Ngokuthuthukiswa kobuchwepheshe bemojula ye-Cell ne-PV, ubuchwepheshe obuhlukahlukene obufana ne-half cut cell, i-shingling module, i-bi-face module, i-PERC, njll. ibekwe phezulu komunye nomunye.Amandla okukhiphayo kanye namandla emojuli eyodwa akhule kakhulu.Lokhu kuletha izidingo eziphakeme kuma-inverters.
1.Amamojula Anamandla Aphezulu adinga Ukuguquguquka Kwamanje Okuphakeme Kwama-Inverters
I-Imp yamamojula we-PV yayicishe ibe ngu-8A esikhathini esidlule, ngakho-ke amandla okufakwayo aphezulu we-inverter ngokuvamile ayezungeze u-9-10A.Njengamanje, i-Imp yamamojula angu-350-400W aphezulu amandla idlule i-10A edingekayo ukuze ukhethe i-inverter enobukhulu obungu-12A okokufaka okwamanje noma ngaphezulu ukuze kuhlangatshezwane nemojula ye-PV yamandla aphezulu.
Ithebula elilandelayo libonisa amapharamitha ezinhlobo ezimbalwa zamamojula wamandla aphezulu asetshenziswa emakethe.Siyabona ukuthi i-Imp ye-module ye-370W ifinyelela ku-10.86A.Kufanele siqinisekise ubuningi bamanje bokufakwayo be-inverter ukweqa i-Imp yemojula ye-PV.
2.Njengoba amandla emojula eyodwa ekhuphuka, inani lezintambo zokufaka ze-inverter lingancishiswa ngokufanele.
Ngokukhula kwamandla amamojula we-PV, amandla eyunithi yezinhlamvu ngayinye nawo azokhula.Ngaphansi kwesilinganiso somthamo ofanayo, inombolo Yezintambo Zokufaka nge-MPPT ngayinye izokwehla.
Isilinganiso esiphezulu samanje se-Renac R3 Note Series 4-15K inverter yezigaba ezintathu ngu-12.5A, engahlangabezana nezidingo zamamojula we-PV wamandla aphezulu.
Sithatha amamojula angu-370W njengesibonelo ukulungisa amasistimu angu-4kW, 5kW, 6kW, 8kW, 10kW ngokulandelana.Imingcele eyinhloko yama-inverters imi kanje:
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 aphezulu etiyetha amamojula ngokuvamile awafinyelelwa 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:
Uma nje i-voltage yesifunda esiphezulu evulekile yentambo kanye ne-DC ephezulu yamanje ingaphakathi kokubekezelelana komshini, i-inverter ingasebenza ngokuxhuma negridi.
1.Isilinganiso esiphezulu se-DC samanje seyunithi yezinhlamvu ngu-10.86A, esingaphansi kuka-12.5A.
2.Ivolumu enkulu yesekethe evulekile yentambo ngaphakathi kwebanga le-MPPT ye-inverter.
Isifinyezo
Ngokuthuthuka okuqhubekayo kwamandla emojuli, abakhiqizi be-inverter badinga ukucabangela ukuhambisana kwama-inverter namamojula.Esikhathini esizayo esiseduze, amamojula we-500W+ PV anezinga eliphezulu lamanje angase abe inkambiso emakethe.I-Renac ifinyelela inqubekelaphambili ngokusungula izinto ezintsha nobuchwepheshe futhi izokwethula imikhiqizo yakamuva ukuze ihambisane nemojula ye-Power PV ephezulu.
