[RE-wrenches] Watsun problem

[Glenn Burt]

Any sign of electronics failure in the controller box?
Recent lightning activity in close proximity?
How about a dead spot in the limit switch, or limit switch inoperable?

Hello,

I am having an issue with a Watsun dual axis tracker. 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. 

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. 

Any thoughts?

Thanks as always,

Jesse
