The Victron MultiPlus 24/3000/70-16 combines an inverter and a battery charger in one unit for 24V battery bank systems. It puts out 3000VA of continuous AC power at 230V and includes a 70A charger, so a single enclosure covers both inversion and charging for off-grid, marine or vehicle installations.

Key features

• Inverter output, 3000VA continuous at 230V AC, 6000VA peak surge, 50Hz
• Battery charger, 70A multi-stage output for 24V AGM, gel, lithium and flooded lead-acid batteries
• Transfer switch, 16A AC transfer with PowerControl and PowerAssist
• Communication, VE.Bus interface for Victron GX devices and VEConfigure software
• Transfer time, under 20ms in UPS mode
• Expandable, units can be paralleled or wired for three-phase output

How PowerAssist works

On a limited AC supply, such as shore power or a small generator, the MultiPlus draws any shortfall from the battery bank instead of overloading the source. A 16A supply can then run loads that would otherwise trip a breaker. PowerControl applies the same current-limiting logic when PowerAssist is switched off.

System integration

VE.Bus lets the MultiPlus connect into a wider Victron setup. It can be monitored and configured remotely through a Cerbo GX or other GX device. Multiple units can be paralleled for extra capacity or arranged for three-phase output, so the 24/3000/70-16 works as a building block rather than a fixed-capacity unit.

Applications

• Off-grid cabins and homes with a 24V battery bank needing both inversion and charging
• Marine systems combining shore power in port with battery-backed AC at sea
• Motorhome and vehicle conversions needing 230V AC from a 24V house battery
• Backup power for IT, communications or medical equipment where sub-20ms transfer matters
• Multi-unit systems scaled through parallel stacking or three-phase wiring
