Victron MultiPlus-II 48/5000/70-50 GX Inverter

The Victron MultiPlus-II 48/5000/70-50 GX is a premium, multi-functional hybrid inverter and charger designed specifically for robust energy storage systems (ESS), off-grid installations, and grid-tied backup applications. By integrating the proven inverter/charger topology of the MultiPlus-II with an intelligent GX communication center, this unit drastically simplifies installation, reduces wiring complexity, and saves valuable wall space. The built-in GX functionality provides an all-in-one networking solution that seamlessly coordinates your inverter, solar charge controllers, and battery management system without requiring an external control screen.

Equipped with advanced PowerAssist and PowerControl technologies, the MultiPlus-II prevents limited AC sources—such as a small generator or a restricted shore/grid connection—from being overloaded. It achieves this by automatically reducing the battery charge when an overload is imminent, and further supplementing the AC supply with battery power when peak demand exceeds source capacity. Additionally, its dual AC outputs allow for smart load shedding; the primary output offers full uninterruptible (UPS) functionality switching in less than 20 milliseconds, while the secondary auxiliary output operates only when AC grid or generator power is active, protecting your battery bank from heavy, non-essential loads.

The integrated GX control unit includes built-in Wi-Fi and Ethernet interfaces, alongside a variety of communication ports (BMS-Can, VE.Direct, and USB). This setup allows for immediate, detailed monitoring and control through the free Victron Remote Management (VRM) portal or app, giving you complete visibility over real-time system performance, battery state of charge, and historic consumption logs from anywhere in the world. It is fully compatible with a wide range of managed lithium-ion batteries and traditional lead-acid banks.
