The BENNING PV 125 is a powerful photovoltaic installation tester for commissioning and periodic testing of grid-connected PV systems up to 1500 V. It enables standard-compliant testing in accordance with DIN EN 62446-1 (VDE 0126-23-1) and DIN EN 62446-2 (VDE 0126-23-2) (test method 1) and combines high measurement performance with a fast, practical workflow.
Thanks to AUTO test sequences and an intuitive 3.5" color display, tests can be carried out in just a few seconds - ideal for efficient installation and service work. Additional manual measurements are available for diagnostics and troubleshooting. The internal memory organizes up to 1000 automatic measurements structured by object, inverter and string.
The PV 125 can be conveniently integrated into measurement and documentation processes via Bluetooth and LoRa (Long Range), including OTA firmware updates and data transfer with common operating systems. In combination with optional accessories (e.g. BENNING CM 3-PV and BENNING SUN 3), operating current/power measurements as well as irradiation and temperature values can also be integrated. The device is compatible with the BENNING Test Equipment Cloud (BTEC) for documentation purposes.
