Mastervolt AC Master Pure Sine Wave Inverter 12/300 230 V

AC Master 12/300 (230 V)

Mastervolt sine wave inverters have proven themselves under the
most extreme conditions for over 25 years. Our inverter family
consists of AC Master, Mass Sine and Mass Sine Ultra models,
ranging from 300 watt up to 40 kW. The AC Master is ideal for small
and medium-sized applications, while Mass Sine and the advanced
Mass Sine Ultra inverters are mainly intended for larger systems
and for professional purposes. 

AC Master series: Reliable AC power for recreational and
semi-professional use

These affordable sine wave inverters convert 12 or 24 V battery
voltage into reliable 230 V 50/60 Hz or 120 V 50/60 Hz grid power,
making them ideal for recreational and semi-professional
applications. The AC Master series is easy to install and delivers
full output, even under the most demanding conditions. The pure
sine wave technology provides an outstanding power quality,
ensuring the correct functioning of sensitive equipment. The usage
of high frequency switching technology eliminates any annoying
humming and buzzing sounds.

Representing complete value for money, these ruggedly built
inverters provide essential home comforts when you’re far from the
nearest grid connection.

Features

• Pure sine wave technology protects sensitive equipment.
• Delivers full output at high peak power under the most
  demanding conditions.
• Automatic power saving system for extended runtime.
• Compact and lightweight design, saving valuable installation
  time.
• Reliable and safe operation; protected against
  over-temperature, overload, short circuit, high or low battery
  voltage.
• Variable speed fan for quiet operation at low power.
• Optional remote control for instant switch off of the inverter
  and all connected equipment (not available for the 300 and 500
  W models).
• Convenient plug connection for all models, 2500/3500 Watt
  models also hard wired. 

In addition, the 2500/3500 Watt models offer:

• Combine 2 up to 15 units to obtain high power or 3-phase
  systems.
• Integrated transfer system, switches automatically between AC
  power sources. 

Applications

Both recreational and semi-professional use, where grid power
varies or is unavailable. Applications include lighting,
appliances, electric cooking and power tools. For (mobile)
applications in your home, office or service vehicle, or during
your holidays.
