Mastervolt CombiMaster 12/2000-100 (120V): Reliable, Intelligent Power for Mobile & Marine Systems

When consistent AC power is critical—on a vessel, in an RV, or within a mobile work platform—Mastervolt delivers proven inverter-charger systems designed for reliability and long-term performance. Built for demanding environments, the CombiMaster range combines intelligent charging, seamless power switching, and compact engineering into a single, dependable solution.

At the center of this lineup is the Mastervolt CombiMaster 12/2000-100 (120V)—an all-in-one inverter/charger engineered to eliminate power interruptions and simplify energy management.

All-in-One Inverter, Charger & Automatic AC Transfer

The Mastervolt CombiMaster 12/2000-100 integrates three essential power functions into one streamlined unit:

• High-quality inverter delivering stable 120V AC power
• Intelligent battery charging with optimized charge stages
• Automatic AC transfer between shore power, generator, and inverter

When external AC power is available, the system passes it directly through to connected loads. If that source drops or fails, the CombiMaster instantly switches to inverter mode—maintaining uninterrupted power for sensitive electronics and onboard equipment.

Power Assist: More Capability from Limited Shore or Generator Power

A key advantage of the Mastervolt CombiMaster platform is its built-in Power Assist functionality.

This technology:

• Monitors incoming AC supply in real time
• Supplements short-term demand with battery power when needed
• Prevents nuisance breaker trips and blown fuses

For marinas, campgrounds, or remote sites with limited shore power, Power Assist allows users to operate heavier loads without upgrading generators or risking system shutdowns.

Intelligent Battery Charging for Long-Term System Health

As a Mastervolt battery charger, the CombiMaster 12/2000-100 uses an intelligent 3-step+ charging algorithm designed to maximize battery lifespan while reducing charge time.

Charging benefits include:

• Faster, safer charging cycles
• Reduced electrical noise and heat generation
• Optimized performance for AGM, flooded, and modern battery systems

When paired with a compatible Mastervolt battery solution, the CombiMaster becomes the backbone of a highly efficient onboard power system.

Compact Design with Serious Power Capability

Despite its output capacity, the CombiMaster 12/2000-100 remains one of the most compact and lightweight inverter-chargers in its class.

Design highlights:

• Quiet, hum-free operation
• Heavy-duty connections for quick installation
• Efficient thermal management for continuous use

The unit is engineered to start even the most sensitive or high-inrush loads without hesitation.

Advanced Monitoring & System Integration

The CombiMaster is built for modern power architectures and integrates seamlessly with:

• MasterBus monitoring systems
• CZone digital switching networks
• NMEA 2000 marine communication systems

Remote monitoring and control options include SmartRemote, EasyView 5, Touch 5, Touch 10, and compatible third-party NMEA 2000 displays—giving users full visibility and control over their power system.

Ideal Applications

The Mastervolt CombiMaster 12/2000-100 (120V) is well suited for:

• Marine vessels requiring seamless shore-to-ship power switching
• RVs and motorhomes operating on limited external AC sources
• Mobile service vehicles and utility fleets
• Off-grid or hybrid battery-based power systems

Its balance of intelligent control, efficiency, and reliability makes it a versatile solution across multiple environments.
