Hey RossW.....you gonna leave me hanging about that tracker circuit or ya gonna share something with us.....I need to get a circuit put together....want me to be another guinea piglet for your prototype? Okay then, I will....seriously....
OK, OK, I'll draw up what I have a little more clearly and try to get it "in print" for you guys
I'm gonna be a skinny old man after running outside 3-4 time a day to move that switch for the panels.....LOL...
A simple suggestion then. Get a length of ordinary figure-8 wire. (speaker wire, bell wire, whatever) and connect that to your actuator.
Run it inside. Grab a double-pole double-throw toggle switch *with centre off*
Connect the switch as a "reversing" switch (NO of one side to NC of opposite side, for both sides to make a "crossover").
Then, from inside you can swing the array one way or the other (I mount the switch horizontally and mark it west-off-east).
Just move the panel and peak the current meter. Saves the legs
You can just see my switch here on the right hand side - the 5A meter shows me the actuator current (all actuators are in parallel)
