You’re welcome, richschafer, and thanks for posting your experience and photo here.
As mentioned in the beginning of this thread, I wanted to illustrate my experience in replacing my Parallax converter with the Xantrex unit and that this thread was not intended to be “instructions” per se.
My converter replacement was based, however, on instructions found in the illustrated article, “Parallax 7355 Converter Replacement with Xantrex XADC-60
”, written by Ernie Hensley (28’ 2005 Safari) and found on bestconverter.com
Regarding ½” mounting rails
Ernie also noted that using 5/8” aluminum channel on both sides was too tight and he ended up using a ½” wide rail on one side and a 5/8” wide rail on the other. In his “Some final thoughts & lessons learned section” he recommends using ½” aluminum channel on both sides and add a washer if necessary to take up any lateral movement. (I did not need to use a washer.)
Regarding wire size:
Xantrex’s Installation Instructions, page 24, Table 2, does show that Xantrex recommends a minimum DC wire gauge of 6 AWG (for XADC-60) running to the battery bank
(and a maximum length of 20 feet). It notes that using larger run lengths or smaller gauge wires [to the batteries] than recommended will result in decreased charge/load output performance as well as additional heating and interference effects.
The large red and white wires that Airstream used to connect my OEM converter to my two AGM batteries seem proper and can be seen attached to the DC panel in the enlarged photo in post #5
of this thread.
Table 1 (on page 24 of Xantrex Installation Instructions) lists torque requirements for terminal connections for various sized wires, including 10 AWG.
Upon completion of the installation and connection to shore power, Xantrex put out 14.2 volts as read by my voltmeter (seen in post #11
of this thread), which corresponds to the bulk or first stage charging. This was followed by the absorption or second stage, and finally, once the batteries were fully charged, it settled down to 13.4 volts, the float or third stage of charging.
My Xantrex XADC-60 continues to function perfectly and quietly. I am very happy with it and the service from bestconverter.com
