The pyranometer is compliant in its standard configuration with Class A requirements of the new IEC 61724-1 standard. SR30 is “Secondary Standard” in the ISO 9060:1990 standard and “Spectrally Flat Class A” in the ISO 9060:2018 revision. It is the ideal instrument for use in PV system performance monitoring and meteorological networks.
Heated for high data availability, featuring new RVH™ technology
High data availability is attained by heating of the outer dome using ventilation between the inner and outer dome. RVH™- Recirculating Ventilation and Heating – technology, developed by Hukseflux, suppresses dew and frost deposition and is as effective as traditional ventilation systems, without the maintenance hassle and large footprint.
The dome of SR30 pyranometer is heated by ventilating the area between the inner and outer dome. RVH™ is much more efficient than traditional ventilation, where most of the heat is carried away with the ventilation air. Recirculating ventilation is as effective in suppressing dew and frost deposition at 2 W as traditional ventilation is at 10 W. RVH™ technology also leads to a reduction of zero offsets.
Compliant with IEC 61724-1:2017 Class A and B
IEC 61724-1: Photovoltaic System Performance Monitoring – Guidelines for Measurement, Data Exchange and Analysis – requires ventilation and heating for Class A monitoring. The SR30 complies with both, without the need for additional accessories.
