PHOTOVOLTAIC

Photovoltaic, or PV for short, is a technology that converts light directly into electricity. Photovoltaic is also the field of study relating to this technology and there are many research institutes devoted to work on photovoltaic. Due to the growing need for solar energy, the manufacture of solar cells and solar photovoltaic array has expanded dramatically in recent years. Photovoltaic production has been doubling every two years, increasing by an average of 58 percent each year since 2002, making it the world’s fastest-growing energy technology. At the end of 2009, the total global installed capacity was more than 22 GW worldwide. Financial incentives, such as preferential feed-in tariffs for solar-generated electricity and net metering, have supported solar PV installations in many countries including Germany, Japan, and the United States.

gPV

gPV Cylindrical fuse links

PV fuse-links for photovoltaic installations from DF Electric have been developed to offer a compact, safety and economic protection solution in photovoltaic installations where, due to the increase of the power and technologic evolution, no-load voltages above 800V DC are reached. Also meet the requirements for instruments (multimeters) and tarction equipment auxiliary circuits. The range comprises 10×38 & 14×51 fuse-links with rated currents between 1A and 20A. Rated voltage is 600 V DC or 1000V DC (direct current). Provide protection against overloads as well as short-circuits. Made with ceramic tube with high withstand to internal pressure and thermal shock, that allows a high breaking capacity in a reduced physical space. Contacts are made of silver plated copper and melting elements are made of pure silver in order to avoid the aging and thus keep unalterable the electric characteristics. For these fuse-links we recommend the utilization of PMX 1000V fuse holders in single pole version or two-pole version.

gPV NH fuse links

NH gPV 1000V DC fuse-links for photovoltaic installations have been developed to offer a compact, safety and economic protection solution in second level panels of photovoltaic installations. The range comprises NH1(rated currents between 25A and 200A), NH2(rated currents between 200A and 250A) and NH3(rated currents between 200A and 400A) fuse-links. Rated voltage is 1000V DC (direct current). They provide protection against overloads as well as short-circuits (gPV class according to IEC 60269 Standard), with a minimum fusing current of 1,35.In. Made with ceramic body with high withstand to internal pressure and thermal shock. Contacts are made of silver plated copper and melting elements are made of pure silver in order to avoid the aging and thus keep unalterable the electric characteristics. For these fuse-links we recommend the utilization of 1000V NH ST fuse bases. UL Listed (File E355019).
