Uzwa "uchungechunge lwe-Photovoltaic" bese ucabanga ngokushesha amaphaneli wokugcina we-wired-ekugcineni. Futhi yebo, yilokho kuphela. Kepha ngokweqiniso, kulapho amasistimu amaningi kangaka ahlelwe khona ngaphambi kokuba aqale ngempela. Akukona nje ukushaya i-voltage okuhlosiwe nge-inverter yakho; Kumayelana nokusebenza kokulinganisa, okulindelekile umthunzi, futhi ngokungananazi, okwenza yonke le nto inengqondo ngokomnotho. Ngibone ezinye zezinhloko zangempela, futhi ngifunde izinto ezimbalwa ngendlela enzima.

Umqondo oyisisekelo - futhi lapho kuba khona ngamatshe

Ngakho-ke, a Uchungechunge lwe-Photovoltaic intambo. Okuhle Okuyisisekelo: Uxhuma i-terminal enhle yemodyuli eyodwa kwi-terminal engemihle yalandelayo, futhi uyaqhubeka. Ukuhlala kwamanje okufanayo ngaphesheya kwentambo, kepha ama-voltages angeza. Isimo esihle, kunjalo? Onke amamojula ayafana, ethola ilanga elifanayo, izinga lokushisa elifanayo. Emhlabeni wangempela? Akukaze kwenzeke. Angikaze. Unokukhiqiza ukubekezelela, umjondolo omncane ovela ku-chimney noma i-vent, ukuqongelela uthuli - ngisho nokwehluka okucashile ku-pitch yophahla kungadala ukunganaki okungalingani. Zonke lezi zinto ziqala ukudonsa phansi ukusebenza kwayo yonke intambo, kwesinye isikhathi kakhulu.

Iphutha elilodwa elijwayelekile engilibonile, ikakhulukazi elinabafakeli abanolwazi oluncane, umane nje ukugxusha amamojula amaningi ngangokunokwenzeka ngentambo yokushaya iwindi le-voltage eliphakeme le-Inverter. Kubukeka kahle ephepheni, izintambo ezimbalwa zisho i-wiring encane, kunjalo? Kepha bese ugijimela izingqinamba ngezinsuku ezibandayo lapho i-open-circuit Voltage Voltage Voltage (VOC) SPIKES. Uma uyicindezela eduze kakhulu ku-Inverter's Absolute Max, uyazibeka engcupheni yokuyikhipha noma uyilimaze. Udinga indlu yekhanda, njalo. Cabanga ngalabo ekhrisimuli, ukusula ekuseni ebusika; Yilapho ubona ama-voltages akho aphezulu. Udinga ngempela ukukhombisa leso simo esibi kakhulu.

Sake saba nomsebenzi lapho iklayenti ligcizelele khona ukukhulisa ubude bentambo ukunciphisa ukusetshenziswa kwebhokisi le-combiner. Kwakubonakala kunengqondo ngaleso sikhathi. Kepha amamojula ayenokuhlukahluka okuhlukile ngenxa yomugqa onzima wophahla. Lokho esikuthole kwakuyindaba ye-classic yokulahleka kwezintambo. Lonke uhlelo lungakhathazeki, futhi kwathatha ukuxilonga okuningi ukululandela. Ngokubheka emuva, kufanele ngabe sicindezele kanzima ukuthola izintambo eziningi, ezimfishane, noma ngabe kusho ukuthi i-wiring eningi nezindleko eziphakeme kakhulu eziphambili. Kwesinye isikhathi, umzamo omkhulu ophambili usindisa ikhanda elikhulu lekhanda. Akukona nje mayelana ne-wiring; Kumayelana nokusebenza kwezinga le-module

I-String Design: Hhayi ngosayizi owodwa

Lapho uklama eyakho Uchungechunge lwe-Photovoltaic, awugcini nje ukukhetha inombolo esihlokweni. Ulinganisa ibanga eliphakeme le-Inverter Point Point Track Futhi-ke uphonsa ngezimpawu zemodyuli: I-Imp, VPP, VOC, kanye ne-lokushisa lokushisa. Lawo ma-coefficients okushisa abalulekile - athi akutshele ukuthi malini amandla azokwehla ngezinsuku ezishisayo (ukunciphisa amandla) futhi akhuphuke ngezinsuku ezibandayo (ngokusenza imikhawulo ye-voltage).

Ngokwesibonelo, uma usebenzisa i-inverter yentambo, ukuba nawo wonke amamojula ku Uchungechunge lwe-Photovoltaic I-String ibhekene nendlela efanayo, ngaphandle komthunzi obalulekile, muhle kakhulu ongaxoxi ngokusebenza kahle. Ama-inver-inverters noma ama-optimizers axazulula lokhu ngezinga elithile ngokuvumela i-MPPT ye-Module-Level, kepha leyo yingxoxo ehlukile. Lapho ukhuluma ngokuqinile izintambo, noma iyiphi imodyuli kuleyo ntambo engasebenzi kahle ngenxa yomthunzi noma iphutha izosebenza njengebhodlela lentambo yonke. Kufana neketanga; Kuqine kuphela njengesixhumanisi sayo esibuthakathaka. I-Bypass Diode isiza, isiqiniseko, kepha ayibenzi ngomlingo ukwenza imodyuli enomthunzi ikhiqize amandla.

Ngemuva kweminyaka embalwa, sasihlosa uhlelo lwesakhiwo sezentengiselwano. Uphahla lwalunamayunithi amaningana ama-hvac ukuthi, ngenkathi engahlangene ngokuqondile amaphaneli omningi wosuku, abeke amathunzi amade ngezikhathi ezithile, ikakhulukazi ebusika. Siqale sakha izintambo ezimbalwa kakhulu. Ngesikhathi sokukhomisha, siqaphele amaconsi aphezulu kandla ekuseni naku-ntambama. Kuvela, ngisho nesithunzi esiyingxenye emgede ngaphesheya kwemiphetho engezansi yamamojula ambalwa ngentambo kwanele ukungqongqoza okubonakalayo okubonakalayo kokuphuma kwezintambo. Siqede ukwenza kabusha izigaba ezithile, siphula lezo zintambo ezinde zibe ngamafuphi, futhi zisebenzisa okokufaka okuhlukile kwe-MPPT kwi-inverter ukunciphisa umphumela. Kwakuyisifundo esibizayo ekuhlaziyweni kwesithunzi. Udinga ngempela ukuhamba isiza, imephu amathunzi, futhi ngeso lengqondo ukuthi bazokuhamba kanjani usuku lonke nonyaka.

Ukuthembeka nokunakekelwa kwesondlo

Ngokombono wokuthembeka, wakho Uchungechunge lwe-Photovoltaic ukuxhumana kubalulekile. Zonke izixhumi ze-crimp, zonke izixhumi ze-MC4, konke ukuxhumeka kwebhokisi lokuhlangene kuyiphuzu lokuhluleka. Ngibone izindaba ezingenakubalwa zilandelwa emuva ekuxhumaneni kahle - amakhemikhali aphoqelekile, izintambo ezingekho emthethweni, noma izixhumi ezishibhile ezincipha ngaphansi kokuvezwa kwe-UV. Lokhu akuwona nje ukucasulwa okuncane; ziyizingozi zomlilo esimweni esibi kunazo zonke, futhi nakanjani zidonsa kanzima ezimeni ezinhle kakhulu.

Yilapho ikhwalithi yezakhi zibaluleke ngempela ngempela. Sihlale sikwenza kwaba yiphuzu ukusebenzisa abahlinzeki abadumile ngezixhumi zethu nezintambo. Awukwazi nje ukubiza lapho. Kuyalinge ukunciphisa izindleko, kepha okusindisa ngokwezinto ezibonakalayo, uzokhokhela ukuvikelwa okungumbala kokuxazulula inkinga, ukulungiswa kanye nesizukulwane esilahlekile. Ukukhuluma ngekhwalithi, ama-fasteners angenye indawo ebucayi yephazili, ebambe konke ndawonye. Sisebenze naye I-Handan Zitai Fetesser Comment Co, Ltd. Iminyaka, ikakhulukazi ama-bolts awo akhethekile nezinye izingxenye zezakhiwo ezidingekayo kulezi zinhlobo zokufakwa kwezinga elikhulu. Imikhiqizo yabo ihlala ihambelana, futhi ngokweqiniso, ukuthi ukuthembeka kuyingxenye enkulu yokuqinisekisa isikhathi eside sohlelo lonke. Akuwona nje amaphaneli nabasekeli; Konke kukodwa, i-bolt, kanye ne-washer okudinga ukumelana nezinto.

Isondlo ohlelweni olususelwa enhlanganisweni luvame ukubandakanya ukuthola lezi zinhlobo zezingqinamba zokuxhumana noma ukukhomba amamojula angaphansi komhlaba. Amakhamera we-infrared ahle kakhulu ngokubona izindawo ezishisayo, ezivame ukukhombisa i-diode yehlulekile ye-diodi noma iseli elinephutha. Kodwa ngisho nangaphambi kwalokho, ukwazi nje ama-voltages akho alindelekile nemisinga, futhi ubabheka njalo, kungakunika izexwayiso zakuqala. Uma intambo eyodwa iphansi kunabanye, uyazi ukuthi ungaqala kuphi ukubheka. Konke mayelana nokunaka imininingwane. Ukufakwa kokuqala kubalulekile; Noma iziphi izinqamuleli ezithathwe lapho zizokukhathaza iminyaka.

Ikusasa le-Stringing: Amamojula ahlakaniphile kanye ne-MLPE

Ngenkathi umqondo oyisisekelo we Uchungechunge lwe-Photovoltaic I-String ayiyi ndawo, ukuthi sikuphatha kanjani futhi sandisa lezo zintambo zivela ngokushesha okukhulu. Amamojula we-Smart anama-optimizer ahlanganisiwe noma ama-inverters ahlanganisiwe aya ngokuya evame kakhulu, eshintsha ngempumelelo imodyuli ngayinye ibe nguPPPT oyedwa. Lokhu kunciphisa kakhulu umthelela we-shading kanye nokungaziphathi kahle, okwenza ama-string aklama kancane ukuthethelela okuthethelelayo, yize kwethula ama-elekthronikhi amaningi ngemodyuli ngayinye. Kuyinto yokuhweba: izakhi eziningi, kepha ukusebenza okungcono futhi kuvame ukutholakala iphutha elilula ezingeni lemodyuli.

Ngisho nalezi zithuthuka, ukuqonda izisekelo zezinkampani ezisebenza ngentambo namanje kubaluleke kakhulu. Usadinga ukusayizi in-inverter yakho kahle, i-akhawunti yokuhluka kokushisa, futhi uqinisekise ukuthi i-wiring yakho iqinile. Ubulukhuni bushintsha, kepha akunyamalali. Okwezentengiso ezinkulu kwezentengiso, ibhalansi phakathi kobude bentambo, usayizi we-inverter, kanye nokusetshenziswa kwe-module Level Power Electronics (MLPE) iba ngumsebenzi wobunjiniyela obukhulu. Uhlala ubheka leyo ndawo emnandi phakathi kokuvunwa kwamandla okukhulu, ukuthembeka kohlelo, nokusebenza kwezindleko ngokuphelele. Futhi yilokho empeleni okubilayo uku: ukuthola ama-elektroni amaningi ngebhadi, ngokuthembekile, amashumishumi eminyaka.
