AC SPD
SUNNOM Solar DC Surge Protection Device (SPD) is a key safety component of photovoltaic power generation system, which is specially used to protect the DC side from instantaneous overvoltage (surge) caused by lightning strike, switch operation or grid fluctuation. It can effectively protect photovoltaic modules, inverters, combiner boxes and other equipment from high voltage shock, ensure stable operation of the system and extend the life of the equipment.
