Thiết bị kiểm tra tấm pin năng lượng mặt trời 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 insolation and temperature measuring instrument BENNING SUN 2
- memory of measured values for 999 PV string tests
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.
With radio connection to the optional BENNING SUN 2 (item no. 050420), the existing radiation conditions (W/m²) as well as the PV module temperature and ambient temperature (°C) are automatically stored for each test procedure.
Features
- automatic test procedure (+/-, Vo/c, Is/c, W/m2, °C) with reverse polarity protection
- powerful short-circuit current measurement, reserve is up to 4 x larger than for conventional PV testers with 10 A limitation
- 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
- integrated memory of measured values for 999 PV string/ PV fields
- real-time clock with date/time stamp per measurement
- USB interface and download software (CSV format)
- large LC display with illumination
- optimum transport and storage protection (IP 64)
