<p>Mac, which mode is being confused elevation or azimuth. What have you replaced and what does Jeff Grulic say of Wattsun?</p>
<p>The photo sensor I like is the single axis. There really is little need to use the dual axis for offgrid, in my opinion.</p>

<div dir="ltr">Hi Wrenches,
<div> </div>
<div>Does anyone know of a non-sensor based tracker controller that can work with a variety of tracker motors?</div>
<div> </div>
<div>We don't do trackers much but we have a WattSun DuraTrak controller that has never worked well, we've tried all sorts of tweaks. Its a tougher location that a lot because there are high snowy peaks that confuse the tracker I guess.</div>
<div> </div>
<div>It seems like something would be out there that would just use the sun position equation instead of sensors that can be confused.</div>

<div>Thanks for your input<br clear="all" />
