Causes of leakage current in photovoltaic inverters

Undesirable tripping of residual current protection system;Deterioration of electromagnetic compatibility (EMC);Decreasing of PV modules lifetime;Harmonic distortion of the current injected into the grid;An electric shock for persons touching the PV module. [pdf]

FAQS about Causes of leakage current in photovoltaic inverters

Why does the photovoltaic system generate leakage current?

Leakage current of the photovoltaic system, which is also known as the square matrix residual current, is essentially a kind of common mode current. The cause is that there is parasitic capacitance between the photovoltaic system and the earth.

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.

Does leakage current affect solar inverter?

In addition, leak current can also electrify the solar inverter casing, thus threatening physical safety. Standard and detection of leakage current

What is the leakage current of a transformerless PV inverter?

In H6 topology and paralleled-buck topology, the leakage current is 29.4 and 35.4 mA. There are almost no high-frequency voltages in vPE. Several single-phase transformerless PV inverter topologies are analysed about the efficiency and the leakage current.

How do leakage currents affect PV module efficiency?

This will induce leakage currents flowing through the module package potentially leading to significant PV module efficiency loss. In standard p-type c-Si PV modules, leakage currents can flow from the module frame to the solar cells along several different pathways (Fig. 2), which are depicted as follows:12,13,44,48–50

What happens if a PV system leaks?

This can flow through a human body and pose serious risks if exceeding a specific value. Also, the leakage current can cause efficiency reduction, harmonic injection, and increased total harmonic distortion (THD) in the grid current [ 8 ]. Figure 1 shows an overview of the PV system, including the inverter, output inductor and grid.
