TrackerMaster is the control system for large PV plants using 1-axis trackers. The system is made of three basic devices:

  • Tracker control unit (TCU)
  • Sun position server (SPS)
  • Meteo station (MET)

Several SPS and meteo stations can be used for redundancy. All devices communicate within a single mesh wireless network that support up to 200 trackers.
Every device works like a router and there are no central gateways, which allows for a reliable and fast communication between devices over long distances.
