Ungalikhetha Kanjani Ibhokisi Elilungile Lentambo Yentambo Yelanga Yesistimu ye-PV?

Ngemva kokukhetha amaphaneli elanga, izintambo ze-PV, ama-inverter namanye amabhethri noma amathuluzi okugcina, awufuni ukucekela phansi ngephutha ukusetha kwakho konke ngokukhetha ibhokisi lesihlanganisi elingalungile.Lapho ukhetha ibhokisi lokuhlanganisa intambo yelanga, uhlobo, usayizi nobubanzi bephrojekthi kubalulekile, futhi lokho okusebenza kangcono ekufakweni kwezindawo zokuhlala kungase kungasebenzi ekufakweni kwezentengiso, futhi ngokuphambene nalokho.

Ukukhetha ibhokisi lentambo yelanga elilungile lesistimu yakho ye-PV akunzima, kodwa kufanele uqonde isayithi, amanye amamojula we-PV kanye nobudlelwano bawo nebhokisi lesihlanganisi.

Yini I-Solar Panel Combiner Box?

Amabhokisi okuhlanganisa amaphaneli elanga ahlanganisa amandla angenayo abe okuphakelayo okukodwa okuyinhloko, bese kusakazwa kuma-inverter elanga.Ngokunciphisa izintambo, izindleko zabasebenzi kanye nezinto ezibonakalayo ziyancipha.Isihlanganisi sephaneli yelanga sinokuvikeleka okwakhelwe ngaphakathi kwe-overcurrent kanye ne-overvoltage ukuze sithuthukise ukuvikeleka nokuthembeka kwe-inverter.

Inhloso yebhokisi lokuhlanganisa ilanga ukuhlanganisa izintambo zamaphaneli elanga zibe ibhokisi elilodwa.Iyunithi yezinhlamvu ngayinye ixhunywe kutheminali ye-fuse, futhi okukhiphayo kwetheminali ye-fuse kugoqwa kube ikhebula elingena ebhokisini le-inverter.Lona umsebenzi oyisisekelo kakhulu wesihlanganisi selanga, futhi ungathuthukiswa ngezici ezengeziwe njengezinkinobho zokuvala ngokushesha namadivayisi okuqapha.

Kukhona ibhokisi lokuhlanganisa i-solar PV phakathi kwe-inverter namaphaneli elanga.Indawo yebhokisi lesihlanganisi selanga le-PV kufanele ibe yinto eza kuqala, njengoba ukubekwa okungafanele kungase kubangele ukulahlekelwa ukusebenza kahle kukagesi, futhi ibhokisi lokuhlanganisa le-PV alidingeki ezindlini ezingenazintambo ezingaphezu kwezintathu.Isakhiwo sibalulekile njengoba isihlanganisi se-PV esibekwe endaweni engaphansi kwendawo ekahle singaholela ekwenyukeni kwezindleko ze-DC BOS ngenxa yokulahleka kukagesi namandla.

Kulula Kangakanani Ukumisa?

Sekukonke, ibhokisi lokuhlanganisa le-DC elifanele livame ukuncika ekusetshenzisweni kwalo kalula nasekulifakeni, kanye nenkinga elisusayo kuphrojekthi.Amabhokisi anezibambi ze-fuse ezinezintambo zangaphambili ezinezinsika zengulube angaba isixazululo se-plug-and-play esingadingi ukuthi umuntu osebenza ngogesi onelayisense ayifake.

Isibonelo, i-Slocable ikhiphe Isixazululo sayo se-Integrated DC Combiner Solution (ICS), isixazululo sokuma okukodwa esihlanganisa izintambo zangaphambili, izindlala zekhebula ezikhululayo, amabhulokhi okusabalalisa amandla aphephile ngokuthinta kanye nezibambi ze-fuse zezindlela ezimbili.Uma songa isikhathi esiningi nezindleko ngesixazululo se-turnkey esilula nesingenzeka, abafaki bazosihlanganisa kuyo yonke iphrojekthi.

Imuphi Umsebenzi Ibhokisi Lenhlanganisela Ye-PV DC Lidingayo?

Uma ukhetha ibhokisi lokuhlanganisa le-PV DC lehla ngentengo nokutholakala.Ekufakweni kwezindawo zokuhlala, kunezixazululo ezingekho eshalofini ezihlanganisa ukucushwa okungaba khona okuhlukahlukene, ukonga isikhathi nezindleko ezengeziwe ezihilelekile nezixazululo ezenziwe ngokwezifiso.

Nokho, ngezakhiwo eziningi ezihlukene zamaphaneli, futhi kuye ngezinye izingxenye zesistimu, isihlanganisi se-PV singase sidinge ukwenza okungaphezu komsebenzi oyisisekelo wokuhlanganisa amasekhethi namafusi.Akuwona wonke umkhiqizi onebhokisi lokuhlanganisa le-solar DC elingekho eshalofini laso sonke isimo.Ingabe udinga ukuguquguquka, noma ubulula nje?Ake sithi unamasistimu elanga amabili ahluke ngokuphelele angena ebhokisini elifanayo le-solar DC futhi adubule ukuze ahlukanise izilawuli.Amanye amabhokisi esihlanganisi angakwazi ukuphatha lokhu, kanti amanye angase adinge ukwenziwa ngokwezifiso.

Esikhathini esedlule, wonke ama-inverter ayevele asekelwe phansi, futhi abafakeli babewafanisa ebhokisini le-solar PV yohlelo ngaphambi kokuwaxhuma kusiguquli.Ama-inverter angenasisekelo angenasisekelo manje ayatholakala, adinga isifaki ukuthi sihlanganise isigxobo esinegethivu.Lesi sakhiwo siyinkimbinkimbi futhi sidinga ibhokisi lokuhlanganisa le-PV ukuze lizibambe zihlangane.

Ngaphambi kokukhetha isihlanganisi se-PV array, kufanele uqale unqume inverter - iyiphi inverter ongayisebenzisa?Ngezinketho eziningi kangaka ze-inverter, kusukela kuma-inverter ezintambo zendabuko kuya ku-transformerless kanye ne-transformerless ene-MPPT yamashaneli amabili, kudingeke ukuthi sinciphise ibhokisi lesihlanganisi esithobelayo esivumelana nencazelo ukuze sibe nezixazululo eziningana ezihlanganisa konke ukulungiselelwa.

Uma isekelwe phansi, ihambisana nesitayela sakudala somugqa oqondile.Uma ingenaso i-transformer, i-negative kumele ihlanganiswe futhi ikwazi ukunqamula okunegethivu nokuphozithivu.Bese kuba nosayizi we-inverter, ama-inverter amaningi manje akhuphukela ku-1000V futhi udinga ibhokisi le-PV lamalungu ukuze lifane.

Futhi, amanye amabhokisi enhlanganisela ye-solar angakwazi ukuphatha imisebenzi eminingi.Isibonelo, i-MNPV8HV ye-MidNite ingenza izinto ezintathu ngesikhathi esisodwa ekucushweni okukodwa: ngokuhambisana ngokuqondile, bese idubula iziguquli ezimbili ezihlukene.Kungenjalo, ibhokisi lesihlanganisi lamalungu afanayo lingaphatha ukusebenza kwe-transformerless futhi lifake ama-negative amane kanye namaphozithivu amane.

Abanye abakhiqizi bangakwazi ukuhlanganisa ubuchwepheshe bokuqapha okungenantambo bawenze amabhokisi okuhlanganisa amasistimu sonozungezilanga, okuvumela izinga lephaneli kanye neleveli yezintambo zamanje, i-voltage, nokuqapha izinga lokushisa.Ngaphezu kwezinzuzo zako ezingokwemvelo phakathi nokufakwa, ukuqapha kunikeza impendulo yesikhathi sangempela ngesikhathi sokusebenza kwenkambu.Ngale ndlela, izinkinga zingabonakala kwasekuqaleni futhi amaphutha amakhulu angavinjelwa esikhathini esizayo.Kunesici sephutha lomuntu kunoma iyiphi iphrojekthi yokwakha, futhi ukuhlola ngokucophelela kungagwema izindleko eziningi ezingadingekile.

Ibhokisi lokuhlanganisa ugesi lidinga ukulungiswa okuncane, futhi izinga lokunakekelwa kufanele linqunywe indawo ezungezile kanye nemvamisa yokusetshenziswa.Kungumqondo omuhle ukuwahlola njalo ukuthi awavuzi yini noma awaxhumekile, kodwa ibhokisi lesihlanganisi elifakwe kahle kufanele lelule impilo yephrojekthi yakho yelanga.Ikhwalithi iwukucatshangelwa okubaluleke kakhulu lapho ukhetha ibhokisi lokuhlanganisa i-photovoltaic, ikakhulukazi njengoba liwucezu lokuqala lwemishini exhunywe ekuphumeni kwe-module yelanga.Izihlanganisi ze-Photovoltaic azibizi uma ziqhathaniswa nezinye izingxenye zephrojekthi yelanga, kodwa ibhokisi lokuhlanganisa elingalungile lingaholela ekuhlulekeni okukhulu njengomlilo nentuthu.

Ingabe Ngidinga Ibhokisi Lenhlanganisela Yentambo ye-PV?

Ngokuya ngezinye izinto ezisetshenziswayo, ezinye izindawo ziyakwazi ukuxhuma yonke into ngaphandle kokusebenzisa ibhokisi lokuhlanganisa izintambo ze-PV.Kumaphrojekthi anezintambo ezimbili noma ezintathu kuphela (isb. izindawo zokuhlala ezivamile), amabhokisi okuhlanganisa izintambo awadingeki, futhi adingeka kuphela kumaphrojekthi amakhulu, asukela kuzintambo ezingu-4 kuye kwezingu-4,000.Ngakolunye uhlangothi, izihlanganisi zezintambo zingazuza kumaphrojekthi abo bonke osayizi.

Amabhokisi okuhlanganisa izintambo ze-DC angaletha inani elilinganiselwe lezintambo endaweni eyodwa ukuze zifakwe, zinqanyulwe futhi zilungiswe ezinhlelweni zokuhlala.Amabhokisi enhlanganisela ye-DC anosayizi abahlukene avame ukusetshenziswa ezinhlelweni zezentengiselwano ukuvuna amandla ezakhiweni zokwakha.Amabhokisi enhlanganisela avumela abahleli besayithi ukuthi bathuthukise amabhokisi amandla kuyilapho behlisa izindleko zezinto ezibonakalayo zamaphrojekthi esikali sokusetshenziswa.

Ibhokisi lokuhlanganisa amandla elanga elibiza ngaphansi kwamadola angamakhulu ambalwa lengeza inani elikhulu kusistimu yakho sonozungezilanga—izintambo ezimbalwa, ukusebenza kahle okuphezulu, ukunqanyulwa kwezimo eziphuthumayo, nokuphepha okuthuthukisiwe.Abagcini nje ngokuba nalezi zinzuzo, kodwa futhi kulula ukusetha.Uma uneminye imibuzo mayelana nebhokisi lesihlanganisi samandla, ungaxhumana nathi, i-Slocable izokunikeza isisombululo esihle kakhulu kanye nentengo engcono kakhulu!
