Connect environmental sensors to the SolarEdge Control and Communication Gateway to monitor site conditions like irradiance, temperature, and wind. Sensors measure direct irradiance, ambient temperature, module temperature, and wind velocity to calculate site performance ratio. Sensors connect to the gateway and include models for irradiance (SE1000-SEN-IRR-S1), ambient temperature (SE1000-SEN-TAMB-S2), module temperature (SE1000-SEN-TMOD-S2), and wind velocity (SE1000-SEN-WIND-S1).
