50a lithium maub los

Hauv cov tshuab hluav taws xob hnub ci, cov tswj kev them nqi (tseem hu ua hnub ci tswj hwm) yuav suav nrog cov yam ntxwv ntxiv xws li LDV, lossis tsis muaj hluav taws xob tsis sib txuas, ib lub voj voog uas txiav lub hwj chim rau lub nra thaum lub roj teeb tau tawm los txhawm rau tiv thaiv cov roj teeb kom tsis txhob puas los yog tej zaum ruined tag nrho. Lwm cov kev tswj hwm tus nqi tso tawm cov ntaub ntawv, xa cov ntaub ntawv mus rau cov chaw taws teeb qhia, thiab taug qab cov dej ntws ntawm hluav taws xob dhau sijhawm. Qee tus tswj hwm tus nqi yuav suav nrog cov yam ntxwv uas saib xyuas cov roj teeb kub kom tiv thaiv cov roj teeb los ntawm kev kub dhau.

Peb nqa tsuas yog cov khoom siv hnub ci zoo tshaj plaws los ntawm Morningstar, Outback Power, Midnite Solar, thiab ntau dua.

MPPT taug qab kev ua haujlwm tsis tsawg dua 99.5 feem pua ​​​​Kev them nqi hloov pauv kev ua haujlwm tau mus txog 98.6 feem pua.

Tag nrho cov load efficiency ntawm 96.6 feem pua ​​​​ob hom kev ua haujlwm yog xaiv tau.

MPPT lub luag haujlwm yog dab tsi?

Vim muaj kev cuam tshuam ntawm lwm yam xws li kev siv lub teeb thiab ib puag ncig, cov khoom siv hluav taws xob ntawm lub hnub ci sib txawv, thiab lub teeb siv hluav taws xob tawm ntau dua. Lub inverter nrog MPPT lub zog taug qab yog ua kom tag nrho siv lub hnub ci cell thiab ua kom nws khiav hauv lub zog taw tes. Qhov ntawd yog hais tias, nyob rau hauv cov xwm txheej ntawm lub hnub ci hluav taws xob tas li, cov zis hluav taws xob tom qab MPPT yuav siab dua qhov ua ntej MPPT, uas yog lub luag haujlwm ntawm MPPT.

Txoj Cai ntawm Power Point Tracking

Nrog rau txoj kev loj hlob ntawm cov tshuab hluav taws xob, MPPT tswj ntawm lub hnub ci cell array tam sim no feem ntau ua tiav los ntawm DC / DC hloov hluav taws xob. Nws txoj cai thaiv daim duab qhia tau pom hauv daim duab hauv qab no.

Lub photovoltaic cell array txuas nrog lub load los ntawm DC / DC Circuit Court, thiab lub zog nrhiav cov cuab yeej txuas ntxiv tshawb xyuas qhov hloov pauv tam sim no thiab qhov hluav taws xob ntawm photovoltaic array, thiab kho lub voj voog ntawm PWM tsav teeb liab ntawm DC / DC converter raws li rau qhov kev hloov.
