Mass Combi 12v/2200 watts-230volts

The MasterVolt Mass Combi 12/2200-100 (230 V) is not just a charger or an inverter—it’s a single compact power center that elevates how you power critical devices and keep life aboard or on the go running smoothly. Built for reliability, efficiency, and quiet operation, this 12 V DC to 230 V AC system delivers clean, true-sine energy with smart battery management you can trust. What makes Mass Combi unique - One integrated solution: a sophisticated 3-step+ battery charger paired with a silent inverter in a single, space-saving unit. It charges two independent battery banks simultaneously while delivering stable, high-quality AC power. - True sine, low ripple: pure sine wave output with THD under typical conditions of less than 2.5%, safeguarding sensitive electronics, chargers, tablets, and medical devices from digital glitches or motor stumbles. - Smart energy management: a built-in distribution system automatically switches between grid (mains) power and inverter power, so you always have power where you need it without manual reconfiguration. - Dual outputs for critical loads: two separate AC outputs let you reserve one circuit for essential equipment and the other for heavier loads, improving safety and reliability on boats, RVs, or off-grid setups. - Power Assist for jitter-free operation: when the grid or generator can’t meet demand, Mass Combi draws from the battery banks to provide extra surge power, preventing fuse blows and ensuring seamless startup of demanding devices. - Quiet, efficient, and compact: high-frequency technology keeps the unit lightweight and whisper-quiet, so it preserves living space and reduces noise in cabins or control rooms. - Two-unit scalability: parallel configurations support up to two Mass Combi units, enabling higher total output for larger systems without sacrificing reliability. - Robust charging for long life: intelligent 3-step+ charging (IUoUo) with low DC ripple extends battery life, while the charger is capable of handling two separate banks at once—even if you run different chemistries. - Power you can trust in offshore or remote environments: designed for AGM, gel, MLI, flooded, spiral, and traction batteries, with battery temperature sensing and automatic voltage compensation to optimize charging across conditions. Designed for who and where - Ideal for marine vessels, motorhomes, caravans, and off-grid cabins where space is limited, noise matters, and dependable power is non-negotiable. - Perfect for users who need to prioritize critical loads during outages or when shore power is unstable, while still keeping comfort and devices online. - Great for systems that require two independent battery banks—solar, alternator, or generator inputs can feed separate banks while the Mass Combi manages the rest. Concrete benefits and real-world scenarios - Off-grid living: you can rely on Mass Combi to charge your deep-cycle batteries and provide clean mains-like power for refrigeration, HVAC controls, water pumps, and electronics without a noisy inverter running constantly. - Sea-going comfort: on deck or in the cabin, enjoy quiet operation and dependable power for navigation gear, radios, wine coolers, coffee makers, and charging hubs without hum or flicker. - Emergency backup: during a blackout, Power Assist delivers the extra oomph needed to start compressors or tools, while the integrated distribution and two outputs keep essentials online. - Quick installation, long-term reliability: professional-grade connections and a compact footprint simplify installation and maintenance, reducing downtime and increasing system uptime. Technical snapshot (highlights you’ll feel in daily use) - Nominal DC voltage: 12 V (range 10–15 V) - AC output: 230 V (±5%), 50/60 Hz selectable - Output waveform: true sine wave, THD < 2.5% under standard conditions - Continuous power: up to 12,150 W (cos φ ~ 1) - Max peak load: up to 4,000 W - Efficiency: ≥ 90% - Battery charging: 3-step+ charger, accepts 180–265 V input, up to 100 A charging current at 14.25 V - Secondary charger output: 12 V, up to 5 A - Transfer system: fast, seamless switching (typical 10 ms, up to 25 ms) - Parallel/2-unit capability: up to 2 Mass Combi units in parallel - Battery types supported: AGM, gel, MLI, flooded, spiral, traction - Temperature range: -25 °C to 60 °C (with safe derating beyond 25 °C) - Standby and efficiency features: low no-load draw on AC and intelligent energy management when idle - Physical footprint: 496 x 318 x 156 mm; weight 11 kg - Accessories: battery temperature sensors included; automatic voltage sense ensures accurate charging What you’ll experience in daily use - Seamless power transitions keep your devices and appliances online even when shore power fluctuates or generator output dips. - Cleaner, safer charging means longer battery life and better performance from AGM, gel, or flooded batteries, with less wear and tear from ripple. - The two-output design provides a fail-safe architecture: run critical systems on a dedicated feed while bulk loads stay on the other, reducing risk of brownouts or trips. - Quiet operation makes a real difference in living and working spaces where noise and vibrations matter. Tips to maximize performance - Pair with appropriately sized two-bank battery configurations to fully leverage simultaneous charging and Power Assist during low-grid availability. - Use the automatic voltage sense and battery temperature compensation to optimize charging profiles for varying climates and battery chemistries. - If you anticipate frequent high loads, plan for parallel operation to achieve higher sustainable outputs without compromising efficiency. In short, the Mass Combi 12/2200-100 (230 V) is a purpose-built power partner for anyone who demands reliable, clean energy from a compact, quiet device. It’s not just about having power—it’s about having stable, safe, and scalable power that protects your equipment, extends battery life, and keeps life onboard or off-grid comfortably humming.
