When connected to a 120\/240V split-phase source, it passes through both lines at full 50A capacity for charging and AC loads. Switch to a single-phase 120V input, and the Quattro-II intelligently combines L1 and L2 outputs, ensuring both sides of your distribution panel receive 120V power.\u003c\/p\u003e\n\n\u003cp\u003eIn inverter mode, the Quattro-II internally bridges both output lines, delivering 120V to every circuit in your panel - guaranteeing consistent power availability throughout your installation. The dual AC input accepts shore power and generator connections with automatic source switching, while PowerAssist and PowerControl prevent overloads and optimize energy usage. This is the definitive solution for RVs, marine vessels, and off-grid homes with standard 50A service panels.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual AC Inputs with Auto-Switching\u003c\/strong\u003e - Accepts two independent AC sources (shore power, generator) and automatically connects to the active source for seamless redundancy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2x120V Split-Phase Design\u003c\/strong\u003e - Purpose-built for North American 50A 120\/240V split-phase applications, passing through both lines at full capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntelligent Line Management\u003c\/strong\u003e - On single-phase 120V input, L1 accepts incoming power while both L1 and L2 outputs deliver 120V.
