SUNPOWER TMAC ADVANCED TRACKER CONTROLLER BENEFITS Remote System Control Trackers can be stowed remotely, and system status monitored via the Web Maximized Energy Offers advanced backtracking and precise control for greatest energy collection Predictive Maintenance Self-detects tracker performance deviations and automatically sends alerts with diagnosis before energy output is affected Reliable and Robust Designed and tested to ensure long life even in harsh environments Simplified Installation Avoids the complexity of wired communications The SunPower TMAC Advanced Tracker Controller is the most advanced product of its kind. It is specifically designed to improve solar energy collection while ensuring the high reliability SunPower Trackers are known for. Advanced features (patents pending) include monitoring and operation over the TMAC operator interface and remote stow capabilities via wireless mesh network. Mesh Networking for Tracker Control: Simple, Reliable & Secure. Mesh networking is a type of wireless communications ideally suited for solar trackers. Mesh networks allow hopping of information from node to node along multiple paths, facilitating “self-healing”. This highly reliable configuration is also inherently simple, minimizing network configuration tasks and eliminating the cost and complication of maintaining wired data connections in a field environment. SunPower TMAC communication is encrypted per 128-bit AES standards, the same used to protect most US Government data.

SUNPOWER TMAC ADVANCED TRACKER CONTROLLER TMAC OPERATOR INTERFACE TMAC units connect to a remotely hosted server via Internet connection to the site. With a secure connection to this server, the solar power plant operator can easily access the TMAC operator interface from anywhere, to execute the following: • View tracker status and data, including the last 30 days of history • Set up email alert notification preferences • Issue manual stow command • Configure automated stowing based on measured wind speeds (Requires compatible anemometer installed on-site and networked to TMAC system) • Configure...
