[pdf] 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. In the former case, this causes the inverter to temporarily disconnect from the utility grid, after which. . fects peripheral equipment. Leakage current depends on the inverter's carrier frequency, its input and outp ems through its earth wire. Such the ground leakage current may cause malfunction of the Earth leakage circuit breaker (ELCB), ground-fault relay, fire alarm, and various sensors. The cause is that there is parasitic capacitance between the photovoltaic system and the earth. Suc essentially a kind of common mode current.
