Photovoltaic Systems Testers

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.
