Solar inverter secondary lightning protection

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.

Which SPD type should be used for a lightning inverter?

If lightning partial currents are expected, an SPD type I with connected SPD type II should be used. For inverters with one MPP tracker, the strings are combined before the inverter and connected to the SPD(s) at the point of interconnection. For inverters with multiple MPP trackers, an SPD or SPD combination should be planned for each input.

Can a PV system withstand flashes of lightning & overvoltage?

In PV systems, the PV arrays are outdoors, frequently on buildings. Depending on the situation, the inverters are also installed outdoors. For this reason, even at the planning stage of the PV system, you should determine whether measures need to be taken to deal with flashes of lightning and overvoltage.

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.
