6 FAQs about [Photovoltaic solar panel leakage protector]

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.

Does a solar inverter detect leakage current?

Standard and detection of leakage current According to the 7.10.2 regulation of NB32004-2013 standard, in any case where the solar inverter is connected to the AC grid and the AC breaker is turned off, the inverter should provide leak current detection.

What type of current sensor is required for photovoltaic leakage?

And it has an extremely high precision requirement, a special current sensor is required. The photovoltaic standard stipulates that for the detection of photovoltaic leakage current, Type B, that is, a current sensor capable of measuring both AC and DC leakage currents, must be used.

Why do photovoltaic panels need an external lightning protection system?

The installation of an external lightning protection system has the mission of avoiding direct impacts on the structure, and therefore in this case on the photovoltaic panels installed on its roof.

What happens if a photovoltaic system is connected to a grid?

Hazard of leakage current If the leakage current in the photovoltaic system, including the DC part and the AC part, is connected to the grid, it can cause problems such as grid-connected current distortion and electromagnetic interference, so as to affect the operation of the equipment in the grid.
