MultiPlus – Victron’s Versatile Inverter-Charger System

The Victron MultiPlus combines inverter, battery charger, and automatic transfer switch functionality in a single integrated unit. This versatile system delivers pure sine wave AC power from battery sources while simultaneously charging batteries when AC input is available. The MultiPlus automatically switches between grid, generator, and battery power, maintaining continuous operation for connected loads during transitions.

The MultiPlus product line includes models ranging from 500VA to 5kVA across various voltage configurations including 12V, 24V, and 48V DC input options. Split-phase 120V/240V models serve North American residential applications with proper configuration. The PowerAssist feature supplements weak AC sources with battery power, preventing generator or grid overload while maintaining full load support.

MultiPlus systems support parallel and three-phase configurations through VE.Bus communication, enabling capacity expansion and redundancy. Integration with GX monitoring devices provides comprehensive system visualization through VictronConnect app and VRM portal access. Advanced features include programmable relay outputs, adjustable charging algorithms for LiFePO4 and lead-acid batteries, and remote configuration capabilities.

The adaptive charging technology optimizes battery health while the built-in transfer switch provides seamless power transitions. MultiPlus units meet international safety standards and support ESS (Energy Storage System) applications with grid-support capabilities.
