Mass Combi PRO 12/3000-150 Inverter- Charger

Meet the Mass Combi PRO 12/3000-150 Inverter-Charger—a professional-grade power solution designed for demanding applications where reliability, efficiency, and seamless energy management matter most. Delivering 3000 W of continuous inverter power from a 12 V DC input and a robust 150 A charging capability, this unit keeps critical loads humming even when mains quality is unpredictable.

Why choose the Mass Combi PRO 12/3000-150

• Pro-grade performance with focused features. This model carries all Ultra functions in a streamlined package, specifically configured without solar input and a secondary battery charger, delivering a compact, mission-critical solution for professional sites.
• Power Assist for rock-solid reliability. Automatically compensates for weak mains or small generators, preventing voltage dips and outages when you need power most.
• Digital precision and fast source switching. A high-speed Digital Signal Processor ensures instant, seamless switching between grid, generator, and battery power, so loads never stumble.
• Quiet, efficient operation. Up to 50% of charging or inverter capacity runs without a fan at light loads, and Active Optima Cooling linearly modulates fan speed to minimize noise and wear during heavy demand.
• Pure sine wave with impressive headroom. True sine wave output supports sensitive gear, with a 200% peak capacity to handle heavy start-up loads without faltering.
• Smart charging protects battery life. The built-in charger delivers a full charge current up to 150 A at 40 °C, with low ripple and smart IUoUo charging tailored for Gel, AGM, flooded, and other lead-acid chemistries.
• Versatile system integration. Paralleling up to 10 units and three-phase configurations up to 3x3 enable scalable power for larger installations, while seamless synchronization with mains or a generator keeps your system stable.

What it does well in real-world scenarios

Designed for professionals who require dependable power in challenging environments—marinees, work sites, telecommunications, broadcast, and backup power for critical equipment. When mains quality is inconsistent or a generator is the only reliable source, the Mass Combi PRO maintains voltage, avoids dips, and starts heavy loads smoothly. In night-time operation, the unit can run with no audible fan noise, preserving a quiet environment while essential systems stay online.
