Hamwe niterambere rya tekinoroji ya Cell na PV, tekinoroji itandukanye nka kimwe cya kabiri cyakata selile, shingling module, bi-facial module, PERC, nibindi byashyizwe hejuru.Ibisohoka imbaraga nubu bigezweho module imwe yiyongereye cyane.Ibi bizana ibisabwa murwego rwo hejuru.
1.Ibihe Byinshi-Imbaraga Zisaba Guhuza Ibihe Byinshi byo Guhindura Inverters
Imp ya modules ya PV yari hafi 8A mugihe cyashize, kubwibyo kwinjiza byinshi muri inverter muri rusange byari hafi 9-10A.Kugeza ubu, Imp ya 350-400W yingufu-modules yarenze 10A ikenewe kugirango uhitemo inverter ifite 12A yinjiza nini cyangwa irenga kugirango ihuze imbaraga za PV module.
Imbonerahamwe ikurikira irerekana ibipimo byubwoko butandukanye bwimbaraga-modules zikoreshwa ku isoko.Turashobora kubona ko Imp ya module 370W igera kuri 10.86A.Tugomba kwemeza umubare munini winjiza wa inverter kugirango turenze Imp ya module ya PV.
2.Nkuko imbaraga za module imwe yiyongera, umubare winjiza imirongo ya inverter irashobora kugabanuka muburyo bukwiye.
Hamwe no kwiyongera kwimbaraga za PV modules, imbaraga za buri mugozi nazo ziziyongera.Muburinganire bumwe, umubare winjiza winjiza kuri MPPT uzagabanuka.
Umubare ntarengwa winjiza wa Renac R3 Icyitonderwa cyuruhererekane 4-15K inverter yicyiciro cya gatatu ni 12.5A, ishobora guhaza ibikenewe byingufu za PV nyinshi.
Gufata modules 370W nkurugero rwo gushiraho sisitemu ya 4kW, 5kW, 6kW, 8kW, 10kW.Ibyingenzi byingenzi bya inverters nibi bikurikira:
Mugihe dushyizeho imirasire y'izuba, dushobora gutekereza DC irenze.DC igereranya igitekerezo cyemewe cyane mugushushanya izuba.Kugeza ubu, amashanyarazi ya PV ku isi yose yamaze kugereranywa ugereranije hagati ya 120% na 150%.Imwe mumpamvu nyamukuru yo kugenzura amashanyarazi ya DC ni uko imbaraga za theoretical power power ya module akenshi itagerwaho mubyukuri.Mu turere tumwe na tumwe aho hamwe na insu fficient irradiance, kurenza urugero (kongera ubushobozi bwa PV kugirango wongere sisitemu AC amasaha yuzuye yuzuye) ni amahitamo meza.Igishushanyo cyiza cyane gishobora gufasha sisitemu hafi yo gukora neza kandi igakomeza sisitemu imeze neza, bigatuma igishoro cyawe gifite agaciro.
Ibisabwa byasabwe ni ibi bikurikira:
Mugihe cyose amashanyarazi ntarengwa afunguye yumurongo wumugozi hamwe na DC ntarengwa iri murwego rwo kwihanganira imashini, inverter irashobora gukora ihuza na gride.
1.Icyerekezo kinini cya DC cyumugozi ni 10.86A, kiri munsi ya 12.5A.
2.Imashanyarazi ntarengwa ifunguye yumurongo wumurongo uri muri MPPT ya inverter.
Incamake
Hamwe nogukomeza kunoza imbaraga za module, abakora inverter bakeneye gutekereza kubihuza na moderi.Mugihe cya vuba, modul ya 500W + PV hamwe numuyoboro mwinshi birashoboka ko bizahinduka isoko nyamukuru yisoko.Renac igera ku majyambere hamwe no guhanga udushya n'ikoranabuhanga kandi izashyira ahagaragara ibicuruzwa bigezweho kugirango bihuze na moderi yo hejuru ya Power PV.
