Lub inverter yog lub converter uas hloov DC lub zog rau hauv qhov chaw ruaj khov, qhov tsis tu ncua-voltage lossis zaus-tswj thiab voltage-regulated alternating tam sim no, uas yog, DC rau AC. Lub hwj chim adapter ntawm ib qho khoom siv hluav taws xob yog lub converter uas hloov pauv tam sim no los ntawm daim phiaj hluav taws xob mus rau tam sim no ncaj qha, AC rau DC, siv los ntawm cov khoom siv hauv tsev. Lub inverter ua hauj lwm nyob rau hauv lub opposite kev taw qhia thiab yog ib tug txheej txheem ntawm voltage inversion, li no nws lub npe.
Lub inverter nyob rau hauv lub photovoltaic system converts ncaj qha tam sim no generated los ntawm photovoltaic panels mus rau hauv alternating tam sim no, thiaj li hais tias nws yuav tsum tau txuas nrog rau daim phiaj thiab cov hluav taws xob xa tawm mus rau hauv daim phiaj muag nyiaj.
Lub tshuab hluav taws xob photovoltaic txuas nrog lub tshuab hluav taws xob feem ntau yog cov khoom siv hluav taws xob photovoltaic, cov thawv sib txuas, kab sib txuas sib txuas inverters, cov kauj ruam-up transformers, thiab lwm yam. Lub thawv sib xyaw ua ke ua ke nrog DC lub zog tawm los ntawm photovoltaic array. Lub inverter hloov lub zog DC rau hauv sine yoj tam sim no nrog tib zaus thiab tswj tau theem amplitude li daim phiaj. Thaum kawg, lub transformer phim cov kab hluav taws xob hluav taws xob thiab tawm mus rau Grid.
Inverters hauv photovoltaic zog tsim tshuab
Ntxiv nrog rau kev hloov DC rau AC, inverters hauv photovoltaics tam sim no kuj muaj lwm yam haujlwm tseem ceeb. Piv txwv li, kev ua haujlwm tsis siv neeg thiab kaw, kev tswj xyuas lub zog siab tshaj plaws, kev tiv thaiv kev ua haujlwm ywj pheej, tsis siv neeg hloov hluav taws xob, DC nrhiav kom pom muaj nuj nqi, DC hauv av nrhiav kom muaj nuj nqi, thiab lwm yam tuaj yeem ua kom lub hnub ci ua haujlwm zoo tshaj plaws thiab tiv thaiv kev ua haujlwm tsis zoo.
Thaum lub hnub tawm los thaum sawv ntxov, qhov kev siv ntawm lub hnub ci maj mam nce, thiab cov khoom tsim tawm ntawm photovoltaic panels kuj maj mam nce. Thaum cov zis hluav taws xob xav tau rau lub inverter mus txog, lub inverter pib ua haujlwm tau txais. Lub inverter yuav ib txwm nias qhov tso zis ntawm cov khoom siv roj teeb thiab txuas ntxiv mus; Thaum lub hnub poob los yog huab cua tsaus, qhov tso zis ntawm cov khoom siv roj teeb ua me me thiab cov zis inverter ze rau 0, lub inverter cia li nkag mus rau hauv lub xeev standby.
Kev hloov pauv ntawm photovoltaic inverter yog hais txog qhov ua tau zoo uas lub inverter hloov cov hluav taws xob tawm los ntawm lub vaj huam sib luag photovoltaic rau hauv hluav taws xob. Qhov siab dua qhov kev hloov pauv ntawm lub inverter, qhov hluav taws xob ntau dua tuaj yeem siv lossis muag hauv tsev, thiab cov nyiaj tau los yuav ntau dua.
Muaj ntau hom photovoltaic inverters
Independent inverter: Ib qho inverter txuas nrog cov txheej txheem photovoltaic, tsim rau cov tshuab hluav taws xob me me thiab nruab nrab.
Central inverter: Ib tug loj inverter txuas nrog nyob rau hauv series thiab parallel nrog ntau pawg ntawm photovoltaic panels. Nws yog tsim rau loj-scale photovoltaic zog tsim tshuab thiab muaj qhov zoo ntawm centralized saib xyuas thiab tswj.
Microinverter: Txhua lub vaj huam sib luag photovoltaic yog nruab nrog lub microinverter, uas ua haujlwm ntawm nws tus kheej thiab tsim nyog rau cov xwm txheej uas lub zog tsim hluav taws xob thiab kev hloov pauv yuav tsum tau ua kom zoo.
Lub luag haujlwm ntawm inverters hauv kev lag luam photovoltaic
Hauv kev tsim hluav taws xob photovoltaic, lub inverter yog ib qho ntawm cov cores tseem ceeb. R & D thiab tsim cov inverters kuj tseem ceeb txuas hauv kev lag luam photovoltaic saw.
Txoj kev loj hlob ntawm kev lag luam photovoltaic txuas ntxiv muab cov kev cai tshiab rau cov cuab yeej siv tshuab. Hauv 10 xyoo dhau los, inverter thev naus laus zis tau txuas ntxiv tsim kho tshiab, los ntawm kev ua tsis tiav siab mus rau kev ntseeg siab, thiab los ntawm cov nqi zog siab rau kev ua haujlwm ntse thiab kev saib xyuas, uas tau txhawb nqa txoj kev loj hlob zoo ntawm kev lag luam photovoltaic.
Lub tsheb tuaj yeem siv lub inverter los txuas lub roj teeb kom tsav cov khoom siv hluav taws xob ua haujlwm. Lub tsheb inverters tso zis los ntawm cov luam yeeb teeb muaj lub zog tshwj xeeb ntawm 20W, 40W, 80W, 120W txog 150W. Cov khoom siv hluav taws xob siab dua inverter yuav tsum tau txuas nrog lub roj teeb los ntawm kev sib txuas ntawm cov xov hlau. Los ntawm kev sib txuas cov khoom siv hauv tsev rau cov khoom siv hluav taws xob hloov hluav taws xob, ntau yam khoom siv tuaj yeem siv hauv lub tsheb.
