Sonel PVM-1021 Pro Solar PV Installation Tester

Globally, the most durable handheld PV 1000V Solar Tester

The PVM-1021 is a compact photovoltaic system meter with 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 in ground-mounted PV systems. Large memory significantly shortens preparation of documents after the measurement.

PVM-1021 Features

• It can be used for category 1 measurements according to EN 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 EN 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 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: R
ISO+ 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.

IRM-1 Solar Irradiance and Temperature Meter

• Solar radiation intensity (irradiance) in W/m2 or BTU/ft2h.
• 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.

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 master meter – even over long distances.
Measurement data from the PVM-1021 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.
