The Victron MultiPlus-II 48/15000/200-100 230V is a battery charger with inverter built into a single unit, rated for 15,000VA continuous output from a 48V battery bank. It combines a pure sine wave inverter, a 200A charger and an AC transfer switch, making it suited to demanding off-grid, backup and hybrid solar installations that need high continuous power and fast recharging.

Key features of this battery charger with inverter

• Inverter output, 15,000VA continuous, pure sine wave, 230V AC
• Charger, 200A output with adaptive charge algorithm for 48V battery banks
• AC input limit, 100A, configurable via VE.Bus
• PowerAssist and PowerControl, draws extra power from the battery when demand exceeds the AC input limit, preventing generator or shore power overload
• Transfer switch, integrated, with fast changeover for UPS style backup
• Monitoring, VE.Bus connectivity for configuration and integration with GX devices

Product overview

This is one of the largest single unit inverter chargers in the Victron range. At 15kVA it can supply substantial loads directly from a 48V bank, and the 200A charger recharges a large battery quickly from generator or grid power, cutting generator run time in hybrid systems. PowerAssist lets a smaller generator work alongside the battery without tripping, by supplying any shortfall from storage rather than the generator itself. PowerControl performs the same role on a fixed limit grid or shore connection.

Multiple units can run in parallel, or in split phase and three phase arrangements for commercial sites. Configuration and monitoring go through VE.Bus, with full integration into Victron GX devices such as the Cerbo GX and remote access via the VRM portal.

Technical specifications

Applications

Large off-grid residential or commercial sites needing 15kVA continuous output; critical backup systems requiring fast AC transfer; hybrid solar installations with generator backup using PowerAssist; three phase commercial systems built from multiple units; industrial sites with high peak demand on 48V storage; marine and vehicle systems running large 48V DC banks with 230V AC loads.

What's included

• Victron MultiPlus-II 48/15000/200-100 230V inverter charger unit

Installation notes

At 76.5 kg the unit needs careful handling and secure mounting. Installation should be carried out by a qualified electrician experienced with high-capacity inverter systems, and the 48V battery connections must be correctly fused and cabled to the manufacturer's specification. Grid-connected or export-capable UK installations must meet G98 or G99 requirements.
