FUSIONSEEKER P6 is a universal heavy duty limit switch with integrated diode designed for protecting all types of single and dual axis solar trackers that use DC motors for moving.

    All solar trackers are basically designed in the way they can rotate for a certain angle only because the sun moves in the way there is absolutely no need for trackers to rotate for more than 300 degrees by azimuth and 90 degrees by elevation. This is general rule for all solar trackers (regular PV solar panel trackers, solar water heating collectors, all types of concentrators,…). The purpose of a limit switch is to stop the solar tracker’s motor (or any other drive system) slightly before tracker’s mechanical limits are reached. This shall be done for both directions what means 2 limit switches are needed per tracking axis. In other words single axis solar tracker needs 2 limit switches and dual axis solar tracker needs 4 limit switches.
