Hnub ci vaj huam sib luag inverters muaj nyob rau hauv ntau qhov ntau thiab tsawg.Lub watt (W) yog ib chav tsev siv los ntsuas lub zog ntawm lub inverter, ib yam li lub zog ntawm lub hnub ci vaj huam sib luag (W).Thaum xaiv qhov zoo tshaj plaws inverter loj, lub installer yuav xav txog qhov loj, hom ntawm lub hnub ci vaj huam sib luag, thiab tej yam tshwj xeeb ntawm koj qhov chaw installation.
Hnub Ci Array Loj
Qhov loj ntawm koj lub hnub ci array yog qhov tseem ceeb hauv kev txiav txim siab qhov loj ntawm koj lub hnub ci inverter.Lub hnub ci converter uas muaj peev xwm txaus yuav tsum hloov lub zog DC los ntawm lub hnub ci array rau AC zog.Piv txwv li, yog tias koj tsim lub hnub ci vaj huam sib luag nrog qhov ntsuas DC ntawm 5 kW, lub inverter yuav tsum muaj lub zog tso tawm ntawm 5,000 watts.Lub peev xwm array sib xws nrog cov inverter tshwj xeeb yuav muab rau ntawm inverter cov ntaub ntawv.Tsis muaj nqi nyob rau hauv kev siv lub inverter uas loj dhau los yog me me rau nws cov specifications.
Environmental Factors
Lub hnub ci npaum li cas tuaj yeem nkag mus rau lub hnub ci array yog qhov kev txhawj xeeb tseem ceeb rau kev teeb tsa hnub ci inverter.Txawm li cas los xij, ib puag ncig ib puag ncig, xws li duab ntxoov ntxoo thiab plua plav, tuaj yeem muaj kev cuam tshuam loj rau lub peev xwm ntawm lub hnub ci inverter.Cov kws tshaj lij coj cov xwm txheej no rau hauv tus account thaum xam tag nrho cov txiaj ntsig ntawm koj lub hnub ci vaj huam sib luag.Koj tuaj yeem siv koj lub kaw lus derating yam los kwv yees tus nqi hluav taws xob koj lub hnub ci vaj huam sib luag yuav tsim nyob rau hauv qhov tseeb installation.
Qee lub sij hawm lub hnub ci vaj huam sib luag uas muaj qhov ntxoov ntxoo, lossis lub ntsej muag sab hnub tuaj ntau dua li sab qab teb, yuav muaj qhov cuam tshuam ntau dua.Yog hais tias lub hnub ci vaj huam sib luag derating yog siab txaus, ces lub peev xwm inverter yuav qis dua tus txheeb ze rau qhov loj ntawm array.
Hom Solar Panels
Qhov chaw thiab cov yam ntxwv ntawm koj lub hnub ci array yuav txiav txim siab qhov loj ntawm koj lub hnub ci inverter.Qhov chaw ntawm lub hnub ci array, nrog rau kev taw qhia thiab lub kaum sab xis ntawm nws qhov kev teeb tsa, yuav cuam tshuam rau cov hluav taws xob uas nws tsim.Ntau hom hnub ci vaj huam sib luag muaj cov yam ntxwv tshwj xeeb uas yuav tsum tau xav txog ua ntej yuav ib qho inverter.
Muaj plaub yam tseem ceeb ntawm lub hnub ci vaj huam sib luag nyob rau hauv kev ua lag luam: lawv yog monocrystalline, polycrystalline, PERC, thiab nyias-film panels.Txhua tus muaj nws qhov zoo thiab qhov tsis zoo.Txawm li cas los xij, cov neeg siv yuav tsum tau nruab lub hnub ci vaj huam sib luag zoo tshaj plaws kom tau raws li lawv cov kev xav tau thiab cov kev xav tau.
Nkag siab txog DC / AC Ratio
DC / AC piv yog qhov piv ntawm qhov nruab DC muaj peev xwm rau AC lub zog ntsuas ntawm lub inverter.Ua lub hnub ci array loj dua qhov tsim nyog ua rau DC-AC hloov dua siab tshiab.Qhov no tso cai rau cov khoom siv hluav taws xob zoo dua thaum cov txiaj ntsig qis dua qhov kev ntsuas inverter, uas feem ntau yog cov ntaub ntawv thoob plaws hnub.
Rau feem ntau tsim, DC / AC piv ntawm 1.25 yog qhov zoo tagnrho.Qhov no yog vim hais tias tsuas yog 1% ntawm lub zog tsim tawm thoob plaws tag nrho cov photovoltaic (PV) array yuav muaj lub zog ntau dua 80%.Kev sib txuas ntawm 9 kW PV array nrog 7.6 kW AC converter yuav tsim qhov zoo tshaj plaws DC / AC piv.Nws yuav ua rau tsawg kawg ntawm lub zog poob.
Tshawb xyuas cov ntawv pov thawj thiab lav
Saib rau hnub ci inverters uas muaj ntawv pov thawj tsim nyog (xws li UL cov npe) thiab lav.Qhov no ua kom lub inverter ua tau raws li cov qauv kev nyab xeeb thiab muab kev txhawb nqa thaum muaj kev ua haujlwm tsis zoo.
Yog tias koj tsis paub meej txog qhov loj me hnub ci zog inverter rau koj cov kev xav tau tshwj xeeb, koj tuaj yeem sab laj SUNRUNE, peb muaj cov kws tshaj lij hnub ci tsim nyog thiab cov kws tshaj lij uas tuaj yeem ntsuas koj cov kev xav tau thiab muab cov lus qhia tshwj xeeb.
