Bitewe nuburyo butandukanye bwinyubako, byanze bikunze bizaganisha ku gutandukana kwizuba ryizuba.Kugirango turusheho guhindura imikorere yingufu zizuba mugihe uzirikana isura nziza yinyubako, ibi bisaba gutandukanya inverteri zacu kugirango tugere kuburyo bwiza bwingufu zizuba.Guhindura.Uburyo bukoreshwa cyane nizuba ryizuba kwisi kwisi ni: guhinduranya hagati, guhuza imirongo, imirongo myinshi ihinduranya hamwe nibice bigize inverter.Noneho tuzasesengura porogaramu za inverter nyinshi.

Inverteri yo hagati ikoreshwa muri sisitemu ifite amashanyarazi manini (》 10kW).Imirongo myinshi ibangikanye ifoto yumurongo ihujwe na DC yinjiza imwe ihuriweho na inverter.Mubisanzwe, ibyiciro bitatu IGBT modules ikoreshwa mumashanyarazi menshi.Imbaraga zo hasi zikoresha tristoriste yumurima hamwe na DSP ihindura muguhindura ubwiza bwingufu zamashanyarazi zabyaye, bigatuma yegera cyane umuyaga wa sine.Ikintu kinini kiranga imbaraga nyinshi nigiciro gito cya sisitemu.Nubwo bimeze bityo ariko, bigira ingaruka ku guhuza imirongo ya Photovoltaque no kugicucu igice, bikavamo imikorere nubushobozi bwa sisitemu yose yifotora.Muri icyo gihe, amashanyarazi yizewe ya sisitemu yose ya Photovoltaque yibasiwe nimikorere mibi yitsinda ryamafoto.Icyerekezo cyubushakashatsi buheruka ni ugukoresha umwanya wa vector modulasiyo yo kugenzura no guteza imbere imiterere mishya ya inverter topologiya kugirango ibone imikorere myiza murwego rwo gutwara ibintu.

Kuri SolarMax ihinduranya inverter, urashobora kwomekaho agasanduku k'ifoto ya Photovoltaque kugirango ukurikirane buri mugozi wamafoto yumuyaga.Niba imwe mumigozi idakora neza, sisitemu izohereza aya makuru kumugenzuzi wa kure Mugihe kimwe, uyu mugozi urashobora guhagarikwa no kugenzura kure, kugirango kunanirwa kwumugozi wumurongo wamafoto bitazagabanuka kandi bigira ingaruka kuri akazi nimbaraga zisohoka muri sisitemu yose ya Photovoltaque.

Imirongo ihindagurika yabaye inverter izwi cyane ku isoko mpuzamahanga.Umugozi inverter ushingiye kubitekerezo.Buri mugozi wa Photovoltaque (1kW-5kW) unyura muri inverter, ufite imbaraga ntarengwa zo gukurikiranwa kumpera ya DC, kandi uhujwe muburyo bubangikanye na AC.Amashanyarazi menshi manini yingufu zikoresha imirongo ikoresha inverter.Ibyiza nuko bidatewe ingaruka na module itandukanye nigicucu hagati yumurongo, kandi mugihe kimwe bigabanya uburyo bwiza bwo gukora bwa moderi ya Photovoltaque

Kudahuza na inverter, bityo byongera ingufu zamashanyarazi.Izi nyungu za tekiniki ntabwo zigabanya ibiciro bya sisitemu gusa, ahubwo binongera ubwizerwe bwa sisitemu.Muri icyo gihe, igitekerezo cya "shobuja-umugaragu" gitangizwa hagati y'imigozi, ku buryo iyo umugozi umwe w'ingufu z'amashanyarazi udashobora gukora inverter imwe ikora muri sisitemu, ibice byinshi by'imigozi ifotora bifatanyirizwa hamwe, kandi kimwe cyangwa benshi muribo barashobora gukora., Kugirango rero tubyare amashanyarazi menshi.Igitekerezo giheruka ni uko inverters nyinshi zigize "itsinda" ryo gusimbuza igitekerezo cya "shobuja-umugaragu", bigatuma kwizerwa kwa sisitemu gutera intambwe.Kugeza ubu, imirongo idahindura imirongo ifata iyambere.

Inverteri ya Multi-inverter ifata ibyiza bya inverteri hamwe na inverteri ikomatanya, ikirinda ibitagenda neza, kandi irashobora gukoreshwa kuri sitasiyo yamashanyarazi ya kilowati nyinshi.Muri iniverisite-inverteri, imbaraga zinyuranye zumurongo ukurikirana hamwe na DC-kuri-DC zirimo.Izi DC zahinduwe mumashanyarazi ya AC na inverter isanzwe ya DC-kuri-AC kandi ihujwe na gride.Indangagaciro zitandukanye zerekana imirongo ya Photovoltaque (nka: imbaraga zitandukanye zapimwe, umubare utandukanye wibigize muri buri mugozi, abakora ibice bitandukanye, nibindi), moderi yerekana amafoto yubunini butandukanye cyangwa ikoranabuhanga ritandukanye, hamwe nimirongo yicyerekezo gitandukanye (nka .

Igihe kimwe, uburebure bwumugozi wa DC buragabanuka, ingaruka igicucu hagati yimigozi nigihombo cyatewe no gutandukanya imirya iragabanuka.

Ibice bigize inverter nuguhuza buri foto yifotora na inverter, kandi buri kintu kigira imbaraga ntarengwa zo hejuru zikurikirana, kugirango ibice na inverter bihuze neza.Mubisanzwe bikoreshwa muri 50W kugeza 400W amashanyarazi yamashanyarazi, imikorere yose iri munsi yumurongo wa inverter.Kubera ko ihujwe kuburinganire kuri AC, ibi byongera ubunini bwinsinga kuruhande rwa AC kandi biragoye kuyikomeza.Ikindi kibazo kigomba gukemurwa nuburyo bwo guhuza gride neza.Inzira yoroshye nuguhuza byimazeyo na gride binyuze mumashanyarazi asanzwe ya AC, ishobora kugabanya ikiguzi nogushiraho ibikoresho, ariko akenshi ibipimo byumutekano wa gride ntibishobora kubimwemerera.Mugukora utyo, isosiyete ikora amashanyarazi irashobora kwanga ibikoresho bitanga amashanyarazi bihujwe neza na socket isanzwe yabakoresha urugo rusanzwe.Ikindi kintu kijyanye numutekano ni ukumenya niba impinduka yo kwigunga (inshuro nyinshi cyangwa inshuro nke) isabwa, cyangwa inverter idafite impinduka iremewe.Ibiinverterikoreshwa cyane murukuta rwumwenda.
