Customer ServiceLeakage 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.
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.
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.
So, when you install a solar surge protector on the PV system, it helps the system run smoothly without sudden surges. As a consequence, the system delivers a better and more consistent performance. Sudden power surges lead the PV system components to degrade with time. It gradually reduces the life expectancy of the solar power system.
However, this device saves the solar power’s PV system from only external surges. You can install them for areas where there is a high chance of lightning strikes. The type 2 DC SPD device is installed at the junction box. This device helps protect solar power’s PV system from indirect lightning.
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.
