MC4 Junction Box——Power Station “Supporting Role”

Mphamvu ya photovoltaic yomwe yangoikidwa kumene ku China yakhala yoyamba padziko lonse lapansi kwa zaka zisanu ndi chimodzi zotsatizana, ndipo ndalama zikupitilira kutsika pamene sikelo ikukulirakulira.Parity intaneti ikuyandikira pang'onopang'ono.Mu "nthawi ya phindu lochepa", kasamalidwe koyeretsedwa kwa malo opangira magetsi kwakhala mgwirizano wamakampani.Kuphatikiza pa "protagonists" monga ma photovoltaic modules ndi photovoltaic inverters, udindo waMC4 zolumikizirandi mabokosi ophatikizika a MC4 sanganyalanyazidwe.

        Mabokosi olumikizirana a MC4ndi tizigawo tating'ono m'malo opangira magetsi a photovoltaic.Mtengo wamsika wamakono uli pafupi ndi 20-25 yuan / chidutswa, chomwe chimangotenga pafupifupi 2.7% ya mtengo wa ma modules a photovoltaic, ndipo amawerengera osachepera 1% ya dongosolo lonse lamagetsi.Ndilo gawo laling'ono, koma limagwira ntchito yaikulu pachitetezo cha magetsi a photovoltaic.Ngati pali vuto ndi mtundu wazinthu, malo opangira magetsi adzakumana ndi zoopsa zazikulu.

Makampani ndi dziko lapansi, ndipo kabokosi kakang'ono kamene kalikonse ndi chitsanzo cha mafakitale a photovoltaic.Pambuyo pa ubatizo wa "nkhondo yamtengo wapatali" ndi "technical iteration", kodi makampani a bokosi la mc4 adzapita kuti mtsogolomu?

"Woyang'anira" wa Photovoltaic Modules

Bokosi lophatikizana la mc4 makamaka liri ndi ntchito ziwiri: ntchito yaikulu ndiyo kugwirizanitsa gawo la photovoltaic ndi katundu, ndi kutumiza kunja mphamvu yamagetsi yopangidwa ndi gawo la photovoltaic kudzera pa chingwe.Ntchito yowonjezera ndiyo kuteteza zigawo, zomwe zimakhala ngati chitetezo chodutsa pamene kutentha kwa malo otentha kumachitika.Choncho, bokosi la photovoltaic junction limatchedwanso chitetezo cha photovoltaic modules.

Komabe, kafukufukuyu akuwonetsa kuti pamavuto ndi ngozi zonse zapamagetsi, ngozi zomwe zimachitika chifukwa cha mabokosi ophatikizika ndi zolumikizira zimapitilira 30%, ndipo kuwonongeka kwa ma mc4 junction box diode kumapangitsa ngozi zopitilira 65% zangozi zamabokosi ndi zolumikizira.Madera omwe ali ndi vuto lalikulu.Izi zakopanso madandaulo a ogwiritsa ntchito ena pazabwino kwa bokosi lolumikizirana.

Wang Yu, wachiwiri kwa woyang'anira wamkulu wa Zhejiang Fosalang Energy Co., Ltd., yemwe wakhala akuyang'ana kwambiri makampani opanga bokosi la mc4 kwa zaka zambiri, akukhulupirira kuti ogwiritsa ntchito ambiri samvetsetsa bwino za mabokosi ophatikizika.Diode ndi gawo lofunikira la bokosi lolumikizirana.Kawirikawiri, diode ili kunja, ndipo diode idzatsegulidwa kokha pamene chigawocho chili ndi malo otentha.

Wang Yu anafotokozanso kuti pomanga ma modules a photovoltaic, selo limodzi limagwira ntchito motsatizana.Kamodzi mwa magawo a batri atatsekedwa, batire yomwe yakhudzidwa sidzagwiranso ntchito ngati gwero lamagetsi, koma idzakhala wogwiritsa ntchito mphamvu.Mabatire ena osatsekedwa adzapitilirabe kupitilira pakali pano, kupangitsa kutaya mphamvu kwamphamvu, ndipo "malo otentha" adzachitika.kuwonekera.Pamene kutentha malo zotsatira kufika pa mlingo winawake, izo kuchepetsa mphamvu linanena bungwe la zigawo zikuluzikulu ndipo ngakhale kuchititsa kuti zigawo zikuluzikulu kuti zinyamulidwe, kwambiri kuchepetsa moyo utumiki wa zigawo zikuluzikulu, ndi kuchititsa zoopsa zobisika kwa mphamvu ya mphamvu chitetezo cha siteshoni magetsi. .

Kuti mupewe vutoli, ma diode olambalala amalumikizidwa molumikizana ndi batri imodzi kapena zingapo zolumikizidwa mndandanda.Mpweya wodutsa umadutsa selo lamthunzi ndikudutsa mu diode.Pofuna kuonetsetsa kuti malo opangira magetsi a photovoltaic akupitiriza kupanga magetsi.Ngati diode ikuphwanyidwa ndikuphwanyidwa, "imapereka nsembe" yokha kuti iteteze zigawozo.

Kuchepetsa Mtengo ndi Kupititsa patsogolo Mwachangu kwa MC4 Junction Box

"Kuchepetsa ndalama ndikuwonjezera mphamvu" yakhala mutu waukulu wa makina opanga photovoltaic.Ponena za gawo laling'ono la bokosi la pv junction, chinsinsi chochepetsera mtengo komanso kukulitsa luso lagona pagawo lake lalikulu la diode.

Magulu a mabokosi ophatikizika a mc4 pamsika amatengera mitundu yosiyanasiyana, ndipo Fraser amagwiritsa ntchito ma diode monga kusiyanitsa pakati pa mitundu yamabokosi olumikizirana ndipo amadziwika nthawi zambiri.Wang Yu adalengeza kuti mankhwala a m'badwo woyamba anali axial diode, ndipo mankhwala a m'badwo wachiwiri anali diode ya SMD, yomwenso ndi mtundu wogwiritsidwa ntchito kwambiri pamsika wamakono.M'badwo wachitatu ndi diode ya module, ndipo m'badwo wachinayi ndi chinthu chanzeru.

Nthawi zambiri, pali njira ziwiri zochepetsera ndalama ndikuwonjezera kuchita bwino.Chinthu choyamba ndi kuchepetsa ndalama zoyamba.Poyerekeza m'badwo wachiwiri ndi wachitatu m'badwo wachitatu mc4 makulidwe bokosi katundu, SMD diode mphambano bokosi wapangidwa ndi diode atatu ndi 4 mapepala amkuwa, pamene module diode wapangidwa ndi gawo limodzi, amene amachepetsa ndalama zakuthupi ndi ndalama kuwotcherera pamanja.Ndi kukula kwa masikelo opangira, phindu lamtengo wapatali lazinthu zamtundu wachitatu lidzakhala lodziwika kwambiri.

Mtengowo utatha pang'onopang'ono, kuchotsa mwadala kuchepetsa mtengowo kudzawononga ntchito yazaka 25 ya malo opangira magetsi a photovoltaic.Pakadali pano, makampani ambiri ayamba kutenga njira ya "kuwonjezera mphamvu" ndikupanga zinthu zatsopano kudzera muukadaulo waukadaulo.Ngakhale mtengo woyambira ukuwonjezeka, mtengo wamagetsi ukhoza kuchepetsedwa powonjezera mphamvu yopangira mphamvu pambuyo pake.

M'badwo wachinayi wa smart mc4 junction box product ya Fusalang ndiye chida chachinsinsi cha "kuwonjezera mphamvu".Malinga ndi a Wang Yu, bokosi la smart junction box lili ndi chipangizo chamkati chanzeru chomwe chimatha kuyang'anira momwe gawo lililonse limagwirira ntchito, kukwaniritsa zofunikira pakuwunika kwa gawo, kupeza zovuta msanga, kuchepetsa kutayika kwamagetsi, ndikuwonjezera mphamvu zamagetsi ponseponse.Kuchulukitsitsa kwa mphamvu zamagetsi kumachepetsa kapena kupitilira mtengo woyambira, kuchuluka kwamphamvu kumawonekera.

Ndi kukula kosalekeza kwa luntha la photovoltaic, mabokosi ophatikizika anzeru adzakhala njira yodziwika bwino yakukula kwamtsogolo kwa mabokosi a mc4 junction.Pambuyo pa 2020, zida zamabokosi amagetsi opangira magetsi pa intaneti zidzabweretsa chitukuko.

Zotsatira Zamtundu wa Junction Box Zikuwonekera

Mpikisano wamitengo yotsika mtengo ukuwoneka ngati njira yokhayo yopititsira patsogolo magawo onse amoyo m'dziko lathu.N'chimodzimodzinso ndi mafakitale a photovoltaic.Kaya ndi ma photovoltaic modules, photovoltaic inverters kapena stents, homogeneity ya mankhwala yakhala chinthu chodziwika bwino, ndipo kugawanika kwa mabokosi a photovoltaic junction ndizosiyana.

Malinga ndi kukumbukira kwa Wang Yu, mu 2007-2008, mtengo wa bokosi la German brand mc4 junction linali pafupifupi 200 yuan, yomwe inali ulemerero wakanthawi.Ndi chifukwa cha kuyesedwa kwa magawo akulu amsika komanso ukadaulo wocheperako pomwe mabizinesi ang'onoang'ono ndi apakati aku China akusefukira kuti atenge msika.Mu 2011, panali makampani opitilira 100 pamsika, ndipo adakwera kupitilira 200 pambuyo pake.Zimaphatikizidwa ndi mpikisano wamtengo wotsika.Mu 2009, mtengo wa bokosi la photovoltaic mphambano unali pafupi 100-150 yuan.Pofika m’chaka cha 2011, mtengowo unali utatsika kufika pafupifupi ma yuan 50.Mu 2013, mtengo wa mabokosi ophatikizika adatsika mpaka 30-40 yuan.Imatsika mpaka pafupifupi 20 yuan.

Pamene mpikisano wamtengo wotsika wofanana ufika pamlingo wina, kusunthika sikungapeweke.M'zaka zingapo zapitazi, mafakitale a photovoltaic adakumana ndi kuzizira.Pambuyo pa kupulumuka kwa olimba kwambiri pamsika, makampani ena pang'onopang'ono adataya mpikisano wawo ndikuchoka.Makampani ena atsopano omwe ali ndi luso lazopangapanga, ndalama zazikulu, ndi ma tchanelo adafika pamsika ndikupeza gawo linalake.

Kwa eni ake opangira magetsi, mtengo wamabokosi ophatikizika a mc4 m'mafakitale opangira magetsi a photovoltaic ndi otsika, ndipo nthawi zambiri amagwira ntchito kuti akwaniritse kapangidwe ka malo opangira magetsi, ndipo zinthu zokhala ndi zotsimikizika zimatchuka kwambiri.Izi mosakayikira ndi mpikisano wamphamvu kwa makampani omwe akhala akugwira ntchito yopanga mabokosi a photovoltaic junction kumayambiriro koyambirira ndipo apanga sikelo ndi chizindikiro.

Zimamveka kuti pakali pano pali makampani ochepera a 100 photovoltaic junction box pamsika.Kusintha kwakukulu kwamakampani kumasokonekera, kuwonetsa kuti msika wamabokosi ophatikizika ukupita patsogolo.Pakalipano, makampani otsogola monga Renhe, Zhonghuan, ndi Fushalang atulukira mumakampani, ndipo mayendedwe odziwika bwino atulukira pang'onopang'ono.

Wang Yu akukhulupirira kuti makampani opanga bokosi la photovoltaic adzabweretsa kusinthanso m'tsogolomu, ndipo chiwerengero cha makampani a bokosi la mc4 adzakhalabe pafupifupi 50 panthawiyo.Makampaniwa agawidwa pafupifupi m'magulu awiri.Mtundu wina wamakampani uli ndi ma tchanelo abwino, ndipo mtundu wina wamakampani umadalira zinthu ndi ntchito zapamwamba kuti zitengere msika.
