Photovoltaic inverter (tseem hu ua hnub ci inverter) yog cov khoom siv hloov pauv tseem ceeb hauv kev tsim hluav taws xob photovoltaic, hu ua "lub plawv" ntawm photovoltaic system. Nws yog lub luag haujlwm tseem ceeb rau kev hloov pauv qhov hloov pauv DC voltage tsim los ntawm photovoltaic hnub ci vaj huam sib luag rau hauv AC lub zog uas ua tau raws li qhov zaus ntawm daim phiaj lossis cov khoom siv hluav taws xob xav tau. Nws yog ib qho tseem ceeb hub txuas photovoltaic modules nrog rau daim phiaj thiab cov khoom siv hluav taws xob.
Raws li ib qho tseem ceeb ntawm photovoltaic array system tshuav nyiaj li cas (BOS), photovoltaic inverters tsis tsuas yog ua lub luag haujlwm tseem ceeb ntawm lub zog hloov pauv, tab sis kuj muaj cov haujlwm tshwj xeeb los hloov kho rau cov tshuab photovoltaic. Ntawm lawv, qhov siab tshaj plaws lub zog taw tes nrhiav (MPPT) thev naus laus zis yog ib qho ntawm nws cov txiaj ntsig tseem ceeb, uas tuaj yeem taug qab tiag tiag - lub sijhawm hloov pauv hauv hnub ci irradiance, ib puag ncig kub, thiab tag nrho cov kev tiv thaiv ntawm lub hnub ci, dynamically kho qhov ua haujlwm tsis zoo, tshem tawm lub zog siab tshaj plaws los ntawm photovoltaic vaj huam sib luag, thiab txhim kho photovoltaic zog tsim efficiency.
Tsis tas li ntawd, lub photovoltaic inverter kuj tau nruab nrog kev tiv thaiv kev tiv thaiv kev tiv thaiv kev ua haujlwm, uas tuaj yeem zam qhov tsim ntawm "Islanding" thaum lub photovoltaic system muab lub zog sib cais thaum lub hwj chim daim phiaj cuam tshuam, ua kom muaj kev ruaj ntseg ntawm daim phiaj hluav taws xob tu cov neeg ua haujlwm thiab cov cuab yeej ruaj ntseg. Nws muaj ntau yam ntawm daim ntawv thov scenarios, uas tsis tau tsuas yog xa cov converted AC fais fab rov qab mus rau lub lag luam sib kis daim phiaj, tab sis kuj ua tiav photovoltaic fais fab sib txuas; Nws tseem tuaj yeem muab cov kab hluav taws xob tawm los muab lub zog ruaj khov rau thaj chaw deb, cov khoom siv sab nraum zoov, thiab lwm yam, thiab tuaj yeem siv ncaj qha nrog rau cov khoom siv hluav taws xob AC.
Nrog kev txhim kho txuas ntxiv ntawm kev tsim hluav taws xob photovoltaic thev naus laus zis, photovoltaic inverters tau kho dua tshiab ntawm kev ua haujlwm siab, miniaturization, thiab kev txawj ntse. Qhov no tsis yog tsuas yog txhim kho kev hloov pauv hluav taws xob, tab sis kuj ua kom zoo rau kev ua haujlwm thiab kev saib xyuas yooj yim, muab kev txhawb nqa tseem ceeb rau kev loj hlob ntawm -scale kev lag luam thoob ntiaj teb photovoltaic. Nws yog ib qho ntawm cov cuab yeej tseem ceeb rau kev ua tiav kev hloov hluav taws xob huv thiab txhawb nqa lub hom phiaj "dual carbon".
