xVictron MultiPlus 12/1200/50-16 230V VE.Bus Inverter Charger — PMP122120000
The Victron MultiPlus 12/1200/50-16 is a combined inverter and battery charger in a single unit, designed for 12V battery systems with a 230V AC output. It is suited to off-grid installations, marine and vehicle applications, and backup power systems where a compact, reliable inverter charger is required. The 50A charger and 16A transfer switch make it a practical choice for installations with a shore power or generator input.
Key Features
- 1200VA continuous inverter output at 230V AC from a 12V DC battery bank.
- 50A battery charger with adaptive charge algorithm to suit a range of battery chemistries.
- 16A AC transfer switch for automatic changeover between shore/generator power and inverter output.
- VE.Bus communication interface for system integration, remote monitoring and parallel or three-phase configuration with compatible Victron units.
- PowerAssist function supplements shore or generator power to prevent overload on limited AC supplies.
- UPS functionality with near-instant transfer time, suitable for sensitive loads.
- Compatible with Victron GX devices and the VictronConnect app for configuration and monitoring.
Product Overview
The MultiPlus combines a sine wave inverter with a multi-stage battery charger. When AC input is available from shore power or a generator, the unit charges the battery bank and passes power through to connected loads. When AC input is lost or disconnected, it switches to inverter mode automatically. The transfer time is fast enough for most computers and other sensitive equipment to remain operational without interruption.
The 50A charger is a meaningful specification for a 12V system. It allows reasonably fast recharge from a generator without requiring extended run times. The adaptive charge algorithm adjusts to the battery's condition over time, which is particularly useful in installations where the battery bank is not always fully discharged before recharging. The unit supports lead-acid (AGM, gel, flooded) and lithium battery banks when configured appropriately.
VE.Bus connectivity allows the MultiPlus to be integrated into larger Victron systems. Multiple units can be configured in parallel to increase output capacity, or in split-phase and three-phase arrangements. This makes the MultiPlus 12/1200/50-16 a starting point for scalable off-grid and backup systems rather than a fixed-capacity standalone unit.

Installation Notes
The MultiPlus 12/1200/50-16 must be installed by a qualified electrician. Connections to battery banks, AC distribution boards and any grid or generator supply must comply with current UK wiring regulations (BS 7671). For installations forming part of a grid-connected system, G98 or G99 compliance requirements apply and the relevant DNO notification process must be followed. Lithium battery compatibility requires correct configuration via VE.Bus or VictronConnect before commissioning. Ensure DC cabling is rated for the high currents involved at 12V and that appropriate fusing is fitted at the battery.
