Victron MultiPlus-II 12/3000/120-50 120V Inverter Charger

Key Features

120V Single-Phase Output with Versatile Input Options
The MultiPlus-II supports 120V single-phase input and output, ensuring seamless power supply. When an AC source is available, it mirrors the input voltage to its output. During inverter mode, it maintains a stable 120V output, ensuring reliability for sensitive electronics.

PowerControl & PowerAssist – Smart Load Management
A configurable maximum current limit prevents overloading of the grid or generator (PowerControl). The PowerAssist function supplements grid/generator input with battery power when peak demand exceeds supply. When the load decreases, the excess power recharges the battery.

Uninterrupted Power with Dual AC Outputs
The main AC output (L1) provides an uninterrupted power supply (UPS), automatically switching to inverter mode in under 20 milliseconds during a power outage. The second output is only active when AC input is available, making it ideal for non-essential loads that shouldn't drain the battery.

Solar Energy Integration – AC Power During Grid Failures
Compatible with off-grid and grid-tied solar systems, the MultiPlus-II works seamlessly with solar charge controllers and grid-tie inverters, ensuring continuous AC power even during a grid outage.

Scalable for Higher Power Needs
The MultiPlus-II supports parallel operation (up to 6 units for increased capacity) and three-phase operation when three identical models are used. Additionally, it can integrate with an external current sensor (sold separately) to optimize energy consumption and prevent grid feed-in.

Advanced System Monitoring & Control
Configure settings quickly using VEConfigure software (MK3-USB adapter required). Remote and on-site monitoring options include Cerbo GX, Color Control GX, Venus GX, Bluetooth (with VE.Bus Smart dongle), and the VictronConnect app.

Remote Management & Internet Connectivity
When connected to the Victron Remote Management (VRM) portal via a GX device (e.g., Cerbo GX), users can monitor and configure settings remotely. The system provides real-time energy tracking, battery status, and customizable alerts.

Enhanced Protection & Efficiency
- UL458 certified for safety compliance
- High efficiency of up to 93%
- Multiple protection layers: short circuit, overload, battery voltage monitoring, and temperature regulation
- Supports programmable relay for alarms, DC under-voltage alerts, or generator start/stop automation
