Voltage thiab tam sim no yog ob qho tseem ceeb hluav taws xob yam ntxwv ntawm lub hnub ci vaj huam sib luag. Kev nkag siab txog qhov sib txawv ntawm lawv yog qhov tseem ceeb thaum xaiv cov qauv, tsim cov PV array thiab sib txuam panels nrog inverters, roj teeb thiab tus nqi tswj.
Hnub Ci Vaj Huam Sib Luag Voltage yog dab tsi?
Voltage sawv cev rau cov hluav taws xob muaj peev xwm sib txawv uas tsim los ntawm lub hnub ci vaj huam sib luag.
Cov ntaub ntawv hnub ci vaj huam sib luag feem ntau sau ntau qhov txiaj ntsig voltage, suav nrog:
Qhib - Circuit Court voltage (Voc)
Voltage ntawm lub zog siab tshaj plaws (Vmp)
Qhov siab tshaj qhov system voltage
Qhov qhib - voltage Circuit Court yog ntsuas thaum lub module tsis txuas nrog ib qho hluav taws xob load.
Qhov hluav taws xob ntawm lub zog siab tshaj plaws yog qhov hluav taws xob uas lub vaj huam sib luag tsim nws lub zog siab tshaj plaws nyob rau hauv cov xwm txheej ntsuas.
Hnub ci vaj huam sib luag tam sim no yog dab tsi?
Tam sim no piav qhia txog kev khiav ntawm hluav taws xob.
Common tam sim no specifications muaj xws li:
Luv-circuit tam sim no (Isc)
Tam sim no ntawm lub zog siab tshaj plaws (Imp)
Luv-circuit tam sim no sawv cev rau qhov tam sim no nyob rau hauv luv luv- Circuit Court kuaj mob, thaum tam sim no ntawm lub zog siab tshaj plaws yog txuam nrog lub module qhov ntsuas qhov siab tshaj plaws lub zog taw tes.
Yuav Ua Li Cas Voltage Thiab Tam Sim No Txiav Txim Siab
Kev sib raug zoo ntawm qhov hluav taws xob, tam sim no thiab lub zog tuaj yeem qhia tau tias:
Fais fab=Voltage × Tam sim no
Piv txwv li, yog tias ib qho module ua haujlwm ntawm 40 volts thiab 10 amps ntawm nws qhov siab tshaj plaws lub zog:
40V × 10A = 400W
Qhov no yog ib qho piv txwv yooj yim siv los piav txog kev sib raug zoo. Qhov tseeb hnub ci vaj huam sib luag specifications txawv ntawm cov khoom.
Vim li cas Voltage Thiab Tam sim no teeb meem
Thaum ntau lub vaj huam sib luag txuas ua ke, lawv cov yam ntxwv hluav taws xob cuam tshuam rau tag nrho cov kab ke.
Kev sib txuas cov modules hauv series feem ntau nce qhov system voltage thaum tam sim no tseem kwv yees li ntawm tus kheej module tam sim no.
Txuas cov modules nyob rau hauv parallel feem ntau nce tam sim no thaum voltage tseem kwv yees li ntawm cov module voltage.
Qhov kawg configuration yuav tsum nyob twj ywm nyob rau hauv lub khiav hauj lwm txwv ntawm lub inverter, tus nqi tswj thiab lwm yam system Cheebtsam.
Kub thiab Voltage
Hnub ci vaj huam sib luag voltage hloov nrog kub.
Raws li module kub nce, photovoltaic voltage feem ntau txo. Qhov no yog vim li cas qhov kub coefficients yog qhov tseem ceeb thaum tsim PV systems, tshwj xeeb tshaj yog nyob rau hauv cov huab cua kub.
Cov neeg tsim qauv tsim qauv yuav tsum xyuas lub vaj huam sib luag cov lus qhia hluav taws xob thoob plaws qhov kev cia siab ua haujlwm kub.
Nkag siab txog 12V Thiab 24V Panels
Cov khoom lag luam feem ntau yog 12V lossis 24V hnub ci vaj huam sib luag rau kev siv nrog cov roj teeb nominal sib xws.
Txawm li cas los xij, qhov tseeb module voltage feem ntau yog siab tshaj lub nominal roj teeb voltage.
Piv txwv li, lub hnub ci module npaj rau lub nominal 12V roj teeb system xav tau kev khiav hauj lwm qhov hluav taws xob txaus los them cov roj teeb ntawd los ntawm tus tswj hwm tus nqi tsim nyog.
Yog li ntawd, cov neeg yuav khoom yuav tsum tsis txhob xaiv lub vaj huam sib luag raws li "12V" lossis "24V" daim ntawv lo.
Sib piv cov hnub ci vaj huam sib luag nrog lwm cov khoom
Hluav taws xob sib raug zoo yuav tsum tau kuaj xyuas ua ntej txuas lub hnub ci vaj huam sib luag rau ib qho system.
Cov parameter tseem ceeb suav nrog:
Vmp
Voc
Imp
Isc
Qhov siab tshaj qhov system voltage
Inverter input ntau yam
Charge controller input range
Roj teeb voltage
Rau cov hnub ci loj dua, qhov voltage thiab tam sim no ntawm tag nrho cov hlua lossis array yuav tsum raug txiav txim siab.
Vim li cas cov ntaub ntawv tseem ceeb
Cov ntaub ntawv cov khoom lag luam muab cov ntaub ntawv hluav taws xob xav tau rau kev tsim qauv.
Hloov chaw ntawm kev sib piv cov hnub ci vaj huam sib luag tsuas yog los ntawm wattage, cov neeg yuav khoom yuav tsum kuaj xyuas cov khoom siv hluav taws xob tiav.
Kev nkag siab txog qhov voltage thiab tam sim no tuaj yeem pab cov neeg siv xaiv cov qauv uas ua haujlwm zoo nrog rau qhov seem ntawm PV system thiab zam cov teeb meem hluav taws xob sib raug zoo.
