I am building a solar system with main components quattro,, ccgx and 48V BYD batteries. This feeds two circuits, one prioritised always on and the other only on when there is plenty of charge in the batteries. My thinking is that a relay either in the quattro or ccgx can drive a contactor which switches the non priority circuit. The loads will be LED lighting, computers and personal electronics.It appears that the victron relays have a maximum voltage of 60V so a contactor with a 48V dc coil should be OK. It wasn't easy but I found the Schneider LC1D40AED which would fit the bill. It is 3p when I only need 2 and it is also hard to come by and I would like it asap.
I am a newcomer to the Victron world (but enjoying it) and there might be a slicker easier solution out there.
I would be very grateful for any guidance from anybody with experience.
Thank you
