6 FAQs about [Photovoltaic grid-connected inverter struck by lightning]

How does Lightning affect a PV system?

After studying the influences of lightning strikes on the PV system and modeling methods, it is mandatory to design a protection system for the PV system during lightning. The lightning protection system (LPS) is used to protect the PV system from damage and service interruption.

Can a lightning strike damage a PV inverter?

A direct or indirect lightning strike could induce overvoltages in the DC cables as shown in Fig. 2 (black wires), and cause damages to the PV inverters connected to them. This issue has drawn a lot of attention recently . Fig. 2. A DC cable loop in a PV string (black wires).

Do lightning currents affect grid-connected solar PV farms?

Does lightning damage solar PV systems?

The severity of damage in solar PV systems hit by lightning depends on the characteristics of the lightning current waveshape, amplitude of the lightning current, lightning striking point and installed lightning protection system.

Can a lightning strike damage a solar PV farm?

Therefore, five different points of measurement were used after the lightning strike to identify the travelling waves of the transient voltage and current that can cause damage to the components of the solar PV farm grid-connected system.

Did a lightning strike damage a solar PV array 2?

Although the lightning strike was at the point between the solar PV Array 1 and inverter, the transient voltage and current might have damaged the transformer and inverter PV Array 2 due to generated travelling waves throughout the system.
