Guhitamo uburenganziraumugozi w'amashanyarazini imwe mu ntambwe zingenzi mu kubaka ingufu zituruka ku mirasire y'izuba itekanye kandi ikora neza. Ingano yukuri ya kabili, igipimo, nibikoresho bigira ingaruka kumikorere ya sisitemu, gutakaza ingufu, hamwe nigihe kirekire - kwizerwa. Hamwe nimiyoboro myinshi ya PV hamwe namahitamo arahari, gusobanukirwa icyo ugomba kureba bigufasha kwirinda amakosa ahenze. Aka gatabo gasobanura uburyo bwo guhitamo umugozi mwiza ukoresheje ibintu bifatika, amakuru - ashyigikiwe.
Ni ubuhe bwoko bw'insinga zikoreshwa muri sisitemu y'izuba kandi niyihe nkeneye?
Imirasire y'izuba ikoresha insinga yihariye ya Photovoltaque (PV) kuruhande rwa DC hamwe na AC - zisanzwe zagabanijwe kumurongo wa inverter / ibisohoka kuruhande. Ubwoko busanzwe bwa PV burimo PV1 - F (nanone bita insinga ya PV cyangwa insinga yizuba) hamwe ninsinga zakozwe kuri IEC 62930 / EN 50618. Izi ni umusaraba - uhuza insinga zagenewe gukorerwa hanze ya UV hanze, ubushyuhe bwinshi, hamwe nuburebure - igihe cyogukoresha imashini / imiti - imitungo insinga zubaka zisanzwe ntizishobora gutanga. Koresha PV - insinga zagabanijwe kuri module - kugeza - guhuza hamwe numugozi - to-combiner ikora; koresha neza AC itwara neza nyuma ya inverter.
Nigute nahitamo ingano yubuyobozi bukwiye (AWG / mm²)?
Tora ingano yuyobora mugenzura inzitizi ebyiri:ampacity (ubushobozi bwo gutwara)naUmuvuduko wa voltage.
Ampacity: Ingano yubuyobozi kugirango ikore byibuze 125% yumurongo wa PV ntarengwa uhoraho (NEC iyobora imiyoboro ya PV), hanyuma ukoreshe ibintu byo gukosora byaho kubushyuhe no guhuriza hamwe. Ibi birinda ubushyuhe bwinshi kandi byujuje code. Enkonn Solar
Umuvuduko w'amashanyarazi: Kumurongo muremure wa DC, kugabanuka kwa voltage bitera gutakaza imbaraga nyazo (no gutakaza imikorere ya sisitemu). Abashushanya mubisanzwe bagabanya imbaraga za DC kugabanuka kugeza ku gipimo gito (urugero, 1-3%). Koresha amashanyarazi akomoka ku mirasire y'izuba - kubara imashini cyangwa umugozi - igikoresho kinini kugirango ugereranye amahitamo ya AWG / mm² bitandukanye na ampacity hamwe namategeko yo guta. Imirasire y'izuba +1.Amategeko yihuse - ya - igikumwe (ntabwo gisimburwa kubara): kumugozi mugufi uyobora (<10 m) on 12–24 V systems, use thicker cable; on typical 48–600 V PV strings, #10–#6 AWG (6–10 mm² range) is commonly used depending on current and run length - always confirm with a specific calculation and local code.
GuraImirasire y'izuba, saba urupapuro rwerekana urupapuro rwabigenewe, kandi ubike inyandiko za garanti / kugenzura.
Ni ubuhe bushyuhe, UV, na voltage byerekana akamaro?
Ikigereranyo gikomeza ubushyuhe bwumuvuduko kuri dogere cyangwa hejuru ya dogere 90 (insinga nyinshi za PV zapimwe kuri dogere 90 cyangwa zirenga).
Kurwanya UV hamwe nizuba ryizuba - jacketi yagenwe kugirango igaragare hejuru yinzu (PV1-F / EN 50618 / IEC 62930).
Umuvuduko w'amashanyarazi urenze sisitemu ya sisitemu ntarengwa yo gukora - insinga za PV zigezweho zisanzwe zigera kuri 1.5 kV DC kubikorwa byingirakamaro hamwe nubucuruzi (IEC 62930 bitwikiriye 1.5 kV). Urubuga rwa IEC +1
Gukoresha umugozi ufite ubushyuhe budahagije, UV, cyangwa igipimo cya voltage rishobora kwihuta gusaza, gusenyuka, no kurenga kode.
Tuvuge iki ku bahuza - MC4 no guhuza?
Koresha inganda - zisanzwe, UV - zapimwe PV ihuza (MC4 cyangwa imiyoboro ihuza) kuri module - kugeza - module na module - kugeza - kuyobora. Menya neza ko abahuza bapimwe neza mugupima umugozi wahisemo kandi nukuri (abahuza impimbano barashobora gutera umubano mubi, gushyuha cyane, cyangwa kwinjira mumazi). Kurikiza itara ryumushinga uhuza hanyuma ushireho - amabwiriza yubutabazi hanyuma ushireho umugozi muri ~ 20 mm ya boot ihuza kugirango urinde umuyobozi.
ntushobora gukoresha umuringa usizwe, ucuramye cyangwa uyobora?
Umuringa uhagazeirasabwa cyane kubikoresho bya PV kuberako isahani yamabati igabanya ruswa (ingenzi mubice bitose / ku nkombe) kandi abayobora bahagaze batanga uburyo bworoshye bwo guhuza no guhuza. Imiyoboro ihamye ntisanzwe kubikoresho bya PV module kuko biragoye kunyura munzira kandi bikunze kuvunika mubihe bihindagurika / byoroshye. Imiyoboro myinshi ya PV - izana hamwe nu muringa ucometse neza, uhagaze neza.
Nigute code n'ibipimo bigira ingaruka kubyo ngura?
Kode y'amashanyarazi yaho (urugero, NEC muri Amerika, IEC / EN mubindi bihugu byinshi) itegeka ubushobozi bwuyobora, kurinda birenze urugero, imipaka ya voltage, igipimo cyubushyuhe, uburyo bwo kwishyiriraho, hamwe no kwemeza abahuza. Kurugero, NEC (Ingingo ya 690) ifite ibisabwa byihariye kugirango ubunini bwa PV buringaniye hamwe na voltage ntarengwa ya sisitemu; mu Burayi no ku masoko menshi ku isi, IEC 62930 na EN 50618 bagaragaza kubaka insinga za PV no kugerageza. Gura insinga zifite ibyemezo bifatika (UL 4703, TÜV, EN 50618, IEC 62930) kugirango woroshye kwemeza ubugenzuzi nigihe kirekire - kwizerwa.
Nigute Wamenya Uburyo bwo Guhitamo Umugozi Ukwiye wa Sisitemu Yizuba?
