Victron Energy | MultiPlus-II 48/5000/70-95 120V, Pure Sine Wave Inverter/Charger
Victron MultiPlus-II 48/5000/70-95 120V Pure Sine Wave Inverter/Charger
The MultiPlus-II 48/5000/70-95 120V is Victron Energy’s next-generation inverter/charger, combining the advanced features of the MultiPlus and MultiGrid into a powerful, flexible system component. Designed for both off-grid and grid-interactive systems, the MultiPlus-II is ideal for residential and commercial energy storage applications.
The MultiPlus-II inherits all the capabilities of the original MultiPlus, such as true sine wave inversion, adaptive battery charging, and hybrid PowerAssist technology. It also integrates anti-islanding protection and a wide range of country-specific grid approvals from the MultiGrid series.
It supports an external current transformer (optional), enabling PowerControl and PowerAssist functions with precise load management and optimized self-consumption up to 32A.
Key Features
PowerAssist – Prevent AC Source Overload
-
Automatically compensates for peak power demands by drawing supplemental energy from the battery bank.
ESS Compatible – Energy Storage Systems
-
Seamlessly integrates into grid-tied solar energy systems for self-consumption, time-of-use shifting, and backup.
Uninterrupted Power Supply (UPS Mode)
-
In the event of a grid failure or power source disconnection, the MultiPlus-II ensures seamless switchover to inverter mode (within 20 milliseconds), maintaining continuous power to critical loads.
Remote Monitoring & Control
-
Monitor and manage system performance from anywhere in the world via the Victron Remote Management (VRM) portal, when connected to a GX device (e.g., Cerbo GX).
-
Adjust settings, start/stop backup generators, and analyze detailed energy data using a computer, smartphone, or tablet.
Grid Compliance & Country Approvals
-
Integrated anti-islanding protection and compatibility with multiple grid standards make the MultiPlus-II suitable for a wide range of energy applications globally.
