Thermopile Albedometer The SEVEN Thermopile Albedometer is a product of the SEVEN meteorological sensor series, which consists of professional and intelligent measurement sensors with digital interfaces for environmental and photovoltaic system. The SEVEN Thermopile Albedometer is equipped with two thermopile pyranometers; one upward-facing and one downward-facing. This allows it to simultaneously measure both global solar irradiance and reflected irradiance from the surface, enabling precise albedo calculations. It delivers outstanding performance particularly in PV plant applications, where monitoring panel and ground reflections and analyzing energy losses are critical. The SEVEN pyranometers (3S-TP-MB-A) used in the Thermopile Albedometer are designed to meet the “ISO 9060:2018, Fast Response, Spectrally Flat, Class A” and “IEC 61724-1:2021 Class A” standards. State-of-the-art thermopile detector and diffuser technology delivers low zero offset behavior, high stability, and reliable long-term performance, maximizing measurement accuracy. This advanced instrument is ideal for meeting the highest standards in solar energy system performance monitoring. Measured global and reflected irradiance data are transmitted to data loggers and other receiving units via the RS485 serial interface using the Modbus RTU protocol, enabling fast and seamless SCADA/AWS integration. • ISO 9060:2018 Class A (Secondary Standard) • Multi - Parameter Monitoring • Fast & Simple Installation • Free Software Updates • SunSpec Compliant • SEVEN Remote Setup Service • SEVEN Customer Support • Advanced Detection • Fast Response • Spectrally Flat • Low Zero Offset Behavior • Exceptional Stability Pinarcay OSB Mahallesi 11.
