Customer ServiceLeakage current of the photovoltaic system, which is also known as the square matrix residual current, is essentially a kind of common mode current. The cause is that there is parasitic capacitance between the photovoltaic system and the earth.
Standard and detection of leakage current According to the 7.10.2 regulation of NB32004-2013 standard, in any case where the solar inverter is connected to the AC grid and the AC breaker is turned off, the inverter should provide leak current detection.
According to the above analysis, there are mainly three directions that can be adopted to eliminate or minimize leakage currents in single-phase PV connections: Using of common-mode (CM) chokes: this represents an effective solution to mitigate the leakage current in grid-connected systems .
Photovoltaic (PV) modules’ efficiency decreases due to the presence of external electrical potentials due to the phenomenon known as potential induced degradation (PID).
