Kev paub txog cov muaj pes tsawg leeg thiab cov hauv paus ntsiab lus ntawm cov tshuab hluav taws xob photovoltaic

Lub tshuab hluav taws xob photovoltaic feem ntau suav nrog kab sib txuas thiab tawm kab sib chaws. Daim phiaj txuas txuas xa cov hluav taws xob tsim los ntawm cov tshuab photovoltaic nyob rau tib lub sijhawm rau lub teb chaws daim phiaj. Cov kab sib txuas txuas feem ntau muaj xws li photovoltaic modules, inverters, tis thawv, thiab lwm yam khoom siv. Lub off grid system ua haujlwm ntawm nws tus kheej thiab tsis cia siab rau pej xeem lub zog hluav taws xob. Cov kab hluav taws xob tawm yuav tsum tau nruab nrog cov roj teeb thiab lub hnub ci tswj nrog lub zog cia ua haujlwm kom ruaj khov lub zog, thiab tuaj yeem muab lub zog rau lub nra thaum lub tshuab hluav taws xob photovoltaic tsis tsim hluav taws xob lossis txuas ntxiv tsim hluav taws xob tsis txaus rau hnub huab cua.

1. Photovoltaic modules

Photovoltaic modules yog qhov tseem ceeb ntawm tag nrho cov tsim hluav taws xob tsim hluav taws xob, tsim los ntawm photovoltaic modules lossis kev sib txuas ntawm photovoltaic modules ntawm txawv specifications txiav los ntawm laser txiav tshuab los yog steel hlau txiav machine. Vim yog qhov me me tam sim no thiab qhov hluav taws xob ntawm ib lub xov tooj ntawm tes photovoltaic, nws yog ib qho tsim nyog yuav tsum tau ua ntej txuas nws nyob rau hauv series kom tau txais high voltage, ces txuas nws nyob rau hauv parallel kom tau txais high tam sim no, tso tawm los ntawm ib tug diode, thiab ces ntim rau hauv ib tug stainless. steel, aluminium lossis lwm yam tsis yog xim hlau. Txhim kho lub iav rau saum thiab sab nraub qaum, them cov roj nitrogen, thiab kaw nws. Los ntawm kev sib txuas cov photovoltaic modules nyob rau hauv series lossis parallel, photovoltaic module array, tseem hu ua photovoltaic array, yog tsim.

2. Tus tswj

Lub photovoltaic maub los yog ib qho khoom siv tswj tsis siv neeg uas tuaj yeem tiv thaiv overcharging thiab tawm ntawm cov roj teeb. Nws siv lub siab ceev CPU microprocessor thiab lub siab-precision A / D analog-rau-digital converter. Nws yog microcomputer cov ntaub ntawv tau txais thiab kev saib xyuas kev tswj hwm, uas tuaj yeem ceev thiab lub sijhawm ua haujlwm tam sim no ntawm lub tshuab hluav taws xob photovoltaic, tau txais cov ntaub ntawv ua haujlwm ntawm PV chaw nres tsheb txhua lub sijhawm, thiab khaws cov ntaub ntawv keeb kwm yav dhau los ntawm PV chaw nres tsheb, Qhov no muab lub hauv paus raug thiab txaus rau kev ntsuam xyuas qhov tsim nyog ntawm PV system tsim thiab txheeb xyuas qhov kev ntseeg tau ntawm qhov system tivthaiv zoo. Nws kuj muaj kev sib txuas lus cov ntaub ntawv sib txuas lus muaj nuj nqi, uas tuaj yeem tswj hwm hauv nruab nrab thiab tswj hwm ntau lub photovoltaic system subsystems.

3. Inverter

Lub inverter yog ib qho khoom siv uas hloov cov tam sim no ncaj qha tsim los ntawm photovoltaic fais fab tuag mus rau qhov hloov tam sim no. Photovoltaic inverters yog ib qho tseem ceeb ntawm kev sib npaug hauv photovoltaic array systems thiab tuaj yeem siv ua ke nrog cov khoom siv hluav taws xob AC. Hnub ci inverters muaj kev ua haujlwm tshwj xeeb ua ke nrog photovoltaic arrays, xws li qhov siab tshaj plaws lub zog taw tes nrhiav thiab tiv thaiv Islanding.

4. Roj teeb

Cov roj teeb yog cov cuab yeej siv los khaws cov hluav taws xob hauv cov tshuab hluav taws xob photovoltaic. Tam sim no, muaj plaub hom roj teeb uas siv: cov roj teeb uas tsis muaj cov kua qaub-ua kua qaub, cov roj teeb txhuas-acid zoo tib yam, cov roj teeb colloidal, thiab cov roj teeb alkaline nickel cadmium. Cov khoom siv dav siv xws li txhuas-acid txij nkawm tsis muaj roj teeb thiab cov roj teeb colloidal.

5. Lub hauv paus ntsiab lus ua haujlwm: Thaum nruab hnub, lub hnub ci ci rau ntawm photovoltaic modules, tsim hluav taws xob DC, hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob, thiab tom qab ntawd xa mus rau cov maub los. Tom qab overcharging tiv thaiv los ntawm tus maub los, lub zog hluav taws xob kis tau los ntawm photovoltaic modules raug xa mus rau lub roj teeb cia thaum xav tau.
