Lub ntsiab kev faib tawm ntawm lub hnub ci charger
Nov 03, 2021
Cov neeg siv hnub ci nrov ntawm kev ua lag luam feem ntau suav nrog cov tswj hnub ci zoo tib yam, PWM hnub ci tswj thiab MPPT hnub ci tswj.
Ordinary solar controller yog thawj tiam technology. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog txuas ncaj qha rau cov zis ntawm lub hnub ci vaj huam sib luag rau lub roj teeb chaw nres nkoj, thiab txiav nws thaum lub roj teeb puv. Nws yog ib qho nyuaj rau kom them tag nrho cov roj teeb vim yog lub hauv paus tsis kam ntawm lub roj teeb, thiab lub hnub ci vaj huam sib luag Nws tsis tau siv tag nrho, thiab kev them nqi hloov pauv tau tsuas yog 70 mus rau 76%, uas tau raug tshem tawm los ntawm kev ua lag luam, thiab hauv paus. tsawg tus neeg siv nws.
PWM hnub ci maub los yog thev naus laus zis thib ob, thiab feem ntau ntawm kev ua lag luam tam sim no. Txoj kev ua haujlwm yog PWM tswj. Piv nrog rau cov tswj hnub ci zoo tib yam, nws tau txhim kho ntau heev thiab tuaj yeem daws cov teeb meem ntawm cov roj teeb tsis txaus siab. Kev them nyiaj hloov pauv kev ua haujlwm yog 75-80%. , Tab sis cov hnub ci vaj huam sib luag tsis tau siv tag nrho.
MPPT hnub ci maub los yog lub cim thib peb thev naus laus zis, lub hnub ci hluav taws xob siab tshaj plaws. MPPT hnub ci maub los yog hais txog lub hnub ci maub los nrog lub luag haujlwm ntawm" Maximum PowerPoint Tracking". Nws yog ib qho khoom kho dua tshiab ntawm PWM solar controller. Lub MPPT hnub ci maub los tuaj yeem kuaj xyuas qhov voltage thiab tam sim no ntawm lub hnub ci vaj huam sib luag nyob rau lub sijhawm, thiab txuas ntxiv taug qab lub zog siab tshaj plaws (P=U * I), kom lub kaw lus ib txwm them lub roj teeb nrog lub zog siab tshaj plaws. MPPT taug qab efficiency yog 99%, thiab lub zog tsim efficiency ntawm tag nrho cov system yog siab li 97%. Nws kuj tseem muaj kev tswj hwm zoo ntawm lub roj teeb, uas tau muab faib ua MPPT them thiab qhov tsis tu ncua Voltage equalization charging thiab qhov tsis tu ncua voltage floating charging. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev txuag hluav taws xob, qhov sib txawv ntawm MPPT hnub ci tswj hloov cov tsoos PWM hnub ci controllers yog irreversible.
