Nyob rau hauv xyoo tas los no, lub hnub ci zog tau txais kev muaj koob meej raws li lub zog huv, rov ua dua tshiab. Raws li ntau thiab ntau tus neeg thiab cov lag luam tig mus rau lub hnub ci zog, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus tseem ceeb ntawm lub hnub ci. Ib qho ntawm cov khoom tseem ceeb yog lub hnub ci inverter. Hauv tsab xov xwm no, peb yuav tshawb txog kev ua haujlwm ntawm lub hnub ci inverter hauv lub hnub ci thiab nws qhov tseem ceeb hauv kev hloov hnub ci zog rau hauv hluav taws xob siv tau.
Lub hnub ci inverter, tseem hu ua photovoltaic inverter, yog ib qho khoom siv hluav taws xob hloov hluav taws xob tam sim no (DC) tsim los ntawm lub hnub ci vaj huam sib luag rau hauv alternating tam sim no (AC). Qhov kev hloov pauv no yog qhov tsim nyog vim tias feem ntau cov khoom siv hauv tsev thiab cov kab hluav taws xob khiav ntawm AC lub zog. Yog li ntawd, hnub ci inverters ua lub luag haujlwm tseem ceeb hauv kev ua lub hnub ci zog muaj txiaj ntsig zoo rau kev siv niaj hnub.
Lub luag haujlwm tseem ceeb ntawm lub hnub ci inverter yog txhawm rau txhim kho kev ua haujlwm ntawm lub hnub ci vaj huam sib luag thiab xyuas kom muaj lub zog siab tshaj plaws. Hnub ci vaj huam sib luag tsim hluav taws xob ncaj qha thaum raug tshav ntuj. Txawm li cas los xij, DC no tsis haum rau kev siv hluav taws xob hauv tsev lossis pub rau hauv kab sib chaws. Hnub ci inverters daws qhov teeb meem no los ntawm kev hloov DC lub zog rau hauv AC lub zog, uas tuaj yeem siv rau lub zog hauv tsev, kev lag luam, lossis txawm tias tag nrho cov zej zog.
Lwm txoj haujlwm tseem ceeb ntawm lub hnub ci inverter yog saib xyuas thiab tswj cov dej ntws ntawm hluav taws xob hauv lub hnub ci. Nws ua raws li lub hlwb ntawm lub system, tas li saib xyuas qhov voltage, tam sim no thiab zaus ntawm cov hluav taws xob generated. Qhov kev soj ntsuam no tso cai rau lub inverter kom ntseeg tau tias cov hnub ci vaj huam sib luag ua haujlwm ntawm qhov ua tau zoo tshaj plaws thiab lub zog tsim tau ruaj khov thiab nyab xeeb.
Tsis tas li ntawd, hnub ci inverters tau nruab nrog cov yam ntxwv siab heev uas txhim kho kev ua haujlwm tag nrho thiab kev nyab xeeb ntawm koj lub hnub ci. Ib qho zoo li no yog Kev Tshaj Tawm Tshaj Tawm Tshaj Tawm (MPPT), uas ua kom zoo dua lub zog hluav taws xob ntawm lub hnub ci vaj huam sib luag los ntawm kev hloov kho qhov hluav taws xob thiab qib tam sim no. MPPT xyuas kom meej tias lub hnub ci vaj huam sib luag ib txwm ua haujlwm ntawm lawv cov hluav taws xob siab tshaj plaws, txawm tias nyob hauv huab cua sib txawv.
Tsis tas li ntawd, hnub ci inverters ua lub luag haujlwm tseem ceeb hauv daim phiaj-txuas hnub ci. Hauv cov tshuab no, lub zog ntau dhau los ntawm cov hnub ci vaj huam sib luag tuaj yeem muab rov qab rau hauv daim phiaj, tau txais cov qhab nia lossis txo nqi hluav taws xob. Hnub ci inverters pab txhawb cov txheej txheem no los ntawm synchronizing lub alternating tam sim no uas tsim los ntawm lub hnub ci panels nrog rau qhov voltage thiab zaus ntawm daim phiaj. Nws ua kom ntseeg tau tias lub zog pub rau hauv daim phiaj yog synchronized nrog cov khoom siv loj, tso cai rau lub hnub ci zog kom ua haujlwm zoo rau hauv cov khoom siv hluav taws xob uas twb muaj lawm.
Lub hnub ci inverter yog ib feem tseem ceeb ntawm lub hnub ci system. Nws lub luag haujlwm tseem ceeb yog hloov DC lub zog tsim los ntawm lub hnub ci vaj huam sib luag rau hauv AC lub zog rau kev siv txhua hnub. Tsis tas li ntawd, hnub ci inverters tseem saib xyuas thiab tswj qhov ntws ntawm cov tam sim no nyob rau hauv lub system, optimize cov kev ua tau zoo ntawm lub hnub ci vaj huam sib luag, thiab xyuas kom meej muaj kev ruaj ntseg thiab stability ntawm lub hwj chim tiam. Nrog cov yam ntxwv siab heev xws li MPPT thiab daim phiaj kev sib txuas muaj peev xwm, hnub ci inverters ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo tshaj plaws thiab kev sib koom ua ke hnub ci zog rau hauv peb lub zog. Raws li qhov kev thov rau lub zog huv thiab txuas ntxiv txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm lub hnub ci inverters hauv kev siv lub zog ntawm lub hnub tsis tuaj yeem overstated.
