The company

CITEL, a French company founded in 1937, has been manufacturing surge

protection since 1945.

CITEL offers a complete range of surge protection adapted to various

networks including Low Voltage, Telecom, Data, Radiocom.

Since 2005, CITEL has developed a range of surge protection and integrated

enclosure solutions specically for the photovoltaic market.

CITEL's mission is to bring high-performance solutions compliant with the

worlds leading standards in order to insure the best effi ciency and reliability

of your photovoltaic system.

Protection of PV devicesagainsttransient overvoltages

Surge Protectors for PV devices

The photovoltaic installation can be exposed to

overvoltages on different networks :

-AC network: surge protectors are necessary,

sometimes mandatory, for the 230V monophase

network (or 3-phases 230/400V) on which the PV

inverter is connected.

- DC network: surge protectors are necessary,

sometimes mandatory, on the continuous network

in between the modules and the PV inverter.

- Data Network : if the PV inverter is linked to

data lines (transducers, sensors, supervision) surge

protectors are sometimes required.

Most of the solar module manufacturers offer a warranty

of 20 years or more on their products. The cost of such

devices is then calculated on this very long period.

However those installations are very regularly exposed

to lightnings and overvoltages, which can considerably

reduce the desired life expectancy. The use of adaptedsurge protections is then highly recommended.

Several aspects have to be considered to evaluate the risk

"Lightning and Overvoltages" :

The more the solar panel field is expanded, the more

the risk of "lightning" issue is important.

The risk is multiple : direct effect (lightning impact

directly on the modules) and indirect effect (overvoltages

on modules, on the converter/inverter and other

connecions).

When the Photovoltaic devices are located on industrial

sites, the risk of operation overvoltages should be taken in

account as well.

The risks level is directly linked to the density of local

lightning and the exposure of the lines.

The connection of the PV to low voltages should be protected according to the Guide UTE

C15-712 recommandation. Depending on the k ind of network, the presence of lightning rod or on primary

existing surge protectors, CITEL proposes several solutions.

The PV installation can be interconnected to different data networks (transducers, sensors, supervision..). In

that case the use of adapted surge protectors on those networks is recommended.

The DC input of the inverters should be protected according to the recommandations of the UTE C15-

712 Guide. Citel has developped a whole range of products devoted to this application : DS50PV. This one

proposes several solutions :

DS50PV: standard solution using specic varistors, available in common or differential mode.

DS50PV-.../G : version including a branch with gas tube linked to the ground, allowing the total

suppression of leakage current. Protection in common and differential mode.

When the installation is equipped with lightning rods, it is recommanded to use surge protectors specicallydesigned to dissipate a part of the direct impact of the lightning. For those cases, CITEL has developped the

DS60PV series Type 1 surge protectors being able to take up 12.5 kA a pole for a 10/350s wave.
