 Product Description

Midnite Solar Surge Protector - MNSPD300-ac

Midnite Solar, Surge Protector Device, 3-wire, 385VDC, for 120/240VAC DC systems, MNSPD300-DC

The MidNite Solar 300V Surge Protector Device (MNSPD) is a Type 2 device per UL1449 rev3. It is designed for both AC and DC systems and provides protection to service panels, load centers, Classic, other charge controllers, off grid PV combiners, 120/240 VAC circuits or where the SPD is directly connected to the electronic device requiring protection. Listed by ETL for US & Canada.

The MidNite Solar Surge-Protector Device (MNSPD) is a Type 2 device 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 four versions 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 the electronics. The MidNite Solar SPD voltage rating should be chosen according to the nominal voltage of the system. Response time is 8/20 µs to clamp 128,000 A. There are two LEDs in each unit that will indicate when the unit is functioning correctly and there is voltage to it.

Install the MNSPD-115 for surge protection on wires coming from a 12, 24, or 48 VDC PV array, DC wind generator or DC hydroelectric turbine. The MNSPD-300-DC unit works well for systems rated at 150 VDC and larger systems with sources up to 300 VDC. The MNSPD-300-AC can be used on120/240 VAC split-phase or two legs each on 208 VAC circuits. The MNSPD-600 is designed for high-voltage grid-tie PV arrays, or two legs each on 480 VAC circuits. Lightning protection can be installed in a combiner box, DC or AC load center or grid-tie inverter. These devices 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, to pumps, or to outbuildings. These surge arrestors mount in a ½" knockout and are covered by a five-year material and workmanship warranty.
