Description
xVictron MultiPlus 12/800/35-16 230V VE.Bus Inverter Charger — PMP121800000
The Victron MultiPlus 12/800/35-16 is a combined inverter and battery charger in a single unit, designed for 12V DC systems with 230V AC output. It is suited to off-grid installations, marine and vehicle applications, and backup power systems where a compact, reliable inverter charger is required.
Key Features
- Combined inverter and charger in one unit, eliminating the need for separate devices and reducing installation complexity.
- 800VA continuous inverter output at 230V AC, suitable for powering household and light commercial loads from a 12V battery bank.
- 35A battery charger with adaptive charge algorithm, adjusting charge current and voltage to suit the connected battery type.
- 16A AC passthrough, allowing shore or generator power to supply connected loads directly while simultaneously charging the battery.
- VE.Bus communication interface, enabling system integration with other Victron devices, remote monitoring, and configuration via VEConfigure software.
- PowerAssist function, which supplements shore or generator power with battery power when load demand exceeds the AC input limit.
- Transfer switch with fast switchover time, maintaining power to connected loads when transitioning between inverter and AC input.
- Configurable for various battery chemistries including flooded, AGM, and gel lead-acid batteries.
Product Overview
The MultiPlus 12/800/35-16 integrates an 800VA inverter with a 35A multi-stage battery charger. The 16A AC input rating means it can accept power from a standard shore connection or a small generator, passing that power through to loads while charging the battery bank. When AC input is unavailable or overloaded, the unit switches to inverter mode automatically. The PowerAssist feature is particularly useful in situations where the available AC supply is limited: the unit draws additional power from the battery to cover peak loads, preventing nuisance tripping of shore power breakers.
VE.Bus connectivity allows the MultiPlus to be configured and monitored remotely using Victron's GX devices and the VRM portal. Multiple units can be configured in parallel or three-phase arrangements using the broader Victron ecosystem, though at this power level the unit is most commonly deployed as a standalone inverter charger. The adaptive charger algorithm monitors battery condition over time and adjusts the charge profile accordingly, which is relevant for installations where the battery bank may sit at partial state of charge for extended periods.
At 6.5kg, the unit is compact enough for installation in confined spaces such as boat engine rooms, vehicle bays, or small off-grid enclosures. The 230V AC output conforms to standard European and UK voltage requirements.

Installation Notes
Installation should be carried out by a qualified electrician or accredited installer familiar with DC battery systems and 230V AC wiring. The unit must be connected to an appropriately rated 12V battery bank with correctly sized DC cabling and fusing. For any grid-connected or shore-power applications in the UK, ensure compliance with relevant wiring regulations. VE.Bus configuration requires Victron's VEConfigure software and a suitable interface cable or MK3-USB adapter. Do not install in locations subject to direct water ingress or excessive heat without appropriate enclosure protection.
