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
Professional System Integration
VE.Bus Communication
The integrated VE.Bus communication system enables advanced monitoring and control when connected to compatible Victron devices. Monitor battery status, power consumption, and system performance remotely via smartphone, tablet, or computer using Victron’s free VRM portal and mobile app.
Parallel Operation Capability
Scale your power system by connecting up to 6 MultiPlus units in parallel, achieving output power up to 15kW/12kVA with 420 amps of combined charging capacity. Three-phase and split-phase configurations are also supported for larger installations requiring maximum power output.
