Was wondering that myself tom, but thought I'll let you come round to it
Unless. his intella power panel controlls his intella switch,, That might be the case
I don't know those systems well enough to say one way or the other
I just got done fixing my Xantrex Prosine (Returned for warranty exchange) Got the new one in, hooked up, turned on, no smoke, no sparks, no fire, no output (oh well) Pulled the wireing cover off and found the wire that I forgot to connect, suddenly I had no smoke, no sparks, no fire and no beeps from the down-stream power fail alarm (In short, OUTPUT)
Checked, found it was putting amps into the batteries (Good) pulled the breaker down the hall that feeds it and the amps suddenly started coming OUT of the battery (With no errors) also good. Went back today and fniished the install (Covers, lock down the fuse holder) all I need now is the battery bridge switch for when I wish to hook up ALL the batteries
