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
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.
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.
Thanks guys, very helpful.
