Sonel MPI-540-PV-IRM1 Solar Multifunction Tester with Irradiance Meter

What is the Sonel MPI-540-PV-IRM1?

The Sonel MPI-540-PV + IRM-1 is a complete multifunction solar PV test kit designed for UK electricians working on domestic and commercial installations. It combines the MPI-540-PV electrical installation tester with the IRM-1 irradiance and temperature meter, enabling full AC and DC testing in line with EN 62446 standards. This kit supports performance analysis, fault finding and compliance reporting for photovoltaic systems.

 

How does the MPI-540-PV-IRM1 support solar professionals?

The MPI-540-PV automatically recalculates results to STC conditions, helping verify inverter efficiency and system performance.
