Product description

The Victron MultiPlus 12/800/35-16 is a compact and powerful inverter/charger combination designed for campervans, motorhomes, boats, and off-grid energy systems. It combines a pure sine wave inverter, an advanced 35A battery charger, and a high-speed AC transfer switch in one integrated unit.

This model is ideal for small to medium 12V systems where reliability, efficiency, and space-saving installation are essential.

ALL-IN-ONE POWER SOLUTION

The MultiPlus combines three essential functions:

• Pure sine wave inverter (230V AC output)
• Adaptive 35A battery charger
• Automatic high-speed transfer switch (16A)

This makes it a complete power hub for mobile and off-grid electrical systems.

POWERASSIST TECHNOLOGY

One of the key features is Victron’s PowerAssist, which prevents overload of limited AC sources such as:

• Small generators
• Shore power connections
• Weak campsite supplies

If demand exceeds supply, the MultiPlus automatically supplements power from the battery, ensuring uninterrupted operation.

SMART CHARGING SYSTEM

The built-in charger uses adaptive multi-stage charging to extend battery life and improve performance.

Compatible with:

• Lithium (LiFePO₄)
• AGM
• Gel
• Lead-acid batteries

Charging current: 35A

RELIABLE AC TRANSFER SWITCH

The integrated transfer switch automatically switches between inverter power and external AC power in milliseconds, ensuring seamless operation without interruptions.

Perfect for:

• Campervan shore power setups
• Boats with hybrid power systems
• Off-grid backup systems

EXPANDABLE SYSTEM DESIGN

The MultiPlus is part of Victron’s modular ecosystem:

• VE.Bus communication enabled
• Parallel operation possible (for higher power systems)
• Can be integrated with Cerbo GX for remote monitoring
• Configurable via VEConfigure or GX systems

This makes it scalable for future upgrades.

IDEAL FOR CAMPERVAN & OFF-GRID USE

This model is widely used in compact mobile energy systems such as:

• Campervan electrical installations
• Motorhomes
• Marine systems
• Small off-grid cabins
• Auxiliary power systems

Its compact size makes it ideal for limited installation space.
