This sophisticated technology not only delivers rapid and efficient charging but also intelligently optimizes the charging process to significantly extend the lifespan of your valuable battery bank. Invest in longevity and reliability for your power storage.

Scalability and Future-Proof Design

Your power needs can evolve, and the MultiPlus-II is designed to evolve with them. Ready for expansion, this powerful unit supports both parallel and three-phase configurations, allowing you to seamlessly scale your system as your requirements grow. Build a foundation of power that can adapt to tomorrow's demands, today.

A Legacy of Innovation

Please note: For a brief period, this innovative product was known as the MultiGrid-II. Rest assured, it's the same cutting-edge technology, simply with an updated name reflective of its broader capabilities.

Unique PowerAssist Feature

The MultiPlus will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.

ESS: Energy Storage Systems

The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters. For examples and more detailed information see the ESS (Energy Storage System) manual.

Uninterrupted AC Power (UPS)

In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.

Remote Monitoring and Control

When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backup generator and more…
