I have a Quattro 12 / 5000/ 220 set up to charge my lithium battery bank from shore power. I’d like to connect my portable generator (120V) to the Quattro to charge my batteries while anchored out. From the manual, it looks like I would just connect to the 2nd AC input (L1-2,N,GND). Is this correct? Do I need to modify the configuration via VEConfig to make this work?
