6 FAQs about [Photovoltaic panel anti-leakage performance]

How to eliminate leakage current in solar PV array system?

There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.
