Victron Energy MultiPlus-II 48/8000/110-100/100 230V Inverter Charger – PMP482805000

Product Overview

The Victron Energy MultiPlus-II 48/8000/110-100/100 230V is a powerful inverter charger designed for 48V battery systems. Combining a pure sine wave inverter, 110A battery charger and 100A AC transfer switch, it provides reliable power conversion and management for off-grid solar, home energy storage, commercial and backup power systems.

With an inverter capacity of 8000VA and continuous output of 6400W at 25°C, it converts 48V DC battery power into 230V AC electricity. PowerControl and PowerAssist help manage limited AC supplies, while UPS functionality provides automatic changeover to inverter power if the incoming supply fails.

Key Features and Benefits

The MultiPlus-II offers high-capacity inverter performance, adaptive battery charging and intelligent AC power management in one unit. Its two AC outputs allow essential and non-essential loads to be managed separately in suitable installations.

VE.Bus communication supports integration with compatible Victron Energy monitoring and control equipment. Compatible parallel and three-phase configurations allow the system to be expanded for larger power requirements.

Applications

Suitable for off-grid solar installations, residential battery storage, generator-backed systems, emergency backup power, commercial applications and appropriately designed marine or mobile installations.

When combined with compatible batteries, solar charge controllers and other equipment, the MultiPlus-II can form part of a complete energy storage system.

PowerControl, PowerAssist and UPS

PowerControl limits current drawn from an external AC supply, helping prevent overloads when using a generator or restricted mains connection. PowerAssist supplements available AC power with battery energy when demand increases.

The integrated transfer switch automatically changes suitable loads to inverter power when the incoming AC supply fails. Actual backup performance depends on battery capacity, connected equipment and system configuration.

Battery Compatibility and Installation

The 110A charger supports compatible 48V battery systems. Charging voltages and current limits must be configured according to the battery manufacturer's requirements, particularly when using lithium batteries with a battery management system.

Professional installation is recommended. Correctly rated cabling, fuses, circuit protection, earthing and ventilation are essential for safe operation.
