Kuyambira 2016, opanga ma inverter aku China akhala otsogola pamsika wapadziko lonse wa photovoltaic inverter.Zinthu ziwiri zaukadaulo waukadaulo komanso kugwiritsa ntchito kwakukulu kwapangitsa kuchepa kwachangu kwamitengo yamalumikizidwe onse amakampani a PV, ndipo mtengo wadongosolo la PV watsika ndi 90% mzaka 10.Monga zida zapakati pa dongosolo la PV, mtengo wa inverter ya PV pa watt watsika pang'onopang'ono m'zaka 10 zapitazi, kuchoka pa yuan 1/W koyambirira mpaka pafupifupi 0.1 ~ 0.2 yuan/W mu 2021, mpaka pafupifupi 1. / 10 ya zaka 10 zapitazo.

Limbikitsani magawo

Kumayambiriro kwa chitukuko cha photovoltaic, opanga ma inverter amayang'ana kwambiri kuchepetsa mtengo wa zida, kukhathamiritsa kwamphamvu kwambiri, komanso kusinthika kwamphamvu kwamphamvu.Ndi chitukuko mosalekeza luso ndi kukweza kwa dongosolo ntchito, ndi inverter Integrated ntchito zambiri, monga chigawo PID chitetezo ndi kukonza, kusakanikirana ndi kutsatira thandizo, kuyeretsa dongosolo ndi zipangizo zina zotumphukira, kupititsa patsogolo ntchito lonse photovoltaic magetsi siteshoni. ndikuwonetsetsa kuchulukitsidwa kwa ndalama zopangira magetsi.

M'zaka khumi zapitazi, mawonekedwe ogwiritsira ntchito ma inverters akhala akuchulukirachulukira, ndipo akuyenera kukumana ndi malo osiyanasiyana ovuta komanso nyengo yoopsa, monga kutentha kwa chipululu, chinyezi chambiri komanso chifunga chamchere.Kumbali imodzi, inverter iyenera kukwaniritsa zosowa zake zowononga kutentha, kumbali ina, imayenera kupititsa patsogolo chitetezo chake kuti athe kulimbana ndi malo ovuta, omwe mosakayikira amaika patsogolo zofunikira za mapangidwe a inverter ndi zipangizo zamakono.

Pansi pa zomwe zimafunikira kwambiri pakupangira mphamvu zamagetsi komanso magwiridwe antchito kuchokera kwa opanga, makampani opanga ma photovoltaic inverter akupita patsogolo kudalirika, kutembenuka mtima komanso mtengo wotsika.

Mpikisano wowopsa wamsika wabweretsa kukweza kwaukadaulo kosalekeza.Mu 2010 kapena apo, main circuit topology ya PV inverter inali yozungulira magawo awiri, ndi kutembenuka kwamphamvu pafupifupi 97%.Masiku ano, kugwiritsa ntchito bwino kwa ma inverters opanga opanga padziko lonse lapansi kwadutsa 99%, ndipo chandamale chotsatira ndi 99.5%.Mu theka lachiwiri la 2020, ma module a photovoltaic adayambitsa ma module amphamvu kwambiri otengera 182mm ndi 210mm silicon chip size.Pasanathe theka la chaka, mabizinesi angapo monga Huawei, Sungrow Power, TBEA, Kehua Digital Energy, Hewang, Guriwat, ndi Jinlang Technology atsata mwachangu komanso motsatizana adayambitsa ma inverters apamwamba kwambiri omwe amafanana nawo.

Malinga ndi zomwe China Photovoltaic Viwanda Association, pakadali pano, msika wapakhomo wa PV inverter ukadali wotsogozedwa ndi inverter ya zingwe ndi inverter yapakati, pomwe ma inverter ena ang'onoang'ono ndi ogawidwa amakhala ochepa.Ndi kukula kwachangu kwa msika wogawidwa wa photovoltaic komanso kuwonjezeka kwa chiwerengero cha ma inverters a zingwe m'malo opangira magetsi a photovoltaic, chiwerengero chonse cha ma inverters a chingwe chawonjezeka chaka ndi chaka, kupitirira 60% mu 2020, pamene chiwerengero cha ma inverters apakati ndi ochepa. kuposa 30%.M'tsogolomu, ndikugwiritsa ntchito kwambiri ma inverters angapo m'malo akuluakulu opangira magetsi, gawo lawo la msika lidzawonjezeka.

Kutengera momwe msika wa inverter umapangidwira, mawonekedwe a opanga osiyanasiyana akuwonetsa kuti magetsi adzuwa ndi zinthu za SMA zatha, ndipo pali mabizinesi apakati ndi ma inverter angapo.Power Electronics ndi Shangneng Electric amagwiritsa ntchito ma inverters apakati.Huawei, SolarEdge, Jinlang Technology ndi Goodway zonse zimachokera pazingwe zosinthira zingwe, zomwe zida za Huawei zimakhala zosinthira zingwe zazikulu pamasiteshoni akuluakulu amagetsi ndi mafakitale ndi malonda a photovoltaic system, pomwe atatu omalizawa amakhala makamaka pamsika wapakhomo.Tsindikani, Hemai ndi Yuneng Technology amagwiritsa ntchito ma inverters ang'onoang'ono.

Pamsika wapadziko lonse lapansi, mndandanda ndi ma inverters apakati ndiye mitundu yayikulu.Ku China, gawo la msika la inverter yapakati ndi inverter yotsatsira ndi yokhazikika kuposa 90%.

M'tsogolomu, chitukuko cha inverters adzakhala osiyanasiyana.Kumbali imodzi, mitundu yogwiritsira ntchito malo opangira magetsi a photovoltaic ndi osiyanasiyana, ndipo ntchito zosiyanasiyana monga chipululu, nyanja, denga logawidwa, ndi BIPV zikuchulukirachulukira, ndi zofunika zosiyanasiyana za ma inverters.Kumbali ina, kukula kwachangu kwamagetsi amagetsi, zida ndi matekinoloje ena atsopano, komanso kuphatikiza ndi AI, deta yayikulu, intaneti ndi matekinoloje ena, zimayendetsanso kupita patsogolo kopitilira muyeso kwa inverter.Inverter ikupita patsogolo pakuchita bwino kwambiri, kuchuluka kwamphamvu kwamagetsi, magetsi okwera a DC, anzeru kwambiri, otetezeka, kusinthika kwamphamvu kwachilengedwe, komanso kugwira ntchito mwaubwenzi ndi kukonza.

Kuphatikiza apo, ndikugwiritsa ntchito kwakukulu kwa mphamvu zongowonjezwdwa padziko lapansi, kuchuluka kwa kulowa kwa PV kukuchulukirachulukira, ndipo inverter imayenera kukhala ndi mphamvu yamphamvu yothandizira grid kuti ikwaniritse zofunikira zogwirira ntchito mokhazikika komanso kuyankha mwachangu kwa gridi yofooka yapano.Kuphatikizika kwa kusungirako kwa kuwala, kusungirako kuwala ndi kuphatikizika kolipiritsa, kupanga photovoltaic haidrojeni ndi zina zatsopano ndi zophatikizika zogwiritsa ntchito pang'onopang'ono zidzakhala njira yofunikira, ndipo inverter idzalowetsa malo okulirapo.
