CNKA solar dc spd Purpose


In photovoltaic equipment systems, lightning strikes, inductive or capacitive coupling voltages from upstream power system switching operations can cause surges, potentially damaging photovoltaic modules, inverters, and other equipment. This can have serious consequences for the operation of the photovoltaic system. To address this issue, photovoltaic lightning protection devices have been specially developed for DC power supply lightning protection, with a maximum working voltage of up to 1200V.
