What is a lightning current & surge arrester module?

Space-saving combined lightning current and surge arrester module with actiVsense and LifeCheck technology for protecting two pairs with the same or a different operating voltage of galvanically isolated balanced interfaces. Automatically detects the operating voltage of the useful signal and optimally adapts the voltage protection level to it.

Are surge arrestors UL-listed?

Arrestors are made for various voltages for both AC and DC. Be sure to use the appropriate arrestors for your application. Many system installers routinely use Delta surge arrestors, which are inexpensive and offer some protection where the threat of lightning is moderate, but these units are no longer UL-listed.

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 a lightning arrestor?

Lightning (surge) arrestors are designed to absorb voltage spikes caused by electrical storms (or out-of-spec utility power), and effectively allow the surge to bypass power wiring and your equipment.

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 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.
