Yuav ua li cas xaiv ntawm PWM hnub ci maub los thiab MPPT hnub ci maub los

Hnub ci maub los yog ib qho tseem ceeb hauv kev tsim hluav taws xob hnub ci. Solar controllers ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob hnub ci. Lub luag haujlwm tseem ceeb ntawm lub hnub ci maub los yog saib xyuas cov zis hluav taws xob thiab tam sim no ntawm lub hnub ci vaj huam sib luag thiab them lossis tawm lub roj teeb raws li xav tau.

Tsis tas li ntawd, lub hnub ci them nqi kuj tseem tuaj yeem saib xyuas thiab tiv thaiv lub roj teeb kom tsis txhob muaj xwm txheej xws li overcharge, over-discharge, thiab luv luv Circuit Court.

Lub hnub ci tswj tau muab faib ua ob hom kev tswj: PWM (Pulse Width Modulation) thiab MPPT (Maximum Power Point Tracking).

PWM solar controller yog dab tsi?

PWM hnub ci maub los yog cov cuab yeej siv los tswj kev them nyiaj ntawm lub hnub ci vaj huam sib luag thiab kev tso tawm ntawm cov roj teeb. PWM stands rau Pulse Width Modulation, uas tswj cov txheej txheem them nyiaj los ntawm kev kho cov mem tes dav ntawm qhov voltage thiab tam sim no tso tawm los ntawm lub hnub ci vaj huam sib luag. PWM hnub ci maub los xyuas kom meej tias lub hnub ci vaj huam sib luag them lub roj teeb nrog kev ua haujlwm zoo thaum tiv thaiv lub roj teeb ntawm overcharge lossis tshaj tawm. Nws feem ntau muaj ntau yam kev tiv thaiv kev ua haujlwm, xws li kev tiv thaiv overvoltage, kev tiv thaiv luv luv thiab kev tiv thaiv rov qab los tiv thaiv, txhawm rau ua kom muaj kev nyab xeeb ntawm lub cev.

Dab tsi yogMPPT hnub ci maub los?

Lub npe tag nrho ntawm MPPT hnub ci maub los yog Lub Zog Tshaj Tawm Tshaj Tawm (Maximum Power Point Tracking) hnub ci maub los. Nws yog ib tug maub los uas maximizes lub hwj chim tso zis ntawm solar panels. Lub MPPT hnub ci maub los txhim kho kev ua haujlwm ntawm lub hnub ci los ntawm kev taug qab lub zog siab tshaj plaws ntawm lub hnub ci vaj huam sib luag nyob rau lub sijhawm, uas yog qhov sib piv zoo tshaj plaws ntawm lub hnub ci vaj huam sib luag tso zis voltage thiab tam sim no.

MPPT hnub ci controllers siv algorithms thiab cov khoom siv hluav taws xob los kho qhov voltage thiab tam sim no thaum lub sij hawm them roj teeb kom ntseeg tau tias cov hnub ci vaj huam sib luag them lub roj teeb nrog kev ua haujlwm zoo. Nws tuaj yeem hloov kho lub roj teeb them hluav taws xob kom hloov mus rau cov kev hloov pauv hauv lub hnub ci vaj huam sib luag tso zis hluav taws xob, yog li txhim kho kev siv hluav taws xob.

MPPT hnub ci controllers feem ntau muaj ntau yam kev tiv thaiv kev ua haujlwm, xws li kev tiv thaiv overvoltage, kev tiv thaiv luv luv thiab kev tiv thaiv rov qab, kom ntseeg tau tias kev ua haujlwm zoo ntawm lub cev. Nws tseem tuaj yeem saib xyuas lub zog tso zis thiab them cov xwm txheej ntawm lub hnub ci vaj huam sib luag thiab muab cov ntaub ntawv cuam tshuam thiab cov ntaub ntawv txheeb xyuas los pab cov neeg siv kev tswj hwm thiab tswj lub hnub ci zoo dua.

Yog li yuav ua li cas xaiv ntawm PWM hnub ci maub los thiab MPPT hnub ci maub los?

Txawm hais tias cov neeg siv xaiv PWM hnub ci tswj lossis MPPT hnub ci tswj, lawv yuav tsum xav txog lawv tus kheej cov xwm txheej, ib puag ncig, nqi thiab lwm yam. Tsuas yog nyob rau hauv txoj kev no lawv tuaj yeem siv ntau tshaj plaws. Cov neeg siv tuaj yeem xav txog cov hauv qab no:

1. Voltage ntawm hnub ci vaj huam sib luag: PWM maub los yog tsim rau qis voltage hnub ci vaj huam sib luag, feem ntau 12V lossis 24V, thaum MPPT maub los yog tsim rau cov hluav taws xob ntau dua hnub ci vaj huam sib luag thiab tuaj yeem hloov mus rau qhov dav dav.

2. System efficiency: Piv nrog PWM hnub ci controllers, MPPT controllers muaj kev hloov dua siab tshiab efficiency thiab muaj peev xwm ua kom muaj kev siv hluav taws xob ntau ntawm cov hnub ci vaj huam sib luag. Hauv cov hnub ci loj loj, MPPT lub hnub ci tswj tau ntau dua.

3. Tus nqi: Piv nrog MPPT maub los, PWM maub los tau qis dua. Yog tias koj cov peev nyiaj tsawg thiab koj lub hnub ci me me, koj tuaj yeem xaiv PWM maub los.

4. Kev teeb tsa ib puag ncig ntawm lub hnub ci vaj huam sib luag: Yog tias lub hnub ci vaj huam sib luag tau teeb tsa hauv thaj chaw uas lub hnub ci tsis ruaj tsis khov lossis hloov pauv ntau, lossis muaj qhov sib txawv ntawm cov vaj huam sib luag, MPPT tus maub los tuaj yeem daws cov xwm txheej zoo dua. Maximize kev siv lub hnub ci zog.

Saum toj no:

Yog tias koj muaj peev nyiaj tsawg thiab tab tom nrhiav tus nqi pheej yig, yooj yim thiab txhim khu kev qha nrog lub hnub ci tsim hluav taws xob me me, ces koj tuaj yeem xaiv PWM hnub ci maub los. PWM hnub ci maub los yog kev lag luam ntau dua thiab tsim nyog rau cov tshuab hluav taws xob me me thiab nruab nrab hnub ci.

Yog tias koj muaj peev nyiaj txaus thiab lub kaw lus loj, thiab xav nrhiav kev ua haujlwm siab dua thiab ua haujlwm zoo dua, nws raug pom zoo tias koj xaiv MPPT hnub ci maub los. MPPT hnub ci controllers yog tsim rau me me, nruab nrab thiab loj hnub ci hluav taws xob tsim tshuab. Txawm hais tias nws tus nqi siab dua PWM hnub ci controllers, nws tuaj yeem txhim kho kev hloov pauv ntawm qhov system zoo dua.
