Raws li lub hnub ci zog hluav taws xob nce qib - rau tawm - cov tsev hauv tsev, RVs, nkoj, lossis lub tsev txhab nyiaj roj teeb loj- ib qho kev them nqi ib zaug feem ntau tsis tuaj yeem tuav tag nrho lub zog ntawm hnub ci arrays. Parallel charging, qhov twg ntau lub hnub ci kev tswj hwm txuas mus rau tib lub txhab nyiaj roj teeb, muab kev daws teeb meem yooj yim thiab siv tau. Txoj hauv kev no txhawb nqa lub peev xwm them nyiaj, ntxiv kev rov ua dua, thiab txhawb nqa kev loj hlob ntawm cov kab ke.
Parallel Charging ntawm Solar Charge Controllers yog dab tsi?
Thaum uas tig mus them yuav txuas cov outputs ntawm ob los yog ntau tshaj tus nqi controllers (feem ntau MPPT los yog PWM) rau ib lub txhab nyiaj roj teeb. Txhua tus maub los tswj nws tus kheej lub hnub ci array (PV sub-array), thaum lawv cov DC outputs khi ua ke ntawm lub roj teeb sab, feem ntau ntawm busbars.
Qhov kev teeb tsa no txawv ntawm qhov yooj yim paralleling hnub ci vaj huam sib luag rau hauv ib qho kev tswj hwm. Ntawm no, txhua tus tswj nws tus kheej optimizes nws cov array ntawm MPPT lossis PWM, tom qab ntawd muab lub zog sib sau ua ke rau cov roj teeb.
2. Cov Ntsiab Cai Ua Haujlwm Ua Haujlwm Sib Txuas
Ntau tus maub los txuas cov hlua photovoltaic ywj pheej raws li, qhia tib lub txhab nyiaj roj teeb, thiab paub txog kev sib koom tam sim no & synchronous them theem hloov ntawm RS485 kev sib txuas lus.
