Lub hnub ci inverters nyob hauv tsev nyob ntev npaum li cas?

Nyob rau hauv thawj ib feem ntawm no series, pv magazine tshuaj xyuas covproductive lifespan ntawm solar panels, uas yog heev resilient. Hauv seem no, peb tshuaj xyuas cov hnub ci hluav taws xob hauv tsev nyob hauv lawv ntau hom, lawv nyob ntev npaum li cas, thiab lawv muaj zog npaum li cas.

Lub inverter, ib lub cuab yeej uas hloov lub zog DC uas tsim los ntawm lub hnub ci vaj huam sib luag rau hauv AC lub zog siv tau, tuaj yeem tuaj hauv ob peb qhov sib txawv.

Ob hom inverters tseem ceeb hauv cov ntawv thov hauv tsev yog hlua inverters thiab microinverters. Hauv qee qhov kev siv, hlua inverters tau nruab nrog module-theem fais fab hluav taws xob (MLPE) hu ua DC optimizers. Microinverters thiab DC optimizers feem ntau yog siv rau lub ru tsev nrog shading tej yam kev mob los yog sub-optimal orientation (tsis yog sab qab teb-ntsia).

Hauv cov ntawv thov uas lub ru tsev muaj qhov zoo dua azimuth (kev taw qhia rau lub hnub) thiab me ntsis tsis muaj teeb meem shading, ib txoj hlua inverter tuaj yeem yog qhov kev daws teeb meem zoo.

Txoj hlua inverters feem ntau tuaj nrog kev yooj yim txuas thiab qhov chaw nruab nrab rau kev kho yooj yim dua los ntawm cov kws tshaj lij hnub ci.Feem ntau lawv tsis tshua kim,hais Solar Reviews. Inverters feem ntau tuaj yeem raug nqi 10-20% ntawm tag nrho cov hnub ci vaj huam sib luag, yog li xaiv qhov yog qhov tseem ceeb.

Lawv kav ntev npaum li cas?

Thaum lub hnub ci vaj huam sib luag tuaj yeem kav ntev li 25 txog 30 xyoo lossis ntau dua, cov tshuab hluav taws xob feem ntau muaj lub neej luv dua, vim muaj cov khoom qub ntau dua. Ib qho ntawm qhov tsis ua hauj lwm hauv inverters yog cov electro-mechanical hnav ntawm lub capacitor hauv inverter. Cov electrolyte capacitors muaj lub neej luv dua thiab muaj hnub nyoog sai dua li cov khoom qhuav,hais tias Solar Harmonics.

EnergySage tau haisuas ib txwm nyob hauv nruab nrab txoj hlua inverter yuav kav ntev txog 10-15 xyoo, thiab yog li yuav tsum tau hloov ntawm qee qhov taw tes thaum lub neej ntawm panels.

Txoj hlua inverterfeem ntau muajcov qauv kev lees paub txij li 5-10 xyoo, ntau nrog kev xaiv txuas mus rau 20 xyoo. Qee cov ntawv cog lus hnub ci suav nrog kev saib xyuas dawb thiab saib xyuas los ntawm lub sijhawm ntawm daim ntawv cog lus, yog li nws yog qhov zoo los ntsuas qhov no thaum xaiv cov inverter.

Microinverters muaj lub neej ntev dua, EnergySage tau hais tias lawv tuaj yeem kav ntev li 25 xyoo, ze li ntawm lawv cov vaj huam sib luag. Roth Capital Partners tau hais tias nws cov kev lag luam kev sib cuag feem ntau qhia txog kev ua tsis tiav ntawm microinverter ntawm tus nqi qis dua li cov hlua inverters, txawm hais tias tus nqi pem hauv ntej feem ntau yog siab dua me ntsis hauv microinverters.

Microinverters feem ntau muaj 20 txog 25-xyoo tus qauv warranty suav nrog. Nws yuav tsum tau muab sau tseg tias thaum microinverters muaj ib tug ntev warranty, lawv tseem yog ib tug tshiab thev naus laus zis los ntawm kaum xyoo dhau los los yog li ntawd, thiab nws tseem yuav pom yog tias cov cuab yeej yuav ua tiav nws cov lus cog tseg 20+ xyoo.

Ib yam mus rau DC optimizers, uas feem ntau yog ua ke nrog lub hauv nruab nrab txoj hlua inverter. Cov khoom no yog tsim los kom kav ntev li 20-25 xyoo thiab muaj kev lav phib xaub kom phim lub sijhawm ntawd.

Raws li rau cov chaw muab kev pabcuam inverter, ob peb lub npe tuav cov lag luam tseem ceeb. Hauv Tebchaws Meskas, Enphase tus thawj coj ua lag luam rau microinverters, thaum SolarEdge coj hauv txoj hlua inverters. Tesla tau ua nthwv dej hauv qhov chaw nyob hauv txoj hlua inverter, tau txais kev sib koom ua lag luam, txawm hais tias nws tseem yuav pom tias muaj kev cuam tshuam ntau npaum li cas Tesla txoj kev nkag mus rau hauv kev lag luam yuav ua tau, hais tias tsab ntawv ceeb toom kev lag luam los ntawm Roth Capital Partners.

Ua tsis tiav

Kev tshawb fawb los ntawm kWh Analytics pom tias 80% ntawm hnub ci array tsis ua haujlwm tshwm sim ntawm qib inverter. Muaj ntau qhov laj thawj ntawm qhov no.

Raws li Fallon Solutions, ib qho ua rau yog kab sib chaws ua txhaum. Qhov siab lossis tsis tshua muaj hluav taws xob vim yog kab sib chaws txhaum cai tuaj yeem ua rau lub inverter tsis ua haujlwm, thiab cov hluav taws xob hluav taws xob lossis cov fuses tuaj yeem qhib los tiv thaiv lub inverter los ntawm qhov tsis ua haujlwm siab.

Qee lub sij hawm tsis ua hauj lwm tuaj yeem tshwm sim ntawm MLPE, qhov twg cov khoom siv hluav taws xob ua kom zoo tshaj plaws tau raug kub siab dua ntawm lub ru tsev. Yog tias kev tsim khoom raug txo qis, nws tuaj yeem ua txhaum hauv MLPE.

Installation yuav tsum tau ua kom zoo thiab. Raws li txoj cai ntawm tus ntiv tes xoo, Fallon pom zoo tias lub hnub ci vaj huam sib luag yuav tsum muaj txog li 133% ntawm lub peev xwm inverter. Yog hais tias cov panels tsis zoo sib xws rau txoj cai loj inverter, lawv yuav tsis ua haujlwm zoo.

Kev tu

Txhawm rau kom lub inverter ua haujlwm tau zoo dua rau lub sijhawm ntev, nws yogpom zootxhawm rau txhim kho cov cuab yeej hauv qhov chaw txias, qhuav nrog ntau cov cua tshiab. Cov neeg tsim khoom yuav tsum zam cov cheeb tsam uas muaj hnub ci ncaj qha, txawm hais tias cov npe tshwj xeeb ntawm sab nraum zoov inverters yog tsim los tiv thaiv tshav ntuj ntau dua li lwm tus. Thiab, nyob rau hauv multi-inverter installations, nws yog ib qho tseem ceeb kom paub tseeb tias muaj kev clearance ntawm txhua inverter, thiaj li hais tias tsis muaj cua sov hloov ntawm inverter.

Nws yog ib qho kev coj ua zoo tshaj plaws los tshuaj xyuas sab nraud ntawm lub inverter (yog tias siv tau) peb lub hlis twg, xyuas kom tsis muaj cov tsos mob ntawm lub cev puas tsuaj, thiab tag nrho cov vents thiab txias fins tsis muaj av thiab hmoov av.

Nws kuj tseem pom zoo kom teem sijhawm kuaj xyuas los ntawm cov ntawv tso cai hnub ci teeb tsa txhua tsib xyoos. Kev tshuaj xyuas feem ntau raug nqi $ 200- $ 300, tab sis qee qhov kev cog lus hnub ci muaj kev saib xyuas dawb thiab saib xyuas rau 20-25 xyoo. Thaum lub sij hawm kuaj xyuas, tus neeg soj ntsuam yuav tsum xyuas hauv lub inverter kom pom cov cim ntawm corrosion, puas, los yog kab tsuag.
