<p dir="ltr">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. I set the volts and max amps where i wanted. Once the the AGM's get full the CC just stoped feeding it and instead it flows to the L-16's. Now if the L-16's are low in the AM, that CC will feed them first until current drops enough then its picked up by the AGM's. You will just have to try it to see but if you need put a contactor on the output thats voltage controlled. Untill you try it and get the CC's set it is hard to beleave but it works<br>

<div><span><font face="Arial" color="#0000ff">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.

<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
