Yog tias koj xav sim koj txhais tes ntawm DIY hnub ci, qhov me me off-grid system muaj kev nyab xeeb thiab yooj yim rau nruab dua li lub ru tsev tag nrhohnub ci system.Hauv ntau qhov chaw, kev txhim kho thiab txuas lub hnub ci rau hauv kab sib chaws yuav tsum muaj ntawv tso cai lossis ntawv pov thawj.Thiab, raws li peb tau hais hauv peb tsab xov xwm dhau los, ntau lub xeev txwv tsis pub cov neeg nyob hauv kev sib txuas ntawm DIY system mus rau daim phiaj hluav taws xob.Tab sis kev tsim ib qho me me off-grid system tuaj yeem ua tau yooj yim xav tsis thoob.Txhua yam koj xav tau yog qee qhov kev suav yooj yim thiab kev paub txog hluav taws xob yooj yim.
Cia peb mus saib yuav ua li cas npaj, tsim, thiab nruab ib lub hnub ci hluav taws xob off-grid.
Cov cuab yeej thiab cov cuab yeej xav tau rau DIY Solar System
Ua ntej peb tham txog kev txhim kho, ntawm no yog cov npe ntawm cov cuab yeej thiab cov cuab yeej koj yuav xav tau:
- Hnub ci vaj huam sib luag:Thawj thiab pom tseeb yam khoom koj yuav xav tau yog lub hnub ci vaj huam sib luag.Panels yog lub zog tsim ib feem ntawm qhov system.
- Inverter: Ib qho inverter converts ncaj qha tam sim no (DC) los ntawm cov vaj huam sib luag rau hauv usable, alternating tam sim no (AC).Cov khoom siv niaj hnub no feem ntau ua haujlwm ntawm AC lub zog, tshwj tsis yog koj xaiv siv cov khoom siv DC rau koj lub cev.
- Roj teeb:Lub roj teeb khaws lub zog ntau dhau thaum nruab hnub thiab muab khoom siv thaum hmo ntuj - yog ib txoj haujlwm tseem ceeb txij li hnub ci vaj huam sib luag tsis ua haujlwm tom qab hnub poob.
- Charger tswj:Tus tswj kev them nqi txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm lub roj teeb lub roj teeb.
- Kev xaim:Ib txheej ntawm cov xov hlau yuav tsum tau txuas mus rau tag nrho cov txheej txheem system.
- Mounting racks:Txawm hais tias xaiv tau, mounting racks yog qhov tseem ceeb rau kev tso lub hnub ci vaj huam sib luag ntawm lub kaum sab xis rau kev tsim hluav taws xob.
- Lwm yam khoom:Ntxiv nrog rau cov khoom tseem ceeb uas tau teev tseg saum toj no, koj yuav xav tau cov khoom hauv qab no los ua kom tiav qhov system:
fuses / breakers
Cov khoom sib txuas (nco ntsoov tias ntau cov khoom siv niaj hnub no tuaj nrog cov khoom sib txuas)
Cov kab mob
Metering ntaus ntawv (yeem)
Terminal lugs
- Cov cuab yeej:Koj tseem yuav xav tau qee cov cuab yeej siv yooj yim rau nruab qhov system.
Hlau stripper
Crimping cuab tam
Pliers
Screwdriver
Wrenches
Yuav Ua Li Cas Tsim Lub Hnub Ci Hluav Taws Xob
Tsim lub hnub ci fais fab system txhais tau tias txiav txim siab qhov loj ntawm qhov system koj xav tau.Qhov loj me no feem ntau yog nyob ntawm tag nrho cov kev xav tau hluav taws xob ntawm tag nrho cov khoom siv uas lub kaw lus yuav siv hluav taws xob.
Ua li no, sau tag nrho koj cov khoom siv thiab lawv lub zog (teev teev) thiab lub zog (txhua hnub) noj.Qhov ntsuas hluav taws xob ntawm txhua lub cuab yeej yog muab nyob rau hauv watts (W), thiab feem ntau sau tseg ntawm cov khoom siv.Koj tseem tuaj yeem siv cov cuab yeej hauv online kom paub seb lub zog siv ntawm koj cov khoom siv.
Xam cov kev siv hluav taws xob los ntawm kev siv hluav taws xob ntau los ntawm cov sij hawm siv.Thaum koj paub qhov ntsuas hluav taws xob ntawm txhua yam khoom siv uas koj npaj yuav khiav ntawm hnub ci, ua ib lub rooj nrog lub zog thiab lub zog muaj nuj nqis.
Sizing lubHnub Ci Vaj Huam Sib Luag
Txhawm rau loj koj lub hnub ci vaj huam sib luag, pib los ntawm kev tshawb nrhiav qhov nruab nrab hnub ci teev hauv koj qhov chaw.Koj tuaj yeem nrhiav lub hnub ci txhua hnub rau txhua qhov chaw los ntawm ib qho ntawm ntau qhov chaw hauv internet.Thaum koj muaj tus lej ntawd, hauv qab no yog qhov yooj yim xam kom paub seb lub hnub ci vaj huam sib luag loj.
Tag nrho lub zog xav tau (Wh) ÷ hnub ci hnub ci teev (h) = hnub ci vaj huam sib luag loj (W)
Sizing lubRoj teebthiab Charge Controller
Feem ntau cov tuam txhab tam sim no muab cov roj teeb uas teev hauv Wh lossis kWh.Rau cov ntaub ntawv thauj khoom hauv peb qhov piv txwv saum toj no, lub roj teeb yuav tsum tuaj yeem khaws qhov tsawg kawg nkaus ntawm 2.74 kWh.Ntxiv qee qhov kev nyab xeeb rau qhov no, thiab peb tuaj yeem siv lub roj teeb txhim khu kev qha ntawm 3 kWh.
Xaiv tus nqi tswj hwm zoo ib yam.Saib rau tus nqi tswj hwm nrog qhov ntsuas hluav taws xob uas phim lub vaj huam sib luag thiab roj teeb hluav taws xob (xws li 12 V).Txheeb xyuas cov kev tswj xyuas tshwj xeeb kom ntseeg tau tias nws lub peev xwm tam sim no siab dua qhov ntsuas tam sim no ntawm cov hnub ci vaj huam sib luag (xws li, siv 20A maub los rau 11A hnub ci vaj huam sib luag).
Xaiv lub Inverter
Koj qhov kev xaiv inverter nyob ntawm qhov ntsuas ntawm koj lub roj teeb thiab lub hnub ci vaj huam sib luag.Xaiv lub inverter nrog lub zog ntsuas me ntsis siab dua koj cov panels.Hauv qhov piv txwv saum toj no, peb muaj 750 W panels thiab tuaj yeem siv 1,000 W inverter.
Tom ntej no, xyuas kom meej tias lub inverter's PV input voltage sib phim qhov voltage ntawm lub hnub ci vaj huam sib luag (piv txwv li, 36 V), thiab lub roj teeb input voltage phim qhov ntsuas hluav taws xob ntawm koj lub roj teeb (xws li, 12 V).
Koj tuaj yeem yuav lub inverter nrog cov chaw nres nkoj sib xyaw thiab txuas koj cov khoom siv ncaj qha rau lub inverter, kom yooj yim siv.
Xaiv txoj cai Cable Sizes
Rau cov tshuab me me xws li ib qho peb tab tom tsim, cable loj tsis yog ib qho kev txhawj xeeb loj.Koj tuaj yeem xaiv siv dav dav, 4 mm cable rau tag nrho koj cov kev sib txuas.
Rau cov tshuab loj, qhov loj me me yog qhov tseem ceeb los xyuas kom muaj kev nyab xeeb thiab ua haujlwm zoo.Nyob rau hauv tas li ntawd, nco ntsoov siv ib tug online cable loj qhia.
Txhim kho qhov System
Los ntawm qhov no, koj yuav muaj tag nrho cov khoom siv kom raug.Qhov no coj koj mus rau theem kawg - installation.Kev txhim kho lub hnub ci zog tsis yog qhov nyuaj.Cov khoom siv niaj hnub no feem ntau tuaj nrog cov chaw nres nkoj npaj txhij thiab cov khoom sib txuas yog li nws yooj yim los txuas cov khoom.
Thaum txuas cov khoom sib txuas, ua raws li daim duab qhia hauv qab no.Qhov no yuav ua kom ntseeg tau tias lub zog ntws mus rau qhov tseeb thiab kev coj ua.
Kev xav zaum kawg
Mus hnub ci tsis tau txhais hais tias koj yuav tsum ntiav ib pab neeg thiab siv ntau txhiab.Yog tias koj tab tom txhim kho qhov yooj yim, me me off-grid unit, koj tuaj yeem ua koj tus kheej nrog me ntsis kev ua lej thiab qee qhov kev paub txog hluav taws xob.
Xwb, koj tuaj yeem xaiv lub hnub ci hluav taws xob portable, uas siv cov cuab yeej sib txuas nrog lub roj teeb, inverter, thiab lwm yam khoom siv hluav taws xob rau hauv ib chav tsev.Txhua yam koj yuav tau ua yog ntsaws koj lub hnub ci vaj huam sib luag rau hauv nws.Qhov kev xaiv no yog me ntsis kim dua, tab sis kuj yog qhov yooj yim tshaj plaws.
