The Victron MultiPlus 24/3000/70-50 combines a true sine wave inverter and a battery charger in one enclosure, built for 24V battery systems. It delivers 3000VA of continuous inverter output alongside a 70A charger, with a 50A AC transfer switch for shore power or generator input.

Key features

• Inverter output, 3000VA / 2400W continuous, 230V AC at 50Hz
• Battery charger, 70A multi-stage adaptive charge algorithm, compatible with flooded lead-acid, AGM, gel and lithium batteries
• AC transfer switch, 50A, switches to inverter mode in under 20 milliseconds on loss of AC input
• PowerControl and PowerAssist, limits draw from shore or generator supply and supplements it with battery power when demand exceeds the input current limit
• VE.Bus interface, supports parallel and three-phase configuration with multiple units, plus integration with Victron system monitoring products
• Programmable relay, configurable via VEConfigure software

Product overview

The 70A charger runs a four-stage process: bulk, absorption, float and storage. The 50A transfer switch passes a single AC input, typically generator or shore supply, through to connected loads while charging the batteries at the same time. VE.Bus, Victron's own communication bus, links multiple MultiPlus units for split-phase, parallel or three-phase operation, and connects to the Victron Color Control GX, Cerbo GX and other monitors for remote visibility.

PowerAssist draws the balance of power required from the battery bank when a generator or limited shore supply cannot meet demand alone, effectively extending the AC capacity available beyond what the input alone could supply.

At 18.85kg this is a fixed-installation unit, not a portable one. It runs from a 24V DC battery bank and outputs 230V AC at 50Hz, matching standard UK and European loads.

Applications

• Off-grid cabins, lodges and rural properties needing 230V AC from a 24V battery bank
• Marine vessels requiring shore power passthrough with automatic switchover to inverter
• Vehicle conversions such as HGVs, coaches and expedition vehicles needing charger and inverter combined
• Backup power for communications, medical or security equipment
• Generator-assisted off-grid systems where PowerAssist reduces generator runtime

What's included

• 1 x Victron MultiPlus 24/3000/70-50 230V VE.Bus inverter charger unit

Installation notes

This unit must be installed by a qualified electrician or accredited installer, involving connections to battery, AC input and AC output circuits.
