YUAV UA LI CAS YUAV TSUM TAU TXAIS KOJ SOLAR PV SYSTEM

Thaum sib txuasSlocablehnub ci pv system, txoj hauv kev zoo tshaj plaws los ntxiv kev ruaj ntseg yog los ntawm kev sivMC4 fuse or Hnub ci Circuit Court breakers.Kev siv cov fuses thiab Circuit Court breakers yog qhov tseem ceeb kom muaj kev nyab xeeb.fuses thiab Circuit Court breakers yog siv los tiv thaiv cov xaim los ntawm kub heev thiab tseem tiv thaiv txhua yam khoom siv txuas nrog hauv lub cev kom tsis txhob tawg rau hauv nplaim taws lossis raug mob yog tias muaj kev cuam tshuam luv luv.Ib qho piv txwv zoo yog 12V lead acid roj teeb.Yog hais tias luv luv tsim nyob rau hauv koj AC / DC inverter piv txwv li, ib tug fuse ntawm nws thiab lub roj teeb yuav tiv thaiv tau tawg ntawm lub roj teeb thiab nws yuav txiav lub Circuit Court sai txaus los tiv thaiv cov xov tooj ntawm bursting rau hauv nplaim taws los yog kub txaus ntshai.Rau qhov xwm txheej no, lub roj teeb, cov xov hlau, thiab AC / DC inverter yuav raug cuam tshuam los ntawm lub fuse.Lawv tsis tsim nyog rau lub kaw lus khiav kom zoo, tab sis peb ib txwm hais kom siv fuses lossis Circuit Court breakers rau kev nyab xeeb.Muaj peb qhov chaw sib txawv uas peb xav kom txhim kho fuses lossis tawg: thawj zaug, nruab nrab ntawm tus nqi tswj thiab lub txhab nyiaj roj teeb, qhov thib ob, nruab nrab ntawm tus nqi tswj hwm thiab hnub ci vaj huam sib luag, thiab qhov thib peb yuav yog nruab nrab ntawm lub txhab nyiaj roj teeb thiab inverter.

Txhawm rau txiav txim siab qhov fuse loj yuav tsum tau ntawm tus tswj hwm thiab roj teeb lub txhab nyiaj koj tsuas yog phim qhov ntsuas amperage ntawm tus nqi tswj.

Qhov thib ob fuse nruab nrab ntawm koj lub hnub ci vaj huam sib luag thiab tus nqi tswj yog qhov txawv me ntsis kom paub meej.Qhov loj ntawm lub fuse no nyob ntawm seb koj muaj pes tsawg lub hnub ci vaj huam sib luag thiab lawv txuas nrog li cas (series, parallel, lossis series / parallel).Yog hais tias cov panels txuas nrog hauv series, qhov voltage ntawm txhua lub vaj huam sib luag yog ntxiv tab sis lub amperage nyob twj ywm tib yam.Piv txwv li, yog tias koj muaj plaub 100W vaj huam sib luag txuas nrog hauv series, txhua qhov ua tau 20 volts thiab 5 amps, tag nrho cov zis yuav yog 80 volts thiab 5 amps.Tom qab ntawd peb muab tag nrho cov amperage thiab muab faib los ntawm kev nyab xeeb ntawm 25% (5A x 1.25) muab peb qhov ntsuas fuse ntawm 6.25A lossis 10A yog tias peb sib npaug.Yog tias koj muaj kev sib txuas ua ke, qhov twg amperage ntawm cov vaj huam sib luag tau ntxiv txawm li cas los xij qhov hluav taws xob nyob twj ywm tib yam, koj yuav tsum tau ntxiv cov amperage ntawm txhua lub vaj huam sib luag thiab tom qab ntawd peb ntxiv 25% kev lag luam txoj cai los txheeb xyuas qhov loj ntawm fuse.Piv txwv li, yog tias koj muaj plaub 100W panels hooked nyob rau hauv ib qho kev sib txuas, txhua lub vaj huam sib luag tsim txog 5 Amps, yog li peb yuav siv qhov sib npaug no (4 * 5 * 1.25) = 28.75 Amps, yog li hauv qhov piv txwv no peb xav kom 30 Amp fuse. .

Kev lag luam hnub ci vaj huam sib luag nrog ntau dua 50 watts muaj 10 gauge xov hlau thiab tuaj yeem ua haujlwm tam sim no txog 30 amps.Yog tias cov vaj huam sib luag txuas nrog hauv koob, tam sim no yuav tsis nce, yog li txoj hlua tsis tas yuav tsum tau fused.Thaum koj txuas cov vaj huam sib luag nyob rau hauv parallel, qhov no tsis yog qhov teeb meem, vim hais tias thaum txuas mus rau hauv parallel, lub kaw lus tam sim no ntxiv.Piv txwv li, yog tias koj muaj 4 vaj huam sib luag, txhua qhov tuaj yeem muab tau txog 15A ntawm tam sim no, luv luv Circuit Court hauv ib lub vaj huam sib luag yuav ua rau tag nrho 60 A ntawm tam sim no ntws mus rau lub vaj huam sib luag luv.Qhov no yuav ua rau cov xov hlau ua rau lub vaj huam sib luag mus deb tshaj 30 amps, uas yuav ua rau ob lub xov hlau ntes hluav taws.Yog tias nws yog vaj huam sib luag, txhua lub vaj huam sib luag xav tau 30 amp fuse.Yog tias koj lub vaj huam sib luag tsawg dua 50 watts thiab koj tsuas yog siv 12 lub ntsuas hluav taws xob, koj xav tau 20 amp fuse.

Qhov kawg fuse uas peb hais hauv qhov system yuav yog tias koj siv lub inverter.Kev xaim thiab kev sib txuas ntawm lub roj teeb mus rau AC / DC inverter yog qhov tseem ceeb vim tias qhov no yog qhov siab tshaj plaws tam sim no tuaj yeem ntws.Qhov fuse no yuav nyob nruab nrab ntawm koj lub inverter thiab lub txhab nyiaj roj teeb.Qhov loj ntawm fuse yog ib txwm teev nyob rau hauv phau ntawv qhia thiab feem ntau inverters zoo li yuav muaj built-in fuses / Circuit Court breakers ntawm lub tswv yim thiab cov zis (AC) sab ntawm lub cuab yeej.Txoj cai ntawm tus ntiv tes xoo uas peb siv ntawm no yuav yog "Nruam Watts / Roj Teeb Lub Sijhawm Voltage 1.25, piv txwv li ib txwm 1000W 12V inverter kos ib ncig ntawm 83 txuas ntxiv amps thiab peb yuav ntxiv 25% kev nyab xeeb uas tawm mus rau 105 Amps, yog li peb xav kom 150A fuse.

Nov yog cov lus qhia luv luv thiab cov ntsiab lus tseem ceeb rau kev sib txuas koj lub cev.Muaj lwm yam xws li cable loj / ntev thiab fuse / breaker hom uas tseem ceeb.Koj ua tauxa emailYog xav paub ntxiv txog cov khoom siv hnub ci!Yog tias koj siv koj lub sijhawm thiab siv qhov sib xyaw ua ke ntawm cov khoom ntsuas, ces lub kaw lus yuav tsum ua haujlwm zoo thiab koj yuav pw tsaug zog zoo dua paub tias koj tau tsim nws kom muaj kev nyab xeeb thiab txhim khu kev qha.
