SET MPI-540-PV + IRM-1

1. Multi-function meter of electrical and PV system parameters Sonel MPI-540-PV

The multifunctional meter of electrical installation parameters Sonel MPI-540-PV is an advanced tool created in particular for measuring parameters of photovoltaic installations. With the use of one device, it is possible to carry out a whole range of tests on the DC and AC sides in accordance with the guidelines of the EN 62446 standard. In addition, the Sonel MPI-540-PV is also used to carry out all measurements to determine the safety condition of domestic as well as industrial electrical installations. The presented meter is a device with advanced capabilities, dedicated to specialists operating in the installation and electrical industry.

When measuring the parameters of a photovoltaic installation, the meter automatically recalculates the parameters to the STC (Standard Test Conditions) reference conditions. Measurements of voltages, currents and power on the AC and DC side of the inverter will verify its efficiency. After transferring the data stored in the meter's memory to the Sonel Reports PLUS program, it is possible to generate a report of photovoltaic installation parameters.

In order to automate measurements, the Sonel MPI-540-PV meter has been additionally enriched with the function of testing residual current devices in Auto mode. The instrument also has measurement sequences pre-programmed by the manufacturer (so-called autotests), which can be extended with own sequences if necessary. The capabilities and functionality of the meter will be additionally enhanced by a suitably selected additional accessory, e.g. the AutoISO-1000C adapter, which enables the automatic measurement of insulation resistance of 3-, 4- and 5-core cables.

2. Solar radiation and temperature meter Sonel IRM-1

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.

New Packaging Method for Solar Version Meters

As of February 2025, changes have been introduced to the standard equipment of the Sonel MPI-540-PV Solar and Sonel MPI-540-PV Solar Start meters. Both products are now packaged in the dedicated Sonel L-19 backpack.

⚠️ Important Information!
Meter sets with the previous equipment (carrying cases) will still be available for sale until stocks are depleted. Due to differences in packaging, we recommend verifying the standard accessories before purchasing.
