I-Solar Panel Cables nezixhumi Zixhumeka kanjani ku-PV Module?

Iningi lamaphaneli elanga anamandla aphezulu akhiwe ngamakhebula e-PV anezixhumi ze-MC4 ekugcineni.Eminyakeni edlule, amamojula e-solar PV ayenebhokisi le-junction ngemuva kanye nezifaki ezidingekayo ukuze kuxhunywe amakhebula ngesandla kumatheminali avumayo noma angalungile.Le ndlela isasetshenziswa, kodwa kancane kancane iqedwa.Amamojula welanga anamuhla ajwayele ukusebenzisaAmapulagi we-MC4ngoba benza ukuhlanganisa izintambo ze-PV kube lula futhi kusheshe.Amapulagi e-MC4 ayatholakala ngezitayela zabesilisa nabesifazane ukuze zishuthwe ndawonye.Zihlangabezana nezidingo ze-National Electrical Code, zifakwe ohlwini lwe-UL, futhi ziyindlela yokuxhuma ekhethwayo yabahloli bakagesi.Ngenxa yomshini wokukhiya wezixhumi ze-MC4, azikwazi ukukhishwa, okuzenza zilungele izindawo zangaphandle.Izixhumi zinganqanyulwa ngesipesheliIthuluzi lokunqamula le-MC4.

Ungawafaka Kanjani Izintambo I-MC4 Efakwe Amaphaneli Elanga Ochungechungeni?

Uma unamaphaneli elanga amabili noma ngaphezulu azoxhunywa ochungechungeni, ukusebenzisa isixhumi se-MC4 PV kwenza uchungechunge lube lula.Bheka imojula yokuqala ye-PV esithombeni esingezansi futhi uzobona ukuthi inezintambo ezimbili ze-solar PV ezinwebeka ebhokisini lokuhlangana.Intambo eyodwa ye-PV ithi DC positive (+) kanti enye inegethivu ye-DC (-).Ngokuvamile, isixhumi sowesifazane se-MC4 sihlotshaniswa nekhebuli ephozithivu futhi isixhumi sowesilisa sihlotshaniswa nekhebuli eyinegethivu.Kodwa lokhu kungase kungabi njalo, ngakho-ke kungcono ukuhlola izimpawu ebhokisini le-PV junction noma usebenzise i-voltmeter yedijithali ukuhlola i-polarity.Uxhumano oluwuchungechunge yilapho ukuhola okuhle kuphaneli yelanga eyodwa kuxhunywe kumthofu ongemuhle kwenye iphaneli yelanga, isixhumi sowesilisa se-MC4 sizongena ngqo kusixhumi sowesifazane.Umdwebo ongezansi ubonisa ukuthi amamojula e-MC4 axhunywe kanjani ochungechungeni:

Njengoba kubonisiwe, ama-solar panel amabili axhunywe ochungechungeni ngemikhondo emibili, okwandisa i-voltage yesifunda.Isibonelo, uma amamojula akho e-PV akalwe ku-18 volts ngamandla amakhulu (Vmp), lapho-ke amabili awo axhunywe ochungechungeni angaba ngu-36 Vmp.Uma uxhuma amamojula amathathu ochungechungeni, ingqikithi ye-Vmp izoba ngu-54 volts.Uma umjikelezo uxhunywe ochungechungeni, amandla aphezulu wamanje (Imp) azohlala efana.

Ungawafaka Kanjani Izintambo I-MC4 Efakwe Amaphaneli Elanga Ngokuhambisana?

Izintambo ezihambisanayo zidinga ukuxhuma izintambo eziphozithivu ndawonye kanye nezintambo ezinegethivu ndawonye.Le ndlela izokhuphula i-current at maximum power (Imp) ngenkathi igcina i-voltage ingashintshi.Isibonelo, ake sithi amaphaneli akho elanga alinganiselwe ku-8 amps Imp, kanye no-18 volts Vmp.Uma ezimbili zazo zixhunywe ngokuhambisana, ingqikithi ye-amperage izoba ngu-16 amps Imp futhi i-voltage izohlala ku-18 volts Vmp.Lapho uxhuma amaphaneli elanga amabili noma ngaphezulu ngokuhambisana, uzodinga imishini eyengeziwe.Uma usebenzisa amaphaneli elanga amabili kuphela, indlela elula ukusebenzisa i-solarIsixhumi segatsha se-MC4.Ngokusobala, awukwazi ukuxhuma izixhumi ezimbili zabesilisa noma izixhumi ezimbili zabesifazane ndawonye, ​​ngakho sizokwenza lokho ngesixhumi segatsha se-PV.Kunezixhumi ezimbili zamagatsha ezihlukene.Uhlobo olulodwa lwamukela izixhumi ezimbili zesilisa ze-MC4 ohlangothini lokokufaka futhi lunesixhumi esisodwa sowesilisa se-MC4 sokukhiphayo.Olunye uhlobo lwamukela izixhumi ezimbili zesifazane ze-MC4 futhi lunesixhumi esisodwa sowesifazane se-MC4 sokukhiphayo.Empeleni, unciphise inani lamakhebuli ukusuka kokubili okuphozithivu namabili kunegethivu kuya kweliphozithivu nelodwa elinegethivu.Njengoba umdwebo uboniswe ngezansi:

Uma uqhathanisa amamojula e-PV angaphezu kwamabili noma izintambo ezifanayo zamamojuli, udinga ibhokisi lokuhlanganisa le-PV.Ibhokisi lesihlanganisi linomsebenzi ofanayo nesixhumi segatsha lelanga.Izixhumi zamagatsha elanga zifaneleka kuphela ukuxhuma amaphaneli elanga amabili ngokuhambisana.Isamba senani lamaphaneli elanga angahlanganiswa azoncika ezilinganisweni zikagesi kanye nobukhulu bomzimba bebhokisi lesihlanganisi.Kungakhathaliseki ukuthi uxhuma amaphaneli akho elanga ngezixhumi zegatsha noma amabhokisi okuhlanganisa, udinga ukwazi ukuthi ungakhetha futhi usebenzise kanjani izintambo zokunweba ze-MC4.

Isetshenziswa kanjani ikhebula le-MC4 Solar Extension?

    Izintambo ze-solar ze-MC4zifana kakhulu ngomqondo nezintambo zokunwetshwa kwamandla.Ikhebula lesandiso selanga liyafana nekhebula lokunwetshwa kwamandla, elinesiphetho sowesilisa ekugcineni kanye nesiphetho sesifazane ngakolunye uhlangothi.Ziza ngobude obuningi obuhlukene, ukusuka kumafidi ayi-8 kuye kumafidi ayi-100.Ngemva kokuxhuma amaphaneli elanga amabili ochungechungeni, uzodinga ukusebenzisa intambo yokwandisa amandla elanga ukuze ulethe amandla lapho izinto zikagesi zikhona (imvamisa ama-circuit breaker kanye nezilawuli zokushaja ilanga).Amasistimu we-Photovoltaic asebenzisa amaphaneli elanga amabili avame ukusetshenziswa kuma-RV nasezikebheni, ngakho-ke imikhondo ye-solar extension ivame ukusetshenziswa kulo lonke ibanga.

Uma usebenzisa amaphaneli elanga ophahleni, ibanga okufanele ilihambe ikhebula ngokuvamile lide kangangokuthi ukusebenzisa ikhebula lesandiso sephaneli yelanga akusasebenzi.Kulezi zimo, izintambo zokunweba zisetshenziselwa ukuxhuma ama-solar panel ebhokisini lokuhlanganisa.Lokhu kukuvumela ukuthi usebenzise izintambo ezingabizi kakhulu ngaphakathi kwamapayipi kagesi ukumboza amabanga amade ngezindleko eziphansi kakhulu kunezintambo ze-MC4.

Cabanga ukuthi ubude bekhebula obudingekayo kusukela kumaphaneli elanga amabili ukuya ezintweni zakho zikagesi ngamafidi angama-20.Okudingayo nje intambo yokunweba.Sinikeza intambo yesolar engamamitha angu-50 engcono kakhulu kulesi simo.Amaphaneli elanga amabili owaxhume ndawonye anokuhola okuhle ngesixhumi sowesilisa se-MC4 kanye nomthofu ongemuhle onesixhumi sowesifazane se-MC4.Ukuze ufinyelele idivayisi yakho phakathi kwamafithi angu-20, uzodinga izintambo ezimbili ze-PV ezingamamitha angu-20, eyodwa ngeyeduna neyesifazane.Lokhu kufezwa ngokusika umthofu wesolar ongamamitha angama-50 ngesigamu.Lokhu kuzokunikeza ukuhola okungu-25ft nesixhumi sowesilisa se-MC4 kanye nokuhola okungu-25ft nesixhumi se-MC4 sowesifazane.Lokhu kukuvumela ukuthi uxhume kuyo yomibili imikhondo yephaneli yelanga futhi kukunikeza ikhebula elanele ukuze ufike lapho uya khona.Kwesinye isikhathi ukusika ikhebula phakathi akusona isixazululo esingcono kakhulu ngaso sonke isikhathi.Ngokuya ngendawo yebhokisi lesihlanganisi se-PV, ibanga elisuka ohlangothini olulodwa lweyunithi yezinhlamvu zephaneli ye-PV ukuya ebhokisini lesihlanganisi lingase libe likhulu kunebanga ukusuka kolunye uhlangothi lwentambo yephaneli ye-PV ukuya ebhokisini lesihlanganisi.Kulokhu, uzodinga ukusika ikhebula le-PV lesandiso endaweni evumela ukuthi iziphetho ezimbili ezisikiwe zifinyelele ibhokisi lokuhlanganisa, elinegumbi elincane lokuxega.Njengoba kuboniswe ngezansi komdwebo:

Kuzinhlelo ezisebenzisa amabhokisi okuhlanganisa i-PV, umane ukhethe ubude obude ngokwanele ukuthi buqedwe ebhokisini lesihlanganisi uma usikwa.Ungakwazi ke ukukhumula insulation kusukela eziphethweni ezisikiwe futhi baqedele ukuba busbar noma isifunda breaker.
