Sinus Inverter

The inverter has two connection points: one for attaching the batterie´s plus- and minus cables and the other for 230 V instruments. All models can be equipped with standard or more advanced control panels.

These inverters still work at temperatures of 40°C (e.g.at the Mediterranean Sea) when simple inverters just have a low efficiency.

The use of AC appliances for onboard comfort has become widespread in the sailing world. As appliances become even cheaper, an inverter is a very sound investment. You must ensure, however, that you choose a long-lasting inverter with a pure sine wave output. Mastervolt inverters feature a long life span and are fully protected against short circuiting, overloading and high operating temperatures. 

The Mass Sinus-Series is equipped with an energy-saving mode, which maintains a high output with partial loads and almost switches off in the standby mode, thus using  up virtually no energy from the battery but still supplying AC power. There are four levels of energy saving modes:
1. Inverter switched off: with the remote control panel or the on/off switch at the instrument.
2. Inverter Stand-by-/ wait mode: minimal battery consumption, yet still supplying energy for small appliances. Switches automatically
3. Inverter on: supplying current from battery as required for connected 230 V appliances. Energy consumption is 2 W for small models and 6 W for heavy duty units.
4. There is an extra "low energy mode", for reducing the basic consumption by 10%. This is especially useful for small battery systems with a solar panel. 

Many AC appliances need an extra surge of energy for starting, especially inductive appliances such as fridges, vacuum cleaners, dishwashers, TV´s and some tools. Mastervolt inverters can easily cope with the required power surge.

Installing the inverter, you should be aware of the following points: tighten all connections properly; connect  Plus to Plus and Minus to Minus. 
DC output: the easiest way is to connect the AC instrument directly to the inverter output.

At an Ohm resistive load the capacity specifications in VA correspond to the capacity specifications in W.

An inverter should be placed as close to the service battery as possible, to avoid voltage loss in the cables. It is often built-in somewhere (always ensure sufficient ventilation for cooling) and difficult to reach for switching on/off or maintenance. For this reason Mastervolt has developed a Remote control panel - the C4-RI – featuring these functions: Inverter on/off, "on" indicator, "fault" indicator. Possible faults include e.g. battery voltage too low, (accidental) overload( causes no damage at the instrument), or a short circuit in the 230 V cable.   Remote control C4-RI 10m connection cable
