The Victron Quattro-II 24/5000/120-50/50 230V is the next generation of the proven Quattro series – designed for maximum flexibility, efficiency, and reliability in demanding energy systems.
It combines a pure sine wave inverter, a powerful battery charger, and automatic mains changeover in one compact unit.
The Quattro-II has two AC inputs (e.g., grid and generator) and can automatically switch between sources to ensure a continuous power supply.
The PowerAssist function actively supports the mains power supply: during peak loads, the Quattro-II switches energy from the battery to prevent the mains source from being overloaded.
The PowerControl function also allows the maximum input current to be limited, which is particularly advantageous when mains or generator power is limited.
The device can be integrated into complex systems via the VE.Bus interface and networked with other Victron components such as the Cerbo GX or Color Control GX.
This makes the Quattro-II ideal for use in photovoltaic, marine, off-grid, and backup applications.
