Thermal Sensors Digital Class A pyranometer with heating and tilt sensor Introduced in 2017, SR30 is now the market leading Class A pyranometer for PV system performance monitoring. It is employed where the highest measurement accuracy is required. • • • • • the first pyranometer compliant in its standard configuration with the IEC 61724-1 Class A requirements heated for best data availability: RVH TM technology outperforms traditional pyranometer ventilation lowest total cost of ownership: supported by a worldwide calibration organisation calibrated tilt sensor complying with IEC 61724-1 requirements for single–axis tracker monitoring spectrally flat: WMO compliant, also suitable for Plane of Array, diffuse, and albedo measurement compliant with IEC 61724-1 Class A with heating calibrated tilt sensor Figure 1 SR30: the market leading spectrally flat Class A pyranometer with heating and tilt sensor. Figure 2 To reduce total cost of ownership: make use of the worldwide Hukseflux calibration organisation. Introduction Welcome to the next level in solar radiation monitoring! The all-digital heated SR30-M2-D1 offers the highest accuracy and highest data availability: it outperforms pyranometers equipped with traditional ventilation systems. After introduction in 2017, SR30 was rapidly recognised as the ideal instrument for use in PV system performance monitoring, and is increasingly used in meteorological networks as well. SR30 is an ISO 9060 spectrally flat Class A pyranometer. It measures the solar radiation received by a plane surface, in W/m2, from a 180 ° field of view angle. SR30 offers many advantages over competing pyranometers. Copyright by Hukseflux. Version 2411. We reserve the right to change specifications without prior notice Page 1/7.

IEC 61724-1 Class A compliant SR30 complies, without the need for additional accessories, with IEC requirements. It includes heating for dew and frost mitigation. The instrument has 2 heating modes; normal at < 3 W, and medium at < 0.65 W power. Lowest total cost of ownership Customers prefer Hukseflux pyranometers for their unsurpassed measurement accuracy and their lowest total cost of ownership. Total costs are mainly determined by costs of installation, on-site inspections, servicing and calibration: • pyranometers must be calibrated every 2 years. Such recalibration is considered good practice...

Thermal Sensors Instruments just of class A, B or C, and not spectrally flat, only measure accurately under clear sky conditions. Using "spectrally flat" instruments is essential because this ensures that: • you can measure accurately not only horizontally under clear sky conditions, but also general GHI, POA, albedo and net radiation you comply with WMO requirements you can use the normal standardised ISO and WMO calibration procedures you can also separately measure the diffuse component only (creating a diffusometer) with a shadow ring or shading ball, using the same instrument model you can...

SR30-M2-D1 specifications Remote sensor diagnostics Besides solar irradiance, SR30 outputs sensor diagnostics, including: • instrument temperature • tilt angle • internal ventilator speed (RPM) • internal humidity • heater current Remote diagnostics reduces the need for (un)scheduled field inspections. Liabilities covered: test certificates As required by ISO 9060 for Class A classification, each SR30 is supplied with calibration and test results: • directional response • temperature response • tilt sensor response (0 to 90 °) Calibration uncertainty Measurand Tilt measurement uncertainty ± 1...

Thermal Sensors Operation in 3 power modes Heater and ventilation may be remotely switched on and off. The instrument has 2 heating modes; normal at < 3 W, and medium at < 0.65 W power. Operation without heating is also possible, in the low power mode at < 0.1 W. With decreasing power, the mitigation of dew and frost will become weaker. However, overall performance in all 3 modes will comply with the ISO 9060 Class A classification.
