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.

<DIV>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 </DIV>

<DIV dir=ltr>Wrenches,<BR>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. <BR>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.<BR><BR>Any comments or recommendations on this would be
