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.
