with a total harmonic distortion (THD) below 1%. This ensures a perfectly stable and safe power supply for your most sensitive electronic equipment.

The device has the following physical specifications:

Height: 472 mmWidth: 318 mmDepth: 178 mmWeight: 15 kg

It is designed to operate with a 24 V DC battery bank. Its input voltage range is programmable and spans from 19 V to 32 V to accommodate different battery types.

Yes, thanks to its modular architecture and dedicated Sync ports, you can couple up to 10 units in parallel to multiply the overall output power of your electrical system.

Absolutely, the Mass Sine Ultra supports complex three-phase configurations. You can integrate up to 9 units (3x3 configuration) to meet the needs of large-scale marine installations.

For optimal operation, use a battery bank with a capacity greater than 350 Ah.

To ensure system safety and efficiency, use DC cables with a minimum cross-section of 70 mm², always paired with a 250 A inline fuse.

No, its standby consumption is very well controlled to preserve your batteries:

16 W in normal operation7 W in energy-saving mode4 W in remote stop mode

Yes, it is fully compatible. It features two MasterBus ports, enabling monitoring, configuration, and precise control of your installation via a MasterView display or a PC running the MasterAdjust software.

It has an IP23 ingress protection rating. This means it is protected against finger contact and water spray at angles up to 60 degrees from the vertical. It is designed exclusively for indoor installation.

It operates optimally between -25 °C and 60 °C. Note that a preventive power reduction (derating) is automatically applied when the ambient temperature exceeds 40 °C to protect internal components.

The Mass Sine Ultra 24/4000 complies with the strictest marine and mobile sector safety standards. It holds international certifications CE, ABYC, and E-mark.

Yes, it is essential to leave at least 150 mm of free space below the converter. This allows for easier cable routing, access to the DIP switches, and ensures adequate ventilation to prevent hot air buildup.

Yes, the output frequency is selectable between 50 Hz and 60 Hz (±0.005%). This setting can be easily adjusted via the MasterBus network.

Yes, the front panel is equipped with a practical display panel featuring:

LED indicators showing power draw (in 20% increments)Battery charge statusAC output indicatorMain power On/Off switch

The device includes full automatic protections. It is protected against short circuits, overloads (indicated by a red LED on the front panel) and excessive internal temperatures. In case of a critical fault, the inverter switches to safety mode to prevent any damage.

The Mass Sine Ultra 24/4000 delivers excellent energy efficiency with a maximum efficiency of 92% or higher. This helps preserve your battery bank's autonomy and minimizes energy loss as heat.

Yes, for a secure installation fully compliant with local electrical regulations, it is mandatory to connect the AC output neutral conductor (N) to the ground (PE / GND) of your vessel or vehicle.
