Sonel PVM-1020 Photovoltaic Meter

The Sonel PVM-1020 photovoltaic system meter has an extensive range of measurement capabilities. Function selection is intuitive and handled via a rotary switch, while additional settings are managed using arranged, backlit buttons on the housing. The illuminated graphic display ensures excellent visibility, even in shaded areas.

The PVM-1020 has IP65-rated housing that protects it against dust and water ingress. The device supports wireless data transfer via Bluetooth and is compatible with Sonel Reader & Reports PLUS software.

The PVM-1020 integrates with the IRM-1 environmental meter. When the IRM-1 temporarily loses connection with the master PVM-1020 due to distance, the system maintains continuity. Once reconnected, any missing environmental data is automatically synced from the IRM-1’s temporary memory and adjusted to standard test conditions (STC).

Please note the IRM-1 is not included.

Key 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
