The Victron MultiPlus 12/1200/50-16 is a compact, reliable 12 V to 230 V pure sine wave inverter/charger with UPS capability: 1200 VA continuous inverter power, 2400 W peak, and a 50 A adaptive 4-stage battery charger for fast, safe charging.

• Combines inverter, battery charger and AC transfer switch: converts DC current into 230 VAC for household and sensitive loads.
• Inverter: 12 V pure sine wave inverter; input voltage range 9.5–17 V; output 230 VAC ±2% @ 50 Hz; continuous power 1200 VA; peak (surge) power 2400 W; maximum efficiency 93%; zero-load power 10 W.
• Charger: adaptive 50 A 4-stage smart battery charger (bulk – absorption – float – storage) with temperature compensation (sensor supplied); AC input range 187–265 VAC; charge voltages absorption 14.4 V, float 13.8 V, storage 13.2 V; starter battery charge 1 A. Bulk protection: when enabled, bulk charging time is limited to 10 hours.
• Uninterruptible power supply (UPS): high-speed 16 A AC transfer switch maintains power to sensitive loads during source changes.
• Additional intelligent features: PowerControl (set the maximum AC input current), PowerAssist (supplement the capacity of the AC supply to prevent overload) and a programmable relay for custom alarms and controls; dip switches for remote, battery charge voltage and inverter settings.
• Parallel and 3-phase operation capability: connect multiple identical units in parallel or in three-phase systems to increase capacity.
• Inbuilt protection and operating modes: protection against output faults, WeakAC behaviour (strong distortion of the input voltage can cause the charger to reduce or stop charging), BatterySafe mode to protect the battery when high charge currents are used, and Storage mode which activates when the battery has not been discharged for a period to reduce long-term battery wear.
• Remote monitoring and control: compatible with GX devices (e.g., Cerbo GX) for real-time monitoring and configuration across systems.

Suitable for marine, RV and off-grid applications. Follow battery maker guidelines for charging profiles and have installation performed by a qualified technician.
