Technical Information
This phenomenon does not affect the insulation of the PV modules in any way, so personal safety is of course guaranteed at all times. However, the operating behavior of the inverters
In addition, leak current can also electrify the solar inverter casing, thus threatening physical safety. Standard and detection of leakage current
Leakage 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.
Failure Occurrence and Cause In wet weather, "leakage current faults" are more likely to occur than "PV insulation faults", and leakage current protection equipment is more commonly triggered which will cause the inverter to shut down.
The current sensor is installed on the external line output interface of the inverter, so as to detect the current of the solar inverter output ground electrode. Leakage current control technology
