SMA module kit for DC overvoltage protection type I and II. DC surge protection protects electrical devices against voltage surges such as lightning. Overvoltage protection ensures potential equalization which neutralizes voltage differences. Thanks to the neutralization of the voltage, connected inverters and solar panels within a system remain undamaged.

Type I overvoltage protection is designed to protect against direct lightning strikes while Type II only protects against indirect lightning strikes. The document 'Brochure SMA Overvoltage Protection | ENG', under Downloads, provides more information on how inverters can be combined with a Surge Protection Device (SPD).
