    Great capabilities in a small casing

    1. PVM-1020 photovoltaic meter

    The Sonel PVM-1020 meter is probably the world's smallest photovoltaic system meter with such a substantial number of measurement functions. The functions are selected with a rotary switch. Additional parameters are set with buttons located on the housing. All buttons and the graphic display are backlit, which greatly facilitates operation in shaded places, e.g. when taking measurements under ground-mounted PV systems. Large memory significantly shortens preparation of documents after the measurement.

    2. IRM-1 solar radiation and temperature meter

    IRM-1, small, but indispensable for testing PV systems. By measuring solar radiation values, as well as panel and ambient temperatures, it provides the necessary data to convert the results into STC conditions. A built-in recorder with a memory of 5000 records enables the instrument to be used as a tool in the PV plant design process, as well as to diagnose panel shading problems.

    PVM-1020 | 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.
    • Built-in Bluetooth module for communication with a computer.
    • Large measurement memory: 100 objects with 40 cells each.
    • Backlit display and buttons.

    PVM-1020 | Measured parameters

    • The open circuit voltage of the PV panel or a chain of panels, up to 1000V DC.
    • RMS voltage of the AC network up to 600 V with frequency measurement.
    • Short circuit current of a PV panel or chain of panels - up to 20 A DC.
    • Insulation resistance of PV panels - measuring voltage of 250, 500 or 1000 V, simultaneous measurement of two values: RISO+ and RISO-.
    • Insulation resistance of AC circuits - measuring voltage 250, 500 or 1000 V.
    • Resistance of protective conductors and equipotential bonding with ± 200 mA current. Low-current resistance measurement, audible and visual signalling.
    • Measurement of PV panels operating current and AC current - all with external clamp.
    • AC/DC power Measurement.
    • Diode test with 200 mA current, automatic polarity detection. Test of blocking diodes with 1000V DC voltage.

    PVM-1020 | Communication and software

    Measurement data from the PVM-1020 can be transferred to a computer via Bluetooth wireless communication. Saving the downloaded data to popular formats and printing ensured by Sonel Reader. In order to generate a report on electric shock protection use the optional software: Sonel Reports PLUS.

    PVM-1020 | Trouble? reSYNC!

    It may happen that in the course of measurements the PVM-1020 moves away from the IRM-1 so far, that communication between them is lost. If the measurements are continued, then after the connection is restored, the results will be automatically supplemented with environmental parameters, which in the meantime were recorded by the IRM-1 in its temporary memory, and converted into STC conditions.

    IRM-1 | Features

    • Measurement of solar radiation and temperature.
    • The LoRa interface for communication with the PVM-1020 meter - offers a larger range than the Bluetooth technology!
    • Automatic data synchronization with the PVM-1020 meter.
    • Built-in compass and inclination sensor.
    • Built-in recorder that can be used to record solar radiation before constructing PV systems, as well as to measure the shading of existing systems.
    • Large measurement memory: 999 cache memory cells and 5000 recorder records available (one-time recording) with the option of overwriting them (continuous recording).

    IRM-1 | Measured parameters

    • Solar radiation intensity (irradiance) in W/m2 or BTU/ft2 h.
    • PV panel temperature in °C or °F.
    • Ambient temperature in °C or °F.
    • Inclination angle of panels
    • Orientation of the panels with the built-in compass.

    IRM-1 | Tightness and durability

    Light meters perform well in harsh environmental conditions. Protection against the ingress of dust and water is provided by the housing rated at IP65. This is especially important for measurements on photovoltaic systems, which are outdoor installations.

    IRM-1 | Communication and software

    Measurement data from the IRM-1 can be transferred to a computer via the USB port. In addition, the device has a built-in wireless LoRa interface (Long Range) for automatic data exchange with the PVM-1020 meter - even over long distances.
