Sine wave inverter, mass sine wave, 12/2000 (230V/50Hz)

This is a pure sine wave inverter that converts the 12V DC from your battery bank into 230V AC (50Hz). It is designed to provide a stable and reliable power supply for sensitive electrical equipment, even in the most demanding marine environments.

The Mass Sine 12/2000 delivers a continuous power output of 1800 W at an ambient temperature of 40 °C, and a 30-minute power output (P30) of 2000 W.

It can absorb very high startup surges up to 4000 W. This peak capacity is ideal for starting complex electrical equipment with high power demand without jerky operation.

For optimal and safe operation of the Mass Sine 12/2000, it is recommended to use a 12V battery bank with a capacity greater than 200 Ah.

Installation requires a 250 A DC fuse (slow-blow type) to effectively protect the wiring between the inverter and the battery.

It is essential to use cables with a minimum cross-section of 70 mm² to connect the converter to your 12V battery bank to prevent overheating or voltage drop.

No, thanks to its high-frequency switching technology, the inverter delivers a high efficiency of 92% while avoiding annoying electrical humming and buzzing.

Standby power consumption is very low. It is 480 mA (6 W) in normal mode and drops to just 50 mA (0.6 W) when in power-saving mode.

Yes, the Mass Sine is MasterBus-compatible. To integrate it into the network and control it via a display (such as the EasyView 5), you must use a MasterBus Inverter interface or an AC power analyzer.

Yes. It includes full protection against overheating, overload, short circuits, and abnormally high or low battery voltages.

It must be installed in an enclosed, properly ventilated space, protected from rain, humidity, condensation, and dust. Never cover the ventilation openings to prevent overheating of the device.

The LEDs indicate the device's status:

- Slow flashing (with "inverter on"): the inverter is overloaded and has entered standby before automatically restarting.

- Fast flashing: the device has shut down completely after multiple attempts and requires a manual restart via the switch.

The converter has the following physical characteristics:

- Dimensions: 420 x 318 x 130 mm (Height x Width x Depth)

- Weight: 14.6 kg

The converter meets the IP23 ingress protection standard, protecting it against solid objects larger than 12.5 mm and rainwater at angles up to 60°.

No, you must never connect the AC (alternating current) output of the inverter to an incoming AC source such as a generator or shore power, as this can cause serious damage.

Yes, Mastervolt Masterswitch and Systemswitch switching systems can be connected to this converter to enable automatic selection of the desired power source.

The converter automatically shuts off if battery voltage drops to 10 V (± 0.5 V) to prevent deep discharge. It restarts automatically when voltage rises back to 11 V (± 0.5 V).

The converter can operate within an ambient temperature range from -25 °C to 80 °C. However, a power derating applies automatically for temperatures above 40 °C.

Yes, the Mass Sine must be equipped with a ground conductor connected to the AC outlet’s ground terminal, in compliance with local electrical codes to ensure installation safety.
