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. Protection for Classic and other charge controllers, off grid PV combiners and 120/240 VAC circuits. 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 is identical. FAQI ordered the MNSPD-300-DC. Why does my unit say MNSPD-300-AC? All units are labeled "MNSPD-300-AC," however, the marking on the box indicates whether the unit is AC or DC. All units are compatible with both AC and DC systems regardless of the box markings, the only difference is how the indicator lights work. Each unit has several lights and a DC unit hooked up to a DC system will power all of the indicator lights and vice versa; an AC unit hooked up to an AC system will power all of the indicator lights. If you hook a DC unit to an AC system, however, only 1 of the indicator lights will work and vice versa, but the unit will still be safe and function properly. Why aren't all my lights on the MNSPD-300 working? When you try and connect the MSNDP-300-AC on a DC circuit or vice versa, only 1 LED will illuminate, however, the MNSPD-300 is still fully functional. In order that all of the lights work, you would need to connect an AC unit on an AC circuit and a DC unit on a DC circuit.

He said they are more likely to cause a fire than protect anything. Any comments?** A: That is absolutely false. There are some cheap Metal Oxide Varistor (MOV) surge suppressors on the market that have the potential to cause fires but all Midnite SPD Surge Protectors have thermal protection and are ETL certified to UL 1449 standards for risk of fire and electrical shock. We've sold thousands of Midnite SPD's over the years and have never had one catch fire. We HIGHLY recommend adding surge suppression to all solar-electric systems to protect your expensive equipment from lightning induced voltage surges.

Select the model that is closest to, but higher than, the voltage of the wires you are protecting. The 115V for low voltage AC and DC lines, the 300-AC or 300-DC for higher voltage DC lines and 120V/240V AC lines, and the 600V for high voltage lines.

One suppressor at each end of each positive/negative wire pair. So you will have 2 suppressors at your combiner box to protect the solar arrays, and one suppressor at the input of each charge controller so they are protected. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Protection *by L***O on December 1, 2024* You cant go wrong with having extra protection on your solar system after you invested so much and solar sytems are not cheap this protector is a reasonable price and it also looks cool in your system with its led indicators. ### ⭐⭐⭐⭐⭐ Great product!! *by S***E on May 5, 2025* Great surge protection!!
