Victron Energy MultiPlus-II 48V 3000VA Inverter Charger 120V (35A Charge / UL Certified) – PMP482305102

The MultiPlus-II is a multifunctional inverter/charger that combines a powerful true sine wave inverter, advanced adaptive battery charger, and high-speed AC transfer switch in a single compact enclosure. It features intelligent power management with PowerControl and PowerAssist functions, helping prevent overloads on generators, shore power connections, and other limited AC sources.

In the event of a grid failure or when shore or generator power is disconnected, the inverter automatically activates and takes over the power supply in less than 20 milliseconds, ensuring uninterrupted operation of computers and other sensitive electronic equipment.

• Multifunctional inverter/charger with intelligent power management
• Powerful true sine wave inverter output
• High-speed AC transfer switch with less than 20ms transfer time
• Two AC outputs for flexible load management
• External current sensor option extends PowerControl and PowerAssist functionality up to 100A
• Remote monitoring and configuration capability when connected to a GX device

• Main AC Output: No-break functionality with transfer time below 20 milliseconds, ideal for computers, communication equipment, and sensitive electronics.
• Secondary AC Output: Active only when external AC power is available, preventing unnecessary battery discharge for non-essential loads such as water heaters.

• Supports parallel operation for increased power capacity.
• Up to 6 MultiPlus units can operate in parallel.
• Provides up to 15kW / 18kVA output power.
• Delivers up to 420A charging capacity.

Supports three-phase power supply configurations using three units.

Allows operation with limited generator, shore, or grid power. The system automatically prioritizes connected loads and uses only available excess power for battery charging, preventing source overload.

Boosts available generator or shore power by supplementing it with battery power during periods of high demand. This helps meet temporary peak loads without overloading the external AC source.

• Advanced four-stage adaptive charging system.
• Dual-bank battery charging capability.
• Automatically adjusts charging parameters based on battery condition.
• Includes extended float charging stage for optimal battery maintenance.

Quick and easy setup using integrated DIP switch settings. Most configuration changes can be completed within minutes after installation.

When connected to Ethernet and a compatible GX device, the system can be remotely monitored, configured, and controlled.
