Proper surge protection is essential. To protect solar inverters from lightning damage, install appropriate Surge Protection Devices (SPDs) 1 on both AC and DC sides of the system. Select SPDs with voltage ratings matching your system's maximum voltage, and ensure they're properly grounded. This includes installing appropriate surge protectors at PV arrays, combiner boxes, inverters, and grid connection points with. Lightning protection systems are essential for solar farms to safeguard against the risks posed by direct and indirect lightning strikes, which can cause damage to solar panels, inverters, and other critical components. If GFDI is not included in the dc-to-dc converter, the installation manual must provide a warning statement that indicates GFDI is not included. The GFDI must provide. For solar street lights, protect both power paths and sensitive electronics: controller, driver, sensors, radios, and (if present) AC inverter interfaces.
