4-Wire Lightning Protector $60.00
Solar Living
Here is a simple, effective protection that can be used on any PV, wind, or hydro system up to 300 volts DC. These high-capacity silicon oxide arrestors will absorb multiple strikes until their capacity is reached and they rupture, indicating need for replacement. Three-wire connection, positive, negative, and ground, can be done at any convenient point in the system. The AC unit is identical operation and capacity; only the wire color codes vary. The 4-wire unit is for wind turbines with a 3-phase output (Whisper and Bergey turbines). USA.
