Thaum nws los txoghnub ci vaj huam sib luag, ib qho ntawm cov lus nug ntau tshaj plaws uas tib neeg nug yog seb lawv puas tsim hluav taws xob hauv daim ntawv hloov pauv tam sim no (AC) lossis tam sim no ncaj qha (DC). Lo lus teb rau lo lus nug no tsis yog yooj yim li ib tug yuav xav, raws li nws nyob ntawm lub tshwj xeeb system thiab nws cov Cheebtsam.
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab txog cov haujlwm tseem ceeb ntawm cov hnub ci vaj huam sib luag. Hnub ci vaj huam sib luag yog tsim los ntes lub hnub ci thiab hloov mus rau hauv hluav taws xob. Cov txheej txheem no suav nrog kev siv cov cell photovoltaic, uas yog cov khoom ntawm cov hnub ci vaj huam sib luag. Thaum tshav ntuj hits cov hlwb, lawv tsim hluav taws xob tam sim no. Txawm li cas los xij, qhov xwm txheej ntawm qhov tam sim no (AC lossis DC) yog nyob ntawm hom kev kaw lus uas lub hnub ci vaj huam sib luag tau teeb tsa.
Feem ntau, cov hnub ci vaj huam sib luag tsim hluav taws xob DC. Qhov no txhais tau hais tias tam sim no ntws nyob rau hauv ib qho kev taw qhia ntawm lub vaj huam sib luag, mus rau lub inverter, uas ces converts nws mus rau hauv alternating tam sim no. Yog vim li cas yog tias feem ntau cov khoom siv hauv tsev thiab kab sib chaws nws tus kheej khiav ntawm AC fais fab. Yog li ntawd, rau cov hluav taws xob tsim los ntawm lub hnub ci vaj huam sib luag kom sib haum nrog cov qauv hluav taws xob tsim hluav taws xob, nws yuav tsum tau hloov los ntawm cov hluav taws xob ncaj qha mus rau qhov hloov tam sim no.
Zoo, cov lus teb luv luv rau lo lus nug "Puas yog hnub ci vaj huam sib luag AC lossis DC?" Cov yam ntxwv yog tias lawv tsim hluav taws xob DC, tab sis tag nrho cov kab ke feem ntau khiav ntawm AC zog. Qhov no yog vim li cas inverters yog ib feem tseem ceeb ntawm lub hnub ci fais fab. Tsis tsuas yog lawv hloov DC rau AC, tab sis lawv kuj tswj cov tam sim no thiab xyuas kom meej tias nws yog synchronized nrog daim phiaj.
Txawm li cas los xij, nws tsim nyog sau cia tias qee qhov xwm txheej, cov hnub ci vaj huam sib luag tuaj yeem teeb tsa kom ncaj qha tsim hluav taws xob AC. Qhov no feem ntau yog ua tiav los ntawm kev siv microinverters, uas yog me me inverters mounted ncaj qha rau ntawm tus kheej lub hnub ci vaj huam sib luag. Nrog rau qhov kev teeb tsa no, txhua lub vaj huam sib luag muaj peev xwm hloov lub hnub ci rau hauv kev hloov pauv tam sim no, uas muaj qee qhov zoo ntawm kev ua tau zoo thiab yoog raws.
Kev xaiv ntawm lub hauv paus inverter lossis microinverter nyob ntawm ntau yam, xws li qhov loj thiab qhov teeb tsa ntawm lub hnub ci array, lub zog tshwj xeeb xav tau ntawm cov cuab yeej, thiab qib kev saib xyuas yuav tsum tau ua. Thaum kawg, kev txiav txim siab seb puas yuav siv AC lossis DC hnub ci vaj huam sib luag (lossis ob qho sib xyaw ua ke) yuav tsum tau ua tib zoo xav thiab sab laj nrog tus kws tshaj lij hnub ci.
Thaum nws los txog rau AC vs DC teeb meem nrog lub hnub ci vaj huam sib luag, lwm qhov kev xav tseem ceeb yog lub zog poob. Thaum twg lub zog hloov dua siab tshiab los ntawm ib daim ntawv mus rau lwm qhov, muaj qhov kev poob qis uas cuam tshuam nrog cov txheej txheem. Rau cov tshuab hluav taws xob hnub ci, cov kev poob no tshwm sim thaum lub sij hawm hloov dua siab tshiab los ntawm tam sim no ncaj qha mus rau alternating tam sim no. Tau hais tias, kev nce qib hauv inverter thev naus laus zis thiab kev siv DC-coupled cia tshuab tuaj yeem pab txo qis cov kev poob no thiab txhim kho tag nrho cov txiaj ntsig ntawm koj lub hnub ci.
Nyob rau hauv xyoo tas los no, kuj tseem muaj kev txaus siab rau kev siv DC-coupled solar + storage systems. Cov tshuab no ua ke nrog cov hnub ci vaj huam sib luag nrog lub roj teeb cia, txhua qhov kev ua haujlwm ntawm DC sab ntawm qhov sib npaug. Txoj hauv kev no muaj qee qhov txiaj ntsig ntawm kev ua tau zoo thiab yoog raws, tshwj xeeb tshaj yog thaum nws los txog rau kev ntes thiab khaws cia ntau lub hnub ci zog rau kev siv tom qab.
Hauv cov ntsiab lus, cov lus teb yooj yim rau lo lus nug "Puas yog hnub ci vaj huam sib luag AC lossis DC?" yog tus cwj pwm los ntawm qhov tseeb tias lawv tsim DC lub zog, tab sis tag nrho cov kab ke feem ntau ua haujlwm ntawm AC fais fab. Txawm li cas los xij, cov kev teeb tsa tshwj xeeb thiab cov khoom siv ntawm lub hnub ci hluav taws xob tuaj yeem sib txawv, thiab qee zaum, cov hnub ci vaj huam sib luag tuaj yeem teeb tsa los tsim hluav taws xob AC ncaj qha. Thaum kawg, kev xaiv ntawm AC thiab DC hnub ci vaj huam sib luag yog nyob ntawm ntau yam, nrog rau cov cuab yeej tshwj xeeb xav tau lub zog thiab qib ntawm kev saib xyuas yuav tsum tau ua. Raws li lub hnub ci teb txuas ntxiv mus, peb yuav pom AC thiab DC hnub ci lub zog hluav taws xob txuas ntxiv mus ntxiv nrog kev tsom mus rau kev txhim kho kev ua tau zoo, kev ntseeg siab, thiab kev ruaj ntseg.
Yog tias koj txaus siab rau lub hnub ci vaj huam sib luag, txais tos hu rau cov chaw tsim khoom photovoltaic Radiance rautau ib nqe lus.
