6 FAQs about [Photovoltaic inverter lightning protection design specifications]

Does a PV inverter have overvoltage protection?

The inverter is manufactured with internal overvoltage protection on the AC and DC (PV) sides. If the PV system is installed on a building with an existing lightning protection system, the PV system must also be properly included in the lightning protection system.

Can a PV system be installed on a building with a lightning protection system?

If the PV system is installed on a building with an existing lightning protection system, the PV system must also be properly included in the lightning protection system. The inverters are classified as having Type III (class D) protection (limited protection).

What is lightning induced voltage in a photovoltaic system?

Simulation of surges in a photovoltaic system Lightning induced voltages in DC cables is one of the critical issues in lightning protection of PV systems. This voltage may damage the inverter connected to the DC cable. The induced voltage on the PV panel could damage bypass diodes connected to the panel as well.

Are PV systems vulnerable to lightning?

Similar to other power systems [ , , , , ], PV systems are vulnerable to lightning because they are always installed in unsheltered open areas. Recent studies on lightning protection of PV systems have drawn much attentions [ 9 ].

How does indirect lightning affect solar PV systems?

Indirect lightning strikes can easily damage the sensitive components within solar PV systems, leading to high repair or replacement costs and decreased system reliability [1]. The overvoltage experienced by the PV system depends on its specific setup and wiring conditions.

How vulnerable are photovoltaic systems to lightning strikes?

Photovoltaic systems are vulnerable to both direct and indirect lightning strikes. Therefore, they must be built with reliable and properly installed surge protection. (References: [1] Lightning Protection Guide, DIN EN Standard 62305-3, 2014. [2])
