Kev kawm paub cov ntaub ntawv los ntawm cov ntsiab lus dhau los yog qhov tsim nyog ua ntej txiav txim siab yuav lub hnub ci tus nqi tswj rau koj lub PV system. Ib lub rooj sib piv, teev qhov sib txawv ntawm PWM thiab MPPT, kuj tau qhia. Yog li, peb muab lawv qhov zoo thiab qhov tsis zoo ua ke los ua kom yooj yim dua rau koj los tshuaj xyuas.
ProsConsPWM
PWM thev naus laus zis tau muaj nyob rau hauv PV systems tau ntev thiab yog ib qho kev ruaj khov thiab paub tab technology
Lawv yog cov nqi-zoo thiab pheej yig rau cov neeg siv khoom feem ntau
PWM tuaj yeem tiv taus txog 60 amps load tam sim no
Feem ntau PWMs muaj cov qauv hluav taws xob tsim nyog uas tso cai rau lawv ua haujlwm tsis tu ncua
PWM los ntawm ntau qhov sib txawv kom haum rau ntau yam kev siv
Yog tias PWM siv rau cov tshuab hluav taws xob photovoltaic, qhov hluav taws xob ntawm lub hnub ci vaj huam sib luag yuav tsum sib npaug ntawm lub txhab nyiaj roj teeb.
Lub peev xwm thauj khoom tam sim no ntawm ib qho PWM tsis tau tsim thiab tseem tsuas yog nce txog 60 amps
Qee qhov me me PWM tus nqi tswj tsis tuaj yeem yog UL teev vim lawv cov qauv tsim tsis zoo
Qee qhov me me PWM tsis muaj fittings ntawm cov kav dej
PWM muaj teeb meem cuam tshuam qee zaum. Cov tswj ua suab nrov hauv TV lossis xov tooj cua
PWM txwv kev nthuav dav ntawm photovoltaic solar systems rau qee qhov
Nws tsis tuaj yeem siv rau high voltage off-grid solar arrays
MPPT
MPPT maximizes kev hloov dua siab tshiab ntawm lub hnub ci zog los ntawm PV panels, thiab cov nqi yuav ua tau 40 feem pua ntau npaum li PWM
MPPT tuaj yeem siv tau nyob rau hauv rooj plaub uas lub hnub ci vaj huam sib luag voltage siab dua lub roj teeb voltage.
MPPT tuaj yeem tiv taus txog 80 amps thauj khoom tam sim no
MPPT nta warranty ntev dua PWM
MPPT tsis txwv qhov nthuav dav ntawm lub hnub ci vaj huam sib luag hauv qhov system
MPPT yog tib txoj kev daws teeb meem rau lub hnub ci hluav taws xob sib xyaw
MPPT kim dua PWM. Tus nqi ntawm qee cov qauv yog ob npaug ntawm PWM tus nqi tswj
Txij li thaum MPPT muaj ntau yam khoom thiab kev ua haujlwm, nws lub cev loj dua PWM.
MPPT yog qhov nyuaj dua, yog li feem ntau lub sijhawm, peb yuav tsum ua raws li cov lus qhia thaum ntsuas lub hnub ci array
MPPT hnub ci maub los tas li yuam lub hnub ci vaj huam sib luag array wired hauv cov hlua
