Victron Energy MultiPlus 12/500/20-16 120V VE.Bus — Compact Power, Smart Control

When space is limited but performance can’t be compromised, the Victron Energy MultiPlus 12/500/20-16 120V VE.Bus delivers the perfect blend of efficiency, intelligence, and reliability. Designed for small RVs, marine systems, and compact off-grid installations, this all-in-one inverter/charger ensures seamless energy management wherever you go.

Like every Victron Energy MultiPlus model, it combines three essential systems into one: a pure sine wave inverter, an adaptive battery charger, and a high-speed transfer switch. The result? A single, compact solution capable of powering, charging, and protecting your entire 12V electrical system.

Multifunctional, with Intelligent Power Management

The MultiPlus 12/500/20-16 provides smooth AC power from your batteries while automatically switching to shore or generator input when available. Its intelligent power management ensures continuous, clean energy — even in the toughest off-grid conditions.

This unit integrates advanced inverter control with adaptive charging algorithms, allowing the system to automatically balance energy between your power sources and loads.

Parallel Operation and Three-Phase Capability

Need more power? The MultiPlus can scale up easily.

• Parallel operation: Connect up to six MultiPlus units to increase total output power.
  
• Three-phase capability: Configure three units for full three-phase operation, ideal for high-demand or industrial setups.
  

PowerControl – Managing Limited Shore or Generator Power

When connected to limited shore power or a small generator, PowerControl allows you to set a maximum current draw. The MultiPlus then monitors all connected AC loads, automatically adjusting charge current to prevent overloads. This ensures you stay within safe power limits while still charging your batteries efficiently.

PowerAssist – Boosting Generator or Shore Capacity

Victron’s exclusive PowerAssist technology takes PowerControl even further. When a sudden demand spike occurs — like starting a microwave, compressor, or power tool — the MultiPlus instantly supplements your available shore or generator power with battery energy. Once the load drops, it reverts to charging the batteries again.

This dynamic balancing prevents tripped breakers and guarantees continuous power flow even under fluctuating loads.

Four-Stage Adaptive Charger with Dual Battery Charging

The Victron Energy MultiPlus 12/500/20-16 includes a four-stage adaptive charger designed to maximize battery performance and lifespan.

• Automatically adjusts charge voltage and current based on battery type and condition.
  
• Compatible with Lithium, Sealed, AGM, Gel, and Flooded batteries.
  
• Includes a second trickle-charge output for maintaining starter or auxiliary batteries.
  

This ensures your batteries are always charged efficiently — without overcharging or sulfation.

High Start-Up Power

Some inverters struggle with devices that require high inrush current, such as LED power supplies, halogen lamps, or small power tools. The MultiPlus delivers high surge capacity, ensuring reliable startup for all your demanding appliances.

Search Mode for Energy Efficiency

When operating in inverter mode with no active load, Search Mode reduces power consumption by up to 70%. The inverter switches off during idle conditions and reactivates automatically when load is detected — a smart feature that conserves battery energy for longer runtime.

Programmable Relay for Custom Control

A built-in programmable relay gives system integrators additional flexibility. By default, it acts as an alarm relay (triggering in case of low voltage, high ripple, or over-temperature), but it can also be configured for custom control functions via VE.Configure software.

On-Site and Remote Configuration Options

The MultiPlus 12/500/20-16 is ready to go right out of the box, with basic settings adjustable via DIP switches for battery charge voltage, search mode, or remote control. For advanced configuration and firmware updates, use:

• VictronConnect App (Bluetooth-enabled)
  
• VE-Configure software via MK3-USB Interface
  

For remote monitoring and full system visibility, connect the MultiPlus to a Victron Cerbo GX MK2 System Monitor. The Cerbo GX links your system to the Victron Remote Management (VRM) portal, allowing you to view live power data, battery health, and performance analytics from anywhere.

Compact Power with Professional Reliability

The Victron Energy MultiPlus 12/500/20-16 is ideal for:

• Compact RVs and camper vans needing efficient power conversion.
  
• Small marine systems requiring reliable inverter/charger performance in tight spaces.
  
• Emergency vehicles or service trucks where stable, uninterrupted power is critical.
  
• Remote monitoring setups using the Cerbo GX for system control.
