OK wrenches here me out, yes this does work simple path of least
resistance. I did this for a alarm system, 1 PV array connected to two OB
MX-60's both get the the same array leads and one went to AGM's and the
other went to FLA L-16's, mine were all 48 volt banks but i dont see that
being an issue
Interesting! I was head-scratching as to how to do an identical task. I'd think
a contactor on the HV PV output side suitably rated for voltage/current
triggered by the aux output once the Classic goes into float would do the
trick. I recall the Classic has that feature but never used it yet.
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 w
What's the reasoning behind two different battery banks at different
voltages? What is the other equipment involved: batteries type, age,
inverters, etc.?

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
