Victron Energy MultiPlus-II 48V 3000VA 2400W 120V Pure Sine Wave Inverter Charger, 35A Battery Charger, 50A Transfer Switch, ESS Compatible

The Victron Energy MultiPlus-II 48V 3000VA 2400W 120V Inverter Charger (Model 48/3000 35-50 120V, MPN PMP482305100) combines a high-efficiency pure sine wave inverter, a 35A adaptive battery charger, and a 50A transfer switch in one compact unit. Built for off-grid solar, marine, RV, backup power, and energy storage systems, this 48 volt inverter charger delivers reliable 120VAC power with intelligent energy management through Victron PowerControl and PowerAssist technology.

48V 3000VA / 2400W Pure Sine Wave Inverter Charger

The MultiPlus-II provides 3000VA of inverter capacity with 2400W continuous output at 25°C, 5500W peak power, and up to 95% efficiency. It supports solar, battery storage, generator, and grid-connected installations, with a built-in battery temperature sensor for optimized charging.

PowerControl and PowerAssist for Generators, Shore, and Grid Power

PowerControl helps prevent generator, shore power, or grid overloads by intelligently managing available AC power. When extra power is needed, PowerAssist supplements the AC source with battery energy, then uses available power to recharge the battery once loads decrease.

Built-In UPS Backup Power

If grid, generator, or shore power is interrupted, the MultiPlus-II takes over in less than 20 milliseconds, providing seamless backup power for computers, electronics, appliances, and critical equipment.

Designed for Solar and Energy Storage Systems

The MultiPlus-II is a key component in Victron ESS (Energy Storage System) installations, working with solar charge controllers and grid-tied solar systems to improve self-consumption and energy independence.

Parallel, Split-Phase 240V, and Three-Phase Capability

Up to six MultiPlus-II units can operate in parallel for increased power output, and multiple units can be configured for split-phase 240V or three-phase power systems.

Remote Monitoring and System Control

Paired with a Victron GX device, the MultiPlus-II supports remote monitoring and control through the Victron Remote Management (VRM) platform. Adjust settings, view performance data, monitor battery status, and manage connected equipment from anywhere.
