6 FAQs about [Photovoltaic inverter lightning arrester failure]
Do lightning strikes damage electrical components in photovoltaic systems?
NREL 46526. NREL prints on paper that contains recycled content. Abstract—Surges caused by lightning strikes could damage electrical components in photovoltaic (PV) systems. Metal oxide varistors (MOVs) are commonly used to protect PV systems from lightning strikes. This paper proposes a holistic impulse-based MOV lifetime estimation framework.
Are PV systems vulnerable to lightning?
Similar to other power systems [ , , , , ], PV systems are vulnerable to lightning because they are always installed in unsheltered open areas. Recent studies on lightning protection of PV systems have drawn much attentions [ 9 ].
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).
What is lightning induced voltage in a photovoltaic system?
Simulation of surges in a photovoltaic system Lightning induced voltages in DC cables is one of the critical issues in lightning protection of PV systems. This voltage may damage the inverter connected to the DC cable. The induced voltage on the PV panel could damage bypass diodes connected to the panel as well.
What happens if a PV system is not protected against lightning?
Many PV systems may not be properly protected against lightning. Due to this exposure, the PV systems may be liable to suffer a crucial impact in a way that can lead towards severe damage for instances; failure of the electrical and electronic parts in the building or PV installation and disruption of their normal operation.
