Thorigné-Fouillard, France and Ho Chi Minh City, Vietnam, May 21, 2021: Kerlink, a specialist in the Internet of Things (IoT) solutions, and Cloud Energy, a Vietnamese IoT startup serving smart verticals, are developing and deploying new solutions to meet demand for IoT services in rural areas around Ho Chi Minh City.
According to a press release, expanding on their earlier collaboration on smart-building and energy-management projects in the city of nearly 9 million people, the two companies recently developed and deployed a fully wireless LoRaWAN network to monitor and manage a 900 kWp solar-power installation on a mushroom farm 80 km from the city. The installation of the wireless solar-power system was chosen by NG Investment Co., Ltd. for its superior advantages: stability of data reading, ability to connect to different inverter brands and the cost savings on investment and maintenance.
The IoT upgrade included Kerlink’s long-range, low-power Wirnet iStation gateways and its Wanesy Management Center to operate and manage the new system, and Cloud Energy’s advanced LoRaWAN-based meter and devices for data management, optimized to meet the rigorous requirements of utility scaling. The system is expected to reduce the owners’ operation and maintenance costs by 30 percent annually compared to the previous system. New installations are expected to shave 30 percent off the cost of a new wired monitoring system.
Wired monitoring systems are expensive to install and challenging and costly to maintain because employees must be sent to the site for regular inspection and repair throughout the year. A successful deployment of a wireless solar-farm management solution can achieve faster return on investment compared to wired solutions using classic data loggers and non-real-time remote access.
