Does the photovoltaic inverter have overvoltage protection

Merged North American and Rest-of-World versions Added SPD options for commercial inverters . A surge protection device alone cannot protect electronic equipment from a direct lightning strike. External protection is required to attract the. . 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,. .
