Mastervolt 35511500 CombiMaster 12/1500-60 (120V): Compact, Reliable Inverter/Charger Power for Mobile & Marine Systems

When dependable AC power is essential—whether onboard a vessel, inside an RV, or within a mobile service vehicle—the Mastervolt CombiMaster 12/1500-60 delivers a refined balance of performance, efficiency, and intelligent system control. Designed for real-world power demands, this compact inverter/charger drives sensitive electronics and heavy loads alike while maintaining seamless power continuity.

Built around reliability and ease of use, the CombiMaster range ensures that power dips, interruptions, and generator limitations are handled automatically—so your system keeps running without manual intervention.

Multifunctional Power in One Compact Unit

The Mastervolt 35511500 CombiMaster 12/1500-60 (120V) combines three critical power functions into a single, space-efficient enclosure:

• Pure sine wave inverter for clean, stable AC power
• Intelligent 3-step+ battery charger for fast, safe battery replenishment
• Automatic AC transfer switch for seamless switching between inverter, shore power, or generator input

This integration reduces wiring complexity, saves installation space, and improves overall system reliability.

Automatic AC Transfer & Power Assist Technology

Power interruptions are virtually eliminated thanks to the CombiMaster’s high-speed AC transfer system. When shore or generator power is available, it is passed directly to connected loads. If that source is lost, the inverter instantly takes over—keeping electronics and appliances running smoothly.

The built-in Power Assist feature goes a step further. When connected to a weak shore connection or undersized generator, the system supplements incoming AC power with battery energy. This prevents nuisance breaker trips and blown fuses while allowing higher peak loads when needed.

Drives Heavy & Sensitive Loads with Ease

Despite its compact size, the CombiMaster 12/1500-60 is engineered to start and run demanding equipment without voltage drop or electrical noise. This makes it suitable for:

• Navigation and communication electronics
• Refrigeration and galley appliances
• Power tools and service equipment
• Audio-visual systems and sensitive electronics

Reliable, hum-free operation ensures longer runtime from your batteries and consistent AC output under load.

Intelligent Charging for Long Battery Life

The integrated charger uses an advanced 3-step+ charging algorithm, optimizing charge speed while protecting battery health. This approach improves efficiency, reduces heat generation, and extends battery lifespan across a wide range of battery types.

For users building complete systems, this charger pairs naturally with modern lithium and AGM battery banks, forming the backbone of a stable AC/DC power architecture.

Advanced System Integration & Monitoring

As expected from Mastervolt inverter-charger systems, the CombiMaster is designed for seamless integration into larger power networks. It supports:

• MasterBus communication for centralized system control
• CZone compatibility for digital switching and automation
• NMEA 2000 connectivity for marine multifunction displays

Monitoring and control options include SmartRemote, EasyView 5, Touch 5, Touch 10, and compatible third-party displays—allowing full system visibility from a single interface.
