Lub off-grid inverter yog lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob off-grid, uas hloov DC lub zog rau hauv AC lub zog siv los ntawm AC loads.
2. Daim ntawv thovAreas
Off-grid photovoltaic fais fab kev tsim hluav taws xob tau siv dav hauv thaj chaw deb, thaj chaw tsis muaj hluav taws xob, thaj chaw tsis muaj hluav taws xob, thaj chaw uas tsis muaj hluav taws xob tsis zoo, cov Islands tuaj, cov chaw sib txuas lus thiab lwm qhov chaw thov.
Peb lub hauv paus ntsiab lus ntawm photovoltaic off-grid system tsim
1. Paub meej tias lub hwj chim ntawm off-grid inverter raws li tus neeg siv lub load hom thiab lub zog:
Cov khoom siv hauv tsev feem ntau muab faib ua inductive loads thiab resistive loads.Loads nrog motors xws li tshuab ntxhua khaub ncaws, cua txias, tub yees, twj tso kua mis, thiab ntau hoods yog inductive loads.Lub zog pib ntawm lub cev muaj zog yog 5-7 npaug ntawm lub zog ntsuas.Lub zog pib ntawm cov loads no yuav tsum tau coj mus rau hauv tus account thaum lub zog siv.Lub zog tso zis ntawm lub inverter yog ntau dua li lub zog ntawm lub load.Xav tias tag nrho cov loads tsis tuaj yeem tig rau tib lub sijhawm, txhawm rau txuag cov nqi, cov txiaj ntsig ntawm lub zog thauj khoom tuaj yeem muab faib ua qhov sib npaug ntawm 0.7-0.9.
2. Paub meej tias lub zog tivthaiv raws li tus neeg siv khoom siv hluav taws xob txhua hnub:
Lub hauv paus ntsiab lus tsim qauv ntawm lub module yog ua kom tau raws li qhov xav tau ntawm kev siv hluav taws xob niaj hnub ntawm cov khoom thauj hauv nruab nrab huab cua.Rau kev ruaj ntseg ntawm lub system, cov hauv qab no yuav tsum tau xav txog
(1) Cov huab cua nyob qis dua thiab siab dua qhov nruab nrab.Hauv qee thaj chaw, qhov teeb pom kev zoo nyob rau lub caij nyoog phem tshaj plaws yog qis dua qhov nruab nrab txhua xyoo;
(2) Lub zog tsim hluav taws xob tag nrho ntawm lub tshuab hluav taws xob photovoltaic off-daim phiaj hluav taws xob tsim hluav taws xob, suav nrog kev ua haujlwm ntawm hnub ci vaj huam sib luag, cov tswj hwm, inverters thiab roj teeb, yog li lub zog tsim hluav taws xob ntawm lub hnub ci vaj huam sib luag tsis tuaj yeem hloov mus rau hauv hluav taws xob tag nrho, thiab cov hluav taws xob muaj nyob hauv. lub off-grid system = Cheebtsam Tag nrho cov hwj huam * nruab nrab ncov teev ntawm hnub ci zog tiam * hnub ci vaj huam sib luag them efficiency * xws li efficiency * inverter efficiency * roj teeb efficiency;
(3) Lub peev xwm tsim ntawm lub hnub ci cell modules yuav tsum ua tib zoo xav txog cov kev ua haujlwm tiag tiag ntawm kev thauj khoom (sib npaug load, raws caij nyoog thauj khoom thiab sib cuam tshuam) thiab cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom;
(4) Nws tseem yuav tsum tau xav txog kev rov qab los ntawm lub peev xwm ntawm lub roj teeb nyob rau hauv cov hnub tsis ntev los nag lossis tshaj tawm, kom tsis txhob cuam tshuam rau lub neej kev pab cuam ntawm lub roj teeb.
3. Txiav txim siab lub peev xwm roj teeb raws li tus neeg siv lub zog noj hmo ntuj lossis lub sijhawm tos tos:
Lub roj teeb yog siv los xyuas kom meej lub zog ib txwm siv ntawm lub cev thauj khoom thaum lub hnub ci hluav taws xob tsis txaus, thaum hmo ntuj lossis hnub los nag tas mus li.Rau qhov tsim nyog nyob load, kev ua haujlwm ntawm lub cev tuaj yeem lav tsis pub dhau ob peb hnub.Piv nrog rau cov neeg siv zoo tib yam, nws yog ib qho tsim nyog yuav tau xav txog qhov kev daws teeb meem zoo.
(1) Sim xaiv cov khoom siv txuag hluav taws xob, xws li LED teeb, inverter cua txias;
(2) Nws tuaj yeem siv tau ntau dua thaum lub teeb pom kev zoo.Nws yuav tsum tau siv me ntsis thaum lub teeb tsis zoo;
(3) Hauv kev tsim hluav taws xob photovoltaic, feem ntau ntawm cov roj teeb gel yog siv.Xav txog lub neej ntawm lub roj teeb, qhov tob ntawm kev tso tawm feem ntau ntawm 0.5-0.7.
Tsim lub peev xwm ntawm lub roj teeb = (qhov nruab nrab txhua hnub siv hluav taws xob ntawm kev thauj khoom * tus naj npawb ntawm cov huab cua sib law liag thiab los nag) / qhov tob ntawm cov roj teeb tawm.
1. Cov xwm txheej huab cua thiab nruab nrab hnub ci hnub ci cov ntaub ntawv ntawm thaj chaw siv;
2. Lub npe, lub zog, qhov ntau, cov sij hawm ua haujlwm, cov sij hawm ua hauj lwm thiab qhov nruab nrab ntawm cov khoom siv hluav taws xob niaj hnub siv;
3. Nyob rau hauv cov xwm txheej ntawm lub peev xwm ntawm lub roj teeb, cov khoom siv hluav taws xob xav tau rau cov huab cua sib law liag thiab los nag;
4. Lwm yam kev xav tau ntawm cov neeg siv khoom.
Cov khoom siv hnub ci ntawm lub hnub ci tau teeb tsa rau ntawm lub bracket los ntawm kev sib xyaw ua ke ua ke los tsim ib lub hnub ci cell array.Thaum lub hnub ci cell module ua haujlwm, cov kev taw qhia kev teeb tsa yuav tsum xyuas kom muaj hnub ci siab tshaj plaws.
Azimuth yog hais txog lub kaum sab xis ntawm qhov ib txwm mus rau ntsug saum npoo ntawm cov khoom thiab sab qab teb, uas feem ntau yog xoom.Modules yuav tsum tau nruab rau ntawm ib qho inclination mus rau txoj kab nruab nrab.Ntawd yog, modules nyob rau sab qaum teb hemisphere yuav tsum tig mus rau sab qab teb, thiab cov modules nyob rau sab qab teb hemisphere yuav tsum tig mus rau sab qaum teb.
Lub kaum sab xis yog hais txog lub kaum sab xis ntawm sab pem hauv ntej ntawm lub module thiab lub dav hlau kab rov tav, thiab qhov luaj li cas ntawm lub kaum sab xis yuav tsum tau txiav txim siab raws li hauv zos latitude.
Lub peev xwm tu tus kheej ntawm lub hnub ci vaj huam sib luag yuav tsum raug txiav txim siab thaum lub sijhawm teeb tsa tiag tiag (feem ntau, lub kaum sab xis inclination ntau dua 25 °).
Kev ua tau zoo ntawm lub hnub ci hlwb ntawm ntau lub kaum sab xis installation:
Cov kev ceev faj:
1. Xaiv qhov chaw teeb tsa thiab teeb tsa lub kaum sab xis ntawm lub hnub ci cell module;
2. Nyob rau hauv cov txheej txheem ntawm kev thauj mus los, kev cia khoom thiab kev teeb tsa, lub hnub ci modules yuav tsum tau ua tib zoo saib xyuas, thiab yuav tsum tsis txhob muab tso rau hauv qhov hnyav thiab kev sib tsoo;
3. Lub hnub ci cell module yuav tsum nyob ze li sai tau rau cov tswj inverter thiab roj teeb, ua kom cov kab nrug deb npaum li sai tau, thiab txo cov kab poob;
4. Thaum lub sij hawm installation, xyuam xim rau qhov zoo thiab tsis zoo tso zis terminals ntawm lub tivthaiv, thiab tsis txhob luv luv Circuit Court, txwv tsis pub nws yuav ua rau muaj kev pheej hmoo;
5. Thaum txhim kho lub hnub ci modules nyob rau hauv lub hnub, npog cov modules nrog opaque cov ntaub ntawv xws li dub yas zaj duab xis thiab wrapping ntawv, kom tsis txhob muaj kev txaus ntshai ntawm high tso zis voltage cuam tshuam rau kev twb kev txuas ua hauj lwm los yog ua rau hluav taws xob poob rau cov neeg ua hauj lwm;
6. Xyuas kom tseeb tias cov txheej txheem thaiv kab thiab kev teeb tsa raug raug.
