Tom qab:
Raws li cov phiaj xwm thoob plaws lub teb chaws tam sim no, ib leeg-theem sib txuas-cov kilowatts, lossis peb-theem sib txuas ua ke. Tsis tas li ntawd, qee qhov chaw nyob deb nroog hauv Suav teb tsis muaj peb-theem zog, thiab lawv yuav tsum tau nruab peb-theem lub zog, lawv yuav tsum them kaum ob txhiab tus nqi tsim kho). Nruab thiab cov neeg siv kawg yuav tsum xav txog cov nqi peev. Qhov tseem ceeb yuav muab rau txhim kho cov nruab nrab-theem.
Nyob rau hauv 2018 thiab rov qab, lub xeev yuav ua kom pom tseeb kev txhawb nqa cov ntaub ntawv ntawm photovoltaic tiam. Thaum ua kom ntseeg tau qhov peev txheej ntawm cov hluav taws xob cov nroj tsuag thiab cov txiaj ntsig ntawm cov neeg siv khoom, nyob rau hauv ib leeg-theem-txheej txheem yuav dhau los ua qhov kev xaiv zoo tshaj plaws rau cov tuam txhab loj rau cov teeb tsa loj
Tam sim no, lub zog siab tshaj plaws ntawm ib-theem inverters qhia los ntawm cov tuam txhab inverter loj hauv Suav teb yog 6-7kW. Thaum txhim kho 8kw hluav taws xob nroj tsuag, txhua qhov chaw tsim khoom pom zoo siv ob lub inverters ntawm 5kW + 3kW lossis 4kW + 4kW. Kev pab cuam. Xws li txoj kev npaj yuav nqa teeb meem rau cov teeb meem ntawm cov nqi tsim qauv, kev tshuaj xyuas, thiab tom qab ua haujlwm. Tshiab 8Kw ib leeg-theem inverter nca8k-ds ntawm naton zog, lub zog tso zis tuaj yeem ncav cuag 8kW, tuaj yeem daws ncaj qha rau cov neeg siv cov ntsiab lus mob ntau dua.
Cov Xiaobian hauv qab no mus rau qhov raug cog qoob loo 8kw lub zog ua piv txwv, coj txhua tus kom nkag siab txog qhov no 8kW ib leeg-theem inverter kom zoo dua. Peb caug-rau polycrystalline 265WP cov khoom siv ua haujlwm siab tau raug xaiv rau cov neeg siv khoom. Cov lus tsis zoo ntawm cov cheebtsam yog raws li hauv qab no:
Raws li cov tsoos 5KW + 3kW qauv, ob lub inverters yog qhov yuav tsum tau, ntawm lub tshuab 3kW no txuas nrog ob txoj hlua, thiab txhua qhov module txuas nrog 10 modules.
Saib ntawm cov hluav taws xob tsis sib xws ntawm Naton Zog lub 8kW ib-lub koob yees duab Nac8k-DS (raws li qhia hauv qab no). 30 feem ntau muab faib ua peb txoj hlua los nkag mus rau hauv Inverter:
MPPT1: 10 txoj hlua, 2 txoj hlua nkag
MPT2: 10 Strings, 1 Txoj Hlua
Natong 8KW Ib Leeg-Theem Inverter Nac8k-DS Thawj Daim Duab Hluav Taws Xob:
Los ntawm kev sib piv, nws tau pom tias siv NATO Zog NAC8K-DS inverter muaj cov txiaj ntsig zoo.
1. Tus nqi kom zoo dua ntawm kev tsim kho:
Ib txheej ntawm 8kW system yog tias siv 5kW + 3kW + 4KW Hom Kev Siv Hauv Natomic Nac8k-Ds Ib-theem Inverter, tus nqi yog ib ncig 4000 +. Coupled nrog AC Cable, DC Cable, Combiner Box thiab DC 8kW Inverter, ib pawg ntawm cov tshuab tuaj yeem txuag tsawg kawg 1,500 yuan hauv tus nqi.
2. Saib xyuas thiab tom qab-kev muag khoom zoo:
Siv ob lub inverers, ntau cov neeg tsis muaj kev tshaj lij tsis paub yuav ua li cas cov ntaub ntawv muaj zog, thiab lawv tsis paub meej tias yuav tsim teeb meem rau kev teeb tsa los laij lub hwj chim ntau tiam. Nrog NATco Nac8k-DS Inverter, lub zog txhawb cov ntaub ntawv yog qhov tseeb thiab nkag siab yooj yim.
Natong Zog 8KW Ib Leeg-Theem Ntse Pv Inverter kuj tseem tau nruab nrog lub zog saib xyuas. Tom qab cov neeg sau npe xaiv tsa, tus ntse hosting tuaj yeem pom tau. Cov neeg siv tsis tas yuav tshawb xyuas qhov xwm txheej ntawm lub inverter los ntawm lawv tus kheej. Tom qab Inverter cov ntawv tshaj tawm cov txhaum, cov qhua tuaj noj mov tuaj yeem tau txais kev ua kom tsis siv neeg ntawm lub xov tooj ntawm tes. Nyob rau tib lub sijhawm, Natong's tom qab muag cov neeg ua haujlwm pabcuam yuav tau txais thawj zaug. Rau cov ntaub ntawv tsis ua tiav, ua raws li cov neeg yuav khoom kom daws tau cov qhua tuaj noj mov, daws cov teeb meem thiab tiv thaiv tus neeg yuav khoom muaj txiaj ntsig.
3. Qhov zoo ntawm lub hwj chim tiam:
1) .Qhov voltage thiab zaus ntawm cov kab ke nyob deb nroog tsis ruaj khov. Parallel kev sib txuas ntawm ntau inverters tau yooj yim ua rau resonance, voltage nce, thiab qee qhov kev hloov pauv ntau yam. Parallel resonance ntawm ntau cov cav tov raws li cov kev siv hluav taws xob tsis muaj zog yuav ua rau cov zis tam sim no, thiab lub suab tsis ncaj ncees ntawm lub inductor yuav hloov; Cov yam ntxwv rau cov zis yuav raug hluav taws xob tsis txaus ntseeg, thiab cov inverter yuav overcurrent thiab ua kom cov inverter nres thiab cuam tshuam rau cov qhua tuaj noj mov. Tom qab 8kW system adops ib natto nac8k-ds, cov mob no yuav ua tau zoo dua.
2) .Cov rau 5KW + 3KW + 3KW lossis 4KW + 4KW qauv, KW system siv tsuas yog ib pob cable
8KW system hluav taws xob txhawb kev kwv yees (hauv Jinan, Shandong xeev ua piv txwv):
Peb caug-rau 265WP cov thaj tsam siab tau zoo tau nruab tau, nrog tag nrho cov peev txheej tag nrho ntawm 7.95 kW. Kev ua haujlwm zoo = 85%. Cov ntaub ntawv teeb tau muab los ntawm NASA yog qhia nyob rau hauv cov lus hauv qab no. Qhov nruab nrab txhua hnub hnub ci nyob rau hauv Jinan yog 4.28 * 365 = 1562,2 teev.
Cov khoom tivthaiv helenuenates los ntawm 2.5% nyob rau hauv thawj xyoo thiab tom qab ntawd tsis lees paub txog 0.6% txhua xyoo. Lub kaw lus 8kW tuaj yeem suav tau siv 8kW ib leeg-lub cev muaj zog inverter, NAC8K-DC, nrog kev sib tw ua haujlwm ntawm kwv yees li 240,000 kw hauv 25 xyoos.
kom suav tau:
Thaum txhim kho ib qho system 8kW, kev siv ntawm 8kW ib-theem inverter piv rau cov qauv siv tau zoo ntawm kev tsim kho kom raug nqi, tom qab muag khoom, thiab muaj hwj chim rau cov khoom muag
