Description
xVictron MultiPlus 48/800/9-16 230V VE.Bus Inverter Charger
The Victron MultiPlus 48/800/9-16 is a combined inverter and battery charger in a single compact unit, designed for 48V off-grid and backup power systems operating at 230V AC. It is suited to professional installers working on small off-grid installations, narrowboats, caravans, remote cabins, and UPS applications where a reliable, low-power inverter charger is required.
Key Features
- Combined inverter and charger in one unit, eliminating the need for separate devices in space-constrained installations.
- 800VA continuous inverter output at 230V AC from a 48V DC battery bank.
- 9A battery charging current, with a 16A AC input current rating for shore or generator power.
- VE.Bus communication interface for system integration, parallel operation, and monitoring via Victron GX devices.
- PowerAssist function supplements shore or generator power when demand exceeds the available AC input, preventing overload.
- Transfer switch with a fast changeover time, suitable for use as an uninterruptible power supply (UPS).
- Configurable via VE.Bus and compatible with Victron VE.Configure software for parameter adjustment.
Product Overview
The MultiPlus 48/800/9-16 operates from a 48V battery bank and delivers 800VA of continuous AC output at 230V. The 48V architecture reduces cable current compared to 12V or 24V equivalents, which is a practical advantage in installations where cable runs are longer or where efficiency losses need to be minimised. The 9A charger is sized for smaller battery banks and is appropriate for systems where charging speed is less critical than compact footprint and low cost.
VE.Bus connectivity is a key feature of this unit. It allows the MultiPlus to be monitored and controlled through Victron GX devices such as the Cerbo GX, and it supports configuration via VE.Configure software. Multiple units can be connected in parallel or in split-phase configurations where the system design requires it, though the 800VA model is most commonly deployed as a standalone unit in small systems.
The PowerAssist function is particularly useful in installations with a limited AC input, such as a small generator or a restricted shore power connection. When load demand exceeds the available input current, the unit draws the balance from the battery, allowing the system to handle short-term peaks without tripping the input breaker or overloading the source.

Installation Notes
Installation must be carried out by a qualified electrician or accredited installer. The MultiPlus connects directly to a 48V battery bank and to a 230V AC supply, both of which present serious electrical hazards if wired incorrectly. Ensure battery cabling is correctly rated for the DC current involved and that appropriate fusing is fitted on the battery connection. This unit is not certified for grid-tied export in the UK and must not be connected to the grid without appropriate isolation and compliance with G98 or G99 requirements. For off-grid and UPS applications, follow Victron's published wiring guidelines and use VE.Configure software to set battery parameters appropriate to the chemistry in use.
