Agasanduku ka MC4 —— Sitasiyo Yamashanyarazi “Uruhare Rufasha”

Ubushinwa bwashyizwemo ingufu za Photovoltaque bwashyizwe ku mwanya wa mbere ku isi mu myaka itandatu ikurikiranye, kandi ibiciro byakomeje kugabanuka uko igipimo gikomeza kwiyongera.Parite igera kuri enterineti iragenda yegereza.Mu "gihe gito cy'inyungu", imicungire inoze ya sitasiyo y'amashanyarazi yabaye ubwumvikane bw'inganda.Usibye "ba nyirarureshwa" nka moderi ya Photovoltaque na inverters ya fotovoltaque, uruhare rwaMC4 ihuzana MC4 isanduku ihuza ntishobora kwirengagizwa.

        Agasanduku ka MC4ni ibice bito mumashanyarazi.Igiciro kiriho ubu ni hafi 20-25 yuan / igice, kikaba kibarirwa hafi 2.7% yikiguzi cyamafoto yerekana amashanyarazi, kandi kikaba kiri munsi ya 1% ya sisitemu yose yamashanyarazi.Nibintu bito, ariko bigira uruhare runini mumutekano wamashanyarazi.Niba hari ikibazo kijyanye nubwiza bwibicuruzwa, sitasiyo yamashanyarazi izahura ningaruka nini.

Inganda nisi, kandi agasanduku gahuza agasanduku nako karanga inganda zifotora.Nyuma yo kubatizwa kw "intambara yibiciro" na "tekinike ya tekinike", inganda za mc4 zihuza inganda zizajya he?

“Umurinzi” wa Moderi ya Photovoltaque

Agasanduku ka mc4 gahuza cyane cyane gafite imirimo ibiri: umurimo wibanze ni uguhuza moderi ya fotovoltaque nu mutwaro, no kohereza ingufu z'amashanyarazi zakozwe na module ya fotora ikoresheje umugozi.Igikorwa cyinyongera ni ukurinda ibice, bikora nko kurinda bypass mugihe ingaruka zishyushye zibaye.Kubwibyo, agasanduku gafotora ifotora nayo yitwa umurinzi wa moderi yifoto.

Nyamara, ubushakashatsi bwerekana ko mu makosa yose y’amashanyarazi n’impanuka, impanuka zatewe nagasanduku gahuza hamwe n’umuhuza zagize hejuru ya 30%, naho gusenyuka kwa mc4 agasanduku ka diode byari hejuru ya 65% by’isanduku ihuza n’impanuka.Uturere dufite ibibazo byinshi byamakosa.Ibi kandi byakuruye bamwe mubakoresha ibibazo bijyanye nubwiza bwibisanduku.

Wang Yu, umuyobozi mukuru wungirije mukuru wa Zhejiang Fosalang Energy Co., Ltd., wibanze ku nganda zikora amasanduku ya mc4 mu myaka myinshi, yizera ko abakoresha benshi bafite ukutumvikana ku dusanduku duhuza.Diode nigice cyingenzi cyisanduku ihuza.Mubisanzwe, diode iri muri reta, kandi diode izafungurwa gusa mugihe ibice bifite ahantu hashyushye.

Wang Yu yakomeje asobanura ko mu iyubakwa ry’amafoto y’amashanyarazi, selile imwe ikora mu ruhererekane.Iyo kimwe mu bice bya batiri bimaze guhagarikwa, bateri yibasiwe ntizongera gukora nkisoko yingufu, ahubwo izahinduka abakoresha ingufu.Izindi bateri zidafunzwe zizakomeza kunyura muri zo, bitera gutakaza ingufu nyinshi, kandi "ahantu hashyushye" hazabaho.Kugaragara.Iyo ingaruka zishyushye zigeze kurwego runaka, bizagabanya ingufu ziva mubice ndetse binatera ibice guseswa, bigabanye cyane ubuzima bwa serivisi bwibigize, kandi biteza akaga kihishe kumutekano wamashanyarazi kumashanyarazi. .

Kugira ngo wirinde iki kibazo, diode ya bypass ihujwe na bateri imwe cyangwa nyinshi zahujwe murukurikirane.Inzira ya bypass izenguruka selile igicucu kandi inyuze muri diode.Kugirango rero tumenye neza ko amashanyarazi yamashanyarazi akomeje gutanga amashanyarazi.Niba diode irenze kandi igacika, "yigomwa" ubwayo kugirango irinde ibice.

Kugabanya Ibiciro no Kongera imbaraga za MC4 Agasanduku

"Kugabanya ibiciro no kongera imikorere" byahindutse insanganyamatsiko nyamukuru yinganda zifotora.Kubijyanye nigice gito cya pv ihuza agasanduku, urufunguzo rwo kugabanya ibiciro no kongera imikorere biri murwego rwibanze-diode.

Itondekanya ryibisanduku bya mc4 kumasoko bishingiye kubwoko butandukanye, kandi Fraser ikoresha diode nkitandukaniro riri hagati yubwoko bwibisanduku kandi bizwi muri rusange.Wang Yu yerekanye ko igisekuru cya mbere cyari diode ya axial, naho igisekuru cya kabiri cyari diode ya SMD, nacyo kikaba ari ubwoko bukoreshwa cyane ku isoko ryubu.Igisekuru cya gatatu ni module diode, kandi igisekuru cya kane nigicuruzwa cyubwenge.

Muri rusange, hari intambwe ebyiri zo kugabanya ibiciro no kongera imikorere.Intambwe yambere nukugabanya ishoramari ryambere.Ugereranije igisekuru cya kabiri nigisekuru cya gatatu mc4 yisanduku yibicuruzwa, agasanduku ka SMD diode kagizwe na diode eshatu nimpapuro 4 zumuringa, mugihe module diode igizwe na module imwe, igabanya ibiciro byibikoresho hamwe nigiciro cyo gusudira.Hamwe no kwagura igipimo cyibikorwa, inyungu yibiciro byibisekuru bya gatatu bizagenda bigaragara.

Nyuma yuko igiciro kimaze kugabanuka, gukuramo nkana kugabanya ikiguzi bizangiza ibikorwa byimyaka 25 yumuriro wamashanyarazi.Muri iki gihe, ibigo byinshi bitangiye gufata inzira yo "kongera imikorere" no guteza imbere ibicuruzwa bishya binyuze mu guhanga ikoranabuhanga.Nubwo igiciro cyambere cyiyongereye, ikiguzi cyamashanyarazi kirashobora kugabanuka mukongera ingufu zamashanyarazi mubyiciro bizakurikiraho.

Igisekuru cya kane cyubwenge mc4 ihuza agasanduku k'ibicuruzwa bya Fusalang nintwaro y'ibanga yo "kongera imikorere".Nk’uko Wang Yu abitangaza ngo ibicuruzwa byifashishwa mu isanduku bifite ubwenge bifite chip y'imbere ishobora kugenzura imikorere ya buri kintu, ikuzuza ibisabwa mu rwego rwo kugenzura urwego, gushakisha ibibazo hakiri kare, kugabanya igihombo cy’amashanyarazi, no kongera amashanyarazi muri rusange.Iyo amashanyarazi yiyongereye yongeweho cyangwa arenze ikiguzi cyambere, ubukungu bwikigereranyo buzagaragara.

Hamwe niterambere rihoraho ryubwenge bwa Photovoltaque, udusanduku twubwenge twububiko bizaba inzira rusange yiterambere ryigihe kizaza cya mc4.Nyuma ya 2020, ibikoresho bya enterineti bishingiye ku mbaraga za interineti ihuza ibicuruzwa bizatangiza iterambere.

Ingaruka yibiranga agasanduku gahuza kugaragara

Amarushanwa ahendutse ku bahuje ibitsina asa nkinzira yonyine yiterambere ryinzego zose zigihugu cyacu.Ni nako bimeze no mu nganda zifotora.Yaba modules ya fotokoltaque, inverteri ya fotora cyangwa stent, ibicuruzwa byahuje ibitsina byahindutse ibintu bisanzwe, kandi kugabana udusanduku twa fotokoltaque nabyo ntibisanzwe.

Dukurikije ibyo Wang Yu yibuka, mu 2007-2008, igiciro cy’isanduku yo mu Budage ya mc4 ihuza agasanduku kari hafi 200, cyari icyubahiro gito.Ni ukubera rwose ibishuko by'ibice binini by'isoko hamwe n'ikoranabuhanga ritoya niho imishinga mito n'iciriritse yo mu Bushinwa irihutira gufata isoko.Muri 2011, ku isoko hari amasosiyete arenga 100, kandi yageze ku barenga 200 nyuma.Iherekejwe n'amarushanwa make.Muri 2009, igiciro cyibisanduku bifotora bifotora byari hafi 100-150.Kugeza mu 2011, igiciro cyari cyaragabanutse kugera ku mafaranga 50.Muri 2013, igiciro cyibisanduku byahujwe cyamanutse kugera kuri 30-40.Iramanuka igera kuri 20.

Iyo abahuje ibitsina bahendutse bageze kurwego runaka, guhindagurika byanze bikunze.Mu myaka mike ishize, inganda zifotora zahuye nubukonje bukabije.Nyuma yo kubaho kw'ibikwiye ku isoko, ibigo bimwe na bimwe byatakaje buhoro buhoro guhangana kandi biragenda.Ibigo bimwe bishya bifite ikoranabuhanga, igishoro, hamwe numuyoboro byinjiye mumasoko kandi byunguka umugabane runaka.

Kubafite amashanyarazi, igiciro cyibisanduku bya mc4 mumashanyarazi yamashanyarazi ni make, kandi mubisanzwe bikora kugirango bihuze nigishushanyo mbonera cy’amashanyarazi, kandi ibicuruzwa bifite ubuziranenge byemewe birakunzwe cyane.Nta gushidikanya ko aribwo buryo bukomeye bwo guhatanira amasosiyete yagize uruhare mu gukora udusanduku tw’amafoto ya fotora mu cyiciro cya mbere kandi byagize ingaruka nziza.

Byumvikane ko kuri ubu ku isoko hari ibigo bitarenga 100 bifotora bifata amafoto.Umuhengeri munini winganda zirahindagurika, byerekana ko inganda zihuza inganda zitera imbere muburyo bwiza.Kugeza ubu, ibigo bikomeye nka Renhe, Zhonghuan, na Fushalang byagaragaye mu nganda, kandi uburyo bwo kwamamaza bwagiye bugaragara buhoro buhoro.

Wang Yu yizera ko inganda zifotora zifotora zizatangira kuvugururwa mu bihe biri imbere, kandi umubare w’ibigo by’amasanduku ya mc4 bizaguma kuri 50 icyo gihe.Izi sosiyete zigabanijwemo ibice bibiri.Ubwoko bumwe bwisosiyete bufite imiyoboro myiza, naho ubundi bwoko bwisosiyete bushingira kubicuruzwa na serivise nziza zo mu rwego rwo gufata isoko.
