Deliver Reliable 120V Power with a High-Capacity 12V Inverter and Battery Charger

The Victron MultiPlus-II 12/4k/160-50 is a multifunction inverter/charger that combines a pure sine wave inverter, high-current battery charger and high-speed AC transfer switch in a single unit. Suitable for marine, vehicle, off-grid and energy storage applications, it supports PowerAssist and PowerControl technologies to maximise available shore, generator or grid power while protecting the input supply from overload. It also supports parallel, split-phase and three-phase operation, providing a flexible platform for larger power systems with advanced monitoring and remote management capabilities.

Key Features

• 3400W Continuous AC Output: Delivers 3000VA (3400W) continuous output at 25°C with up to 6kW peak power for demanding electrical loads.
• 160A High-Capacity Battery Charger: Integrated charger provides up to 160A charging current for rapid battery replenishment from shore power or a generator.
• PowerAssist & PowerControl: Automatically supplements limited AC input with battery power during peak demand while preventing overload of shore or generator supplies.
• Fast 50A Transfer Switch: Transfers connected loads to inverter power in less than 20 milliseconds during an AC power interruption, helping sensitive equipment continue operating.
• Dual AC Outputs: Includes a primary uninterrupted output and a secondary output that is active only when external AC power is available, making it suitable for non-critical loads.
• Scalable System Architecture: Supports parallel operation, split-phase and three-phase configurations for increased output capacity and flexible system expansion.
• ESS Ready: Compatible with Victron Energy Storage System (ESS) installations and renewable energy applications including solar charge controllers and grid-tie inverters.
• Remote Monitoring and Configuration: Compatible with Cerbo GX, Ekrano GX and the Victron VRM Portal for remote monitoring, system management and configuration.
• VE.Bus Communication: Supports system integration, remote monitoring and advanced configuration through the VE.Bus communication interface.
• Battery Temperature Sensor Included: Automatically adjusts charging based on battery temperature for improved charging performance.

The MultiPlus-II 12/4k/160-50 combines inverter, charger and intelligent power management into a single platform for demanding mobile, marine and off-grid power systems. Its scalable design and advanced monitoring capabilities make it suitable for both standalone and integrated energy installations.
