6 FAQs about [Photovoltaic string inverter lightning arrester]

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).

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 mounting system carry a lightning current?

The metal components of the PV mounting system must be connected to the external lightning protection system in such a way that they can carry lightning currents (cop-per conductor with a cross-section of at least 16 mm2 or equivalent).

Can lightning strike a PV site?

It is not necessary for lightning to strike the PV site to damage it; therefore, it is worthwhile to consider all the ways in which lightning can induce surge, including electrostatic and magnetic induction. A surge protection device alone cannot protect electronic equipment from a direct lightning strike.

Do solar power generation systems need a surge arrester?

Solar power generation systems are an integral part of to-day’s electrical systems. They should be equipped with ad-equate lightning current and surge arresters, thus ensuring long-term faultless operation of these sources of electricity. Modular combined lightning current and surge arrester for TN-C systems.

Can a photovoltaic system be tested with lightning and surge protection?

Find answers to frequently asked questions concerning lightning and surge protection for photovoltaic systems. The DEHN test centre is one of the most powerful impulse current laboratories worldwide. Here inverters and mounting systems can be thoroughly tested with a lighting current up to 400 kA.
