6 FAQs about [Solar power generation with leakage protection]

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.

How to reduce leakage current in a grid-connected photovoltaic system?

Grid-connected photovoltaic system Many topologies have been proposed in the literature to reduce leakage current. The most prominent topologies are the full-bridge structure with bipolar switching method, H5 structure [ 9 ], H6 [ 10, 11 ], and HERIC [ 12] etc.

How can a photovoltaic inverter reduce leakage current?
