It is a 24VDC model, run of a battery bank that is charged through an outback inverters connection to the grid. So the battery voltage is always at 24V. The tracker will run fine for a couple days then it will get stuck in the east facing direction. I can make it track by switching the control box to "Manual Control Mode" and then moving the array in any direction for a second or two and then switching it back to "Automatic Control Mode". It will then track for a couple days and get stuck in the east direction again. <BR><BR>Everything is greased regularly, and the voltage at the motors is always where it needs to be. I haven't noticed anything binding the tracker in the east direction and it seems like to sensor is fine because it tracks after I use the steps I described above to move it. <BR><BR>Any thoughts?<BR><BR>Thanks as always,<BR><BR>Jesse <BR><BR>Sent from my iPhone<BR>_______________________________________________<BR>List sponsored by Redwood Alliance<BR><BR>List Address: RE-wrenches@lists.re-wrenches.org<BR><BR>Change listserver email address & settings:<BR>http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org<BR><BR>List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html<BR><BR>List rules & etiquette:<BR>www.re-wrenches.org/etiquette.htm<BR><BR>Check out or update participant bios:<BR>www.members.re-wrenches.org<BR><BR></BODY></HTML>
