Benning PV 125. PV Installation Tester. Suitable for solar technicians (initial commissioning, periodic testing, troubleshooting), photovoltaic experts, as well as service, cleaning, and maintenance teams. The PV installation tester is designed for compliant installation and periodic testing of grid-connected PV systems up to 1500 V according to VDE 0126-23-1 (DIN EN 62446-1) and VDE 0126-23-2 (DIN EN 62446-2) with testing procedure 1. Powerful - 1500 V (Uo/c), 25 A (Is/c) and RISO measurement. Easy to use for quick and reliable testing. Automatic testing procedures and manual single measurements for effective fault analysis. Internal measurement storage for 1000 automatic measurements organized conveniently by object (10), inverter (10), and string (20). Optimized for modern PV modules with the latest cell technology. Open circuit voltage (Uoc) up to 1500 V DC with automatic display of voltage polarity and warning for reverse polarity. High-capacity PV generators can reduce the maximum measurable open circuit voltage of the device. In case of excessively high short-circuit currents, the device protects itself from overload and refuses the measurement. Short-circuit current (Is/c) up to 25 A DC, insulation resistance (Riso) with test voltage 250 V, 500 V, 1000 V, 1500 V up to 999 MOhm, protective conductor resistance (Rpe) with test current: ± 200 mA DC up to 199 Ohm, operational testing of the PV string through current measurement up to 400 A and DC power measurement up to 600 kW (optional BENNING CM 3-PV and Y-adapter), voltage measurement up to 440 V AC/DC, display of solar irradiation (W/m2) and storage of PV module/environment temperature when coupled with the optional irradiation and temperature measuring device BENNING SUN 3.
