Quattro II – Enhanced Dual AC Input Technology

The Victron Quattro II represents the next generation of dual AC input inverter-charger technology, building upon the proven Quattro platform with enhanced features and improved performance. This advanced system combines inverter, battery charger, and dual automatic transfer switch functionality with sophisticated power management capabilities. The Quattro II accepts two separate AC sources, automatically selecting the optimal input while maintaining seamless power delivery to connected loads.

The Quattro II product line includes models from 5kVA to 10kVA with 48V DC input configurations. Split-phase 120V/240V output serves North American residential and commercial applications. Enhanced PowerAssist technology supplements insufficient AC input with battery power, preventing source overload during peak demand. The improved charging algorithms optimize battery health across LiFePO4 and lead-acid chemistries with temperature-compensated parameters.

Quattro II systems support parallel configurations for increased capacity and redundancy. VE.Bus communication integrates with GX monitoring devices, enabling comprehensive system visualization and remote management through the VRM portal. Advanced features include programmable relay outputs, adjustable input current limits, and frequency shifting for grid-support applications.

The Quattro II includes upgraded components for extended reliability and meets current safety certifications for residential ESS installations.
