1. 300-AC Surge Protector For all DC circuits up to 300 volts and any 120/240 VAC circuit.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.
2.The Solar Surge Protector is a Class 1 device in accordance with UL1449 rev3. Designed for both AC and DC systems, it provides protection for service panels, load centers, or where the SPD is directly connected to electronic equipment requiring protection. Provides protection for other charge controllers, off-grid PV combiners and 120/240 VAC circuits.
3.The SPD is available in three different voltages to maximize the level of protection required. Protection is achieved by reducing the clamping voltage to a safe voltage that the system can withstand without damaging any electronics in the system.
4.Easy to Install:Some homes have surface mounted electrical panels. These panels are easy to install SPDs on. Simply pop out a 7/8-inch diameter knockout hole and mount the SPD on the door.
