Installation tester for photovoltaic systems and curve tracer BENNING PV 2

• testing in compliance with DIN EN 62446 (VDE 0126-23) and DIN EN 61829 (VDE 0126-24)
• easy – operation by means of keys with AUTO testing procedure
• quick – testing within seconds
• safe – contacting via PV connectors

Before commissioning and for periodic inspections, a photovoltaic system must be tested and documented with regard to its perfectly safe technical condition in compliance with DIN EN 62446 (VDE 0126-23). Moreover, electrical measurements are also useful after cleaning and maintenance work in order to continue to ensure an optimum and low-loss functioning of the PV system.

The test includes continuity testing of earth connections, measurement of the open-circuit voltage and short-circuit current as well as insulating resistance measurement between active conductors (+/-) and earth. The BENNING PV 2 is provided with contact-protected PV measuring leads for direct connection to all PV modules/ strings by means of standardized PV connectors. The automatic testing procedure gives a warning in case of wrong DC polarity and automatically performs all necessary steps for a safe measurement.

On-site measurement of the current-voltage characteristic in compliance with DIN EN 62446 (VDE 0126-23) is a practical method for assessing the performance of photovoltaic systems. The measured I-V characteristics are converted to standard test conditions (STC) using evaluation tools such as the PC software BENNING SOLAR Manager and the Android app BENNING PV Link and can be compared with the nominal PV module data of the manufacturer via an integrated PV module database. Deviations and reduced performance are clearly identified and can be documented correspondingly. Furthermore, the shape of the I-V characteristic provides useful information on the status of a PV system and indicates possible errors.

The BENNING PV 2 allows to carry out the entire test safely, reliably, easily and quickly. The BENNING PV 2 is recommended for daily use by service, cleaning and maintenance teams as well as for solar panel installers and authorized experts for photovoltaics.
