Leakage current, also referred to as matrix residual current, arises from parasitic capacitance between the photovoltaic (PV) system and the ground. This phenomenon occurs when the PV system lacks a transformer, forming a low-impedance loop with the power grid. The additional diodes/switches are incorporated in the system to obstruct the leakage current by di connecting the PV array from the grid side r. . 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. As the components age the phenomenon is increasing. You'll learn what causes this fault, how it impacts your system, and the steps you can take to resolve it effectively.
