Victron MultiPlus 12/1200 - 50-16 - 120V - VE. Bus

The MultiPlus 12/1200 - 50-16 - 120V - VE.Bus is an advanced power solution tailored for marine and boating applications. Combining a true sine wave inverter, a state-of-the-art battery charger with adaptive technology, and a high-speed AC transfer switch, it ensures reliable and efficient power management on the water. This compact yet powerful device is equipped with multiple features designed to enhance your maritime experience.

Key Features

Parallel Operation and Three-Phase Capability

Expand your power system effortlessly by connecting up to six MultiPlus units in parallel for increased power output. Additionally, configure three units to achieve a three-phase power setup, providing flexibility and scalability to meet your vessel's energy demands.

PowerControl: Optimize Limited Power Sources

Set a maximum generator or shore power current using the Multi Control Panel. The MultiPlus intelligently manages additional AC loads, utilizing excess power for battery charging while preventing overloads from generators or shore supplies.

PowerAssist: Enhance Shore or Generator Capacity

PowerAssist takes PowerControl a step further by supplementing limited shore or generator power with battery energy. It seamlessly compensates for power deficits during peak demands and recharges the battery when the load decreases, ensuring consistent power availability.

Advanced Four-Stage Adaptive Charger

The MultiPlus features a four-stage adaptive charger that dynamically adjusts the charging process based on battery condition. This ensures optimal battery health and longevity, with an additional trickle charge output for a secondary battery, perfect for starter or generator batteries.

High Start-Up Power

Designed to handle high-inrush loads, the MultiPlus reliably starts power converters for LED lamps, halogen lighting, and electric tools, ensuring your essential equipment operates smoothly.

Energy-Efficient Search Mode

When activated, Search Mode reduces the inverter's no-load power consumption by approximately 70%. The system periodically checks for load presence, activating the inverter only when necessary to conserve energy.

Programmable Relay

The built-in programmable relay acts as an alarm system, de-energizing during alerts such as overheating, high input ripple, or low battery voltage. Customize relay functions for additional control and integration with your vessel's systems.

Remote Control and Monitoring

With options for remote on/off control and charger activation, manage your power system conveniently. Utilize VE-Config or the VE.Bus Smart dongle for advanced settings adjustments and system integration.
