The MidNite Solar Surge Protector (MNSPD) is a Type 2 device. It is designed for both AC and DC systems and provides protection to service panels, load centers or where the SPD is directly connected to the electronic device requiring protection. Maximum protection will only be achieved if the SPD is properly installed. The MidNite Solar SPD is offered in three different voltages to maximize the required protection level. Protection is achieved by reducing the clamping voltage to a safe voltage that your system can sustain without damaging any electronics in the system. The MidNite Solar SPD voltage rating should be chosen according to the nominal voltage of the system. Response time is 8/20µs to clamp 128,000 amps. There are two LED's in each unit that will indicate when the unit is functioning correctly and there is voltage to it.

Install the 150V DC version for surge protection on wires coming from a 12, 24, or 48v PV array, DC wind generator or DC hydroelectric turbine, the 300VDC unit for DC sources up to 300v, and the 600VDC unit for high-voltage grid-tie PV arrays. Lightning protection can be installed in a combiner box, DC load center or grid-tie inverter. They can be used on your AC load center to protect your equipment from surges from the utility lines and on AC wiring running outside of the building, to generators, pumps or outbuildings. Mounts easily in a 1/2" knockout. Material and workmanship warranty for 5 years.
