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 KT-256F thermal imager.

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!
  • KT-256F | Infrared diagnostics.

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

Measured parameters

  • The open circuit voltage of the PV panel or a chain of panels, up to 1000 V 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.
