Packed with intelligent energy features like PowerAssist, PowerControl, and UPS functionality, the MultiPlus 12/3000 UL ensures seamless operation even in demanding environments — all while maximizing battery life and reducing power loss.

Inverter, Charger & UPS in One Integrated Device

This advanced 12V power unit includes:

• Pure Sine Wave Inverter – Delivers 3000 VA / 2400 W continuous (6000 W peak)
• High-Output Charger – Charges at up to 120 A, supports GEL, AGM, and LiFePO₄ batteries
• Uninterruptible Power Supply (UPS) – Automatically switches to battery during grid outages

Whether you're powering air conditioners, tools, or sensitive electronics, the MultiPlus delivers stable AC power and smart charging, even in remote or mobile setups.

Smart Power Management with PowerAssist & PowerControl

• PowerControl – Limits the maximum current draw from a generator or grid to avoid overload
• PowerAssist – Automatically supplements shore or generator power with battery energy when demand spikes
• Programmable Relay & Dual Outputs – Customize power flows and prioritize loads

These features allow for safe, stable operation even with limited shore power or small generators.

Remote Monitoring & Full System Integration

The MultiPlus integrates seamlessly into Victron’s ecosystem:

• VE.Bus Communication – Enables parallel and 3-phase operation, remote control, and full ESS compatibility
• Compatible with GX Devices (e.g., Cerbo GX) for local + remote monitoring via Victron VRM Portal
• Adjustable Charging Profiles – Includes absorption, float, and storage charging modes, plus temperature compensation

Great for advanced off-grid, grid-tied, or mobile solar systems where visibility and control matter.
