Description
The Victron Quattro-II 12/3000/120-50/50 2x120V combines a 3000VA pure sine wave inverter with a 120A adaptive battery charger, making it the ideal solution for split-phase power systems. Its dual AC inputs allow it to seamlessly manage power from shore connections or generators, automatically switching to the most reliable source.
With PowerAssist technology, the Quattro-II prevents overloading of shore or generator power by supplementing energy from the battery when needed. In inverter mode, it ensures a stable 120V output and can operate in parallel or three-phase configurations, making it highly scalable for larger power systems.
Additionally, when connected to a Victron GX device (e.g., Cerbo GX), the system can be monitored and controlled remotely via the Victron VRM portal, providing real-time insights and management options from anywhere in the world.
