NOTE: The MNSPD-300-AC and MNSPD-300-DC models are new replacements for the previous model MNSPD-300. They offer the same level of protection but the wiring for the LED lights has changed. Please see this document for an explanation of the changes.

The MidNite Solar surge protection device (SPD) is offered in four different models: MNSPD-115, MNSPD300-AC, MNSPD-300-DC and MNSPD-600.
