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 | 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 | 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.
