Nrog rau txoj kev loj hlob ntawm Cell thiab PV module technology, ntau yam technologies xws li ib nrab txiav cell, shingling module, bi-facial module, PERC, thiab lwm yam yog superimposed rau ib leeg.Lub zog tso zis thiab tam sim no ntawm ib qho module tau nce ntau.Qhov no coj cov kev xav tau siab dua rau inverter.
1.High-Power Modules uas yuav tsum tau hloov kho tam sim no ntawm Inverters
Lub Imp ntawm PV modules nyob ib ncig ntawm 8A yav dhau los, yog li qhov siab tshaj plaws input tam sim no ntawm inverter feem ntau nyob ib ncig ntawm 9-10A.Tam sim no, Imp ntawm 350-400W high-power modules tau tshaj 10A uas yog tsim nyog los xaiv ib tug inverter nrog ib tug siab tshaj plaws 12A input tam sim no los yog siab dua kom tau raws li high-power PV module.
Cov lus hauv qab no qhia txog qhov tsis muaj ntau yam ntawm cov khoom siv hluav taws xob siab uas siv hauv khw.Peb tuaj yeem pom tias Imp ntawm 370W module nce mus txog 10.86A.Peb yuav tsum xyuas kom meej qhov siab tshaj plaws tam sim no ntawm lub inverter kom tshaj qhov Imp ntawm PV module.
2.Raws li lub hwj chim ntawm ib qho module nce, tus naj npawb ntawm cov hlua input ntawm lub inverter tuaj yeem raug txo kom tsim nyog.
Nrog rau kev nce hauv lub zog ntawm PV modules, lub zog ntawm txhua txoj hlua kuj yuav nce ntxiv.Raws li tib lub peev xwm sib piv, tus naj npawb ntawm Cov Khoom Siv Hluav Taws Xob rau MPPT yuav txo qis.
Qhov siab tshaj plaws tam sim no ntawm Renac R3 Note Series 4-15K peb-theem inverter yog 12.5A, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob siab PV.
Noj 370W modules ua piv txwv los teeb tsa 4kW, 5kW, 6kW, 8kW, 10kW systems feem.Qhov tseem ceeb ntawm cov inverter yog raws li nram no:
Thaum peb teeb tsa lub hnub ci, peb tuaj yeem xav txog DC oversize.DC oversize tswvyim yog dav siv nyob rau hauv lub hnub ci system tsim.Tam sim no, PV fais fab nroj tsuag thoob ntiaj teb twb tau loj hlob nyob rau nruab nrab ntawm 120% thiab 150%.Ib qho ntawm cov laj thawj tseem ceeb rau kev loj hlob ntawm DC lub tshuab hluav taws xob yog qhov theoretical ncov lub zog ntawm cov modules feem ntau tsis ua tiav hauv kev muaj tiag.Hauv qee qhov chaw uas muaj qhov tsis txaus irradiance, qhov zoo tshaj plaws (nce PV muaj peev xwm txuas ntxiv AC lub sijhawm puv sijhawm) yog qhov kev xaiv zoo.Ib qho kev tsim loj loj tuaj yeem pab ob qho tib si kaw kom ua kom tag nrho thiab ua kom lub cev nyob rau hauv kev noj qab haus huv, uas ua rau koj cov peev txheej tsim nyog.
Qhov pom zoo configuration yog raws li nram no:
Ntev npaum li qhov siab tshaj plaws qhib Circuit Court voltage ntawm txoj hlua thiab qhov siab tshaj plaws DC tam sim no nyob rau hauv lub siab ntev ntawm lub tshuab, lub inverter tuaj yeem ua haujlwm txuas nrog daim phiaj.
1.Maximum DC tam sim no ntawm txoj hlua yog 10.86A, uas yog tsawg dua 12.5A.
2.Maxim qhib Circuit Court voltage ntawm txoj hlua nyob rau hauv lub inverter's MPPT ntau.
Cov ntsiab lus
Nrog rau kev txhim kho txuas ntxiv ntawm module lub zog, inverter manufacturers yuav tsum xav txog kev sib raug zoo ntawm inverters thiab modules.Nyob rau yav tom ntej, 500W + PV modules nrog lub siab dua tam sim no yuav dhau los ua lub hauv paus ntawm kev ua lag luam.Renac tau ua tiav kev vam meej nrog kev tsim kho tshiab thiab thev naus laus zis thiab yuav nthuav tawm cov khoom tshiab kom phim nrog ntau dua Power PV module.
