Mini-grid And Submetering Project LoraWAN Din-rail Single Phase Electricity Meter For Nigeria Dares Program

The LoRaWAN Din-Rail Single-Phase Electricity Meter is a compact and efficient solution, perfect for mini-grid applications where space is limited. Each meter is equipped with an integrated LoRaWAN wireless module, enabling seamless data transmission to a gateway over long distances. The gateway then forwards this data to a server via GPRS/4G or Ethernet. With a communication range of up to 5 kilometers in open areas, a single gateway can support up to 20,000 meters, making the system highly scalable for large networks.

The meter features a clear LCD display that provides real-time monitoring of energy consumption and other critical metrics, simplifying energy management and ensuring efficient operation for system operators.

Designed with safety and reliability in mind, the meter operates within a voltage range of 70% to 120% of the nominal voltage (Un), ensuring stable performance even under fluctuating conditions.

To enhance connectivity, the meter includes an infrared optical data port, which allows for smooth integration with other smart devices. This feature supports the creation of a smart grid, enabling better automation and energy optimization.

Additionally, the meter is equipped with a built-in lithium-ion battery, providing reliable energy storage to maintain power supply to connected devices and appliances during power outages.

In summary, the LoRaWAN Din-Rail Single-Phase Electricity Meter is an advanced, flexible, and efficient solution for managing energy usage in smart grid environments. It offers robust communication, energy optimization, and seamless integration with other smart technologies, making it a versatile choice for modern energy management.
