Keeb kwm:
Raws li tam sim no lub teb chaws daim phiaj xwm kev cai, ib-theem daim phiaj-kev sib txuas fais fab chaw nres tsheb feem ntau yuav tsum tsis pub tshaj 8 kilowatts, los yog peb-theem daim phiaj-txuas tes hauj lwm yuav tsum tau. Tsis tas li ntawd, qee qhov chaw nyob deb nroog hauv Suav teb tsis muaj peb-theem fais fab, thiab lawv tuaj yeem nruab ib-theem nkaus xwb thaum lawv pom zoo rau qhov project (thaum lawv xav siv lub zog peb-theem, lawv yuav tsum them ntau txhiab yuan hauv kev tsim kho. cov nqi). Installers thiab cov neeg siv kawg yuav tsum xav txog cov nqi peev. Qhov tseem ceeb tseem yuav muab rau kev txhim kho ib-theem systems.
Hauv xyoo 2018 thiab tom ntej no, Lub Xeev yuav ua kom pom tseeb qhov kev pab cuam ntawm kev siv hluav taws xob photovoltaic nyiaj pab. Thaum ua kom ntseeg tau tus nqi peev ntawm cov chaw tsim hluav taws xob thiab cov txiaj ntsig ntawm cov neeg siv khoom, txhawm rau txhawm rau txhim kho lub peev xwm, 8KW ib-theem tshuab yuav dhau los ua qhov kev xaiv zoo tshaj plaws rau cov tuam txhab kev teeb tsa loj.
Tam sim no, lub zog siab tshaj plaws ntawm ib-theem inverters qhia los ntawm cov tuam txhab loj inverter hauv Suav teb yog 6-7KW. Thaum txhim kho 8KW fais fab nroj tsuag, txhua lub chaw tsim khoom pom zoo siv ob lub inverters ntawm 5KW + 3KW lossis 4KW + 4KW. Program. Cov phiaj xwm zoo li no yuav ua rau muaj teeb meem ntau rau tus neeg teeb tsa ntawm cov nqi tsim kho, kev saib xyuas, thiab tom qab ua haujlwm thiab tu. Qhov tshiab tshaj plaws 8KW ib-theem inverter NCA8K-DS ntawm Naton Zog, lub zog tso zis tuaj yeem ncav cuag 8KW, tuaj yeem ncaj qha daws tus neeg siv ob peb qhov mob.
Cov nram qab no Xiaobian mus rau ib tug raug 8KW fais fab nroj tsuag ua piv txwv, coj sawv daws to taub qhov no 8KW ib-theem inverter kom zoo dua. Peb caug-rau-polycrystalline 265Wp cov khoom siv ua haujlwm siab raug xaiv rau cov neeg siv khoom. Technical parameters ntawm lub Cheebtsam yog raws li nram no:
Raws li cov qauv 5KW + 3KW ib txwm muaj, yuav tsum muaj ob lub inverters, ntawm cov tshuab 3KW txuas nrog tag nrho ntawm 10 modules, 5KW cov cav tov txuas nrog ob txoj hlua, thiab txhua lub module txuas nrog 10 modules.
Ua tib zoo saib cov hluav taws xob tsis zoo ntawm Nathon Energy's 8KW ib leeg-lub koob yees duab NAC8K-DS (raws li qhia hauv qab no). 30 Cheebtsam tau muab faib ua peb txoj hlua kom nkag mus rau lub inverter:
MPPT1: 10 txoj hlua, 2 txoj hlua nkag
MPPT2: 10 txoj hlua, 1 txoj hlua nkag
Natong 8KW ib-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 qhov zoo.
1. Tus nqi zoo ntawm kev tsim kho:
Ib txheej ntawm 8KW system yog siv 5KW + 3KW lossis 4KW + 4KW hom inverter tus nqi yuav nyob ib ncig ntawm 5000 +, thaum siv Natomic NAC8K-DS ib-theem inverter, tus nqi yog nyob ib ncig ntawm 4000 +. Coupled nrog AC cable, DC cable, combiner box thiab installation nqi zog, 8KW system siv Natto zog NAC8K-DC 8KW inverter, ib txheej txheej txheem yuav txuag tau tsawg kawg yog 1,500 yuan nyob rau hauv tus nqi.
2. Kev saib xyuas thiab tom qab kev muag khoom zoo:
Siv ob lub inverters, ntau tus neeg siv tsis yog kev tshaj lij tsis paub yuav ua li cas tsim cov ntaub ntawv tsim hluav taws xob, thiab lawv tsis paub meej npaum li cas lub zog tsim tawm, thiab ob lub inverter cov ntaub ntawv kuj ua rau muaj teeb meem rau lub installer los xam lub zog tsim. Nrog rau Natco NAC8K-DS inverter, cov ntaub ntawv tsim hluav taws xob yog qhov tseeb thiab nkag siab yooj yim.
Natong Zog 8KW ib-theem ntse PV inverter kuj nruab nrog lub zog saib xyuas. Tom qab tus neeg siv sau npe, tus ntse hosting tuaj yeem pom tau. Cov neeg siv tsis tas yuav kuaj xyuas cov xwm txheej ntawm lub inverter los ntawm lawv tus kheej. Tom qab lub inverter qhia txog qhov txhaum, tus neeg siv khoom tuaj yeem tau txais kev ceeb toom tsis siv neeg ntawm lub xov tooj ntawm tes davhlau ya nyob twg. Tib lub sijhawm, Natong cov neeg ua haujlwm pabcuam tomqab muag kuj yuav tau txais thawj zaug. Rau cov ntaub ntawv tsis ua hauj lwm, pib pib hu rau tus neeg siv khoom los daws teeb meem, daws qhov teeb meem thiab tiv thaiv cov neeg siv khoom tau txais txiaj ntsig.
3. Qhov zoo ntawm lub zog tsim hluav taws xob:
1) Qhov voltage thiab zaus ntawm cov kab hluav taws xob nyob deb nroog tsis ruaj khov. Kev sib txuas ntawm ntau lub inverters tuaj yeem yooj yim ua rau resonance, voltage nce, thiab qee qhov teeb meem nyuaj dua. Kev sib txuas ntawm ntau lub tshuab nyob rau hauv lub zog network tsis muaj zog yuav ua rau cov zis tam sim no ntawm lub inverter rau oscillate, thiab lub suab nrov ntawm inductor yuav hloov; Cov yam ntxwv ntawm cov zis yuav raug deteriorated, thiab lub inverter yuav overcurrent thiab hnyav tawm ntawm lub network, uas yuav ua rau lub inverter nres thiab cuam tshuam rau cov neeg siv khoom cov nyiaj tau los. Tom qab 8KW system txais yuav Natto NAC8K-DS, cov xwm txheej no yuav raug kho kom zoo.
2).Piv rau 5KW + 3KW lossis 4KW + 4KW qauv, KW system siv tsuas yog ib qho AC cable rau NAC8K-DS inverter, uas txo qhov poob thiab nce lub zog tsim.
8KW lub zog tsim hluav taws xob kwv yees (hauv Jinan, Shandong xeev ua piv txwv):
Peb caug rau 265Wp high-efficiency Cheebtsam raug ntsia, nrog rau tag nrho ntsia muaj peev xwm ntawm 7.95 KW. System efficiency = 85%. Lub teeb cov ntaub ntawv muab los ntawm NASA tau qhia hauv cov lus hauv qab no. Qhov nruab nrab hnub ci hnub ci nyob rau hauv Jinan yog 4.28 * 365 = 1562.2 teev.
Cov tshuaj tiv thaiv txo qis los ntawm 2.5% hauv thawj xyoo thiab tom qab ntawd poob los ntawm 0.6% txhua xyoo. Ib qho 8KW system tuaj yeem suav nrog siv 8KW ib leeg-lub cev muaj zog inverter, NAC8K-DC, nrog rau kev tsim hluav taws xob sib txuas ntawm kwv yees li 240,000 kWh hauv 25 xyoo.
los xaus:
Thaum txhim kho 8KW system, kev siv 8KW ib-theem inverter piv rau cov qauv ib txwm muaj ntawm 5KW + 3KW lossis 4KW + 4KW qauv muaj txiaj ntsig zoo hauv cov nqi tsim kho thaum ntxov, kev muag khoom tom qab kev muag khoom, thiab lub zog tsim tawm. .
