    Comprehensive measurements of photovoltaic installations

    A set of measuring instruments with accessories. The set includes:

    • Sonel PVM-1020 photovoltaic meter,
    • Sonel IRM-1 solar radiation and temperature meter,
    • Sonel MRU-10 earth resistance meter.

    Capabilities

    • PVM-1020 | It can be used for category 1 measurements according to IEC 62446-1.
    • PVM-1020 | It converts measured parameters into STC conditions according to IEC 60891 by cooperation with the IRM-1 solar radiation and temperature meter.
    • IRM-1 | Measurement of solar radiation and temperature.
    • IRM-1 | The LoRa interface for communication with a master meter – offers a larger range than the Bluetooth technology!
    • MRU-10 | Earthing resistance measurements of photovoltaic installations using the 3-pole method.

    PVM-1020

    Photovoltaic meter

    Features

    • It can be used for category 1 measurements according to IEC 62446-1.
    • AUTO mode for performing a sequence of measurements after one press of the START button.
    • It converts measured parameters into STC conditions according to IEC 60891 by cooperation with the IRM-1 solar radiation and temperature meter.
    • reSYNC function – automatic completion of results with environmental parameters and their conversion to STC conditions after restoring connection with IRM-1.
    • The built-in LoRa radio interface ensures cooperation with the IRM-1 meter over long distances.
