Kusukela kwabekwa umgomo "we-dual carbon", i-photovoltaic esabalalisiwe iye yathandwa ngenxa yezinzuzo zayo zokunciphisa ukukhishwa kwekhabhoni ephansi, izimo ezihlukene zokufaka isicelo kanye nokubuyisela kalula ekutshalweni kwezimali.Kodwa-ke, ngokukhula okusheshayo komthamo ofakiwe, kukhona nezindawo eziningi zobuhlungu emakethe, njenge-DC high voltage, umphumela we-barrel, ubunzima bokusebenza kanye nokugcinwa ...... Lokhu kuholela ekukhathazekeni kwezokuphepha kanye nokuntuleka kokufiswayo. ukubuyisela ekutshalweni kwezimali kubasebenzisi bokugcina.
Ngamaphuzu obuhlungu angenhla, i-Wo Mai micro inverter ingaxazululwa kalula.Manje, sihlanganisa inkinga yamanje yemakethe, ukuhlaziya okujulile kwesixazululo esiphambene ne-Wo Mai micro, ukuze sithole.
01
Iphuzu lobuhlungu bemakethe # 1: Ukuphepha
Eminyakeni yamuva nje, imililo ye-photovoltaic yasendlini ivamile, i-80% yayo ibangelwa i-DC arc ebangelwa inverter yendabuko DC high voltage.Ngaphezu kwalokho, izinhlelo ezinjalo ze-photovoltaic zivame ukufakwa ophahleni lwezindlu noma izimboni.Uma kwenzeka umlilo noma ukuqhuma, kuzoletha ukulahlekelwa kwempahla okungenakulinganiswa futhi kufake ngisho nezimpilo engozini.
Ngaphezu kwalokho, kusekhona amakhulu noma izinkulungwane zama-volts e-DC ohlelweni lomlilo.Uma izicishamlilo ziphuthuma ukuyohlenga, kungaba nemiphumela edabukisayo.Ngenxa yalokho, abaphenduli bokuqala bavame ukulinda ukuthi isitshalo sishiswe ngokuphelele ngaphambi kokuba baqale umsebenzi wabo, okuvame ukuholela ekubambezelekeni okukhulu kwemizamo yokucisha umlilo.
Uhlelo 1
Ukuphepha kwamandla kagesi aphansi, ayikho ingozi yomlilo kanye nengozi yokushaqeka kukagesi
I-Hemai micro inverter ixhunywe ohlelweni lwe-photovoltaic ngokuhambisana, okwenza uhlangothi lwe-DC lwesistimu luzinze cishe ku-voltage ephansi engu-40V, kusukela empandeni ukuze kuqedwe izingozi zomlilo kanye nobungozi bokushaqeka kukagesi.Akudingeki sikhathazeke ngomlilo we-DC arc esikhungweni samandla esine-micro-retrograde power.
Ngisho noma isistimu ye-inverter encane inesimo esiphuthumayo ngenxa yezici zangaphandle, ngemva kokuvala uhlelo, abaphenduli bokuqala ngeke babhekane nengozi yokushaqeka kukagesi ngoba ayikho i-DC high voltage esitshalweni se-PV.

Iphuzu lesi-2 lobuhlungu bemakethe: umphumela womgqomo
Iphaneli ngayinye ye-photovoltaic inezici ezihlukene zokukhipha, njengamanje, i-voltage kanye nephoyinti lokusebenza elilungile.Lokhu kungahambisani kuzobonakala nakakhulu njengoba izinhlelo ze-photovoltaic zisetshenziswa ngaphandle isikhathi eside futhi ubudala ngokwemvelo.Izici zokuphehla amandla zohlelo lwendabuko lwe-photovoltaic zihambisana kakhulu "nomphumela womgqomo wokhuni" : uhlelo lwendabuko lwe-photovoltaic lwenzelwe uchungechunge, futhi ukukhiqizwa kwamandla okuphelele kochungechunge lwamaphaneli e-photovoltaic kuncike kakhulu ezicini eziphumayo ze-photovoltaic ebuthakathaka. iphaneli ochungechungeni, okusho ukuthi "ababuthaka" nakanjani bazodonsela iqembu phansi futhi bathinte imali engenayo yokuphehla amandla.
Inketho yesi-2
Ubuchwepheshe be-MPPT bezinga lengxenye buqeda umphumela womgqomo
Ngokubuka "umphumela we-cask", umuthi we-Wo Mai micro reverse.Isilawuli se-MPPT yeleveli yengxenye yayo silandelela indawo yamandla ephezulu yemojuli ngayinye ye-PV ngokuhlukana.Ngisho noma imojuli eyodwa ye-PV ingasebenzi kahle, ngeke ithinte amanye amamojula e-PV.Isibonelo, kulo lonke uhlelo lwe-photovoltaic, uma ingxenye yonakalisiwe noma ivinjiwe, isilawuli sokulandelela amaphuzu wamandla esiphezulu sezinye izingxenye sizoqhubeka nokugcina ukusebenza kahle kwamandla aphezulu.
