What's the reasoning behind two different battery banks at different
voltages? What is the other equipment involved: batteries type, age,
inverters, etc.?

How big of a system are you looking at as some of the smaller charge
controllers are auto sensing

Wrenches,
I have a client that wants to charge a 24v battery bank and a 48v
bank with the same array. Different charge controllers, with some
type of relay is what I was thinking, and using the controller's
aux. 12v output for the relay control.
The primary battery to be charged would be the 24v bank, then once
it is fully charged, divert the pv to the secondary controller at
the 48v bank.
Any comments or recommendations on this would be helpful.
