Ekubeni injongo ye "carbon dual" yamiselwa, i-photovoltaic esasazwayo iye yathandwa ngenxa yeenzuzo zayo zokunciphisa ukukhutshwa kwekhabhoni ephantsi, iimeko ezahlukeneyo zesicelo kunye nokubuyiswa lula kutyalo-mali.Nangona kunjalo, ngokunyuka ngokukhawuleza komthamo ofakiweyo, kukho iindawo ezininzi zentlungu kwimarike, njenge-DC ephezulu yombane, impembelelo yombhobho, ubunzima bokusebenza kunye nokugcinwa ...... Oku kukhokelela kwiinkxalabo zokhuseleko kunye nokungabikho kwezinto ezifunwayo. imbuyekezo kutyalo-mali kubasebenzisi bokugqibela.
Kuba la manqaku entlungu angasentla, Wo Mai micro inverter ingasonjululwa lula.Ngoku, sidibanisa ingxaki yemarike yangoku, uhlalutyo olunzulu lwe-Wo Mai micro inverse solution, ukufumanisa.
01
Inqaku leentlungu zemarike # 1: Ukhuseleko
Kwiminyaka yakutshanje, imililo ye-photovoltaic yasekhaya ihlala rhoqo, i-80% ebangelwa yi-DC arc ebangelwa yi-inverter yendabuko ye-DC ephezulu yombane.Ngaphezu koko, iinkqubo ezinjalo ze-photovoltaic zihlala zifakwe eluphahleni lwezindlu okanye iifektri.Nje ukuba umlilo okanye uqhushumbo lwenzekile, luya kuzisa ilahleko yepropathi engenakulinganiswa kwaye ibeke ubomi emngciphekweni.
Ukongezelela, kusekho amakhulu okanye amawaka e-volts ye-DC kwinkqubo yokutshisa.Ukuba abacimi-mlilo bayakhawuleza ukuya kunceda, kunokuba nemiphumo ebuhlungu.Ngenxa yoko, abaphenduli bokuqala badla ngokulinda ukuba isityalo sitshise ngokupheleleyo ngaphambi kokuba baqale umsebenzi wabo, nto leyo edla ngokukhokelela ekulibazisekeni okukhulu kwimizamo yokucima umlilo.
Inkqubo 1
Ukhuseleko lwamandla ombane aphantsi, akukho ngozi yomlilo kunye nomngcipheko wokothuka wombane
Hemai inverter micro iqhagamshelwe kwinkqubo photovoltaic ngokunxuseneyo, ukwenza icala DC inkqubo uzinzo malunga 40V ombane ophantsi, ukusuka ingcambu ukuphelisa iingozi umlilo kunye nomngcipheko ukothuka yombane.Akukho mfuneko yokuba sibe nexhala malunga nomlilo we-DC arc kwisikhululo samandla sokubuyisela i-micro-retrograde.
Nangona inkqubo ye-inverter encinci inengxakeko ngenxa yezinto zangaphandle, emva kokuvala inkqubo, abaphenduli bokuqala abayi kujongana nomngcipheko wokutshatyalaliswa kombane ngenxa yokuba akukho mbane ophezulu we-DC kwisityalo se-PV.
02
Inqaku leentlungu zemarike 2: umphumo we-barrel
Iphaneli nganye ye-photovoltaic ineempawu ezahlukeneyo zokuphuma, njengangoku, i-voltage kunye neyona ndawo yokusebenza.Oku kungahambelani kuya kubonakala ngakumbi njengoko iinkqubo ze-photovoltaic zisetyenziselwa ngaphandle ixesha elide kunye nobudala ngokwemvelo.Iimpawu zokuvelisa amandla zenkqubo yendabuko ye-photovoltaic ihambelana kakhulu "nefuthe le-barrel yokhuni" : inkqubo ye-photovoltaic yendabuko yenzelwe uchungechunge, kwaye ukuveliswa kwamandla okupheleleyo koluhlu lweepaneli ze-photovoltaic kuxhomekeke ngakumbi kwiimpawu zokuphuma kwe-photovoltaic ebuthakathaka. Iphaneli kuthotho, nto leyo ethetha ukuba "ababuthathaka" ngokuqinisekileyo baya kutsala iqela phantsi kwaye bachaphazele ingeniso yokuvelisa amandla.
Ukhetho lwesi-2
Itekhnoloji yeMPPT yenqanaba lecandelo iphelisa isiphumo sombhobho
Kwimbono ye "cask effect", Wo Mai micro reverse iyeza.Umlawuli we-MPPT wecandelo layo ulandelela indawo ephezulu yamandla kwimodyuli nganye ye-PV ngokwahlukileyo.Nokuba imodyuli enye yePV ayisebenzi ngokufanelekileyo, ayiyi kuchaphazela ezinye iimodyuli zePV.Ngokomzekelo, kuyo yonke inkqubo ye-photovoltaic, ukuba icandelo lonakaliswe okanye livalwe, umlawuli ophezulu wokulandelela umbane wamanye amacandelo uya kuqhubeka nokugcina amandla abo aphezulu.
