6 FAQs about [Photovoltaic inverter lightning test method]

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.

Can Lightning transients be measured with a string inverter?

The proposed modelling procedure has been verified experimentally by comparing with the measurement in the laboratory. Finally, lightning transients in a practical PV system with a string inverter are investigated using the proposed method. Systems with and without SPD installation are performed in the simulation.

Is lightning transient evaluation of a PV system necessary?

Lightning transient evaluation of a PV system has been a necessary task in designing effective LPS. Such evaluation has been addressed experimentally and numerically. Stern and Karner [ 10] investigated the induced voltages of a single panel in the laboratory. An inductive coupling model for PV panels was also proposed to assist the design.

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 ].

How do you test a PV inverter?

Test method: Visually check the type and rating of the surge arrestors toensure that they are capable of absorbing expected surge energy fromlightning at the location of the inverter. At present there are no internationally approved PV inverter standards,either by IEC or recommended by PV GAP.

Is lightning protection necessary for PV systems?

Consequently, effective lightning protection is indispensable for PV systems. Lightning transient evaluation of a PV system has been a necessary task in designing effective LPS. Such evaluation has been addressed experimentally and numerically. Stern and Karner [ 10] investigated the induced voltages of a single panel in the laboratory.
