Victron MultiPlus 12/2000 80-50 120V VE.Bus UL Listed Product Description
Victron MultiPlus 12/2000/80-50 - Professional Marine Inverter/Charger with UPS Function
Experience uncompromising marine electrical power management with the Victron MultiPlus 12/2000/80-50, a sophisticated combined inverter and charger designed for professional marine applications. This UL Listed unit delivers true sine wave AC power, adaptive battery charging, and advanced PowerAssist technology in one elegant, compact package perfect for boats, yachts, and off-grid installations.
True Sine Wave Inverter Performance
The MultiPlus generates clean, stable 120V AC power from your 12V battery bank with 2000VA continuous output (1600W at 77°F, 1400W at 104°F) and surge capability up to 3500W. The true sine wave output ensures compatibility with sensitive marine electronics, computers, and appliances while maintaining optimal efficiency and equipment protection.
Revolutionary PowerAssist Technology
Victron's exclusive PowerAssist feature prevents overloading of limited AC sources such as shore power connections or generators. The intelligent system automatically reduces battery charging when an overload would occur, then seamlessly boosts generator or shore power output using stored battery energy when additional power is needed. This technology maximizes the utility of limited power sources while maintaining system stability.
Uninterrupted Power Supply (UPS) Function
The MultiPlus provides seamless power continuity with transfer times under 20 milliseconds. When shore power fails or generator power is interrupted, the unit automatically switches to battery power so quickly that computers, navigation equipment, and other sensitive electronics continue operating without disruption. This critical feature ensures your vessel's systems remain powered during power source transitions.
Advanced Battery Charging Technology
Featuring Victron's renowned Adaptive Charge technology, the MultiPlus delivers up to 80 amps of intelligent charging current. The sophisticated 4-stage charging algorithm automatically optimizes the charging process based on battery condition:
- Bulk Phase: Maximum current charging for rapid battery restoration
- Absorption Phase: Voltage-regulated charging to achieve full capacity
- Float Phase: Maintenance charging to prevent overcharging
- Storage Phase: Extended float charging for long-term battery health

MultiPlus 12/2000 80-50 120V VE.Bus UL Listed
The MultiPlus, as the name suggests, is a combined inverter and charger in one elegant package. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, plus multiple system integration features.
Unique PowerAssist Feature
The MultiPlus will prevent the overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shoreside supply with power taken from the battery.
Uninterrupted AC Power (UPS function)
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
Virtually Unlimited Power Thanks to Parallel Operation
Up to 6 Multis can operate in parallel to achieve higher power output. Three-phase or split-phase operation is also possible. Please check our datasheets to see which models have parallel, three-phase, and split-phase capabilities.
Remote Monitoring & Control
When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop, or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto-starting a backup generator and more.
