    Yep. No problem. :D

    Many systems have multiple controllers and arrays. Sometimes getting the different controllers to agree on Voltage and set points is tricky. MidNite's "Follow Me" function (usable with multiple Classic controllers) works best. But mixing PWM and MPPT can be done too.

    Another recommendation with multiple charge controllers is to make sure each charge controller goes to the battery bus with its own set of cables...

    Do not share one set of cables from the battery bus to the two charge controller (two or more controllers sharing a single set of wiring can confuse each other).
