The Victron Energy MultiPlus-II GX combines the proven reliability of the MultiPlus-II range with the communication and monitoring capabilities of an integrated GX device, eliminating the need for additional equipment to manage the system. This all-in-one solution simplifies the configuration, monitoring and remote maintenance of photovoltaic installations, backup systems and off-grid applications.

Thanks to PowerAssist and PowerControl technologies, the MultiPlus-II GX optimises the use of available energy by preventing overloads on generators or limited AC supplies, while its ultra-fast transfer switch ensures uninterrupted power for critical loads in the event of a grid failure.

The integrated GX device enables the inverter/charger to communicate with smart batteries, MPPT solar charge controllers, PV inverters and other Victron Energy equipment, centralising all system information on a single platform. Integrated WiFi and Ethernet connectivity provide both local and remote access through the Victron Remote Management (VRM) platform, allowing users to monitor real-time data, modify system settings and receive system alarms.

Its compatibility with ESS (Energy Storage System) installations, grid-connected systems, off-grid applications and parallel or three-phase configurations makes the MultiPlus-II GX one of the most complete solutions for residential, commercial, industrial, marine and specialised vehicle installations.

Available in different power ratings and battery voltages, the MultiPlus-II GX range offers a flexible, scalable solution designed to meet the current and future requirements of professional energy installations.
