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\n- 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.\n- 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.\n- 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.\n- 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.\n- 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.\n- 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.\n- Two-unit scalability: parallel configurations support up to two Mass Combi units, enabling higher total output for larger systems without sacrificing reliability.\n- 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.\n- 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\n- Ideal for marine vessels, motorhomes, caravans, and off-grid cabins where space is limited, noise matters, and dependable power is non-negotiable.\n- Perfect for users who need to prioritize critical loads during outages or when shore power is unstable, while still keeping comfort and devices online.\n- 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\n- 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.\n- 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.\n- 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.\n- 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)\n- Nominal DC voltage: 12 V (range 10–15 V)\n- AC output: 230 V (±5%), 50\/60 Hz selectable\n- Output waveform: true sine wave, THD \u0026lt; 2.5% under standard conditions\n- Continuous power: up to 12,150 W (cos φ ~ 1)\n- Max peak load: up to 4,000 W\n- Efficiency: ≥ 90%\n- Battery charging: 3-step+ charger, accepts 180–265 V input, up to 100 A charging current at 14.25 V\n- Secondary charger output: 12 V, up to 5 A\n- Transfer system: fast, seamless switching (typical 10 ms, up to 25 ms)\n- Parallel\/2-unit capability: up to 2 Mass Combi units in parallel\n- Battery types supported: AGM, gel, MLI, flooded, spiral, traction\n- Temperature range: -25 °C to 60 °C (with safe derating beyond 25 °C)\n- Standby and efficiency features: low no-load draw on AC and intelligent energy management when idle\n- Physical footprint: 496 x 318 x 156 mm; weight 11 kg\n- Accessories: battery temperature sensors included; automatic voltage sense ensures accurate charging What you’ll experience in daily use\n- Seamless power transitions keep your devices and appliances online even when shore power fluctuates or generator output dips.\n- Cleaner, safer charging means longer battery life and better performance from AGM, gel, or flooded batteries, with less wear and tear from ripple.\n- 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.\n- Quiet operation makes a real difference in living and working spaces where noise and vibrations matter. Tips to maximize performance\n- Pair with appropriately sized two-bank battery configurations to fully leverage simultaneous charging and Power Assist during low-grid availability.\n- Use the automatic voltage sense and battery temperature compensation to optimize charging profiles for varying climates and battery chemistries.\n- 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.\u003c\/div\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":48371209568541,"sku":"MV-36012200-asm","price":3500.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0864\/1072\/3613\/files\/mastervolt-battery-chargers-mass-combi-12v-2200-watts-230volts-mv-36012200-asm-battery-combi-inverter-charger-12v-2200w-output-1191970869.jpg?v=1772754980","url":"https:\/\/actionoutdoors.kiwi\/products\/mastervolt-mass-combi-12-2200-100-inverter-charger-true-sine-wave-for-boats-and-rvs","provider":"Action Outdoors Limited","version":"1.0","type":"link"}
