Bussmann series photovoltaic application guide Complete and reliable solar circuit protection Eaton’s Bussmann business has more than 100 years of proven technical innovation to help make your operation more productive while protecting your equipment. Solar Photovoltaic (PV) systems have, over the last 50 years, evolved into a mature, sustainable and adaptive technology. The installations and demand for PV systems increase the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent and overvoltage protection. Eaton’s Bussmann business has worked closely with solar system manufacturers and through coordinated research and development, has produced revolutionary new fuse links which, combined with its combiner box, offer complete protection for PV systems. 2 EATON Bussmann series photovoltaic application guide Table of contents Section Page Eaton’s Bussmann business solar technology solution Introduction IEC 60269-6 gPV standard Photovoltaic module Construction Output String protection Overview How to select fuse links for string protection Worked example Array Protection Overview How to select fuse links for array protection Worked example Solar PV fuse links, fuse holders and blocks offering specifications 10 x 38 mm PVM fuse links 10 x 38 mm PV-A10 fuse links 14 x 51 mm PV fuse links 14 x 65 mm PV fuse links NH Style PV fuse links Flush end PV fuse links XL Style PV fuse links Surge Protection Devices (SPD) PV SPD system overview PV T1 / PV T2 DC SPD PV T2 Standard / high performance AC SPDs overview 4-5 6 6 Data-line SPDs Combiner box Introduction Anatomy of a combiner box Catalogue number system Index Eaton solar protection offering 7 7 8 9 10 11 12 13 14 15 16 - 17 18 19 - 20 21 - 26 27 - 28 29 - 34 35 36 - 37 38 - 40 41 42 43 44 - 45 46 47 48 - 49 EATON Bussmann series photovoltaic application guide 3 Bussmann series technologysolution solution Bussmann solarsolar technology String protection Combiner box 10 x 38, 14 x 51 14 x 65 mm photovoltaic fuse links CHPV Fuse holder In-line fuse holder DC Disco Solar modules Combiner box BM series fuse block Surge protection devices + NH Style photovoltaic fuse links and fuse holders XL Style photovoltaic fuse links and fuse bases Square body, BS and UL High speed fuse links NH Low voltage fuse links and fuse holders 4 EATON Bussmann series photovoltaic application guide DC Disco Solar modules Combiner box Array protection Inverter protection onnect DC Disconnect DC/AC Inverter AC Disconnect Transformer Array combiner box onnect EATON Bussmann series photovoltaic application guide 5 Introduction With the rising energy costs of fossil fuels and their impact on the environment, the focus on renewable energy has gained strength, which has led to an increase in the size of Photovoltaic (PV) installations from 1.4 GW in 2000 to 137 GW in 2013. This rapid growth in PV installations has challenged system designers, manufacturers and standards organizations due to the special demands associated with PV installation in terms of current, voltage, and ambient temperature. These requirements have also been considered in the development of international protection standards for PV installations, which Eaton’s Bussmann business, the leading name in electrical protection, has used to develop PV specific protection devices. 60,000 50,000 40,000 30,000 20,000 10,000 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 Global annual photovoltaic installations (Megawatt). Source: EPIA IEC 60269-6 gPV standard Unlike typical grid connected AC systems, the available shortcircuit current within PV systems is limited and the overcurrent protective devices need to operate effectively on low levels of fault current. For this reason Eaton’s Bussmann business has conducted extensive research and development of fuse links that are specifically designed and tested to safely protect PV systems with high DC voltages and low fault currents. The International Electrotechnical Commissions (IEC) recognise the protection of PV systems is different to standard electrical installations. This is reflected in IEC 60269-6 which defines specific characteristics that a fuse link is required to meet for protecting PV systems, utilisation class gPV. Eaton’s Bussmann series range of string and branch PV fuse links has been specifically designed to meet this standard. However, Eaton’s Bussmann series PV fuse links exceed the requirements of IEC 60269-6 as they operate at 1.35 x In (1.35 times the nominal current). They also meet the requirements of UL 2579 and are thus suitable for protecting PV modules in reverse current situations. Whilst the standard does not recognise a specific symbol, the combination of the symbols for fuse link and strings are often used to indicate a fuse link is suitable for protecting strings in PV systems, see Figure 1. Figure 1 6 EATON Bussmann series photovoltaic application guide Photovoltaic module construction • A photovoltaic (PV) cell is usually between 4” and 6” square. • A number of individual cells are combined in a module (often called a panel). • A number of PV modules in series is referred to as a string. • A number of strings in parallel is referred to as an array. Figure 2 Photovoltaic module output The voltage output of a PV module is defined by the number of cells in series that form the module. The current output of a PV module is dependent on the area of a cell. The most widely used solar modules are made with 4’’, 5’’ and 6’’ poly-crystalline silicon cells. This type of module using 6’’ cells, can achieve approximately 8 Amps maximum power point (MPP) current per module with a typical voltage output of around 30 Volts. With thin film technology typical output is 2.5 Amps and 40 Volts. The maximum power point current of the modules vary between manufacturers of equal solar cell dimensions. When selecting the appropriate fuse links, the specified Short Circuit Current (Isc) and reverse current characteristics specified by the manufacturers should be used. The specifications provided by the module manufacturer should be consulted to confirm the output currents and voltages of the modules under the range of conditions expected for the proposed installation. These conditions are influenced by the ambient temperature, the incident angle of sunlight and the amount of solar energy reaching the module. These are usually mentioned as coefficients on the manufacturer’s specifications. Manufacturers also suggest the maximum series fuse rating or a reverse current rating. Both of these are based on modules surviving 1.35 time this rating for two hours. EATON Bussmann series photovoltaic application guide 7 Overview of string protection Depending on the desired capacity of the Photovoltaic (PV) system, there may be several PV strings connected in parallel to achieve higher currents and subsequently more power. PV systems that have three or more strings connected in parallel need to have each string protected. Systems that have less than three strings will not generate enough current to damage the modules in the event of a fault. Therefore they do not present a safety hazard, provided the conductor is sized correctly, based on local codes and installations requirements. Where three or more strings are connected in parallel, a fuse link in each string will protect the cables and modules from overcurrent faults and help minimise any safety hazards. It will also isolate the faulted string so that the rest of the PV system can continue to generate electricity. It should be remembered that PV modules current output changes with the module temperature as well as the amount of sun they are exposed to. The exposure is dependant on irradiance level, incline as well as shading effect from trees, buildings or clouds. In operation, fuse links, as thermal devices, are influenced by ambient temperature. The current capability of Eaton’s Bussmann series PV string fuse link should be derated according to the curves below.

These cover most variations due to installation. The same method should be adopted for crystalline and thin film modules.If your PV installation is subject to extremes of high altitude, high irradiance, or low temperature, please consult Eaton’s Bussmann business technical team ([email protected]).

A fuse link on each array will protect the cables from fault current and help minimise any safety hazards. It will also isolate the faulted array so that the rest of the PV system can continue to generate electricity. A fuse link positioned in the cable that carries the combined output of a number of strings should be protected by array fuse links. If a number of arrays are subsequently combined then a further fuse link should be incorporated. It should be remembered that the characteristics of PV modules vary with module temperature as well as irradiance level. In operation fuse links are influenced by ambient temperature.
