Mastervolt CombiMaster 24/2000-40 230V Inverter For Boats And RVs

The CombiMaster 24/2000-40 is designed to keep life on board or on the road uninterrupted by delivering reliable 230V AC from a 24V battery bank. This compact, lightweight inverter acts as the core of a smart power system, handling even heavy and sensitive loads with ease while staying remarkably user‑friendly.

Why it stands out

This inverter goes beyond simple conversion. Its automatic AC transfer system seamlessly switches between mains or generator input and inverter output, guaranteeing a steady power supply to essential appliances no matter the scene. When you’re connected to a weak shore line or a small generator, Power Assist steps in to prevent nuisance tripping of the mains fuse, keeping your comfort devices running without interruption.

Smart charging and reliability

The intelligent 3‑step+ battery charger optimizes charging for faster, safer replenishment of your batteries, helping extend their life and reliability. The CombiMaster is built to start and sustain demanding loads while delivering hum‑free operation that protects sensitive electronics and equipment.

Integrated, future‑proof connectivity

Mastervolt’s reputation for thoughtful integration shines here. The CombiMaster ships with built‑in MasterBus, CZone, and NMEA 2000 compatibility, opening a broad spectrum of monitoring and system‑integration possibilities. This means you can monitor and control charging, load, and power flow from familiar interfaces across a range of displays and third‑party systems.

• Remote control and monitoring: MasterBus via SmartRemote or EasyView 5
• CZone / NMEA 2000 compatibility: Touch 5 or Touch 10 displays, or third‑party multifunction displays
• Generator compatible and quick to install with heavy‑duty connections
• E‑mark certified for 230V models

Compact performance, ample capability

In a single, streamlined enclosure, the CombiMaster combines power, efficiency, and reliability. Its design prioritizes ease of installation and operation, so you can position it in a convenient location without sacrificing performance. The unit is purpose‑built to drive even the heaviest and most sensitive loads, ensuring you have dependable power for navigation gear, climate control, refrigerators, and daily comforts on both boats and RVs.

Real‑world use cases

On a boat, run critical systems like radar, chartplotters, fridges, and lighting without worrying about fluctuating shore power. When anchored or camping off the grid, rely on the inverter to maintain comfortable living conditions while your battery bank charges efficiently. The combination of automatic transfer, Power Assist, and a robust charging profile means fewer outages and more time enjoying your surroundings.

Practical tips for getting the most out of your CombiMaster

• Pair with compatible MasterBus or NMEA 2000 displays to centralize monitoring and control.
• Ensure your battery bank size matches peak loads to maximize inverter efficiency and battery life.
• Regularly test the automatic transfer and Power Assist functions to confirm seamless switching during trips.
