Since the Quattro II 48/10000 isn't available, I plan to install 2 Quattro II 48/5000 in parallel (or get my boatbuilder to do it, who is a certified Victron installer) controlled by a Cerbo GX.
I know about how they need to be installed and configured (master/slave), but it's not clear how/whether you can use only one, for example to give redundancy in case one fails, or to reduce quiescent draw when power requirements are low.
Is it possible to just turn one (the slave?) off -- and if so, how (with the hardware switch on the unit?), or will the system then signal a fault?
If the system is reconfigured to from master/slave to a single unit, what has to be disconnected/isolated on the unused one -- mains inputs (shore and generator), 48V bus, 230V outputs, or all of the above?
Can this reconfiguration be done from the Cerbo or does it need to be done from a PC via the VE.bus and a smart dongle or USB interface?
