Ngokuthuthukiswa kobuchwepheshe bemodyuli yeseli ne-PV, ubuchwepheshe obuhlukahlukene obufana nengxenye yesigamu sokusika, imodyuli ecwebezelayo, i-bi-face module, i-perc, njll. Amandla okukhipha kanye namanje yemodyuli eyodwa akhule kakhulu. Lokhu kuletha izidingo eziphakeme kubabukeli.
Amamojula we-1.Igh-Power adinga ukuguquguquka okuphezulu kwamanje kwama-inverters
I-Imp of Imojula ye-PV yayizungeze i-8A Esikhathini esedlule, ngakho-ke ukufakwa okuphezulu kwe-inverter bekuvame ukuzungeza u-9-10a. Njengamanje, i-Imp of 350-400W amamojula aphezulu adlule we-10a okudingekayo ukukhetha inserter enokufakwa okuphezulu kwe-12a okufakiwe noma ngaphezulu ukuze uhlangane nemodyuli ephezulu ye-PV.
Ithebula elilandelayo libonisa amapharamitha ezinhlobo eziningana zamamojula aphezulu asetshenziswa emakethe. Siyabona ukuthi i-Imp of the Module 370W ifinyelela ku-10.86a. Kufanele siqinisekise ukuthi okufakwayo okuphezulu kwamanje kwe-inverter ukwedlula i-Imp of module ye-PV.
2.Amandla we-module eyodwa ekhuphuka, inani lezintambo zokufaka ze-inverter zingancishiswe ngokufanele.
Ngokwanda kwamandla amamojula we-PV, amandla entambo ngayinye nawo azokwanda. Ngaphansi kwesilinganiso esifanayo samandla, inani lezintambo zokufaka nge-MPPPT lizokwehla.
Ukufakwa okuphezulu okuphezulu kwamanje kweRenac R3 Report Series 4-15k 3-15k ezintathu-isigaba inverter kuyinto engu-12.5a, engahlangabezana nezidingo zamamojula we-PV aphezulu.
Ukuthatha amamojula angama-370W njengesibonelo sokulungiselela ama-4kw, 5kw, 6kw, 8kw, 10kW, 10kW ngokulandelana. Amapharamitha asemqoka ama-inverterers anje:
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:
Uma nje i-voltage ephakeme yesifunda evulekile yentambo kanye ne-DC yamanje ye-DC ingabekezeleli komshini, i-inverter ingasebenza ukuxhumana negridi.
I-1.Maximum DC yamanje yentambo yi-10.86a, engaphansi kwe-12.5a.
I-2.Maximum evule i-Volcuity Voltage yentambo ngaphakathi kwe-Inverter's MPPT Range.
Ukubeka kafushane
Ngokuthuthuka okuqhubekayo kwamandla we-module, abakhiqizi be-inverter badinga ukubheka ukuhambisana kwama-inverters namamojula. Esikhathini esizayo esiseduze, amamojula we-500W + PV anamanje aphezulu kungenzeka abe yimakethe yemakethe. I-Renac ifinyelela inqubekelaphambili ngokuqamba kanye nobuchwepheshe futhi izokwethula imikhiqizo yakamuva ukuze ifane nemodyuli ephezulu ye-PV.
