Current situation in the market

The technology of photovoltaic modules and the structure of PV strings has changed significantly in recent years. In addition to the higher performance and efficiency of the panels, cell technology and module architecture have also changed. High-performance PV modules of the latest module technology are largely based on the N-type topology. These have the desired high efficiencies (>20 %), but have high intrinsic capacities. These intrinsic capacitances are not specified by module manufacturers. The transient short-circuit currents (_{Isc_cap}) occurring in the short-circuit test can exceed the short-circuit current specified in the PV module data sheet many times over and cannot be measured with normal ammeters / current clamps due to the short discharge time.

Due to the circuit design, the BENNING PV 2 limits the peak current. However, the connected power / energy (due to the module capacitance, the transient short-circuit current and the string voltage) significantly exceeds the characteristic values of the tester.

Measuring channels:

C1 = String voltage (500V)
C2 = Short-circuit current reference (max. 135A)
C3 = Short-circuit current (max. 139.7A)
F1 = Function C1*C3 for power calculation (max. 61kW)

The BENNING PV 2 from model year 2024 are equipped with a pre-test to determine the capacitive energy of the string for self-protection against excessive current peaks. If the BENNING PV 2 detects a string with excessive intrinsic capacitance, the measurement is aborted with the error message HiSc or HiCu (>15.00 A).

PC Software BENNING SOLAR Manager

We also recommend using the optional PC software BENNING SOLAR Manager. The PC software used with the BENNING PV 2 allows the creation of test reports as well as documentation in compliance with the standards EN 62446 and EN 61829. The measured I-V characteristics and power characteristics of the BENNING PV 2 can be converted to standard test conditions (STC) and can be compared with the manufacturer’s nominal specifications via an integrated PV module database.
