Product information

This powerful set was specially developed for professionals in photovoltaics and consists of:

  • PVM-1530 – Multifunctional test instrument for solar systems

  • IRM-1 – Combined irradiance and temperature measuring instrument

  • CMP-1015-PV – Clamp meter for DC current measurement in PV systems


1. Sonel PVM-1530 – High-end measuring instrument for PV systems up to 1500 V

The PVM-1530 impresses as an innovative measuring system for modern solar installations. It covers all measurement tasks in accordance with EN 62446-1 (Category 1 & 2) as well as EN IEC 60891 for STC corrections. The integrated measurement of I-U and P-U characteristic curves as well as insulation resistance makes it the ideal solution for commissioning, maintenance and efficiency monitoring.

Thanks to the large touchscreen with high brightness and simple menu navigation, the instrument can be operated optimally even in direct sunlight. Data storage is structured – ideal for quick evaluation after measurement.

Highlights:

  • Voltage measurement up to 1500 V DC, current up to 40 A DC

  • I-U/P-U curve recording incl. STC conversion

  • Resistance measurement of PE and equipotential bonding conductors

  • Full integration of the IRM-1 via radio connection (LoRa)

  • Bluetooth/WiFi/USB for data transmission

  • reSYNC technology for automatic resynchronization in case of signal loss

  • Robust, weatherproof housing (IP67)


2. Sonel IRM-1 – Capture weather data compactly and precisely

The IRM-1 delivers essential environmental parameters such as solar irradiance, module temperature, ambient temperature, module inclination and orientation. This makes it an indispensable partner for precise STC corrections and supports both live measurement and analysis prior to a PV installation.

A large internal memory with logger function (5000 data records) enables long-term recordings. Communication with the PVM-1530 takes place wirelessly via LoRa – ideal for long distances.

Functions at a glance:

  • Irradiance in W/m² or BTU/ft²·h

  • Temperature measurement of modules & ambient

  • Compass & inclination sensor integrated

  • IP65 housing for reliable outdoor use

  • USB interface & wireless communication (LoRa)


3. Sonel CMP-1015-PV – Clamp meter for demanding DC measurements

The CMP-1015-PV was specially designed for PV applications and allows precise measurement of direct current up to 1500 V. Thanks to the VFD function, the instrument is also suitable for measurements on frequency converters – an advantage in modern hybrid systems.

Special features:

  • Voltage and current measurement in the DC range

  • Compatible with the PVM-1530 for live current measurements

  • Ideal for commissioning and troubleshooting in PV systems


Conclusion

This measuring instrument set is the perfect equipment for solar installers, experts and maintenance personnel who want to evaluate the condition and performance of photovoltaic systems with professional tools – precise, robust and future-proof.
