Photovoltaic measuring devices Benning PV3 Ref. no.: 050428

• Application:
As part of commissioning and repeat testing of grid-connected photovoltaic systems according to VDE 0126-23 (DIN EN 62446), polarity tests, open-circuit voltages and short-circuit current measurements of parallel-connected PV strings can be carried out, stored and documented safely and efficiently up to 1500 V/40 A.

• General measurement functions:
- Polarity check of the PV generator/PV wiring
- No-load voltage measurement for modern 1500 V DC systems
- Short-circuit current measurement on PV strings up to 40 A DC
- Solar radiation (W/m²) and PV module/ambient temperature (°C) via Benning SUN 2 (order no.: 70 128 24)

• Performance features:
- Automatic test sequence (+/-, Vo/c, ls/c, W/m², °C) with reverse polarity protection
- Powerful short-circuit current measurement, up to 4 x greater reserve than usual PV testers with 10 A limit
- Reduced testing times and disassembly work, as PV strings no longer have to be separated individually and tested one after the other
- Reduces the risk of failure due to overload when testing PV strings of unknown power
- Real-time clock with date and time stamp per measurement
