Txij li thaum lub hom phiaj ntawm "dual carbon" tau teeb tsa, kev faib tawm photovoltaic tau txais kev pom zoo rau nws qhov zoo ntawm cov pa roj carbon emission txo qis, ntau yam kev thov cov xwm txheej thiab yooj yim rov qab los ntawm kev nqis peev.Txawm li cas los xij, nrog kev nce nrawm ntawm lub peev xwm, kuj tseem muaj ntau qhov kev mob tshwm sim hauv kev ua lag luam, xws li DC high voltage, chim nyhuv, kev khiav hauj lwm thiab txij nkawm nyuaj ...... Qhov no ua rau muaj kev txhawj xeeb txog kev ruaj ntseg thiab tsis xav tau. rov qab los ntawm kev nqis peev rau cov neeg siv kawg.
Rau cov ntsiab lus mob saum toj no, Wo Mai micro inverter tuaj yeem daws tau yooj yim.Tam sim no, peb muab cov kev lag luam teeb meem tam sim no, kev tsom xam qhov tob ntawm Wo Mai micro inverse tov, kom paub.
01
Kev lag luam mob taw tes #1: Kev ruaj ntseg
Nyob rau hauv xyoo tas los no, tsev neeg hluav taws xob photovoltaic yog nquag, 80% ntawm uas yog tshwm sim los ntawm DC arc tshwm sim los ntawm ib txwm inverter DC high voltage.Ntxiv mus, xws li photovoltaic systems feem ntau yog ntsia rau ntawm lub ru tsev ntawm cov tsev los yog factories.Thaum hluav taws kub lossis tawg tshwm sim, nws yuav ua rau muaj kev puas tsuaj loj heev thiab ua rau muaj kev phom sij rau lub neej.
Tsis tas li ntawd, tseem muaj ntau pua lossis ntau txhiab volts ntawm DC nyob rau hauv lub combustion system.Yog tias cov neeg tua hluav taws maj nrawm rau kev cawm, nws tuaj yeem ua rau muaj kev ntxhov siab.Yog li ntawd, thawj cov neeg teb feem ntau yuav tsum tau tos kom cov nroj tsuag hlawv tag ua ntej lawv tuaj yeem pib ua haujlwm, uas feem ntau ua rau muaj kev cuam tshuam loj hauv kev tua hluav taws.
Tswv yim 1
Tsawg voltage kev nyab xeeb, tsis muaj hluav taws kub txaus ntshai thiab hluav taws xob poob siab
Hemai micro inverter txuas nrog lub photovoltaic system nyob rau hauv parallel, ua rau DC sab ntawm lub kaw lus ruaj khov ntawm li 40V tsis tshua muaj hluav taws xob, los ntawm cov hauv paus hniav kom tshem tawm cov hluav taws kub thiab hluav taws xob poob siab.Peb tsis tas yuav txhawj xeeb txog DC arc hluav taws ntawm micro-retrograde fais fab nroj tsuag.
Txawm hais tias lub micro inverter system muaj qhov xwm txheej ceev vim yog lwm yam, tom qab kaw lub kaw lus, thawj cov neeg teb yuav tsis ntsib kev pheej hmoo ntawm hluav taws xob poob vim tias tsis muaj DC high voltage hauv PV cog.
02
Kev lag luam mob taw tes 2: cov nyhuv chim
Txhua lub vaj huam sib luag photovoltaic muaj cov yam ntxwv sib txawv, xws li tam sim no, qhov hluav taws xob thiab qhov ua haujlwm zoo tshaj plaws.Qhov kev tsis sib haum no yuav pom meej dua vim tias cov tshuab photovoltaic siv sab nraum zoov ntev thiab muaj hnub nyoog ib txwm muaj.Lub zog tsim cov yam ntxwv ntawm cov tsoos photovoltaic system yog zoo ib yam li "ntoo chim nyhuv": cov tsoos photovoltaic system yog tsim nyob rau hauv series, thiab tag nrho cov tsim hluav taws xob ntawm ib tug series ntawm photovoltaic panels nyob ntawm ntau yam ntawm cov zis cov yam ntxwv ntawm lub weakest photovoltaic. vaj huam sib luag hauv koob, uas txhais tau hais tias "tsis muaj zog" yuav luag rub pab pawg thiab cuam tshuam rau cov nyiaj tau los ntawm lub zog.
Kev xaiv 2
Component-theem MPPT thev naus laus zis tshem tawm cov nyhuv chim
Hauv kev pom ntawm "cov nyhuv cask", Wo Mai micro rov qab tshuaj.Nws cov khoom-theem MPPT maub los taug qab lub zog siab tshaj plaws ntawm txhua PV module cais.Txawm hais tias ib qho PV module tsis ua haujlwm tau zoo, nws yuav tsis cuam tshuam rau lwm cov PV modules.Piv txwv li, nyob rau hauv tag nrho photovoltaic system, yog hais tias ib tug tivthaiv puas los yog thaiv, lub siab tshaj plaws lub hwj chim taw tes mus txog qhovtwg maub los ntawm lwm yam Cheebtsam yuav txuas ntxiv tswj lawv lub peev xwm siab tshaj plaws efficiency.
