Umehluko wama-Micro-inverters kanye nama-Series-inverters

Kuhlelo lokukhiqiza amandla e-photovoltaic, i-inverter ingenye yemishini eyinhloko ebaluleke kakhulu.Phakathi kwabo, ama-inverters ama-micro kanye nama-inverters ochungechunge yizinhlobo ezimbili ezivamile, futhi zihluke komunye nomunye ngezindlela eziningi.
I-1.Wisimiso se-orking
Mikhro-i-inverter
I-inverter encane yenza ngokwehlukana i-MPPT kumojula ngayinye ye-photovoltaic, futhi i-DC ekhiqizwa yi-module iguqulwa ngokuqondile ku-AC bese ifakwa kugridi.I-micro-inverter ngayinye isebenza ngokuzimela futhi ayiphazamisi abanye.
Njengoba bekunjalo, uhlelo olusophahleni olunamamojula we-PV amaningana afakiwe, ngisho noma ingxenye eyodwa ifakwe umthunzi noma ihluleka, ezinye izingxenye zingakwazi ukukhipha ugesi ngamandla amakhulu ngokusebenzisa ama-micro-inverters azo, ngaleyo ndlela akhulise ukusebenza kahle kokukhiqizwa kwamandla kohlelo.
Series-i-inverter
I-inverter yochungechunge uchungechunge lwamamojula amaningana e-photovoltaic abe uchungechunge, lonke uchungechunge lokulandelela amaphuzu wamandla aphezulu.Khona-ke, okwamanje okuqondile okukhiqizwa uchungechunge kuguqulelwa kumanje okushintshanayo futhi kufakwe kugridi yamandla.
Uma ingxenye eyodwa kuyunithi yezinhlamvu inezinkinga, njengokuvinjwa noma ukulimala, ingaba nomthelela emandleni okukhiphayo ayo yonke iyunithi yezinhlamvu futhi ngaleyo ndlela ithinte ukusebenza kahle kokukhiqizwa kwamandla kwesistimu.

2.Isakhiwo sesistimu
I-Micro-inverter
Incane futhi ihlangene, ngokuvamile ingafakwa ngqo ngemuva noma ohlangothini lwemodule ye-photovoltaic ngaphandle kwesikhala sokufaka esengeziwe.Lokhu kuklama okuhlanganisiwe kwenza uhlelo lube lula futhi luhle kakhulu kodwa futhi lunciphisa ubunzima bezintambo.
Ngokusebenzisa i-micro-inverter yokufakwa ohlelweni lwe-photovoltaic ophahleni lwasekhaya, lulula kakhulu, ngeke luthathe isikhala esiningi, futhi lube nokufanelana okuphelele kwezinhlobo ezahlukene zamamojula we-photovoltaic.
I-inverter yochungechunge
Umthamo bukhulu kakhulu futhi udinga ukufakwa ku-inverter ekhethekile yasendlini noma ngaphandle kwekhabhinethi.I-inverter yochungechunge kanye nemodyuli ye-photovoltaic idinga ukuxhunywa ngekhebula le-DC ende, okwandisa izindleko zokufakwa kwesistimu nokulahlekelwa komugqa.
Amakamelo amaningana e-inverter asethwe esiteshini esikhulu samandla e-photovoltaic, futhi ama-inverter ochungechunge afakwe phakathi nendawo ukuze kuzuzwe ukuphathwa nokugcinwa okuhlangene.

3.Izinhlamvu zokusebenza
Isizukulwane Ngempumelelo
Micro-i-inverter: Ngenxa ye-MPPT ezimele yengxenye ngayinye, ingakwazi ukuzivumelanisa kangcono nezimo zokukhanya ezihlukene kanye nokuvala ithunzi.Ngakho-ke, ukusebenza kahle kokukhiqizwa kwamandla kuphezulu endaweni eyinkimbinkimbi. Ngisho noma ezinye izingxenye zithinteka isithunzi, ezinye izingxenye zisasebenza ngokujwayelekile, futhi awukho umphumela wombhobho.
Umzila-i-inverter: Nakuba i-MPPT ingabuye ibonakale ngoba yonke intambo ilandelwa, uma ezinye izingxenye zentambo sezinciphise noma zivimbe ukusebenza, amandla okukhipha intambo yonke azothinteka, ngaleyo ndlela kuncishiswe ukusebenza kahle kokukhiqizwa kwamandla kwesistimu. Ukwethembeka
Micro-i-inverter: I-micro-inverter ngayinye isebenza ngokuzimela;ngisho noma eyodwa yehluleka, enye izoqhubeka isebenza ngendlela evamile.Ngaphezu kwalokho, ama-microinverter asekelwe kubuchwepheshe obuthuthukisiwe be-elekthronikhi, okuhlanganisa nomklamo wokulahla ukushisa obenza bathembeke kakhulu futhi bazinze.
Umzila-i-inverter: Endabeni yephutha, mhlawumbe intambo yonke ingase ingakwazi ukukhiqiza ngokujwayelekile, okuthinta ukwethembeka kwesistimu.Futhi, ukulungisa iphutha nokugcinwa kwe-inverter yochungechunge kuyinkimbinkimbi futhi kudinga abasebenzi abangochwepheshe nabachwepheshe ukuze basebenze.
I-Micro-inverter: Okukhiphayo kuyi-low-voltage AC, ngokuvamile engu-220V noma i-110V, enciphisa kakhulu ingozi yokuphepha ebangelwa i-DC high voltage.Ngaleso sikhathi, i-micro-inverter nayo inemisebenzi yokuvikela ephelele, njengokuvikela u-overvoltage, ukuvikelwa kwe-overcurrent, ukuvikelwa kwesekethe emfushane, njll., ukuqinisekisa ukusebenza okuphephile kwesistimu.
Series-i-inverter: Okukhiphayo amandla aqondile kagesi aphezulu, ngakho kunezingozi ezithile zokuphepha. Uma ikhebula le-DC lilimele noma limiswe phansi ngokungalungile, izingozi ezifana nokushaqeka kukagesi noma umlilo zingase zenzeke.
4.Izimo Zohlelo Lokusebenza
Mikhro-i-inverter
Kufakwe ezinhlelweni ezincane ezisatshalaliswa ze-photovoltaic, ezifana nophahla lwezindawo zokuhlala ezizimele, uphahla lwezakhiwo zezentengiselwano, njalonjalo.Ngaphansi kwalezi zimo, indawo yokufaka imodyuli ye-photovoltaic ihlakazeka, futhi izimo zokukhanyisa zihlukile.Kulapha lapho ama-micro-inverters angadlala izinzuzo zabo ngokuqinile ukuze kuthuthukiswe ukusebenza kahle kokukhiqizwa kwamandla nokuthembeka kwesistimu.
Ezindaweni ezinezidingo eziphakeme zobuhle, ukwakheka okudidiyelwe kwama-inverter amancane nakho kuzohlangabezana nezidingo zabasebenzisi.
Series-i-inverter
Ifanele izitshalo ezinkulu zamandla e-photovoltaic emhlabathini kanye ne-Industrial and commercial rooftop photovoltaic systems.Kulezi zimo, isikali sokufakwa kwamamojula we-photovoltaic sikhulu, futhi i-inverter yochungechunge ingahlangabezana kangcono nezidingo zamandla zesistimu futhi inciphise izindleko.
Ezindaweni ezinendawo eyisicaba kanye nezimo zokukhanya ezingaguquki, ama-inverter ochungechunge nawo angadlala ukusebenza okungcono.

5. Ukuhlaziywa kwezindleko
Izindleko zokuqala zokutshala imali
Micro-i-inverter: Ngenxa yokuqukethwe kwayo okuphezulu kwezobuchwepheshe kanye nenqubo yokukhiqiza eyinkimbinkimbi, intengo iphakeme kakhulu.Ngaphezu kwalokho, ngoba ingxenye ngayinye idinga ukuhlonyiswa nge-micro-inverter, izindleko zokuqala zokutshala izimali zizoba phezulu uma uhlelo luncane.
Series-i-inverter: Intengo yama-inverters ochungechunge iphansi kakhulu, ikakhulukazi kuzicelo ezinkulu, futhi inzuzo yezindleko isobala kakhulu.

Izindleko zokusebenza nokunakekela
Micro-i-inverter: Ngenxa yokuthembeka kwayo okuphezulu kanye nezinga eliphansi lokuhluleka, izindleko zokusebenza nezokugcina ziphansi kakhulu.Ngaphezu kwalokho, i-inverter encane ingabhekwa futhi iphathwe ukude ngenethiwekhi, elula futhi esheshayo.
Series-i-inverter: Izindleko zokusebenza nokugcinwa kwazo ziphezulu uma kuqhathaniswa.Ikakhulukazi uma kukhona ukwehluleka, izisebenzi ezingochwepheshe nezobuchwepheshe zidinga ukuphenya nokukulungisa, okudla isikhathi nezindleko zomsebenzi.

Ngokuvamile, ama-inverter ama-micro kanye nama-inverter ezintambo anezici eziningi ezihlukene nezisobala kumgomo wokusebenza, ukwakheka kwesistimu, ukusebenza, izimo zohlelo lokusebenza, kanye nezindleko.Ukukhethwa kwe-Inverter kuzocabangela kabanzi izimo zohlelo lokusebenza kanye nezidingo zokusebenza okuphelele kanye nenzuzo yezomnotho yohlelo.
