Off-grid photovoltaic fais fab kev tsim tshuab tau dav siv nyob rau hauv tej thaj chaw deb roob, thaj chaw uas tsis yog hluav taws xob, Islands tuaj, kev sib txuas lus hauv paus chaw nres tsheb thiab txoj kev teeb. Lub photovoltaic array hloov lub hnub ci zog rau hauv lub zog hluav taws xob nyob rau hauv qhov xwm txheej ntawm lub teeb, thiab muab lub zog rau lub load los ntawm lub teeb.solar charger thiab tso tawm tswj, thiab them cov roj teeb rau tib lub sijhawm; Thaum tsis muaj teeb pom kev zoo, lub roj teeb pob khoom siv hluav taws xob rau DC load los ntawm lub hnub ci them thiab cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, lub roj teeb kuj tseem xa ncaj qha mus rau lub zog ntawm lub inverter ywj pheej, uas yog hloov mus rau hauv kev hloov pauv tam sim no los ntawm kev ywj pheej inverter los muab lub zog rau qhov hloov pauv tam sim no.
Solar System Composition
(1) Hnub ciRoj teeb Modules
Lub hnub ci cell module yog qhov tseem ceeb ntawm lubhnub ci fais fab mov system, thiab nws kuj yog qhov tseem ceeb tshaj plaws nyob rau hauv lub hnub ci fais fab mov system. Nws txoj haujlwm yog los hloov lub hnub ci hluav taws xob rau hauv hluav taws xob ncaj qha tam sim no.
(2) Solar Controller
Lub hnub ci them nqi thiab tso tawm hluav taws xob kuj tseem hu ua "photovoltaic controller". Nws txoj haujlwm yog los kho thiab tswj cov hluav taws xob hluav taws xob uas tsim los ntawm lub hnub ci cell module, kom them lub roj teeb mus rau qhov siab tshaj plaws, thiab tiv thaiv lub roj teeb ntawm overcharge thiab overdischarge. nyhuv. Nyob rau hauv qhov chaw uas muaj qhov kub thiab txias sib txawv, lub photovoltaic maub los yuav tsum muaj kev ua haujlwm ntawm qhov kub thiab txias.
(3) Off-grid Inverter
Lub off-grid inverter yog lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob off-grid, uas yog lub luag haujlwm rau hloov DC lub zog rau hauv AC lub zog siv los ntawm AC loads. Txhawm rau txhim kho tag nrho cov kev ua tau zoo ntawm lub tshuab hluav taws xob photovoltaic thiab ua kom lub zog ruaj khov nyob rau lub sijhawm ntev, cov ntsuas kev ua haujlwm ntawm lub inverter yog qhov tseem ceeb heev.
(4) Roj teeb pob
Lub roj teeb feem ntau yog siv rau lub zog cia kom muab hluav taws xob hluav taws xob rau kev thauj khoom thaum hmo ntuj lossis hnub los nag. Lub roj teeb yog ib qho tseem ceeb ntawm lub kaw lus off-grid, thiab nws qhov zoo thiab qhov tsis zoo yog cuam tshuam ncaj qha rau kev ntseeg tau ntawm tag nrho cov kab ke. Txawm li cas los xij, lub roj teeb yog ib qho khoom siv nrog lub sijhawm luv tshaj plaws ntawm kev ua tsis tiav (MTBF) hauv tag nrho cov kab ke. Yog tias tus neeg siv tuaj yeem siv thiab tswj nws ib txwm, nws lub neej kev pabcuam tuaj yeem txuas ntxiv mus. Txwv tsis pub, nws lub neej kev pab cuam yuav luv luv. Cov hom roj teeb feem ntau yog cov roj ntsha lead-acid, cov roj teeb uas tsis muaj cov kua qaub thiab cov roj nickel-cadmium. Lawv cov yam ntxwv muaj nyob rau hauv cov lus hauv qab no.

Solar off-grid System Cheebtsam
Off-grid photovoltaic systems feem ntau yog tsim los ntawm photovoltaic arrays tsim los ntawm cov khoom siv hnub ci ntawm lub hnub ci, lub hnub ci them nqi thiab cov khoom siv hluav taws xob, cov roj teeb pob, off-grid inverters, DC loads thiab AC loads.
Pros:
1. Hnub ci zog yog inexhaustible thiab inexhaustible. Lub hnub ci hluav taws xob tau txais los ntawm lub ntiaj teb saum npoo tuaj yeem ua tau raws li 10,000 npaug ntawm lub ntiaj teb lub zog xav tau. Ntev npaum li lub hnub ci photovoltaic nruab rau ntawm 4% ntawm lub ntiaj teb cov suab puam, cov hluav taws xob tsim tawm tuaj yeem ua tau raws li qhov xav tau ntawm lub ntiaj teb. Hnub ci hluav taws xob tsim hluav taws xob muaj kev nyab xeeb thiab txhim khu kev qha, thiab yuav tsis raug kev txom nyem los ntawm lub zog hluav taws xob lossis kev lag luam roj tsis ruaj khov;
2. Lub hnub ci zog muaj nyob txhua qhov chaw, thiab tuaj yeem muab lub zog nyob ze, tsis muaj kev sib kis mus ntev, tsis txhob poob ntawm cov kab sib kis mus ntev;
3. Hnub ci zog tsis xav tau roj, thiab cov nqi khiav lag luam tsawg heev;
4. Tsis muaj qhov txav mus rau lub hnub ci hluav taws xob tsim hluav taws xob, nws tsis yooj yim rau kev puas tsuaj, thiab kev saib xyuas yog yooj yim, tshwj xeeb tshaj yog tsim rau kev siv tsis siv neeg;
5. Hnub ci tsim hluav taws xob yuav tsis tsim cov khoom pov tseg, tsis muaj kuab paug, suab nrov thiab lwm yam kev phom sij rau pej xeem, tsis muaj kev cuam tshuam rau ib puag ncig, yog lub zog huv zoo tagnrho;
6. Lub sij hawm tsim kho ntawm lub hnub ci hluav taws xob tsim hluav taws xob yog luv luv, yooj yim thiab hloov tau, thiab raws li qhov nce lossis txo cov load, lub hnub ci zog tuaj yeem muab ntxiv lossis txo qhov kev txiav txim siab kom tsis txhob pov tseg.
Cons:
1. Daim ntawv thov hauv av yog sib quas ntus thiab random, thiab lub zog tsim muaj feem xyuam rau cov huab cua puag. Nws tsis tuaj yeem lossis tsis tshua muaj zog thaum hmo ntuj lossis hnub huab cua thiab nag;
2. Lub zog ceev yog tsawg. Raws li cov qauv txheej txheem, lub hnub ci siv hluav taws xob tau txais hauv av yog 1000W / M^2. Thaum siv qhov loj me, nws yuav tsum nyob hauv thaj chaw loj;
3. Tus nqi tseem kim heev, thiab thawj zaug peev yog siab.
