Allowable leakage current of photovoltaic inverter
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. In the former case, this causes the inverter to temporarily disconnect from the utility grid, after which. . Number of strategies have been introduced to mitigate the leakage current in transformer-less converters. The cause is that there is parasitic capacitance between the photovoltaic system and the earth.
