The MidNite Solar 300V Surge Protector Device (MNSPD) is a Type 1 device per UL1449 rev3. Protection for Classic and other charge controllers, off grid PV combiners and 120/240 VAC circuits.

One of Midnites newest and most anticipated products, the MNSPD's - Midnite Surge Protection Device - are now available!

Protection is achieved by reducing the clamping voltage to a safe level that your system can sustain without damaging any electronics in the system. The MNSPD is designed to clamp a 115,000 amp surge! Blue LED's provide visual indication of operation from a distance. For more information, see the installation manual below.


  • Type 1 device, designed for indoor and outdoor applications.
  • Engineered for both AC and DC electric systems
  • Provides protection to service panels, load centers or where the SPD is directly connected to the electronic device requiring protection.
  • Offered in three different voltages to maximize the required protection level. MidNite PN: MNSPD-300-DC

    NOTE: The DC SPD will work well on all DC circuits up to 300 volts as well as any 120/240 VAC circuits. The difference between the AC and DC SPD is the way the LED's are powered. The protection side of things are identical.
