A surge protection device alone cannot protect electronic equipment froma direct lightning strike. External protection is required to attract the lightning and redirect it to the ground, while the SPD absorbs residual energy.

One of the common sources of voltage surge is lightning strikes. 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.

Thunderclouds contain negative charges in their lower sections. These high negative charges can induce high positive charges within nearby.
