Tracker Control Unit (TCU)
Suntrack® TCU (Tracker Control Unit) is the most reliable single-axis solar tracker controller. This device moves the tracker motor to follow the path of the sun and thus optimizes solar energy production. Its use is recommended for all common types of PV modules.
Scale your PV project
- The TCU features integrated 3D Backtracking and advanced functionalities, including Winter Mode, i-Stow®, i-Flood, and Dynamic Limits.
- One million TCU company (50 GW)
Our TCU is designed to minimize the angle of incidence between the incoming sunlight and the photovoltaic panel using a built-in solar-position algorithm that drives a motor with feedback from an integrated 3-axis accelerometer for accurate inclination measurement.
Increased functionality
Highest reliability
- Maximum output with embedded adaptive 3D Backtracking®
- Directly powered from the solar panel array
- Additional configuration flexibility
- Encrypted communications to help in a secure communications network
Our TCU has wide operating temperature ranges and it’s locally operated via a smartphone app with Bluetooth communication.
With one million TCUs installed over more than 4,000+ sites, Suntrack is the most bankable and reliable solution for utility-scale projects worldwide. Our systems are compliant with international certifications (including UL/CSA/IEC) and offer a full warranty policy.
Customizable Adaptive System
-
Self-Powered Plus
SPP
- The TCU achieves the highest availability in the market and reduces CAPEX by eliminating the need for a dedicated charging panel
- Output power 150W/300W
- A dedicated PV module isn’t needed
- SPP allows continuous power availability for the TCU while freeing up space on the tracker surface
- When irradiance is very low, the TCU is still able to obtain the energy
- Negligible consumption (30 W, less than 0.02 % of the tracker production throughout the year)
- Plug & Play capabilities
- Fully configurable
- Encrypted wireless Zigbee mesh communication options
