Description
xVictron MultiPlus 12/3000/120-16 230V VE.Bus Inverter Charger — PMP122300001
The Victron MultiPlus 12/3000/120-16 is a combined inverter and battery charger in a single unit, designed for 12V battery systems requiring 3000VA of AC output at 230V. It is suited to off-grid installations, marine and vehicle applications, and backup power systems where a reliable, high-capacity inverter charger is needed in a compact form.
Key Features
- 3000VA continuous inverter output at 230V AC from a 12V DC battery bank.
- 120A battery charger built in, with a 16A AC passthrough current for shore or generator power.
- PowerAssist function supplements shore or generator power with battery power when AC demand exceeds the available input current.
- VE.Bus communication interface for system integration, remote monitoring and parallel or three-phase configuration with additional units.
- Virtually no-break transfer switching: the MultiPlus switches from inverter to charger mode in under 20 milliseconds, maintaining continuity for sensitive loads.
- Programmable relay and configurable charge algorithm to suit a range of battery chemistries including lead-acid and lithium.
- Ignition-proof design suitable for use in enclosed spaces such as engine rooms and vehicle installations.
Product Overview
The MultiPlus 12/3000/120-16 combines a pure sine wave inverter with a high-current multi-stage battery charger. When AC input is available (shore power or a generator), the unit charges the battery bank and passes power through to connected loads. When AC input is lost or disconnected, it switches to inverter mode automatically. The 120A charge current is substantial for a 12V system and allows a large battery bank to be charged efficiently without a separate charger.
The 16A AC input current limit reflects the unit's intended use in contexts where the available AC supply is limited, such as a 16A shore power connection on a boat or a small generator. The PowerAssist feature is particularly useful in these situations: if connected loads draw more than the incoming AC can supply, the MultiPlus draws the shortfall from the battery rather than tripping the supply breaker. This allows a modest AC input to support peak loads that would otherwise exceed its rating.
VE.Bus connectivity means the unit can be monitored and configured via Victron's GX devices, Color Control GX, or Cerbo GX. Multiple units can be connected in parallel for increased capacity, or configured for split-phase or three-phase output. Configuration is carried out using VEConfigure software via a VE.Bus to USB interface (sold separately).

Installation Notes
Installation should be carried out by a qualified electrician or accredited installer with experience in DC and AC electrical systems. The MultiPlus must be connected to an appropriately rated 12V battery bank with correctly sized DC cabling and fusing. For any grid-connected or shore-power application in the UK, ensure the installation complies with current wiring regulations (BS 7671) and any applicable network operator requirements. Configuration of charge parameters and system settings requires VEConfigure software and a VE.Bus to USB interface, which are not included. For lithium battery installations, verify compatibility and configure the appropriate battery protection settings before commissioning.
