Yuav ua li cas xaiv lub tsev photovoltaic inverter

Raws li photovoltaics nkag mus rau ntau lub tsev, ntau thiab ntau cov neeg siv hauv tsev yuav muaj lus nug ua ntej kev teeb tsa photovoltaics: Hom inverter lawv yuav tsum xaiv li cas?

Thaum txhim kho lub tsev photovoltaics, 5 yam hauv qab no yog qhov koj yuav tsum xav txog:

01

ua kom cov nyiaj tau los

Inverter yog dab tsi? Nws yog ib qho khoom siv uas hloov DC lub zog tsim los ntawm lub hnub ci modules rau hauv AC lub zog uas tuaj yeem siv tau los ntawm cov neeg nyob hauv. Yog li ntawd, lub zog tsim hluav taws xob hloov dua siab tshiab yog qhov teeb meem tseem ceeb thaum yuav lub inverter. Tam sim no, nws tau dhau los ua tus qauv tseem ceeb rau cov tsev neeg hauv tsev los txais yuav cov khoom siv hluav taws xob siab thiab cov khoom siv tam sim no.Yog li ntawd, cov tsev neeg yuav tsum xub xav txog cov inverters hloov mus rau cov khoom siv tam sim no, uas muaj ntau dua conversion efficiency thiab txo nqi.

Tsis tas li ntawd, muaj ntau qhov ntsuas qhov ntsuas tseem ceeb rau kev sib piv:

Inverter efficiency

Qhov siab tshaj plaws efficiency thiab MPPT efficiency ntawm lub inverter yog cov cim tseem ceeb rau kev txiav txim siab lub zog tsim ntawm lub inverter. Qhov siab dua qhov ua tau zoo, lub zog tsim hluav taws xob ntau dua.

DC kev khiav hauj lwm voltage range

Qhov dav ntawm DC kev khiav hauj lwm voltage ntau, uas txhais tau hais tias pib ntxov thiab lig nres, lub sij hawm tsim hluav taws xob ntev, lub zog ntau dua.

MPPT nrhiav cov cuab yeej raug

MPPT nrhiav cov cuab yeej muaj qhov raug siab, cov lus teb ceev ceev, tuaj yeem hloov kho sai hauv kev teeb pom kev zoo, thiab txhim kho lub zog tsim hluav taws xob.

02

Hloov tau yooj yim

Ib puag ncig ntawm cov chaw siv hluav taws xob hauv tsev yog qhov nyuaj. Cov teeb meem xws li cov kab hluav taws xob nyob deb nroog thiab kev siv hluav taws xob yuav ua rau inverter AC overvoltage, undervoltage thiab lwm yam tswb. Lub inverter yuav tsum muaj cov kab sib chaws tsis muaj zog, qhov dav ntawm kab sib chaws voltage adaptability ntau, thiab overvoltage derating. , reactive fais fab nyiaj them thiab lwm yam kev ua haujlwm kom txo tau lub tswb yuam kev. Tus naj npawb ntawm MPPTs kuj yog ib qho ntawm cov cim tseem ceeb uas yuav tsum tau xav txog:multi-channel MPPT configuration tuaj yeem hloov kho tau yooj yim raws li yam xws li kev taw qhia sib txawv, lub ru tsev sib txawv, thiab cov khoom sib txawv ntawm cov khoom sib txawv.

03

yooj yim installation

Cov qauv me me thiab sib dua yog yooj yim rau nruab. Tib lub sijhawm, koj yuav tsum xaiv lub inverter uas tau teeb tsa hauv lub hoobkas ua ntej tawm hauv lub hoobkas. Tom qab nws tau teeb tsa ntawm tus neeg siv lub tsev, nws tuaj yeem siv tau tom qab lub tshuab hluav taws xob, uas txuag lub sijhawm debugging thiab yooj yim dua.

04

nyab xeeb thiab ruaj khov

Txij li muaj ntau lub tshuab hluav taws xob tau teeb tsa sab nraum zoov, IP tsis muaj dej tsis zoo thiab plua plav yog qhov ntsuas kev tiv thaiv uas tsis tuaj yeem tsis quav ntsej, uas tuaj yeem tiv thaiv lub inverter zoo los ntawm cov teeb meem tsis zoo hauv cov huab cua phem.Xaiv ib qho inverter nrog IP65 lossis siab dua rauxyuas kom lub inverter ua haujlwm ib txwm.

Nyob rau hauv cov nqe lus ntawm kev tiv thaiv kev ua haujlwm, ntxiv rau cov haujlwm tsim nyog xws li DC hloov, kev tiv thaiv kev tiv thaiv kev tiv thaiv, AC luv Circuit Court tiv thaiv, AC output overcurrent tiv thaiv, thiab rwb thaiv tsev tiv thaiv, muaj peb lwm yam tseem ceeb heev:

#

DC arc ntse nrhiav kom tau AFCI

Nws tuaj yeem txheeb xyuas cov cim arcing kom raug, kaw sai, tsis txhob muaj hluav taws kub, thiab tiv thaiv cov neeg siv kev nyab xeeb.

#

Fault kaw muaj nuj nqi

Saib thiab sau cov voltage thiab tam sim no waveforms ntawm AC sab ntawm lub inverter nyob rau hauv lub sij hawm tiag tiag kom sai nrhiav teeb meem.

#

Ntse IV Scanning thiab Diagnosis

Nws tuaj yeem txheeb xyuas txoj hlua tsis raug thiab nrhiav pom cov teeb meem. Nrog ntau yam kev lav phib xaub, lub chaw nres tsheb fais fab tuaj yeem ua haujlwm ruaj khov, ua rau cov neeg siv kev thaj yeeb nyab xeeb.

05

Kev Tswj Xyuas Ntse

Nyob rau niaj hnub digital era, cov cuab yeej ntse tuaj yeem muab cov neeg siv yooj yim dua. Inverter homnruab nrog ntse tswj platformstuaj yeem nqa tau yooj yim rau cov neeg siv hauv kev tswj hwm chaw nres tsheb fais fab: Ua ntej, koj tuaj yeem siv koj lub smartphone los saib xyuas lub chaw nres tsheb fais fab, xyuas cov ntaub ntawv chaw nres tsheb fais fab txhua lub sijhawm thiab nyob qhov twg, thiab nkag siab txog cov xwm txheej ntawm lub chaw nres tsheb fais fab raws sijhawm. Nyob rau tib lub sijhawm, cov tuam txhab lag luam tuaj yeem tshawb pom cov teeb meem los ntawm kev kuaj xyuas cov chaw taws teeb, txheeb xyuas qhov ua tsis tiav, muab kev daws teeb meem, thiab daws cov teeb meem nyob deb ntawm lub sijhawm.
