Quattro-II Inverters

Next-generation dual-input inverter/charger delivering true 2x120V split-phase output for demanding North American off-grid, mobile, and small-commercial power systems.

The Victron Quattro-II builds on the proven Quattro platform with improved conversion efficiency up to 96%, updated power electronics, and enhanced connectivity. Available in 12V/3000VA and 24V/3000VA 2x120V models, it provides two independent 120V line outputs (240V split-phase) plus two independent AC inputs with automatic transfer switching in under 20 milliseconds — seamless failover between grid, generator, and inverter power without external transfer switches.

PowerControl and PowerAssist manage limited shore or generator feeds and boost them with battery power under peak loads. Adjustable battery charge current (120A on the 12V model, 70A on the 24V model) suits a wide range of battery banks and chemistries. VE.Bus communication integrates with GX monitoring devices for full remote management, and Bluetooth access is available through an optional VE.Bus Smart Dongle for local diagnostics.

Used in Alchemy industrial power systems for residential and light-commercial backup, off-grid cabins, mobile platforms, and split-phase loads where dual AC inputs and 120/240V output are required.
