Tester for Photovoltaic Systems BENNING PV 3



  • open-circuit voltage at the PV module, PV string and PV field with up to 1500 V DC
  • powerful short-circuit current measurement of PV strings connected in parallel up to 40 A
  • wireless connection to measuring instrument BENNING SUN 2 – for insolation (W/m2), PV module temperature and ambient temperature (°C) measurements
  • memory of measured values for 999 PV string tests
  • polarity test of the PV generator/ PV cabling
  • automatic test procedure (+/-, Vo/c, Is/c, W/m2, °C) with reverse polarity protection
  • reduced testing times and effort for disassembly, as the individual PV strings no longer have to be separated and tested one after the other
  • reduces the risk of failure due to overload during testing of PV strings of unknown power
  • USB interface and download software (CSV format)
  • large LC display with illumination
  • optimum transport and storage protection (IP 64)


Within the framework of commissioning tests and periodic inspection of grid-connected photovoltaic systems in compliance with DIN EN 62446 (VDE 0126-23), polarity tests as well as open-circuit voltage and short-circuit current measurements of PV strings connected in parallel can be carried out, stored and documented safely and efficiently up to 1500 V/40 A.
