PVM-1020

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

IRM-1

1. Solar radiation intensity (irradiance) in W/m2 or BTU/ft2h.
2. PV panel temperature in °C or °F.
3. Ambient temperature in °C or °F.
4. Inclination angle of panels
5. Orientation of the panels with the built-in compass.
6. PVM-1020: great capabilities in a small casing
7. PVM-1020 meter is probably the world’s smallest photovoltaic system meter with such a substantial number of measurement functions.
8. 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 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.
9. IRM-1: simple and compact 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.
10. Communication and software measurement data from the IRM-1 can be transferred to a computer via the USB port.
11. 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-1020 can be transferred to a computer via Bluetooth wireless communication. Saving the downloaded data to popular formats and printing ensured by Sonel Reader.
12. In order to generate a report on electric shock protection use the optional software: Sonel Reports PLUS. Tightness and durability
13. 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.
