Lightning & Surge
Protection |
|

|
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.

Citel Surge
Protection Products
Citel PV surge protectors are DIN mount and are ideal for placement inside
combiner boxes.
|
DS210DC Off-Grid Surge Arrestor
The Citel DS210DC series is designed to protect 12V, 24V, 48V and 150V DC
power lines for an off-grid PV system. The surge protectors protect the
charge controller and other system electronics. DS210DC automatically reset
after each lightning surge or electrical transient.
These surge arrestors clamp at much lower voltage than Delta surge arrestors
at left so they offer much better protection for charge controllers and
inverters in low-voltage DC systems. |
|
|
DS50PV Grid-Tie Surge Arrestor
The DS50PV is designed to protect the solar panel array at the solar PV
array combiner box for a utility-interactive PV system. The DS50PV is
designed to withstand 40kA (8/20us) induced transient surges and is designed
with replaceable modules.
Use the DS50PV-500 for systems with inverters that have an upper limit of
500 volts. Use the DS50PV-800 for inverters that allow arrays over 500 VDC.
For use with grounded arrays.
|
|
|
DS60PV Grid-Tie Surge Arrestor
DS60PV are Type 1 heavy duty surge protectors, recommended when a direct
lightning strike is possible on the installation. They are available in 500-
and 1000-VDC operating voltages. The use of Type 1 surge protector is
recommended at both ends of the DC power supply line (solar panel side and
inverter/converter side).
The DS60PV is made with a monobloc enclosure and mounts on DIN rail.
