Fully compliant with ISO 9060:2018 spectrally flat Class C and IEC 6174-1 Class C specifications, the SMP3 is a compact, light pyranometer that provides reliable and good quality data in a wide range of operational environments.
The SMP3 are robust pyranometers that have been designed to provide high quality measurements with little maintenance needs. The SMP6 is fitted with a maintenance-free internal desiccant that lasts at least 10 years. The SMP3 can be used as an economical solution for efficiency and maintenance monitoring of small commercial PV installations, private solar monitoring, or simple solar studies.
The SMP3 has Modbus® RTU RS-485 serial communication, plus an amplified analog output. The sensitivity is stored inside for standardized outputs and it features improved response time and digital temperature compensation. These units can be integrated into SCADA systems and easily swapped out without the need to alter the SCADA systems.
