manual / laboratory measurement solutions for solar modules

IV testers are used in a wide range of module laboratories, from R&D facilities to certification and QC labs. A high-performance laboratory tester is needed to meet the diverse requirements of these labs and the different module technologies. Our Moduletest3 can be configured according to the requirements of each task.

Independently certified by TÜV Rheinland and fulfilling the A+A+A+ criteria of the latest IEC60904-9 Ed. 3.0 certification, the Moduletest3 is a piece of equipment your lab should not be without.

Powerful features, such as the fully automatic climate control chambers, which are fully integrated into the system, enable an automated measurement cycle. In combination with the temperature control system and the climate chamber (Therm2), the Moduletest3 complies with all the requirements of IEC61853-1 for STC, NOCT, LIC, HTC and LTC.

The Moduletest3 is an IV measurement system designed for high-end R&D, laboratory, and quality control requirements. The programmable pulsed solar simulator provides highly stable irradiance over long flash durations from a single light source. Used in combination with the halm IV curve tracker and halm's advanced hysteresis feature for measuring high-capacitance modules, this system is designed to meet the needs of current and future solar cell and module technologies.

The versatile system can be equipped with various hardware and software options, such as the electroluminescence imaging solution or a temperature-controlled test chamber.

The Moduletest3 is certified by TÜV Rheinland and fulfils the A+A+A+ criteria according to IEC 60904-9:2020 Ed. 3.0. For further information click here:



halm's Therm-Package-M is an optional bundle for Moduletest3 systems that adds a temperature-controlled chamber to the Moduletest3 IV measurement system. It consists of a thermal chamber for the module being tested and a powerful temperature control unit that allows temperature sweeps from 15 °C to 75 °C. This enables the precise determination of temperature coefficients and complete power rating measurements.


Our EL-package-M adds high-resolution electroluminescence imaging to the halm module IV measurement solutions. Visualizing a wide range of defects provides significant benefits for in-line quality control and research applications. The solution is integrated into the PVControl software and enables seamless data processing and analysis in one system.
