Victron Energy MultiPlus 500VA - 1200VA - 12v only
Victron MultiPlus 500VA–1200VA – Compact Power with Big Performance
The Victron MultiPlus 500VA, 800VA, and 1200VA inverter/charger models pack all the performance and smart features of the larger MultiPlus units into a compact, lightweight design—perfect for smaller off-grid, mobile, and marine applications where space and efficiency are key.
Each unit combines a pure sine wave inverter, an advanced adaptive battery charger, and a fast automatic transfer switch in one enclosure, delivering seamless AC power and precision battery management. Whether you’re running a small RV, sailboat, service vehicle, or remote worksite, these MultiPlus units provide dependable power you can trust.
With PowerAssist technology, the MultiPlus automatically supplements shore or generator power during peak demand, preventing overloads. When loads drop, it uses the spare power to recharge your batteries, keeping your system balanced and ready. The adaptive 4-stage charging process maximizes battery health for lithium, AGM, gel, or lead-acid batteries.

Multifunctional Power Management in One Compact Unit
The Victron MultiPlus is an all-in-one solution that combines:
- True Sine-Wave Inversion for clean, reliable AC power
- Adaptive Battery Charging that automatically adjusts its four-stage profile to optimize any battery type
- High-Speed AC Transfer Switching for seamless change-over between shore/generator power and inverter output
Advanced Capabilities
Parallel & Three-Phase Operation
- Connect up to six units in parallel to increase your total power output
- Configure three devices for true three-phase service
PowerControl
Limit shore or generator current to prevent overloads. The MultiPlus intelligently balances your AC loads and battery charging to stay within your set threshold.
PowerAssist
When peak demand exceeds your shore or generator supply, PowerAssist draws extra power from your batteries. As demand falls, the system replenishes the battery—delivering uninterrupted performance.
Dual-Bank, Adaptive Charging
- Four-stage charging automatically fine-tunes itself for Lithium, AGM, Gel, Flooded, and Sealed batteries
- Dedicated trickle-charge output for a starter battery
High Start-Up Power
Handles heavy inrush loads—like LED drivers, power tools, and halogen lamps—without faltering.
Search Mode
In inverter mode with no load, power consumption drops by up to 70 %. The unit “wakes” briefly every two seconds and only remains on if a minimum load is detected.
Programmable Relay
Factory-set as an alarm relay (high temperature, input ripple, or low battery), but fully configurable for custom control logic.
Remote Control & Monitoring
- On-site adjustments via DIP switches or VictronConnect/VE-Configure (with the MK3-USB interface)
- Full remote management through a Cerbo GX or other GX product, with data logging and live dashboards on the free VRM portal
The MultiPlus is ready to go straight out of the box—providing professional-grade power conversion, charging, and intelligent load management for mobile, marine, and off-grid applications.
