Keep in mind that the Midnite controller has a combined PV and bat.
negative and the Blue Sky requires isolated PV and bat. negative.

The thought was to charge the batteries for a new building utilizing
an SW4024 with new classic controller and new L A batteries, and once
those batteries are charged send the PV to the house system which is
the 48v setup with dual outback inverters and dual SB3048 CCs. Lead
acid batteries as well. 3 years old
I've never had this come up in 16 years!

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.
