Product Details

The Victron Quattro-II 48/5000/70-50/50 (230V) is built for those who need dependable, uninterrupted power. Whether you’re running an off-grid home, hybrid solar installation, or a marine or mobile system, the Quattro-II intelligently manages power from multiple sources to keep your setup running efficiently.

This powerful 5000 VA inverter and 70 A charger combination allows you to use power from solar, batteries, shore power or a generator — whichever is available. With two AC inputs, it automatically switches between power sources without interruption, ensuring your equipment never stops.

Victron’s PowerAssist technology prevents overloads by supplementing your AC power with energy from the battery when demand is high. At the same time, ESS (Energy Storage System) compatibility lets you store solar energy for later use or reduce grid consumption during expensive peak hours.

For larger systems, multiple Quattro-II units can be connected in parallel or configured for three-phase operation, offering the flexibility to scale as your energy needs grow.
