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).

How do I protect my solar power system from lightning?

In this article, you will learn how to protect your solar power system from lightning. Drawing from decades of installer experience, we’ll explore the most cost-effective techniques generally accepted by power system installers. Grounding is the most fundamental technique for protection against lightning damage.

What is internal lightning protection?

The internal lightning protection provides equipotential bonding between metal installations and cables within the system. Metal and conductive system parts, e.g. water pipes, are connected directly with each other for this purpose.

What is a lightning protection system?

Lightning protection systems are intended to prevent damage to buildings from lightning strikes. We distinguish here between internal and external lightning protection. The external lightning protection serves to collect the lightning and conduct it into the ground.

What is external lightning protection?

The external lightning protection serves to collect the lightning and conduct it into the ground. In this way, buildings and systems to be protected are saved from the effects of a direct lightning strike. The external lightning protection consists of air-termination systems, conductors, and the associated grounding arrangement.

Can lightning protection be combined with SMA inverters?

Also, special features of combining overvoltage protection devices with SMA inverters are described. The document covers lightning protection in as far as it influences overvoltage protection. Lightning protection systems are intended to prevent damage to buildings from lightning strikes.
