mppt 20a hnub ci nqi tswj

Nyiv yog thawj lub tebchaws los txhawb lub hnub ci zog. Xyoo 1994, Nyiv tau siv qhov nyiaj pab thiab kev txhawb zog los txhawb 3, 000 watts ntawm "main-connected solar photovoltaic system" rau ib tsev neeg.

Hauv thawj xyoo, # 20a lub roj teeb charger controller mppt tsoomfwv tau pab nyiaj 49 feem pua ​​​​ntawm cov nyiaj, thiab cov nyiaj pab tom qab tau poob qis ib xyoos ib zaug.

Lub "mains-connected parallel solar photovoltaic system" siv lub hnub ci hlwb los muab lub zog rau nws tus kheej thaum muaj hnub ci txaus. #regulateur hnub ci mppt Yog tias muaj lub zog ntau dhau, nws muab cais tawm.

Thaum lub zog tsim hluav taws xob tsis txaus lossis tsis txaus, lub zog yuav tsum tau muab los ntawm lub tuam txhab fais fab.

Los ntawm xyoo 1996, muaj 2,600 lub hnub ci hluav taws xob hauv Nyij Pooj, #mppt tus nqi tswj cov khoom siv hluav taws xob nrog tag nrho lub peev xwm ntawm 8 lab watts. Ib xyoos tom qab, muaj 9,400 kev teeb tsa thiab tag nrho cov peev txheej tau mus txog 32 lab watts.

Nrog rau kev paub txog kev tiv thaiv ib puag ncig thiab cov txheej txheem ntawm tsoomfwv cov nyiaj pab,

nws tau kwv yees tias qhov kev thov rau lub hnub ci vaj tsev nyob hauv Nyij Pooj kuj tseem yuav nce sai.
