Nrog rau kev txhim kho ntawm tes thiab PV module thev naus laus zis, ntau yam kev txiav ib nrab txiav cortru, bifag module, perc, thiab lwm yam yog superimposed ntawm txhua lwm yam. Cov zis zog thiab tam sim no ntawm ib qho qauv tau nce ntau. Qhov no coj kev yuav tsum muaj cov inverters.
High-zog cov qauv xav tau ntau dua qhov hloov tau ntawm Inverters
Tus Imp ntawm PVules tau nyob ib ncig ntawm 10-11A yav dhau los, yog li cov lus tshaj tawm tam sim no ntawm Inverter feem ntau yog ib puag ncig 11-12a. Ntawm tam sim no, Imp ntawm 600W + High-zog cov qauv tau tshaj 15a uas yog qhov tsim nyog los xaiv qhov siab tshaj plaws 15A cov tswv yim tam sim no lossis siab dua kom tau raws li lub zog PV module.
Cov lus hauv qab no qhia tau cov tsis muaj ntau yam ntawm ntau hom high-zog modules uas siv hauv khw. Peb tuaj yeem pom tias tus Imp ntawm 600W BIFACial module ncav cuag 18.55A, uas yog tawm ntawm qhov txwv ntawm feem ntau ntawm txoj hlua inverters ntawm kev ua lag luam. Peb yuav tsum ua kom ntseeg tau qhov siab tshaj plaws ntawm cov inverter yog ntau dua li tus Imp ntawm PV module.
Raws li lub zog ntawm ib qho module nce ntxiv, tus naj npawb ntawm cov hlua tawm ntawm lub inverter tuaj yeem raug txo qis.
Nrog rau kev nce hauv lub zog ntawm PV modules, lub zog ntawm txhua txoj hlua yuav tseem nce ntxiv. Raws li tib lub peev xwm piv, tus naj npawb ntawm cov hlua tawm ib qho MPPT yuav txo qis.
Txoj kev daws teeb meem twg?
Nyob rau hauv lub Plaub Hlis 2021, Renac tawm cov tshiab ntawm inverters R3 Pre-~v tsim hluav taws xob voltage los ntawm cov ntawv loj tshaj plaws, tseem tuaj yeem txuag cov nqi cable. Nyob rau tib lub sijhawm, nws muaj 150% DC Oversize muaj peev xwm. Qhov siab tshaj plaws ntawm cov series Inverter yog 30A rau ib MPP, uas tuaj yeem ua kom tau raws li qhov xav tau ntawm high-power PV modules.
Noj 500W 180mm thiab 600W 210mm Bifagial Modules ua piv txwv rau teeb tsa 10KW, 17kW, 20kw system muaj feem. Tus yuam sij ntawm lub inverters yog raws li hauv qab no:
Nco tseg:
Thaum peb tsim kho lub hnub ci, peb tuaj yeem xav txog DC Oversize. DC Oversize tswvyim yog dav tau txais hauv kev tsim qauv hnub ci. Tam sim no, PV lub hwj huam ntoo thoob ntiaj teb yog twb qhib tau qhov nruab nrab ntawm 120% thiab 150%. Ib qho ntawm cov laj thawj tseem ceeb rau kev nce qib DC yog qhov theoretical ncov lub zog ntawm cov modules yog feem ntau tsis tiav hauv kev muaj tiag. Hauv qee thaj chaw uas muaj insu ffiecic irersizian, ua kom muaj zog pv ntxiv rau txuas cov txheej txheem ntev puv-cov xaij) yog qhov kev xaiv zoo. Ib qho kev tsim qauv zoo tuaj yeem ob qho tib si kom muaj lub kaw lus kaw rau kev ua kom tag nrho thiab ua kom lub kaw lus zoo, uas ua rau koj cov peev txheej muaj nuj nqis.
Cov kev pom zoo teeb tsa yog raws li hauv qab no:
Raws li cov kev suav, cov renac inverers tuaj yeem sib phim nrog 500W thiab 600W cov khoom sib dhos bifacial.
Lub ntsiab
Nrog rau kev txhim kho txuas ntxiv ntawm module lub zog, inverter tuam ntxhab yuav tsum xav txog qhov sib xyaw ntawm inverters thiab modules. Nyob rau yav tom ntej ze, 210mm Wafer 600W + PV cov qauv nrog cov siab dua tam sim no yog yuav dhau los ua lub ntsiab ntawm kev ua lag luam. Renac tau ua tiav kev nce qib nrog kev hloov pauv thiab thev naus laus zis thiab yuav tso txhua cov khoom lag luam tshiab kom phim nrog cov zog PVules.
