Tej zaum nws yuav tshwm sim ntau zaus uas tsis muaj lub hauv paus nkag mus rau kev cog lossis cog qoob loo rau saum roob. Nyob rau lub sijhawm no, peb tuaj yeem nruab ib lub tshuab hluav taws xob photovoltaic cia. Yog li yuav ua li cas thiaj tsim tau qhov tsim nyog photovoltaic zog cia qhov system los hloov cov kev thov hluav taws xob niaj hnub?
Qhov sib txawv ntawm qhov me me off-grid photovoltaic zog cia qhov system thiab daim phiaj-txuas kab ke yog tias qhov off-grid system tsis tas yuav tsim hluav taws xob thiab siv nws tus kheej los ntawm kab sib chaws nws tus kheej, thaum daim phiaj sib txuas yuav tsum tau ua ke nrog cov kab sib chaws. daim phiaj ua haujlwm li qub. Lub kaw lus off-grid tsis yooj yim npaum li daim phiaj sib txuas. Lub zog ntawm lub inverter thiab photovoltaic module yog zoo sib xws, tab sis ib tug off-grid system tsis yog.
Dab tsi tsis yuav tsum tau them nyiaj rau thaum tsim ib qho kev sib faib tawm?
1. Lub zog tag nrho ntawm cov khoom siv hluav taws xob tau nruab rau hauv av
2. Tag nrho lub sijhawm ua haujlwm=tus lej ntawm tag nrho watts
3. Lub teeb tej yam kev mob ntawm lub installation site thiab installation inclination
Tsuas yog los ntawm kev paub txog cov kev txwv no tuaj yeem ua cov txheej txheem zoo tshaj plaws photovoltaic off-grid system tsim tsim nyog. Lub zog cia txoj kev ntawm off-grid system yog khaws cia los ntawm lub zog cia roj teeb, thiab off-grid inverter tuaj yeem tso tawm thiab siv nws. Qhov sib piv ntawm qhov hluav taws xob tawm ntawm qhov hluav taws xob thiab qhov hluav taws xob ntawm daim phiaj sib txuas (220V / 380V) yuav tsum yog qhov sib haum xeeb rau qhov hluav taws xob ntawm daim phiaj sib txuas. Feem ntau, qhov voltage ntawm off-grid system feem ntau boost hom. Inverted los ntawm DC tsawg voltage.
Lub hwj chim ntawm lub hnub ci modules thiab inverters ntawm off-grid systems tsis tshua muaj tib yam, thiab txhua qhov chaw xav tau lub zog yuav tsum tau tsim los sib cais raws li kev siv hluav taws xob tiag tiag, uas txawv ntawm qhov sib txuas ntawm kab sib chaws. Lub kaw lus off-grid yog siv ncaj qha los ntawm DC inverter AC
