Description

With a continuous output of 700 W and a pure sine wave, the Mastervolt AC Master 12/700 inverter converts 12 V DC to 230 V AC to power on board the same equipment you use at home. Suitable for recreational and semi‑professional use: lighting, electric cooking, household appliances and power tools.

The output voltage is selectable between 200 and 240 V at 50 or 60 Hz; efficiency reaches 91%. The built‑in galvanic isolation physically separates the AC circuit from the vessel’s DC system. A variable‑speed fan manages cooling according to load, with automatic derating above 40 °C. Integrated protections cover over‑temperature, overload, short circuit and out‑of‑range battery voltage. Requires a battery of at least 100 Ah, 25 mm² DC cables and a 100 A slow‑blow fuse.

The inverter is compatible with Mastervolt’s MasterBus communication bus and, via the optional AC Master Interface, integrates with the onboard energy control panel for monitoring and remote control. CE and E‑mark certified.

Main features

  • Pure sine wave with 91% efficiency: reliably powers sensitive loads such as appliances, electric motors and electronics that require clean mains power
  • 700 W continuous output maintained up to 40 °C, with active derating above this threshold to protect the unit in hot environments
  • Selectable output voltage from 200 to 240 V at 50/60 Hz, with AC connection via EU Schuko plug (also available in UK or NZ/AU versions)
  • Galvanic isolation between the AC circuit and the vessel’s DC system to reduce interference and galvanic corrosion risks on the electrical installation
  • MasterBus compatibility via the optional AC Master Interface for integration into the Mastervolt onboard energy management system
  • Comprehensive protections against over‑temperature, overload, short circuit and high or low battery voltage, with IP21 rating (protection against vertical drips, suitable for dry interior compartments) for vertical installation
