3 FOCUS PRODUCTS FOR SOLAR Residential 5 to 36kW Mersen is a trusted partner of electrical equipment distributors and played a leadership role in solar power circuit protection long before the boom reached the residential market, i.e. for private homes, small apartment buildings and farm buildings. Commercial and Industrial 36 to 250kW The walls and roofs of buildings - office towers, factories, malls and warehouses - are among the preferred supports for solar power systems. Architects and developers have grasped the importance of this energy revolution, and more of them are recommending green solutions. Utility and Solar Farm Over 250kW In this type of application, the architecture is centered on an automatic monitoring and control system. Mersen caters to this critical market with electrical protection that safely and reliably protects the solar power investment. Mersen Solutions for photovoltaic 3

4 STANDARDIZATION COMPONENTS, SYSTEMS AND INSTALLATIONS Photovoltaic equipement and systems are governed by international general standards. IEC and UL standards provide the rules to apply to implement state-of-the-art PV installations. Besides that international or more local standards relay and complete the general standards. They concern more precise fields such as: complete systems and installations, components incorporated in the systems and connection to the grid. General Standards IEC Edition 1 Installation and safety requirements for photovoltaic (PV) generators Standards, Guidelines, Recommendations PV Installations PV Systems IEC Low Voltage Installations PV Installations.

5 PHOTOVOLTAIC EQUIPMENT PROTECTION BY gpv FUSES 1 - Necessary data required for calculations of photovoltaic protection: M = number of modules in series in a string (a chain) N = number of strings (chains) in parallel For the used module: IRM = maximum reverse current of a module Nota: the module is tested according to the standard at a value equal to: 135% x IRM during 2 hours: the module has to withstand this condition Voc STC = open circuit voltage Isc STC = short circuit current STC = Standard Test Conditions = irradiance W/m 2, Air Mass 1.5, Cell temperature 25 C (Nc-1)xI SC group I SC group 2 - Presence of fuses at the string level: a) One or two strings in parallel: fuses are not necessary b) Three or more strings in parallel: the maximum number of strings in parallel without electrical protection is given according to the following formula: N (1 + IRM / ISC STC) 3 - Location of fuses in the strings: Usually, the usage is to put a fuse on each polarity (positive and negative) of each string in floating circuit configuration, and one otherwise. 4 - Rated voltage required for gpv fuses: The annex BB of the IEC standard gives information to determine the rated voltage of the gpv fuse-link to be selected. This voltage has to take into account the Voc STC of the string at the lowest application temperature. Voc STC of the string = M x Voc STC of one module I SC group I SC group recombiner box or input of the inverter At 25 C the open circuit voltage rises to 1.2 times Voc STC Consequently the fuse-link rated voltage has to be 1.2 Voc STC of the string 1.2 M x Voc STC of one module string Nota: the table 104 of the IEC requires breaking tests carried out at a mean value of recovery voltage fixed at 100 (0->+5) % of the fuse rated voltage. These conditions are the same as those of UL standards UL or UL So, the coefficient 1.2 is applicable with both IEC and UL fuses. 5 - Rated current required for gpv fuses: The annex BB of the IEC standard gives information to determine the rated current of the gpv fuse-link to be selected. The same calculation has to be applied to the gpv fuses at the string level and to the gpv fuses at the recombination level or at the input of the inverter. With an ambient temperature inside the box lower or equal to 45 C, the fuse rating has to be higher than or equal to 1.4 x Isc STC according to IEC As in practice ambient temperature in the boxes can rise up to 65 C or more, a further derating is needed. Nota: NEC recommends 1.56 x Isc STC for ambient temperature lower than 50 C inside the boxes. 6 - Modules protection against reverse currents: 6a) The corrigendum 1 of the IEC specifies that the tests for the verification of the conventional fusing currents are deemed to give satisfactory results for operation at 1.35 In within two hours. The time-current characteristics of Mersen gpv fuses are in concordance with the following gates: non melting current = 1.13 x In fuse and melting current = 1.35 x In fuse and so, Mersen gpv fuses meet the gates requirements of the UL and IEC standards. 6b) On another side, we have seen in paragraph 1 that the modules are tested according to the standard at a value equal to 135% x IRM during two hours 6c) Conclusion for the modules protection: Conclusion: to protect modules against reverse current, we have to check 1.35 x In fuse lower or equal to 1.35 x IRM Certain withstanding of the module Certain melting of the fuse END USER HAS ONLY TO CHECK: In (fuse rating) has to be lower or equal to IRM (maximum reverse current of the modules) 7 - Fuses gpv at the recombination level: We apply the rules seen in paragraphs 4 & 5 for the determination of the rated voltage of the gpv fuses and for the determination of their ratings: the end user has to check that the calculated ratings are such that the overload protection of the cables is ensured.
