Power your off-grid adventures or professional installations with the Mastervolt AC Master 12/2000 Inverter. This 12V input model converts battery power into clean, grid-quality 120V AC, delivering dependable 2000W continuous output with impressive peak capabilities. Its compact, lightweight design simplifies installation, while advanced protections keep both inverter and connected equipment safe and reliable.

• True sine wave technology protects sensitive devices and ensures smooth operation for electronics, chargers, and audio/video gear.
• High peak power capability: < 2300 W for 1 minute and < 3500 W for 1 second to handle surge demands.
• Automatic power saving system extends runtime by reducing consumption when loads are light.
• Compact & lightweight design saves space and speeds up installation in vehicles, boats, or homes.
• Robust protections against over-temperature, overload, short circuit, and high/low battery voltage for safer operation.
• Quiet cooling with a variable-speed fan that stays quiet at low power and ramps up as needed.
• Optional remote control for instant switch-off of the inverter and all connected equipment (not available for the 300W and 500W models).
• Convenient connections with a standard plug; 2500W/3500W models can be hard-wired for permanent installations.
• Reliable grid-quality output at 115/120 V — 50/60 Hz (selectable) to match regional standards.
• MasterBus compatible for seamless integration with Mastervolt ecosystems via the MasterBus AC Master Interface.
