Im doing some DC work on my boat will disconnect the quattro from the DC circuit. Will the Quattro still switch ok between the shore pwr and genset inputs? Does it need DC power for any functions? Thanks

Quattro with only AC input/output
If there is no DC input, it will only start up if ACin1 is present, but it will work okay from there. It will not start up if only ACin2 is present.
I suspect it will not be able to switch back and forth without DC, because it just flips some relays internally, and there must be a small point of time when neither AC input is switched into the circuit.
Interesting. So AC2 is not considered a "valid" input until the unit sees DC?
Do you think that's a software or physical limit? Seems kind of odd for it to be done on purpose?
Thanks!
Quattro may be different from other inverters ....
Most inverters use the DC for all control and protection facilities.
Therefore if DC is turned off the inverter/charger will be destroyed, perhaps not on the first event but sooner or later....

This is a common problem. How do you keep the AC flowing when you have to do maintenance on your system. The solution is external to the Inverter/Charger system and requires rewiring the shore power input circuits. Below is a schematic of my system, note the "By-Pass" circuitry in the AC Load/Distribution panel on the left side of the schematic.

Forgot to add a power flow diagram for my Blue Seas panel that may be clearer.

Thanks guys, very helpful.
