Looking at power for a future electric/series hybrid boat, plan to use a Quattro 48/10000 (plus a 10kVA generator) with 30kWh LiFePO4 battery bank for main propulsion system and 230V supply to mains appliances.
However when the boat is unoccupied and off-grid the Quattro consumes quite a lot of power (60W spec, people have reported up to 100W which is 2.5kWh/day), too much to be recharged from solar and more power than the loads which will be connected.
In this case the 230Vac loads will be relatively low -- freezer, Cerbo GX/Touch 50, wireless router for remote access/control, alarm and so on -- so I'd like to use something like a Phoenix 48/1200 to power these, since zero-load power is only about 10W. I can see two ways of doing this:
1. Connect both to same 230Vac supply and switch between Quattro and Phoenix using Cerbo GX
2. Have separate "always-on" 230Vac supply to just these appliances from Phoenix and just turn Quattro off when not needed
Will option #1 (easiest for wiring) work? Will the Quattro output have to be physically disconnected (switch? contactor?) from the 230Vac when it's turned off or can it be left connected when the Phoenix is turned on? Same question for the Phoenix, left connected or disconnected? Can the Cerbo control the switchover? How big a "dead time" (no power") will there be if changeover is done by enabling/disabling Quattro/Phoenix (can't have both on in parallel) at the same time?
Has anyone tried anything like this before?
