In solar photovoltaic systems, lightning strikes and switching operations can induce voltage surges that may damage photovoltaic modules and inverters. This DC surge protection device uses metal oxide varistor technology to instantly redirect high-voltage surge currents to ground, limiting voltage amplitude and protecting equipment insulation. The device automatically resets once the overvoltage condition passes.

Wenzhou Britec Electric Co., LTD. is a professional Chinese SPD manufacturer established in 2003, specializing in low voltage surge protection products with international certifications and global market presence.
