Why Have Surge Protection
Photovoltaic, wind and hydroelectric systems
usually have long runs of exposed wire that can pick up surges from
lightning, even if the lightning strike is not nearby. These power
surges can damage sensitive electronic components in meters, charge
controls and inverters. Surges can also damage telephone, audio and
video equipment connected to the power system. It is a good idea to
install surge protection on all incoming wires in the system,
including incoming PV, wind or hydroelectric power lines, AC generator
lines, telephone and antenna leads. Proper grounding is absolutely
necessary for lightning protection to be effective. In the event of a
direct strike, damage may occur, even with surge protectors installed. |

Delta Lightning Arrestors
The Delta Lightning Arrestors have a max current rating of 60,000 amps and
2,000 joules per line. Response time is 25ns to clamp 50,000 amps. Mounts
easily in a 1/2" knockout.
Install the DC version for surge protection on wires coming from a PV
array, DC wind generator or DC hydroelectric turbine. Use the 600 VDC unit
for high-voltage grid-tie PV arrays. Lightening protection can be installed
in a combiner box, DC load center or intertie inverter.
The AC versions can be mounted in your AC load-center to protect 120/240 VAC equipment and on AC wiring running outside of the building, to
generators, pumps or outbuildings. All units are waterproof.

PolyPhaser DC Lightning Protectors
PolyPhaser Lightning Protectors set the standard for the lightning
protection industry. They are the product of choice in the telecom industry.
Designed to protect PWM switching and relay type charge controls, these
units can handle the high voltage of open circuit arrays and will not cause
power robbing voltage drop.
Models are available for 12 and 24 volt negative
ground systems and 48 volt negative and positive ground systems. Maximum
continuous current 50 amps. |

Lay-in Lugs for Module Grounding
These tin plated copper lugs have stainless steel set screws and come with
stainless steel thread-forming screws and lock washers, to meet NEC
requirements for connecting a continuous ground wire to all modules in an
array and having the ability to remove a module without breaking grounding
continuity for the rest of the aray.
Sold in packages of 10 with
thread-forming screws. UL listed.
