The Victron MultiPlus 12/500/20-16 is the smallest member of the MultiPlus family — 500VA of pure sine wave inverter output (430W continuous), 20A of multi-stage battery charger, and a 16A AC transfer switch. Sized for compact RVs, smaller boats, modest backup power, or any 12V system where you need basic AC capability without the cost or footprint of a full-size 2000–3000VA unit.
What 500VA powers
- LED lighting + small TV + laptop + phone charging simultaneously
- Small dorm-style refrigerator
- CPAP machine + reading light
- Single mid-size appliance (coffee maker OR microwave — not both)
- Small power tools (drill, light orbital sander)
- Office equipment (monitor + laptop + printer)
- Small entertainment center (TV + game console + sound bar)
Why the MultiPlus 12/500/20-16
- 500VA / 430W pure sine inverter — clean power for sensitive electronics
- 20A multi-stage charger — charges from shore or generator with proper battery care
- 16A AC transfer switch — automatic shore/generator transfer
- PowerControl + PowerAssist — boost limited shore power for peak loads
- Compact size — fits where larger MultiPlus units wouldn't
- VE.Bus networking — future-proof for system integration
- Multi-stage adaptive charging — AGM, Gel, Flooded, LiFePO4 profiles
- Quiet operation — minimal fan noise at low loads
