SEM5046 Compact Photovoltaic Meteorological Station

SEM5046 compact meteorological station is an instrument used in photovoltaic power station and new energy monitoring field. The product innovatively integrates various meteorological parameters that need to be monitored in the operation and maintenance management of the photovoltaic power station into one structure, which can simultaneously measure: atmospheric temperature, relative humidity, module temperature, wind speed, wind direction, atmospheric pressure, total solar radiation POA, and total radiation daily cumulative radiation.
