IRM-1
The Sonel IRM-1 measures solar irradiance with ambient and panel surface temperatures. It can store up to 5,000 readings using internal memory, and the IP65-rated housing protects it from dust and water ingress.
The IRM-1 has a USB port for direct connection to a computer and a built-in LoRa (Long-Range) wireless interface for communicating with compatible Sonel master meters.
