DESCRIPTION
Victron MultiPlus-II 48/4k5/55-32 230V Inverter/Charger
More power per kg and per dm³, and better high temperature performance compared to other MultiPlus-II models.
Professional-Grade Inverter/Charger with ESS Functionality
The Victron MultiPlus-II 48/4k5/55-32 230V is a multifunctional inverter/charger engineered for professional marine, mobile, and off-grid applications. It combines a high-efficiency 230V inverter with a powerful battery charger, featuring Energy Storage System (ESS) functionality that allows seamless integration with solar, generator, and grid-connected systems. With peak power capabilities of 7kW and time-limited output of 4.5kW for 2 hours, it ensures continuous power supply even during high-demand conditions.
PowerControl and PowerAssist – Intelligent Load Management
PowerControl allows the MultiPlus-II to limit AC input current to a safe value, preventing grid or generator overloads. PowerAssist extends this functionality, compensating for insufficient generator or shore power with energy from the battery during peak load periods. Once demand decreases, the surplus energy is used to recharge the battery, maximising energy efficiency and system reliability.
Uninterrupted Power & Dual AC Outputs
The main AC output provides seamless transfer during grid or generator failure in less than 20 milliseconds, maintaining continuous operation of sensitive electronics. A second AC output is live only when input power is available, ideal for non-critical loads such as water heaters. Both outputs are fully integrated into the PowerControl and PowerAssist system for intelligent energy distribution.
Flexible System Configuration
The MultiPlus-II 48/4k5/55-32 supports parallel operation for increased output and three-phase setups for larger installations. Up to six units can be configured in parallel, or three units for three-phase operation, and up to six sets of three can operate in parallel. On-site configuration is simple with VEConfigure software, while monitoring can be performed via Cerbo GX, Ekrano GX, Digital Multi Control Panel, or VictronConnect for real-time insight.
High Efficiency & Robust Design
With a maximum efficiency of 95%, the MultiPlus-II minimizes energy loss while delivering reliable power. Its rugged IP21-rated steel enclosure and fan-assisted cooling ensure safe operation in temperatures ranging from -40°C to +65°C. The unit supports lithium, lead-acid, and zinc-bromine batteries, making it highly versatile for various energy storage solutions.
Applications
- Marine and yachting systems for uninterrupted AC power
- Mobile and vehicle energy solutions
- Off-grid homes and commercial installations
- Solar PV integration and energy storage systems
- Professional backup power for critical loads
Upgrade your system with the Victron MultiPlus-II 48/4k5/55-32 230V for intelligent energy management, peak load support, and uninterrupted AC power for professional and off-grid applications
