MPPT (Maximum Power Point Tracking) maub los yog ib hom kev them nyiaj uas siv rau hauv lub hnub ci fais fab. Nws yog tsim los ua kom lub zog loj tshaj plaws los ntawm lub hnub ci vaj huam sib luag los ntawm kev kho qhov voltage thiab tam sim no kom phim cov yam ntxwv ntawm lub vaj huam sib luag.
Thaum lub hnub ci vaj huam sib luag raug tshav ntuj, nws tsim hluav taws xob hluav taws xob, tab sis qhov hluav taws xob thiab qib tam sim no tuaj yeem sib txawv nyob ntawm qhov siv ntawm lub hnub ci thiab lwm yam. MPPT maub los tsis tu ncua saib xyuas qhov voltage thiab tam sim no ntawm lub vaj huam sib luag thiab kho qhov voltage thiab tam sim no kom ntseeg tau tias lub vaj huam sib luag ua haujlwm ntawm nws qhov siab tshaj plaws ntawm lub zog. Qhov no tso cai rau lub hnub ci vaj huam sib luag ua haujlwm ntawm qhov ua tau zoo tshaj plaws thiab tsim lub zog tshaj plaws, uas tuaj yeem siv los them cov roj teeb lossis lub zog rau lwm yam khoom siv hluav taws xob.
MPPT controllers feem ntau yog siv nyob rau hauv off-grid thiab grid-tied hnub ci fais fab kev lag luam los tswj kev them cov roj teeb thiab lwm yam khoom siv hluav taws xob. Lawv kuj tau siv rau hauv cov twj siv hluav taws xob hnub ci, lub teeb pom kev zoo, thiab lwm yam kev siv uas ua kom lub zog tawm ntawm lub hnub ci vaj huam sib luag yog qhov tseem ceeb.
Zuag qhia tag nrho, MPPT maub los yog ib qho tseem ceeb ntawm txhua lub hnub ci hluav taws xob, vim nws ua kom ntseeg tau tias lub kaw lus ua haujlwm ntawm qhov ua tau zoo tshaj plaws thiab ua rau lub zog siab tshaj plaws ntawm cov hnub ci vaj huam sib luag.
