Our products are the most cost effective and reliable Sun tracking control systems on the market for large solar power plants. Our sun tracking control systems are designed to deliver excellent performance, low maintenance, simple installation, and unattended operation.
TrackerMaster is our solution to control large solar plants using one axis trackers. The system is made of three basic units: Tracker control unit (TCU), Sun position server (SPS) and meteo station (MET). Several SPS and meteo stations can be used for redundancy. All devices communicate within a single wireless mesh network. Every device works like a router, which allows reliable and fast communication between devices over long distances. All devices come in a IP65 enclosure and optically isolated port for configuration and local manual operation. All the software for monitoring and control is web based, accessible with any computer/smartphone.
Tracker control unit
The tracker control unit is responsible to control the tracker movements by means of the integrated inclinometer and the powerful motor control output.
The TCU is available in three versions:
- Grid powered for 24 Vdc 10 A motors.
- Grid powered for 230 V single phase induction motors.
- Self powered for 24 Vdc 6 A motors.
The motor power consumption as well as the battery state of charge are accurately measured to early detect mechanical problems and ageing.
Sun position server
The Sun position server calculates the tracker position for the specific time, date, geographical coordinates, tracker geometry and spacing with 0.0003° accuracy by use of a powerful dual core
240 MHz processor. The SPS also run an internal webserver from which it is possible to monitor and control any tracker of the solar plant. The router of the solar plant can be connected to the Sun position server to allow remote access and data logging.
Our meteo station support two cup anemometers, one wind vane, and a snow height, temperature and humidity sensor.
One or several meteo stations can be used in a solar plant. Each solar tracking control unit receives the wind speed measured by several meteo stations and decide whether to go into stow position based on the wind speed. A priority system allows to configure which anemometers are paired to each solar tracker.
The snow height sensor measure the snow level on the ground by means of a ultrasonic sensor, which also measure air temperature and humidity to compensate for varying sound speed.
We can provide our meteo stations with instruments and accessory parts like:
● Cup anemometer
● Wind vane
● Sun radiation sensor
● Rain sensor
● Snow depth sensor
● Air temperature sensor
● Air humidity sensor
● Custom steel brackets to mount our products on your mast/tracker
