This is a high power version of my regular 12V solar tracker. This functions exactly the same as my regular tracker, but will handle twice the current. I have tested these continuously at 10A with no issues at all. If you need even more than 10A from your tracker, you can always purchase my relay module, which will handle up to 30 amperes. This will easily run a high power actuator for your solar tracker. These boards have a user replaceable fuse, and provisions for use of the (optional) remote sensor I also sell. If you are running these near their power limit, you will need to insure proper airflow over the board.

The controller is mounted on the object to be steered with the sensors positioned along the rotational axis. Using most any D.C. motor up to a maximum of 12 VDC @ 10 amps, it can easily cause a solar collector, reflector or array to follow the sun through a single axis. Motors suitable for this system can move quite large loads as long as proper gearing or lead screws are used. The controller uses a differential sensing approach and can drive the motor in either direction. This and all my trackers will track the sun within 5 degrees, and they do not chase clouds.

There is no “reposition for the morning” electronics, but I intentionally used sensors with a wide field of view. In the morning the “east” sensor will trip and the controller will position to point at the morning sun.

This controller will work with 12V motors, solar panels, and batteries. A glass or plastic jar upside down works pretty good. You can also purchase my remote sensors, and mount this board out of the weather as well.

Wiring instructions, installation instructions, and troubleshooting instructions are included. You should use limit switches in your designs.

Note that this controller is tuned for sunlight, I use a 3 watt LED light to test it with.

Solid state, no relays to wear out. Controller has indicator LED’s to let your know when the sensors have tripped.
