Hazard of leakage current If the leakage current in the photovoltaic system, including the DC part and the AC part, is connected to the grid, it can cause problems such as grid-connected current distortion and electromagnetic interference, so as to affect the operation of the equipment in the grid.
Typically, the leakage current for this mounting method differs between 75 and 120 μA for non rain conditions and up to 200 μA for rain events. Also it can be observed that the magnitude of the leakage current increases because of an increase of the air humidity which is followed by dew on the module.
In addition, leak current can also electrify the solar inverter casing, thus threatening physical safety. Standard and detection of leakage current
