Sinusoidni pretvornik Mass Sine 12/2000 (230V/50Hz)

This is a pure sine wave inverter that converts the 12V DC voltage from your battery bank into 230V AC (50Hz) power. 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 handle very high startup surges up to 4000 W. This peak capacity is ideal for starting complex, high-power electrical equipment smoothly.

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

The 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 inverter to your 12V battery bank in order to prevent overheating or voltage drop.

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

Absolutely. It includes full protections against overheating, overload, short circuits, as well as 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 status:

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

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

The inverter has the following physical specifications:

Dimensions: 420 x 318 x 130 mm (Height x Width x Depth)Weight: 14.6 kg

The converter meets IP23 ingress protection standards, protecting it against solid objects over 12.5 mm and water spray up to a 60° angle.

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

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

The inverter automatically shuts down 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 inverter 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 grounding conductor connected to the AC output earth terminal, in compliance with local electrical standards to ensure installation safety.
