Ngokuthuthukiswa kobuchwepheshe bemodyuli yeseli ne-PV, ubuchwepheshe obuhlukahlukene obufana nesigamu seseli, imodyuli ecwebezelayo, imodyuli ye-bichacial, i-perc, njll. Amandla okukhipha kanye namanje yemodyuli eyodwa akhule kakhulu. Lokhu kuletha izidingo eziphakeme kubabukeli.
Amamojula anamandla aphezulu adinga ukuvumelana okuphezulu kwamanje kwama-inverters
I-Imp of Imojula ye-PV yayizungeze i-10-11a esikhathini esidlule, ngakho-ke ukufakwa okuphezulu kwamanje kwe-inverter kwakuvame ukuba cishe ngo-11-12a. Njengamanje, i-Imp of 600W + Amamojula Amandla aphezulu sekwedlule i-15A edingekayo ukukhetha i-inverter enokufakwa okuphezulu kwe-15A okuphezulu noma ngaphezulu ukuze uhlangane nemodyuli ephezulu ye-PV.
Ithebula elilandelayo libonisa amapharamitha ezinhlobo eziningana zamamojula aphezulu asetshenziswa emakethe. Siyabona ukuthi i-Imp of the 600w bikhacial module ifinyelela ku-18.55a, okungaphandle komkhawulo wabaningi be-inverters emakethe. Kufanele siqinisekise ukuthi ukufakwa okuphezulu kwamanje kwe-inverter kukhulu kune-Imp of the module ye-PV.
Njengoba amandla e-module eyodwa akhuphuka, inani lezintambo zokufaka ze-inverter zingancishiswa ngokufanele.
Ngokwanda kwamandla amamojula we-PV, amandla entambo ngayinye nawo azokwanda. Ngaphansi kwesilinganiso esifanayo samandla, inani lezintambo zokufaka nge-MPPPT lizokwehla.
Yisiphi isixazululo uRenac anganikela?
Ngo-Ephreli 2021, uRenac ukhiphe uchungechunge olusha lwama-Inverters R3 pre Series 10 ~ 25 KWIBA ubuchwepheshe bamuva be-Power Electronics kanye ne-900V kuya ku-1100V kuya ku-1100V, futhi kuvumela ukuthi uhlelo luxhumeke amaphaneli amaningi, futhi lungagcina izindleko zamakhebula. Ngasikhathi sinye, inekhono le-150% DC ngokweqile. Ukufakwa okuphezulu kwamanje kwalolu chungechunge inverter kungu-30a nge-MPPT ngayinye, okungahlangabezana nezidingo zamamojula we-PV aphezulu.
Ukuthatha ama-500w 180mm kanye nama-600W 210mm amamojula we-bichacial njengesibonelo ukumisa amasistimu we-10kW, 15kW, 17kw, 20kw, 25kW, ngokulandelana. Amapharamitha asemqoka ama-inverterers anje:
Qaphela:
Lapho silungiselela uhlelo lwelanga, singabheka i-DC Oversize. I-DC Oversise Concept yamukelwa kabanzi ekwakhiweni kohlelo lweSolar System. Njengamanje, izitshalo zamandla e-PV zomhlaba wonke sezivele zivelele ngokwesilinganiso phakathi kuka-120% no-150%. Enye yezizathu eziphambili zokwenziwa ngokweqile i-DC generator ukuthi amandla we-theorretical the mojule ajwayele ukutholwa ngokoqobo. Kwezinye izindawo lapho kune-Irradiance ye-Insuradiance lapho i-Irradiance ye-Insu ffer, ukwengeza amandla (ukukhulisa umthamo we-PV ukwelula amahora okulayisha okugcwele) kuyindlela enhle. Idizayini enhle kakhulu yokweqisa kungenzeka ukuthi zombili zisiza uhlelo olusondele ekusebenzeni okugcwele futhi lugcine uhlelo ngaphansi kwesimo esinempilo, okwenza ukutshalwa kwemali kwakho kube yinzuzo.
Ukucushwa okunconyiwe kungokulandelayo:
Ngokokubalwa, ama-inverters e-renac angaqondanisa ngokuphelele amaphaneli we-500W kanye nama-600W bincac.
Ukubeka kafushane
Ngokuthuthuka okuqhubekayo kwamandla we-module, abakhiqizi be-inverter badinga ukubheka ukuhambisana kwama-inverters namamojula. Esikhathini esizayo esiseduze, amamojula we-210mm wafer 600W + PV anamanje aphezulu kungenzeka abe yimakethe yemakethe. URenac uzuza inqubekela phambili ngokuqamba kanye nobuchwepheshe futhi uzokwethula yonke imikhiqizo emisha ukufanisa namamojula we-PV aphezulu.
