Střídač Mastervolt Mass Sine 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 peaks up to 4000 W. This peak capacity is ideal for starting complex electrical equipment with high power demand smoothly.

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

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

Idle 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 compatible with MasterBus. 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 analyser.

Absolutely. It includes full protections against overheating, overload, short circuits, as well as abnormally high or low battery voltages.

It must be installed in a closed, properly ventilated compartment, protected from rain, humidity, condensation, and dust. Never cover the ventilation openings to avoid overheating the device.

The LEDs indicate the device's status:

Slow blinking (with "inverter on"): the inverter is overloaded and has entered standby mode before automatically restarting. Fast blinking: 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 complies with IP23 ingress protection standard, protecting it against solid objects larger than 12.5 mm and rainwater up to a 60° angle.

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

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

The converter shuts off automatically 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, an automatic power derating applies 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.
