6 FAQs about [Photovoltaic inverter AC DC lightning arrester]

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).

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.

Does a PV inverter need a strike?

However, the inverter is typically the most expensive component within a PV system, which is why it is essential to properly select and install the correct SPD on both the ac and dc lines. The closer the strike is to the inverter, the more damaged the inverter will be.

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).

How do lightning discharges affect a PV system?

Lightning discharges cause field-based and conducted electrical interference. This effect increases in relation with increasing cable lengths or conductor loops. Surges do not only damage the PV modules, inverters and their monitor-ing electronics, but also devices in the building installation.
