Mastervolt AC Master 12/700 (120V) Inverter

The AC Master 12/700 (120V) Inverter is the perfect solution for providing reliable and stable AC power on your boat or marine vessel. Designed specifically for the demanding marine environment, this inverter ensures your essential equipment runs smoothly, whether you're cruising the open seas or anchored at a marina.

Features

• Pure Sine Wave Technology: Protects sensitive marine electronics such as GPS, radios, and navigation systems.
• High Peak Power Delivery: Maintains full output even under the most demanding conditions, ideal for powering onboard appliances and tools.
• Automatic Power-Saving System: Extends runtime by intelligently managing power consumption, crucial for long voyages.
• Compact and Lightweight Design: Saves valuable space in your boat’s limited installation areas.
• Robust Protection Features: Safeguards against over-temperature, overload, short circuits, and voltage fluctuations, ensuring safe operation in a marine setting.
• Variable-Speed Fan: Operates quietly at low power, minimizing noise on your vessel.
• Optional Remote Control: Allows instant switching off of the inverter and all connected equipment remotely (not available for the 300 and 500 W models).
• Flexible Connection Options: Features a convenient plug connection for all models, with 2500/3500 Watt models also offering hard-wired options.

Applications

• Ideal for both recreational and semi-professional marine use, especially in situations where grid power is unavailable or inconsistent.
• Powering essential onboard lighting, kitchen appliances, electric cooking devices, and power tools.
• Supports mobile applications in your yacht, fishing boat, motorhome, or service vehicle during extended trips or holidays.
