MC4 Junction Box——Power Station “Kōkoʻo Hana”

Ua pae mua ka mana photovoltaic hou o Kina ma ka honua no ʻeono mau makahiki, a ke hoʻomau nei ka hāʻule ʻana o nā kumukūʻai i ka hoʻonui ʻana o ka unahi.Ke hoʻokokoke mālie nei ka ʻike pūnaewele ʻo Parity.I ka "manawa haʻahaʻa haʻahaʻa", ua lilo ka hoʻokele hoʻomaʻemaʻe ʻana i nā kikowaena mana i ka ʻae o ka ʻoihana.Ma waho aʻe o nā "protagonists" e like me nā modula photovoltaic a me nā photovoltaic inverters, ke kuleana oNā mea hoʻohui MC4ʻAʻole hiki ke nānā ʻia nā pahu hui MC4.

        Nā pahu hui MC4he mau ʻāpana liʻiliʻi i nā kikowaena mana photovoltaic.ʻO ke kumukūʻai o ka mākeke o kēia manawa e pili ana i 20-25 yuan / ʻāpana, ʻo ia wale nō ka helu no ka 2.7% o ke kumukūʻai o nā modula photovoltaic, a ʻoi aku ka liʻiliʻi ma mua o 1% o ka ʻōnaehana mana holoʻokoʻa.He mea liʻiliʻi ia, akā he kuleana nui ia i ka palekana o nā mea kanu mana photovoltaic.Inā he pilikia me ka maikaʻi o ka huahana, e kū ana ka mana mana i nā pilikia nui.

ʻO kahi ʻoihana he honua, a ʻo kahi pahu hui liʻiliʻi ka mea hoʻohālike o ka ʻoihana photovoltaic.Ma hope o ka bapetizo ʻana o ka "kaua kūʻai" a me ka "ʻike loea", ma hea kahi e hele ai ka ʻoihana pahu pahu mc4 i ka wā e hiki mai ana?

ʻO ka "Kākua" o nā Module Photovoltaic

ʻO ka pahu pahu mc4 ka nui o nā hana ʻelua: ʻo ka hana kumu e hoʻopili i ka module photovoltaic a me ka ukana, a e hoʻokuʻu aku i ka ikehu uila i hana ʻia e ka module photovoltaic ma o ke kaula.ʻO ka hana hou aʻe ka pale ʻana i nā ʻāpana, e hana ana ma ke ʻano he pale bypass ke hiki mai ka hopena wela.No laila, ua kapa ʻia ka pahu pahu kiʻi kiʻi kiʻi i ke kiaʻi o nā modula photovoltaic.

Eia nō naʻe, ke hōʻike nei ka noiʻi i nā hewa a me nā ulia pōpilikia āpau, ʻoi aku ka nui o nā ulia i hana ʻia e nā pahu hui a me nā mea hoʻohui i ʻoi aku ma mua o 30%, a ʻo ka haki ʻana o nā diodes pahu pahu mc4 i ʻoi aku ma mua o 65% o nā pahu hui a me nā ulia hoʻohui.Nā wahi me ka nui o nā hewa.Ua hoʻopiʻi pū kekahi mau mea hoʻohana e pili ana i ka maikaʻi o ka pahu hui.

Manaʻo ʻo Wang Yu, ka hope manakia nui o Zhejiang Fosalang Energy Co., Ltd., ka mea i kālele i ka ʻoihana pahu pahu mc4 no nā makahiki he nui, ke manaʻoʻiʻo nei he kuhihewa ka hapa nui o nā mea hoʻohana e pili ana i nā pahu hui.He mea nui ka diode o ka pahu hui.ʻO ka maʻamau, aia ka diode i ke kūlana paʻa, a e hoʻāla ʻia ka diode i ka wā e loaʻa ai kahi wahi wela.

Ua wehewehe hou aku ʻo Wang Yu i ke kūkulu ʻana i nā modula photovoltaic, hoʻokahi kelepona e hana i ka moʻo.Ke paʻa ʻia kekahi o nā ʻāpana pākaukau, ʻaʻole e hana hou ka pākaukau i hoʻopili ʻia ma ke ʻano he kumu mana, akā e lilo ia i mea kūʻai ikehu.E hoʻomau ka hele ʻana o nā pākahi ʻē aʻe i hoʻopaʻa ʻole ʻia ma o lākou, e hoʻemi nui ana i ka ikehu, a hiki mai nā "wahi wela".puka mai.Ke piʻi ka hopena wela i kahi pae, e hōʻemi ia i ka mana o nā ʻāpana a hiki ke hoʻopau ʻia nā ʻāpana, e hōʻemi nui i ke ola lawelawe o nā ʻāpana, a e hoʻopilikia i nā pilikia huna i ka palekana o ka mana o ka mana. .

No ka pale ʻana i kēia pilikia, hoʻopili ʻia nā diodes bypass i hoʻokahi a i ʻole kekahi mau pihi i hoʻopili ʻia ma ke ʻano.E kaalo ana ke au i ke keena malu a hele ma ka diode.I mea e hōʻoia ai ka hoʻomau ʻana o ka mana photovoltaic i ka uila.Inā hoʻopau a wāwahi ʻia ka diode, "ʻālana" ʻo ia iā ia iho e pale i nā ʻāpana.

Hoʻemi i ke kumukūʻai a me ka hoʻonui ʻana i ka pono o nā pahu hui MC4

"E ho'ēmi i nā kumukūʻai a hoʻonui i ka maikaʻi" ua lilo i kumuhana nui o ke kaulahaoʻoihana photovoltaic.E pili ana i ka hapa liʻiliʻi o ka pahu hui pv, ʻo ke kī i ka hōʻemi ʻana i ke kumukūʻai a me ka hoʻonui ʻana i ka pono aia i loko o kāna mea nui-diode.

Hoʻokumu ʻia ka hoʻokaʻawale ʻana o nā pahu hui mc4 ma ka mākeke ma nā ʻano like ʻole, a hoʻohana ʻo Fraser i nā diodes ma ke ʻano he ʻokoʻa ma waena o nā ʻano pahu hui a ʻike ʻia.Ua hoʻolauna ʻo Wang Yu i ka huahana mua o ka hanauna he axial diode, a ʻo ka huahana lua o ka hanauna he SMD diode, ʻo ia hoʻi ke ʻano i hoʻohana nui ʻia i ka mākeke o kēia manawa.ʻO ke kolu o ka hanauna he diode module, a ʻo ka hā o ka hanauna he huahana naʻauao.

ʻO ka mea maʻamau, ʻelua mau ʻanuʻu e hōʻemi i nā kumukūʻai a hoʻonui i ka pono.ʻO ka hana mua e hoʻemi i ka hoʻokomo mua.Ke hoʻohālikelike nei i ka lua a me ke kolu o ka hanauna mc4 junction box huahana, ka SMD diode junction box ua haku ʻia me ʻekolu diodes a me 4 mau ʻāpana keleawe, ʻoiai ka module diode i haku ʻia i hoʻokahi module, e hōʻemi ana i nā kumukūʻai waiwai a me nā kumukūʻai kuʻi lima.Me ka hoʻonui ʻana i ka pālākiō hana, ʻoi aku ka maikaʻi o ke kumukūʻai o nā huahana ʻekolu o nā hanauna.

Ma hope o ka emi iki ʻana o ke kumukūʻai, ʻo ka unuhi ʻana i ka manaʻo e hōʻemi i ke kumukūʻai e hōʻino i ka hana 25-makahiki o ka hale mana photovoltaic.I kēia manawa, hoʻomaka ka nui o nā ʻoihana e hele i ke ala o ka "hoʻonui ʻana i ka pono" a hoʻomohala i nā huahana hou ma o ka ʻenehana ʻenehana.ʻOiai ua hoʻonui ʻia ke kumukūʻai mua, hiki ke hoʻemi ʻia ke kumukūʻai o ka uila ma o ka hoʻonui ʻana i ka mana hana mana ma ka pae hope.

ʻO ka ʻehā o ka hanauna akamai mc4 junction box huahana o Fusalang ka mea huna o ka "hoʻonui i ka pono".Wahi a Wang Yu, loaʻa i ka pahu pahu junction akamai kahi puʻupuʻu akamai i loko e hiki ke nānā i ke kūlana hana o kēlā me kēia ʻāpana, e hoʻokō i nā koi o ka nānā ʻana i nā ʻāpana-level, e ʻimi koke i nā pilikia, e hōʻemi i ka nalowale o ka mana, a hoʻonui i ka hana mana holoʻokoʻa.Ke hoʻonui a ʻoi aku paha ka nui o ka mana o ke kumu kūʻai mua, e ʻike ʻia ka ʻoihana waiwai.

Me ka hoʻomau mau ʻana o ka naʻauao photovoltaic, ʻo nā pahu junction akamai ke ʻano maʻamau o ka hoʻomohala ʻana o nā pahu hui mc4.Ma hope o 2020, e hoʻomaka ka hoʻomohala ʻana o nā huahana pahu pahu pahu pūnaewele puni honua.

ʻIke ʻia ka hopena inoa o ka pahu Junction

ʻO ka hoʻokūkū kūʻai haʻahaʻa like ʻole me he mea lā ʻo ia wale nō ke ala no ka hoʻomohala ʻana i nā ʻano like ʻole o ke ola o ko mākou ʻāina.Pēlā nō ia i ka ʻoihana photovoltaic.Inā he photovoltaic modules, photovoltaic inverters a stents paha, ua lilo ka homogeneity huahana i mea maʻamau, a ʻo ka hoʻokaʻawale ʻana o nā pahu hui photovoltaic ʻaʻole he ʻokoʻa.

Wahi a Wang Yu hoʻomanaʻo, i ka makahiki 2007-2008, ʻo ke kumukūʻai o ka pahu junction brand German mc4 ma kahi o 200 yuan, ʻo ia ka nani o ka manawa.ʻO ia ma muli o ka hoʻowalewale o nā māhele mākeke nui a me nā paepae ʻenehana haʻahaʻa e hoʻopiʻi nei nā ʻoihana liʻiliʻi a me nā liʻiliʻi Kina e hopu i ka mākeke.Ma 2011, ua ʻoi aku ma mua o 100 mau hui ma ka mākeke, a ua piʻi aʻe ma mua o 200 ma hope.Hoʻopili pū ʻia me ka hoʻokūkū kumu kūʻai haʻahaʻa.I ka makahiki 2009, he 100-150 yuan ke kumu kūʻai o nā pahu hoʻokuʻi photovoltaic.I ka makahiki 2011, ua emi ke kumu kūʻai ma kahi o 50 yuan.I ka makahiki 2013, ua hāʻule ke kumukūʻai o nā pahu hui i 30-40 yuan.E hāʻule ana ma kahi o 20 yuan.

Ke hiki i ka hoʻokūkū kumu kūʻai haʻahaʻa homogeneous i kekahi pae, ʻaʻole hiki ke shuffling.I nā makahiki i hala iho nei, ua hālāwai ka ʻoihana photovoltaic i kahi nalu anu.Ma hope o ke ola ʻana o ka poʻe kūpono i ka mākeke, ua nalowale kekahi mau ʻoihana i kā lākou hoʻokūkū a haʻalele.ʻO kekahi mau hui hou me ka ʻenehana, kapikala, a me nā alahele i ʻoki ʻia i loko o ka mākeke a loaʻa i kahi ʻāpana.

No nā mea nona ka mana, he haʻahaʻa loa ke kumukūʻai o nā pahu junction mc4 i nā mea kanu photovoltaic, a ʻoi aku ka kaulana o nā huahana me ka maikaʻi.He mea kānalua kēia he hoʻokūkū ikaika no nā ʻoihana i hana i ka hana ʻana i nā pahu junction photovoltaic i ka wā mua a ua hoʻokumu i kahi pālākiō a me ka hopena brand.

Ua hoʻomaopopo ʻia aia i kēia manawa aia ma lalo o 100 mau hui pahu pahu pahu kiʻi kiʻi kiʻi ma ka mākeke.ʻO ka nalu nui o kaʻoihana shuffle, e hōʻike ana i ka uluʻana o kaʻoihana pahu hui i kahi ala kūpono.I kēia manawa, ua puka mai nā hui alakaʻi e like me Renhe, Zhonghuan, a me Fushalang i ka ʻoihana, a ua puka mālie ke ʻano o ka branding.

Manaʻo ʻo Wang Yu e hoʻomaka ana ka ʻoihana pahu pahu kiʻi kiʻi kiʻi i kahi reshuffle i ka wā e hiki mai ana, a e mau ana ka nui o nā hui pahu hui mc4 ma kahi o 50 ma ia manawa.Hoʻokaʻawale ʻia kēia mau ʻoihana i ʻelua mau ʻāpana.ʻO kekahi ʻano ʻoihana he ala maikaʻi, a ʻo ke ʻano ʻoihana ʻē aʻe e hilinaʻi nei i nā huahana kiʻekiʻe a me nā lawelawe e noho ai i ka mākeke.
