HI Carl and everyone, I was just a little to quick in
my answer.  When you do positive ground, YOu Ground
the battery, and the Array frame, and the MX60 frame. 
BUT NOT Ground the positive from the modules only the
Positive of the Battery (which is grounded at the
Tele-com site)  Again do not ground the array
positive, as this will by pass MX60 which does its
boost operation on the positive circuit through the
controller.  

good luck
Darryl
