If the continuous residual current exceeds the following limits, the inverter should be disconnected and send a fault signal within 0. 3s: For the inverter with a rated output less than or equal to 30KVA, 300mA. For the inverter with a rated output greater than 30KVA . . 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. In the former case, this causes the inverter to temporarily disconnect from the utility grid, after which. . Current leakage is a fairly common systemic phenomenon in photovoltaic energy installations and it shows up even in new systems, although it is clear that the age of the system plays a role. If this current passes through the human body, it can cause electric shock, injury, or even fatalities, while also potentially leading to. .
