Victron Energy MultiPlus 48/3000/35-16 230V VE.Bus Inverter/Charger

Victron Energy MultiPlus 48/3000/35-16 230V VE.Bus Inverter/Charger

The Victron Energy MultiPlus 48/3000/35-16, as the name suggests, brings together a powerful true sine wave inverter, a sophisticated adaptive battery charger, and a high-speed AC transfer switch into a single compact enclosure. Designed for rigorous off-grid, marine, and mobile applications, this 48V unit delivers clean, stable 230V AC power while ensuring connected batteries are charged efficiently. With a robust 3000VA capacity and advanced system integration capabilities, the MultiPlus serves as a highly reliable foundation for complex power architectures.

Uninterrupted AC Power and Robust Performance

At the core of the MultiPlus 48/3000/35-16 is a high-performance pure sine wave inverter capable of delivering 2400W of continuous power at 25°C. Built to handle demanding electrical requirements, it features an exceptional peak power rating of 6000W, which is crucial for starting high-inrush loads such as air conditioners, heavy power tools, and refrigeration compressors. When grid or generator power is disconnected, the integrated 16A transfer switch activates in less than 20 milliseconds. This near-instantaneous switchover ensures that sensitive electronics, computers, and critical appliances remain powered without any disruption or reset.

Intelligent PowerControl and PowerAssist Technologies

Managing limited AC sources is a common challenge in marine environments and off-grid setups. The MultiPlus addresses this directly through its advanced PowerControl and PowerAssist functions. PowerControl allows a maximum generator or shore power current to be set. The unit will then prioritise AC loads and use only the surplus energy for battery charging, preventing the external AC source from becoming overloaded.

Taking this a step further, PowerAssist technology actively supplements the capacity of a limited alternate source. Where peak power is often required only for a limited period, the MultiPlus will compensate for insufficient shore or generator power by drawing seamlessly from the 48V battery bank. Once the heavy load reduces, the spare power is redirected back to recharge the batteries.

• High Power Output: Delivers 3000VA (2400W continuous) and an impressive 6000W peak power for starting heavy electrical loads.
• Adaptive Battery Charging: The integrated 35A charger features advanced adaptive technology to optimise battery health and extend operational lifespan.
• Fast Transfer Switch: A 16A automatic AC transfer switch transitions power sources in under 20 milliseconds, keeping sensitive equipment running smoothly.
• PowerAssist Functionality: Temporarily draws from the battery bank to prevent generator or shore power supplies from overloading during peak demand periods.
• Seamless Integration: Equipped with a VE.Bus communication port for advanced setup, multi-unit synchronisation, and comprehensive system monitoring.

Advanced Adaptive Charging

The 35A adaptive charger incorporates variable charge curves that automatically adjust to the way the battery is being used. This adaptive feature ensures that during periods of shallow discharges, the absorption time is kept short to prevent overcharging. Following a deep discharge, the absorption time is automatically increased to ensure the battery is completely recharged. This intelligent approach maximises charging efficiency and prolongs overall battery life across various chemistries.

Scalability for Evolving Power Demands

As power requirements grow, the Victron MultiPlus is built to scale alongside them. Through the VE.Bus communication port, up to six MultiPlus units can be connected in parallel to achieve significantly higher power output and charging capacity. For industrial applications or larger off-grid installations, multiple units can also be configured to provide three-phase or split-phase power. This flexibility ensures the foundational hardware remains relevant even if the overall system architecture changes over time.

System Configuration and Remote Monitoring

To gain complete control over the energy system, the MultiPlus pairs seamlessly with Victron GX devices, such as the Cerbo GX. When connected, the system can be monitored locally or accessed remotely from anywhere in the world via the free Victron Remote Management (VRM) portal. Installation and initial configuration are streamlined through the VE.Bus platform, providing the user with detailed insights and management options over the entire energy grid.

Designed with safety and durability at the forefront, the Victron Energy MultiPlus 48/3000/35-16 includes comprehensive protection against short circuits, over-temperature, and irregular voltage inputs. It stands as an exceptional solution for applications requiring dependable off-grid power, intelligent charging, and continuous power continuity.
