Victron Energy MultiPlus-II 12/3000/120-50 VE.Bus Pure Sine Wave Inverter/Charger (UL-458)

The Victron Energy MultiPlus-II 12/3000/120-50 combines a true sine wave inverter, an adaptive battery charger, and a high-speed 50A AC transfer switch in a single compact enclosure. The inverter provides 120V single-phase output and, in inverter mode, connects both output lines (L1 and L2) to supply 120VAC loads on either line.

Advanced features include dual AC outputs, parallel operation for increased power, split-phase and three-phase capability, and PowerAssist technology to supplement shore or generator power when needed.

When paired with a compatible GX device, such as the Cerbo GX, the MultiPlus-II can be monitored and controlled locally or remotely through Victron Energy’s VRM platform. Users can access system information and controls from a phone, tablet, laptop, or desktop computer. Remote functions can include system monitoring, inverter settings, and automatic backup generator control.

Victron Energy is one of the leading manufacturers of renewable energy systems and has earned an outstanding reputation for technical innovation, reliability, and quality. The company has served the off-grid, industrial, vehicle, commercial marine, and recreational marine markets for more than 45 years.

The MultiPlus-II Series is certified to the UL 458 standard.
