BENNING PV 125 – Installation Tester for Solar PV Systems up to 1500 V
The BENNING PV 125 is a professional installation tester for commissioning, verification, and periodic inspection of solar PV systems up to 1500 V DC. The instrument is designed for installers, service companies, and technicians working with modern high-voltage solar installations who require fast, precise, and documented testing according to applicable standards.
With the ability to measure open-circuit voltage up to 1500 V DC, short-circuit current up to 25 A, and insulation resistance up to 1500 V, the BENNING PV 125 is a complete tool for troubleshooting, quality assurance, and mandatory documentation of PV installations.
Efficient Testing of Solar PV Systems According to EN 62446
The BENNING PV 125 supports testing procedures according to EN 62446-1 and EN 62446-2, making the instrument suitable for both new installations and periodic inspections of grid-connected solar PV systems.
The automatic test sequences enable complete measurements to be performed in seconds, reducing field time and ensuring consistent measurement results.
The instrument can perform, among other things:
- Measurement of open-circuit voltage (Voc) up to 1500 V DC
- Measurement of short-circuit current (Isc) up to 25 A DC
- Insulation resistance measurement (Riso/Rinsu) up to 999 MΩ
- Protective conductor measurement (Rpe)
- Power measurement on PV strings
- Operating current measurement via BENNING CM 3-PV clamp meter
- Solar irradiance and temperature measurement via BENNING SUN 3
Fast Documentation and Cloud Integration
One of the major advantages of the BENNING PV 125 is its integrated memory for up to 1000 automatic measurements. Measurements can be organized by object, inverter, and string, providing a clear overview for larger installations.
Via Bluetooth, data can be transferred to the BENNING Test Equipment Cloud (BTEC), where documentation, reporting, and administration of measurements become significantly easier. The cloud platform supports Windows, Mac, Android, and iOS and allows for professional documentation of performed test tasks.
Designed for Modern PV Installations
The BENNING PV 125 has been developed with a focus on user-friendliness in the field. The colored 3.5" display, intuitive navigation buttons, and automated test procedures make the instrument easy to use – even under demanding working conditions.
The built-in lithium-ion battery ensures long operating time, while OTA (Over The Air) updates allow for continuous firmware updates of the instrument.
Together with the BENNING SUN 3 and BENNING CM 3-PV, the instrument provides a complete solution for professional testing and documentation of solar PV systems.
