Smart Gateway for Multi-Device Protocol Integration
The Tespro edge gateway did protocol conversion (DLMS/Modbus/MQTT) and it could serve various communication chips such as RS485, 4G, and Wi-Fi. It served as a local data collection and forwarding center.
Case
Product Case
A series of 1,000 TG-325 intelligent edge computing gateways directly ordered by a major Brazilian energy utility firm of Tespro have been implemented in 30+ distributed energy projects in Brazil, Argentina and Chile. These gateways are the heart of the single energy monitoring and management system of the client.
The TG-325 has 2 RS485 interfaces, 1 RS232 port and 4 GPIO channels, which allow connection to solar inverters, smart energy meters, and grid monitoring sensors.
It used in favor of global frequency bands and 2G/3G/4G/5G multi-network redundancy, which guarantees a consistent transfer of data in remote mountainous-coastal locations. It has a wide protocol coverage combining the data streams of a wide variety of energy devices.
When it was implemented the solution became very effective. The client had reported a 99.5-percent data transmission reliability and 35-percent improvement in energy monitoring response time.
The centralized real-time management increased the production of the distributed energy by 12 percent and reduced on-site maintenance expenditure by 30 percent. The TG-325 was deemed as essential to the international energy endeavours of the client.
The protocol customization and on-site deployment services of Tespro offered Latin American technical team whose services were effective in ensuring smooth integration with the existing grid infrastructure.
