Victron MultiPlus-II 48V, 2000 & 5000, 120V

The Victron MultiPlus-II 48V, 2000 & 5000 120V is a powerful inverter/charger engineered to deliver dependable AC power and advanced battery charging for demanding off-grid and backup power applications. Designed for marine vessels, yachts, RVs, commercial vehicles, and stationary energy systems, it combines multiple essential functions into a single compact unit, simplifying installation while providing exceptional performance and reliability.

Intelligent PowerControl technology continuously monitors available shore or generator power, automatically limiting battery charging when necessary to prevent overload. When connected loads temporarily exceed the available AC supply, PowerAssist instantly supplements the incoming power with energy from the battery bank, allowing high-demand appliances to operate without tripping breakers or overloading a generator.

In the event of a utility or generator failure, the MultiPlus-II automatically switches to inverter operation in just milliseconds. This seamless transfer helps keep computers, communication equipment, security systems, and other sensitive electronics running without interruption, making it an excellent choice for backup power and energy storage applications.

The integrated battery charger features an adaptive charging algorithm that optimizes charging performance while helping maximize battery lifespan. As your power requirements grow, the MultiPlus-II is ready to expand through parallel operation or three-phase system configurations, providing a flexible solution for both current and future installations.

Note: For a limited period, this model was marketed under the name MultiGrid-II. Although the branding changed, it is the same trusted platform that continues to deliver the advanced performance and reliability expected from Victron Energy.

Features

Powerful 2000 & 5000VA Pure Sine Wave Inverter

The MultiPlus-II delivers a continuous 2000 or 5000VA(Based on Model) pure sine wave output, providing clean, stable AC power for sensitive electronics, appliances, and heavy-duty equipment. Its robust design makes it ideal for off-grid, backup power, marine, RV, and commercial energy systems.

Advanced Battery Charger with Adaptive Charging

An integrated high-performance battery charger uses adaptive charging technology to optimize charging based on battery condition. This improves battery health, shortens charging times, and extends the service life of lead-acid and compatible battery banks.

PowerAssist Prevents Overload

PowerAssist technology automatically supplements limited shore power or generator capacity with energy from the battery bank during peak demand. This prevents overloads and allows larger loads to operate without tripping circuit breakers.

PowerControl for Smarter Energy Management

PowerControl allows you to set a maximum current draw from shore power or a generator. The MultiPlus-II intelligently manages battery charging and connected loads to stay within the available power limit, helping protect electrical infrastructure.

Dual AC Outputs for Critical Loads

The unit features two AC outputs, with one dedicated to uninterrupted essential loads. During a grid outage, critical circuits remain powered almost instantly, while non-essential loads are disconnected to preserve battery capacity.

Fast UPS Functionality

With its ultra-fast transfer switch, the MultiPlus-II seamlessly transitions to inverter operation during power failures. Computers, networking equipment, medical devices, and other sensitive electronics continue operating with minimal interruption.

Parallel and Three-Phase Operation

Multiple MultiPlus-II units can be connected in parallel to increase total power output or configured for three-phase installations. This flexibility allows the system to grow as your energy requirements expand.

Seamless ESS Integration

Designed for Energy Storage Systems (ESS), the MultiPlus-II integrates seamlessly with solar installations and Victron GX monitoring devices. It helps maximize self-consumption, optimize battery usage, and improve overall energy efficiency.

Remote Monitoring and Configuration

When paired with a Victron GX device, the MultiPlus-II can be monitored and configured remotely through the Victron Remote Management (VRM) portal. Users can view system performance, receive alerts, and make adjustments from virtually anywhere.

Built for Professional Installations

Engineered for demanding marine, vehicle, and off-grid applications, the MultiPlus-II combines proven reliability with advanced protection features. Its durable construction and intelligent power management make it a trusted solution for professional energy systems.
