Surge Protection for PV System
PV systems are exposed to both direct and indirect lightning events. The impact of lightning events increases with PV system size. Poorly protected PV systems will suffer repeated and significant damages and thus result in substantial repair and replacement costs, system downtime and loss of revenue. Properly installed surge protective devices (SPDs) will minimize the potential impact of lightning events.
Sensitive electrical equipment of PV system like AC/DC inverter, monitoring devices and PV array must be protected by surge protective devices (SPD).
