Ngokuthuthukiswa kobuchwepheshe bemojula ye-Cell ne-PV, ubuchwepheshe obuhlukahlukene obufana ne-half cut cell, i-shingling module, i-bifacial module, i-PERC, njll. Amandla okukhiphayo kanye namandla emojuli eyodwa akhule kakhulu. Lokhu kuletha izidingo eziphakeme kuma-inverters.
Amamojula Anamandla Aphezulu adinga Ukuguquguquka Kwamanje Okuphakeme Kwama-Inverters
I-Imp yamamojula we-PV yayizungeze i-10-11A esikhathini esidlule, ngakho-ke amandla okufakwayo aphezulu we-inverter ngokuvamile ayezungeze i-11-12A. Njengamanje, i-Imp yamamojula angu-600W+ amandla aphezulu idlule ku-15A okudingekayo ukuze ukhethe isiguquli esinamandla sokufaka esingu-15A samanje noma ngaphezulu ukuze sihlangabezane nemojula yamandla aphezulu we-PV.
Ithebula elilandelayo libonisa amapharamitha ezinhlobo ezimbalwa zamamojula wamandla aphezulu asetshenziswa emakethe. Siyabona ukuthi i-Imp ye-600W bifacial module ifinyelela ku-18.55A, engaphandle komkhawulo wama-inverter amaningi ezintambo emakethe. Kufanele siqinisekise ukuthi ubuningi bamanje bokufakwayo be-inverter bukhulu kune-Imp yemojula ye-PV.
Njengoba amandla emojula eyodwa ekhula, inani lezintambo zokufaka ze-inverter lingancishiswa ngokufanelekile.
Ngokukhula kwamandla amamojula we-PV, amandla eyunithi yezinhlamvu ngayinye nawo azokhula. Ngaphansi kwesilinganiso somthamo ofanayo, inombolo Yezintambo Zokufaka nge-MPPT ngayinye izokwehla.
Isiphi Isixazululo i-Renac esingasinikeza?
Ngo-April 2021, i-Renac yakhipha uchungechunge olusha lwama-inverter R3 Pre series 10~25 kW. Isebenzisa ubuchwepheshe bakamuva bamandla kagesi kanye nobuchwepheshe bomklamo oshisayo ukuze kukhuliswe amandla kagesi okufaka aphezulu e-DC ukusuka ku-1000V yasekuqaleni kuya ku-1100V, kuvumela uhlelo ukuthi luxhumeke kakhudlwana. amaphaneli, futhi angasindisa izindleko zekhebula. Ngesikhathi esifanayo, inamandla angaphezu kuka-150% we-DC. Ubuningi bamanje bokufakwayo balolu chungechunge lwe-inverter yi-30A nge-MPPT ngayinye, engahlangabezana nezidingo zamamojula we-PV wamandla aphezulu.
Kuthatha 500W 180mm kanye 600W 210mm 210mm bifacial modules njengesibonelo ukulungisa 10kW, 15kW, 17kW, 20kW, 25kW izinhlelo ngokulandelana. Imingcele eyinhloko ye-inverters imi kanje:
Qaphela:
Lapho silungiselela isistimu sonozungezilanga, singacabangela i-DC oversize. Umqondo we-DC oversize wamukelwa kabanzi ekwakhiweni kwesistimu yelanga. Njengamanje, izitshalo zikagesi ze-PV emhlabeni wonke sezivele zikhulu ngokwesilinganiso phakathi kuka-120% no-150%. Esinye sezizathu eziyinhloko zokweqisa ijeneretha ye-DC ukuthi amandla aphakeme etiyetha amamojula ngokuvamile awafinyeleli eqinisweni. Kwezinye izindawo lapho ngaphandle kwe-irradiance enganele, ukweqisa okuhle (ukwandisa umthamo we-PV ukuze kunwetshwe amahora okulayisha agcwele esistimu ye-AC) kuyinketho enhle. Idizayini enhle eyeqile ingasiza isistimu ukuthi isondele ekusebenzeni ngokugcwele futhi igcine isistimu ingaphansi kwesimo esinempilo, okwenza utshalomali lwakho lube lusizo.
Ukucushwa okunconyiwe kungokulandelayo:
Ngokwezibalo, ama-inverter e-Renac angafanisa ngokuphelele amaphaneli angama-bifacial angama-500W nama-600W.
Isifinyezo
Ngokuthuthuka okuqhubekayo kwamandla emojuli, abakhiqizi be-inverter badinga ukucabangela ukuhambisana kwama-inverter namamojula. Esikhathini esizayo esiseduze, amamojula angama-210mm wafer 600W+ PV anezinga eliphezulu lamanje angase abe inkambiso yemakethe. I-Renac ifinyelela inqubekelaphambili ngokusungula izinto ezintsha nobuchwepheshe futhi izokwethula yonke imikhiqizo emisha ukuze ihambisane namamojula aphezulu we-Power PV.
