Nrog rau txoj kev loj hlob ntawm Cell thiab PV module technology, ntau yam technologies xws li ib nrab txiav cell, shingling module, bifacial 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.
High-Power Modules yuav tsum tau hloov kho tam sim no ntawm Inverters
Lub Imp ntawm PV modules nyob ib ncig ntawm 10-11A yav dhau los, yog li qhov siab tshaj plaws input tam sim no ntawm inverter feem ntau nyob ib ncig ntawm 11-12A. Tam sim no, Imp ntawm 600W + high-power modules tau tshaj 15A uas yog tsim nyog los xaiv ib tug inverter nrog ib tug siab tshaj plaws 15A 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 600W bifacial module nce mus txog 18.55A, uas yog tawm ntawm qhov txwv ntawm feem ntau ntawm cov hlua inverters ntawm lub khw. Peb yuav tsum xyuas kom meej qhov siab tshaj plaws cov tswv yim tam sim no ntawm lub inverter yog ntau tshaj qhov Imp ntawm PV module.
Raws li lub zog 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 yuav nce ntxiv. Raws li tib lub peev xwm piv, tus naj npawb ntawm Cov Khoom Siv Hluav Taws Xob rau MPPT yuav txo qis.
Qhov twg Renac tuaj yeem muab tau?
Nyob rau lub Plaub Hlis 2021, Renac tau tso tawm ib tug tshiab series ntawm inverters R3 Pre series 10 ~ 25 kW.Siv qhov tseeb fais fab electronics technology thiab thermal tsim tshuab los ua kom lub siab tshaj plaws DC input voltage los ntawm tus thawj 1000V rau 1100V, nws tso cai rau lub system mus txuas ntxiv. panels, kuj tuaj yeem txuag nqi cable. Nyob rau tib lub sijhawm, nws muaj 150% DC lub peev xwm loj dua. Qhov siab tshaj plaws cov tswv yim tam sim no ntawm no series inverter yog 30A ib MPPT, uas muaj peev xwm ua tau raws li qhov xav tau ntawm high-power PV modules.
Siv 500W 180mm thiab 600W 210mm bifacial modules ua piv txwv los teeb tsa 10kW, 15kW, 17kW, 20kW, 25kW systems feem. Qhov tseem ceeb ntawm cov inverter yog raws li nram no:
Nco tseg:
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:
Raws li kev suav, Renac inverters tuaj yeem phim 500W thiab 600W bifacial panels.
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, 210mm wafer 600W + PV modules nrog lub siab dua tam sim no yuav dhau los ua lub ntsiab ntawm kev ua lag luam. Renac tau ua tiav kev vam meej nrog kev tsim kho tshiab thiab thev naus laus zis thiab yuav tso tawm tag nrho cov khoom tshiab kom phim nrog siab zog PV modules.
