Case
Product Case
A large-scale renewable energy developer managing solar and wind farms across remote regions struggled with fragmented energy data collection and inconsistent connectivity. Its network of distributed sensors, meters, and IoT devices relied on disjointed communication methods, leading to delayed data transmission, difficulty integrating diverse equipment types, and challenges in real-time monitoring of energy production. Additionally, the need for customized data collection logic to adapt to varying site conditions further complicated operations.
The TG-225 Industrial Gateway stands out primarily for its exceptional connectivity capabilities. Supporting 4G/5G and multi-generational cellular networks, it guarantees stable, high-bandwidth data transmission even in the most remote locations, effectively eliminating any potential data transmission gaps. This ensures that regardless of geographical constraints, users can rely on seamless data flow for critical operations and monitoring.
With the TG-225 in place, the developer now has centralized, real-time access to energy production data across all facilities. The gateway’s reliable connectivity and flexible integration have streamlined monitoring workflows, enabling proactive maintenance and data-driven decisions to optimize renewable energy output. Its industrial-grade safety protections and adaptability to diverse IoT scenarios have made it an essential component of the company’s remote energy management infrastructure.
