MC4 Junction Bhokisi——Siteshi Yemagetsi “Kutsigira Basa”

China ichangobva kuisirwa photovoltaic simba yakagara pekutanga munyika kwemakore matanhatu akateedzana, uye mitengo yakaramba ichidonha sezvo chiyero chiri kuramba chichiwedzera.Parity Indaneti inosvika zvishoma nezvishoma.Mu "nguva yakaderera purofiti", manejimendi akakwenenzverwa ezviteshi zvemagetsi kwave kubvumirana kweindasitiri.Mukuwedzera kune "protagonists" senge photovoltaic modules uye photovoltaic inverters, basa reMC4 zvibatanidzauye MC4 junction mabhokisi haagone kufuratirwa.

        MC4 junction mabhokisizvikamu zviduku mu photovoltaic power stations.Ikozvino mutengo wemusika unosvika 20-25 yuan / chidimbu, iyo inongoverengera nezve 2.7% yemutengo we photovoltaic modules, uye inoverengera isingasviki 1% yesimba rese rechiteshi system.Icho chikamu chiduku chakadaro, asi chinoita basa guru mukuchengetedzwa kwemagetsi e photovoltaic.Kana paine dambudziko nemhando yechigadzirwa, chiteshi chemagetsi chinotarisana nenjodzi huru.

Indasitiri inyika, uye bhokisi diki rekusangana ndiro zvakare epitome yephotovoltaic indasitiri.Mushure mekubhabhatidzwa kwe "price war" uye "technical iteration", iyo mc4 junction box industry ichaenda kupi mune ramangwana?

Iyo "Bodyguard" ye Photovoltaic Modules

Iyo mc4 junction box inonyanya kuita mabasa maviri: basa rekutanga nderekubatanidza iyo photovoltaic module uye mutoro, uye kutumira kunze simba remagetsi rinogadzirwa ne photovoltaic module kuburikidza netambo.Basa rekuwedzera nderokudzivirira zvikamu, izvo zvinoita sekudzivirira kwekudzivirira kana kupisa kwemavara kunoitika.Nokudaro, iyo photovoltaic junction box inonziwo murindi we photovoltaic modules.

Nekudaro, ongororo iyi inoratidza kuti mune ese emagetsi chiteshi kukanganisa uye tsaona, tsaona dzinokonzerwa nejunction mabhokisi uye zvibatanidza zvinodarika 30%, uye kuparara kwemc4 junction box diodes inodarika 65% yejojo ​​bhokisi uye tsaona yekubatanidza.Nzvimbo dzine huwandu hwakawanda hwekukanganisa.Izvi zvakwezvawo zvichemo zvevamwe vashandisi nezve kunaka kweiyo junction bhokisi.

Wang Yu, mutevedzeri mukuru maneja weZhejiang Fosalang Energy Co., Ltd., uyo akatarisana nemc4 junction box indasitiri kwemakore akawanda, anotenda kuti vashandisi vazhinji vane kusanzwisisana pamusoro pemabhokisi ejunction.Iyo diode chikamu chakakosha chebhokisi rekusangana.Kazhinji, iyo diode iri kunze kwenyika, uye diode ichavhurwa chete kana chikamu chine nzvimbo inopisa.

Wang Yu akatsanangura zvakare kuti pakuvakwa kwe photovoltaic modules, imwe sero inoshanda mumutsara.Kana imwe yebhatiri zvidimbu zvavharwa, bhatiri rakakanganiswa harichashanda sesimba sosi, asi richava mutengi wesimba.Mamwe mabhatiri asina kuvharwa acharamba achipfuura ikozvino kuburikidza navo, zvichikonzera kurasikirwa kwesimba guru, uye "nzvimbo dzinopisa" zvichaitika.oneka.Kana iyo inopisa nzvimbo inosvika pane imwe nhanho, inoderedza kubuda kwesimba rezvikamu uye kutokonzera kuti zvikamu zviraswe, zvichideredza zvakanyanya hupenyu hwesevhisi yezvikamu, uye zvichikonzera njodzi dzakavanzwa kukuchengetedzwa kwemagetsi echiteshi chemagetsi. .

Kuti udzivise dambudziko iri, bypass diodes yakabatanidzwa mukufanana kune imwe kana akati wandei mabhatiri akabatana munhevedzano.Iyo bypass yazvino ichapfuura sero ine shaded uye inopfuura nepakati diode.Kuti uve nechokwadi chekuti photovoltaic power station inoramba ichigadzira magetsi.Kana iyo diode yakanyanyisa uye yakaputsika, "inozvipira" pachayo kuchengetedza zvikamu.

Kuderedza Mutengo uye Kubudirira Kwekusimudzira kweMC4 Junction Mabhokisi

"Kuderedza mari uye kuwedzera kushanda" kwakava musoro mukuru we photovoltaic industry chain.Nezve chikamu chidiki cheiyo pv junction bhokisi chine chekuita, kiyi yekudzikisa mutengo uye kuwedzera kushanda zvakanaka iri muchikamu chayo-diode.

Kurongeka kwemc4 junction mabhokisi pamusika kwakavakirwa pamhando dzakasiyana, uye Fraser inoshandisa diode semusiyano pakati pemhando dzebhokisi rejunction uye inowanzo zivikanwa.Wang Yu akazivisa kuti chigadzirwa chechizvarwa chekutanga chaive axial diode, uye yechipiri-chizvarwa chigadzirwa chaive SMD diode, inova ndiyo inonyanya kushandiswa mhando mumusika wazvino.Chizvarwa chechitatu imodule diode, uye chizvarwa chechina chigadzirwa chakangwara.

Kazhinji kutaura, kune matanho maviri ekudzikisa mari uye kuwedzera kushanda.Danho rokutanga nderokuderedza mari yekutanga.Kuenzanisa chizvarwa chechipiri uye chechitatu-chizvarwa mc4 junction bhokisi zvigadzirwa, SMD diode junction bhokisi rinoumbwa ne diode matatu uye 4 mapepa emhangura, nepo module diode inoumbwa ne module imwe chete, iyo inoderedza mari yezvinhu uye manual welding mari.Nekuwedzera kwechiyero chekugadzira, mukana wemutengo wezvigadzirwa zvechizvarwa chechitatu uchave wakakurumbira.

Mushure mokunge mari yacho yapera zvishoma nezvishoma, kubvisa nemaune kuderedza mutengo kunokonzera kukanganisa kushanda kwegore re 25 ye photovoltaic power station.Panguva ino, makambani akawanda ari kutanga kutora nzira ye "kuwedzera kushanda zvakanaka" uye kugadzira zvigadzirwa zvitsva kuburikidza nehunyanzvi hwekuita.Kunyangwe mutengo wekutanga uchiwedzerwa, mutengo wemagetsi unogona kuderedzwa nekuwedzera simba rekugadzira simba mune inotevera nhanho.

Yechina-chizvarwa smart mc4 junction bhokisi chigadzirwa cheFusalang ndicho chombo chakavanzika che "kuwedzera kugona".Sekureva kwaWang Yu, iyo smart junction bhokisi chigadzirwa ine yemukati smart chip iyo inogona kutarisa mamiriro ekushanda kwechikamu chimwe nechimwe, kusangana nezvinodiwa zvechikamu-chikamu chekutarisa, kutsvaga matambudziko nekukurumidza, kuderedza kurasikirwa kwekugadzira magetsi, uye kuwedzera kugadzirwa kwemagetsi zvachose.Kana iyo yakawedzera kugadzirwa kwemagetsi inodzikisira kana kutopfuura mutengo wekutanga, hupfumi hwekuyera huchabuda pachena.

Nekuenderera mberi kwekuvandudza kwe photovoltaic intelligence, smart junction mabhokisi ichave yakajairika maitiro eiyo ramangwana kuvandudzwa kwemc4 junction mabhokisi.Mushure me2020, smart grid-yakavakirwa simba Internet junction bhokisi zvigadzirwa zvinounza budiriro.

Iyo Brand Effect yeJunction Bhokisi Inooneka

Homogeneous yakaderera-mutengo kukwikwidza kunoratidzika seyo chete nzira yekuvandudza kwese kwese kwehupenyu munyika yedu.Izvo zvakafanana ndezvechokwadi mune photovoltaic industry.Zvingave zviri photovoltaic modules, photovoltaic inverters kana stents, chigadzirwa chehomogeneity chave chiitiko chinowanzoitika, uye kupatsanurwa kwe photovoltaic junction mabhokisi hazvisi izvo.

Maererano nekuyeuka kwaWang Yu, muna 2007-2008, mutengo weGermany brand mc4 junction box yaiva inenge 200 yuan, iyo yaiva kubwinya kwechinguva.Izvo chaizvo nekuda kwekuyedzwa kwezvikamu zvakakura zvemusika uye yakaderera tekinoroji zvikumbaridzo izvo maChinese madiki uye epakati mabhizinesi mabhizinesi ari kutatarika kutora musika.Muna 2011, pakanga paine makambani anopfuura zana pamusika, uye yakawedzera kupfuura mazana maviri zvakazotevera.Inoperekedzwa nemakwikwi emutengo wakaderera.Muna 2009, mutengo we photovoltaic junction mabhokisi wakanga uri pamusoro pe100-150 yuan.Pakazosvika gore ra2011, mutengo wainge wadzika kusvika pa50 yuan.Muna 2013, mutengo wemabhokisi ekusangana wakawira ku30-40 yuan.Inodonha kusvika ku20 yuan.

Kana makwikwi emitengo yakaderera asvika pane imwe nhanho, kudhumhana hakudzivisiki.Mumakore mashomanana apfuura, photovoltaic industry yakasangana nechando chinotonhora.Mushure mekurarama kwevakasimba kwazvo pamusika, mamwe makambani akarasikirwa zvishoma nezvishoma nemakwikwi uye akasiya.Mamwe makambani matsva ane tekinoroji, capital, uye machanera akapinda mumusika uye akawana imwe mugove.

Kune varidzi vezviteshi zvemagetsi, mutengo wemc4 junction mabhokisi mune photovoltaic magetsi zvidyarwa zvakaderera, uye kazhinji zvinoshanda kusangana nedhizaini yechiteshi chemagetsi, uye zvigadzirwa zvine mhando yakavimbiswa zvinonyanya kufarirwa.Uku pasina mubvunzo kukwikwidza kwakasimba kwemakambani akave akabatanidzwa mukugadzirwa kwe photovoltaic junction mabhokisi mukutanga kwekutanga uye akagadzira chiyero uye brand effect.

Zvinonzwisisika kuti pane ikozvino pasi pe100 photovoltaic junction box makambani pamusika.Iwo mafungu makuru eindastiri anozununguka, achiratidza kuti iyo junction box indasitiri iri kusimukira munzira ine musoro.Parizvino, makambani anotungamira akadai saRenhe, Zhonghuan, uye Fushalang akabuda muindastiri, uye maitiro ekumaka akatanga kubuda zvishoma nezvishoma.

Wang Yu anotenda kuti photovoltaic junction box industry ichaunza reshuffle mune ramangwana, uye nhamba yemc4 junction box makambani acharamba ari anenge makumi mashanu panguva iyoyo.Makambani aya akakamurwa kuita mapoka maviri.Imwe mhando yekambani ine nzira dzakanaka, uye imwe mhando yekambani inotsamira pane zvemhando yepamusoro zvigadzirwa nemasevhisi kuti atore musika.
