Cheebtsam ntawm photovoltaic system
1.PV system Cheebtsam PV system muaj cov nram qab no tseem ceeb qhov chaw.Photovoltaic modules yog tsim los ntawm photovoltaic hlwb rau hauv nyias zaj duab xis panels muab tso rau ntawm lub encapsulation txheej.Inverter yog thim rov qab DC lub zog tsim los ntawm PV module rau hauv kab sib txuas AC fais fab.Lub roj teeb yog cov cuab yeej uas khaws cov khoom siv hluav taws xob ncaj qha (DC) lub zog.Photovoltaic mounts muab kev txhawb nqa rau qhov chaw PV modules.
2. Hom PV tshuab tuaj yeem muab faib ua ob hom.Grid-connected system: qhov zoo ntawm hom kab ke no yog tias tsis muaj roj teeb cia, txuas ncaj qha rau hauv lub teb chaws daim phiaj, tsis tas yuav txhawj txog hluav taws xob;off-grid system: off-grid system xav tau lub roj teeb los khaws lub zog, yog li tus nqi yuav raug siab.
Piv txwv ntawm kab hluav taws xob sib txuas thiab off-grid systems tau qhia hauv kev sib piv:
Photovoltaic system thaiv:
1. PV system series-parallel kev twb kev txuas PV modules tuaj yeem txuas rau hauv kev sib txuas lossis hauv series raws li qhov yuav tsum tau ua, thiab tseem tuaj yeem txuas nrog cov sib xyaw ua ke.Piv txwv li, 4 12V PV modules yog siv los tsim 24V off-grid system: 16 34V PV modules yog siv los tsim cov kab sib txuas uas muaj ob ntu.
2. Txuas cov khoom siv rau inverter qauv.Tus naj npawb ntawm cov khoom uas tuaj yeem ua khub rau ntau yam qauv ntawm inverters yog qhov tseeb, thiab tus naj npawb ntawm cov kev sib txuas rau txhua pawg ntawm cov khoom tuaj yeem faib raws li tus naj npawb ntawm inverter ceg, raws li qhia hauv daim duab:
3. Inverter kev twb kev txuas txoj kev DC Circuit Court breaker thiab AC Circuit Court breaker yuav tsum tau ntsia ntawm DC input thiab AC tso zis ntawm lub inverter feem.Yog hais tias muaj ntau tshaj ib pab pawg ntawm inverters yuav tsum tau txuas rau tib lub sij hawm, lub DC davhlau ya nyob twg ntawm txhua pab pawg ntawm inverters yuav tsum tau txuas mus rau lub module cais, thiab AC davhlau ya nyob twg yuav tsum tau txuas nrog rau daim phiaj nyob rau hauv parallel, thiab lub cable txoj kab uas hla. yuav tsum tau thickened raws li.
4. AC davhlau ya nyob twg daim phiaj sib txuas feem ntau txuas nrog daim phiaj los ntawm lub tuam txhab muab hluav taws xob, lub chaw teeb tsa tsuas yog xav tau tshwj xeeb AC davhlau ya nyob twg hauv lub thawv ntsuas, thiab nruab qhov hloov pauv.Yog tias tus tswv tsis siv daim phiaj lossis tsis tau txais kev pom zoo rau kev sib txuas ntawm daim phiaj.Tom qab ntawd lub installation yuav tsum txuas rau AC kawg ntawm qis kawg ntawm lub hwj chim inlet hloov.Tus neeg siv yuav xav tau peb-theem inverter yog tias nws txuas nrog peb-theem fais fab.
Bracket ntu:
Lub bracket ntawm cement ca ru tsev cement ca ru tsev tuaj yeem muab faib ua ob ntu, ib qho yog lub hauv paus ntawm lub bracket thiab lwm qhov yog lub bracket.Lub hauv paus ntawm lub bracket yog ua los ntawm pob zeb nrog tus qauv C30.Cov brackets tsim los ntawm cov tuam txhab sib txawv yog qhov sib txawv, thiab cov cuab yeej siv tau sib txawv raws li qhov tshwj xeeb ntawm qhov chaw.Ua ntej tshaj plaws, nws yog qhov yooj yim kom nkag siab txog cov khoom siv sib txuas thiab cov duab ntawm txhua feem rau kev teeb tsa ceev ntawm cov brackets.
