Mastervolt AC Master 12/700 12V 230V

Convert 12V Battery Power into 230V Pure Sine Wave AC

The Mastervolt AC Master 12/700 inverter converts 12V DC battery power into high-quality AC electricity, with a selectable output voltage of 200V, 220V, 230V or 240V at 50Hz or 60Hz.

Its pure sine wave output provides a stable waveform suitable for a wide range of electrical appliances and sensitive electronic devices when shore power or mains electricity is unavailable.

With 700W of continuous output power, the AC Master 12/700 is well suited to autonomous electrical systems on boats, camper vans, recreational vehicles and other battery-powered installations.

700W Continuous Power with High Peak Capacity

The inverter delivers 700W continuously, including at an ambient temperature of 40°C.

It can also handle short-term peak loads:

• Peak power for 1 minute: less than 810W
• Peak power for 1 second: less than 1,230W

This temporary overload capacity can help when powering equipment with a higher initial start-up current than its normal operating consumption.

Pure Sine Wave Output for Sensitive Electronics

The pure sine wave output, with typical harmonic distortion below 3%, provides stable AC power suitable for many sensitive electrical devices.

This makes the inverter particularly useful for electronics such as computers, displays, chargers, audio systems and onboard electronic equipment, provided their total power requirements remain within the inverter’s operating limits.

High Efficiency and Energy-Saving Mode

With an efficiency of up to 91%, the Mastervolt AC Master 12/700 helps reduce energy losses during DC-to-AC conversion.

No-load consumption is below 1.5A during normal operation and drops below 0.1A when the energy-saving mode is active.

Designed for Marine and Mobile Installations

Compact and lightweight, the AC Master 12/700 measures approximately 200 × 330 × 83 mm and weighs around 2.7 kg.

Its cooling fan is automatically controlled according to temperature and load, helping optimise cooling performance during operation.

With an IP21 protection rating, the inverter is designed for installation in a protected indoor location and should be horizontally wall-mounted in accordance with the manufacturer’s installation instructions.
