Hauv cov hluav taws xob me me thiab nruab nrab hnub ci hluav taws xob, cov neeg siv khoom tseem ceeb tuaj ntawm cov chaw muaj hluav taws xob tsis txaus, xws li herdsmen, cov neeg nyob hauv cov kob, cov nkoj nuv ntses nruab nrab, cov cheeb tsam thaj chaw deb, nrog rau qee qhov kev sib txuas lus thiab kev saib xyuas hauv paus. chaw nres tsheb. Lub tshuab hluav taws xob me me thiab nruab nrab hnub ci daws cov kev xav tau yooj yim ntawm lub neej xws li teeb pom kev zoo, TV, kiv cua, cua txias, thiab lwm yam., lub zog siv hluav taws xob niaj hnub siv tsawg dua 50 degrees, tag nrho lub zog ntawm lub load yog tsawg dua 20kW, haum rau cov neeg siv uas muaj qee qhov kev thov rau hluav taws xob, qhov kev thov rau cov khoom siv tau zoo thiab txhim khu kev qha, tsis kim.

(1) Yog hais tias tus neeg siv muaj me ntsis inductive load, nws raug nquahu kom siv lub MPPT maub los ntxiv rau cov txheej txheem kev sib cais ntawm cov inverter siab, uas yog qhov hnyav thiab pheej yig; Yog hais tias tus neeg siv muaj ntau inductive load, nws raug pom zoo kom siv ib tug MPPT maub los ntxiv rau high-frequency cais inverter scheme, uas yog txhim khu kev qha nyob rau hauv lub hwj chim noj thiab yuav coj tej yam load.

(2) Yog tias tus neeg siv lub zog thauj khoom me me, tab sis lub sijhawm siv hluav taws xob ntev, nws raug nquahu kom xaiv cov maub los thiab inverter cais cov tswv yim, uas tuaj yeem xaiv siv cov maub los loj dua thiab cov inverter me dua los ua kom lub zog tsim thiab txo qhov system. tus nqi; Yog tias tus neeg siv lub zog thauj khoom loj, tab sis lub sijhawm siv hluav taws xob tsis ntev, nws raug nquahu kom xaiv cov maub los thiab inverter integrated scheme nrog cov kab ke yooj yim.

3. Qhov nruab nrab mus rau qhov loj-loj kev ntseeg tau tawm-daim phiaj hnub ci hluav taws xob tsim qhov system daws teeb meem

Nruab nrab thiab loj-teev off-grid hnub ci fais fab nroj tsuag, feem ntau yog siv nyob rau hauv nquag hluav taws xob, hluav taws xob hluav taws xob siab, loj peak-rau-valley tus nqi sib txawv, kev lag luam thiab kev lag luam thaj chaw uas PV tsis muaj nyob online, scenic thaj chaw, thiab lwm yam., los daws cov tib neeg lub neej niaj hnub, chaw ua haujlwm thiab kev lag luam kev lag luam ntawm kev thov hluav taws xob. Lub zog thauj khoom yog siab dua 20kW thiab qis dua 250kW, thiab kev siv hluav taws xob txhua hnub yog qis dua 500 degrees. Muaj ntau yam kev daws teeb meem rau me me thiab nruab nrab-qhov loj me off-grid systems.

Rau cov tshuab saum toj no 20kW thiab qis dua 60kW, ntau qhov ib-theem me me off-grid inverters tuaj yeem xaiv los ua ib daim phiaj sib luag. Hais txog kev hais lus, qhov kev daws teeb meem no nyuaj rau cov xaim thiab kev ua haujlwm, tab sis nws yog pheej yig dua thiab hloov tau yooj yim, thiab yog tias ib qho ntawm cov inverters tsis ua haujlwm, lub kaw lus tuaj yeem ua haujlwm txuas ntxiv. Kuj tseem muaj kev xaiv rau cov maub los thiab inverter cais cov kev daws teeb meem thiab cov maub los thiab inverter kev daws teeb meem, siv ib qho inverter ntawm nruab nrab mus rau qhov loj me, nrog cov kab hluav taws xob yooj yim thiab kev ua haujlwm yooj yim, uas tuaj yeem tsim cov khoom siv hluav taws xob sib xyaw nrog cov roj hluav taws xob hluav taws xob. , txuag ntau lub roj teeb kim heev thiab cov nqi tsim hluav taws xob tsawg tsawg piv rau cov dawb huv off-grid PV. Rau cov tshuab siab tshaj 60kW, tam sim no muaj DC Coupling "DC Coupling" thiab "AC Coupling" topologies muaj rau cov tshuab siab tshaj 60kW, uas tuaj yeem xaiv raws li qhov xwm txheej siv hluav taws xob.

4. Loj-scale ntau lub zog tawm-daim phiaj hnub ci zog tsim qhov system daws teeb meem

Qhov loj-scale ntau lub zog off-grid hnub ci fais fab nroj tsuag yog siv nyob rau hauv tej thaj chaw deb roob, Islands tuaj, mus ncig teb chaws cheeb tsam, thiab kev lag luam thiab industrial cheeb tsam uas muaj nqi hluav taws xob siab, qhov twg tsis muaj kab sib chaws, thiab lub hwj chim yog siab tshaj 250kW. Tam sim no, tib lub zog 250kW off-grid inverter tsawg dua, feem ntau yog siv ob-txoj kev lub zog cia converter, daim phiaj-txuas inverter, lossis roj teeb ua ke rau hauv micro-grid system, ntxiv rau photovoltaic thiab lub zog cia, feem ntau muaj. cua turbines, roj generators, thiab lwm yam khoom siv hluav taws xob.
