Yuav ntev npaum li cas Lub Tsev Solar Inverter kav ntev?
Lub tsev hnub ci inverter yog ib qho tseem ceeb ntawm koj lub hnub ci zog, uas hloov cov hluav taws xob DC uas tsim los ntawm koj lub hnub ci vaj huam sib luag rau AC hluav taws xob uas tuaj yeem siv los ua hluav taws xob hauv koj lub tsev thiab pub cov hluav taws xob ntau dhau mus rau hauv daim phiaj. Lub neej ntev ntawm lub hnub ci inverter yog qhov tseem ceeb rau kev txiav txim siab rau txhua tus neeg nqis peev hauv hnub ci zog. Lub neej ntev ntawm lub inverter nyob ntawm ntau yam, nrog rau nws cov khoom siv sab hauv thiab sab nraud.
Ib qho tseem ceeb uas cuam tshuam rau lub neej ntawm lub inverter yog qhov hnav thiab tsim kua muag ntawm nws cov capacitors sab hauv. Capacitors yog ib qho tseem ceeb tshaj plaws nyob rau hauv ib qho inverter thaum lawv khaws thiab tso tawm hluav taws xob los hloov DC hluav taws xob rau AC zog. Nyob rau tib lub sijhawm, cov capacitors tuaj yeem hnav tawm vim qhov kev ntxhov siab ntawm cov khoom siv ntau zaus thiab tso tawm. Qhov no tuaj yeem ua rau muaj zog tiv thaiv thiab poob ntawm kev ua haujlwm ntawm lub inverter.
Lwm qhov tseem ceeb cuam tshuam rau lub neej ntawm lub hnub ci inverter yog qhov zoo ntawm cov khoom siv sab hauv thiab lawv lub peev xwm los tiv thaiv ib puag ncig hnyav. Piv txwv li, ib qho inverter uas raug rau qhov kub thiab txias los yog high humidity tej zaum yuav muaj kev puas tsuaj ntau dua li lwm tus.
Thaum nws los txog rau qhov kev cia siab lifespan ntawm ib txwm inverter, muaj ntau yam los xav txog. Feem ntau hom inverter siv nyob rau hauv tsev solar systems yog txoj hlua inverter. Hom inverter no feem ntau muaj lub neej ntev li ntawm 10-15 xyoo. Txawm li cas los xij, nws tsim nyog sau cia tias qhov no yuav txawv nyob ntawm tus qauv tshwj xeeb thiab cov chaw tsim khoom.
Nyob rau hauv sib piv, micro inverters yog tsim los kav ntev - feem ntau nyob ib ncig ntawm 25 xyoo. Micro inverters ua haujlwm sib txawv rau cov hlua inverters nyob rau hauv uas lawv tau nruab rau ntawm txhua tus neeg lub hnub ci vaj huam sib luag, tsis yog nyob rau hauv qhov chaw nruab nrab. Qhov kev faib tawm no txhais tau hais tias micro inverters tsis tshua hnav thiab tsim kua muag vim tias txhua chav tsev yog lub luag haujlwm rau kev hloov hluav taws xob tsawg dua li lub hauv paus hlua inverter.
Installation Thiab Maintenance Ntawm Lub Tsev Solar Inverters
Txoj hlua Inverters
Ib txoj hlua inverter yog lub hauv paus inverter uas txuas tag nrho cov hnub ci vaj huam sib luag hauv lub hnub ci hluav taws xob hauv series. Cov vaj huam sib luag tsim cov DC tam sim no, uas yog sau los ntawm lub thawv sib txuas thiab xa mus los ntawm lub inverter, uas tom qab ntawd hloov lub zog khaws cia rau AC hluav taws xob. Tom qab ntawd lub zog AC muab faib rau cov khoom siv hauv tsev.
Kev teeb tsa
Txhim kho ib txoj hlua inverter yuav tsum tau ua cov kauj ruam hauv qab no:
1. Txiav txim siab qhov chaw inverter:Lub inverter yuav tsum tau muab tso rau hauv ib qho chaw yooj yim, nyiam dua nyob ze ntawm lub hnub ci vaj huam sib luag thiab ze ntawm lub ntsiab hluav taws xob vaj huam sib luag. Qhov chaw yuav tsum muaj qhov cua zoo, tawm ntawm cov menyuam yaus, thiab deb ntawm tshav ntuj ncaj qha.
2. Npaj qhov chaw:Lub chaw teeb tsa yuav tsum tsis pub muaj cov khib nyiab, theem, thiab dav txaus kom haum rau lub inverter thiab cov xaim.
3. Mount lub inverter:Lub inverter yuav tsum tau mounted ruaj ntseg rau ib phab ntsa los yog ncej, siv brackets los yog screws raws li tsim nyog.
4. Txhim kho cov kab hluav taws xob:Cov xaim yuav tsum tau xa los ntawm lub thawv sib txuas mus rau lub inverter thiab los ntawm lub inverter mus rau lub vaj huam sib luag hauv tsev. Tag nrho cov kev sib txuas yuav tsum tau nruj nreem kaw nrog cable ties thiab connectors.
5. Kuaj qhov system:Ua ntej qhib lub kaw lus, tus installer yuav tsum xyuas kom meej tias tag nrho cov kev sib txuas ntawm cov kab hluav taws xob muaj tseeb thiab qhov system ua haujlwm zoo.
Kev tu
Cov hlua inverters xav tau kev saib xyuas tsis tu ncua kom ntseeg tau tias kev ua haujlwm zoo thiab ua haujlwm ntev. Cov haujlwm saib xyuas hauv qab no yuav tsum tau ua raws sijhawm:
1. Tshawb xyuas DC input voltage tsis tu ncua thiab xyuas kom meej tias nws tsis pub dhau qhov kev txwv siab tshaj plaws ntawm lub inverter qhov specifications.
2. Tshawb xyuas lub inverter kiv cua rau cov plua plav thiab cov khib nyiab thiab ntxuav nws yog tias tsim nyog.
3. Tshawb xyuas AC cov zis hluav taws xob tsis tu ncua thiab xyuas kom meej tias nws nyob hauv qhov kev lees paub.
4. Khaws lub inverter lub qhov cua txias kom tsis txhob muaj kev cuam tshuam kom muaj qhov cua txaus.
5. Txheeb xyuas cov kev sib txuas ntawm cov hlua txuas ib ntus thiab nruj yog tias tsim nyog.
Micro-Inverters
Micro-inverters yog lwm txoj hauv kev rau cov hlua inverters uas txuas rau txhua lub hnub ci vaj huam sib luag es tsis txhob muab tso rau hauv ib qho chaw. Lawv tuaj yeem raug hu ua Distributed Inverter system.
Kev teeb tsa
Txhim kho lub micro-inverter-raws li hnub ci zog yuav tsum tau cov kauj ruam hauv qab no:
1. Txiav txim siab qhov kev tso kawm micro-inverter:Lub micro-inverters yuav tsum tau mounted ntawm txhua lub hnub ci vaj huam sib luag, zoo dua nyob rau sab nraum qab ntawm lub vaj huam sib luag.
2. Npaj qhov chaw:Lub chaw teeb tsa yuav tsum tau ua kom zoo, thiab qhov chaw teeb tsa vaj huam sib luag yuav tsum muaj lub ru tsev lub kaum sab xis kom ntseeg tau tias lub hnub ci siab tshaj plaws.
3. Mount lub hnub ci vaj huam sib luag:Lub hnub ci vaj huam sib luag yuav tsum tau mounted ruaj ntseg siv brackets tsim nyog.
4. Nruab DC cable:DC cables yuav tsum tau xa los ntawm lub vaj huam sib luag mus rau micro-inverter.
5. Txhim kho AC thaiv:Cov kab hluav taws xob AC yuav tsum tau xa los ntawm txhua lub micro-inverter mus rau lub hauv paus hlws ris lub thawv thiab ces mus rau lub ntsiab hluav taws xob vaj huam sib luag hauv tsev.
6. Kuaj qhov system:Ua ntej qhib lub kaw lus, tus installer yuav tsum xyuas kom meej tias tag nrho cov kev sib txuas ntawm cov kab hluav taws xob muaj tseeb thiab qhov system ua haujlwm zoo.
Kev tu
Micro-inverters xav tau kev saib xyuas tsawg dua li cov hlua inverters vim tias lawv tau faib thoob plaws txhua lub hnub ci vaj huam sib luag. Txawm li cas los xij, cov haujlwm hauv qab no tseem yuav tsum tau ua raws sijhawm:
1. Tshawb xyuas DC input voltage tsis tu ncua thiab xyuas kom meej tias txhua lub vaj huam sib luag qhov hluav taws xob tsis tshaj qhov siab tshaj plaws ntawm micro-inverter cov lus qhia.
2. Xyuas kom lub hnub ci vaj huam sib luag tsis muaj khib nyiab thiab puas.
Txheeb xyuas cov kev sib txuas ntawm cov hlua txuas ib ntus thiab ceev lawv yog tias tsim nyog.
Txhawm rau kom lub neej ntev ntawm koj lub hnub ci inverter, nws yog ib qho tseem ceeb kom tsis tu ncua xyuas lub sab nrauv ntawm chav tsev rau tej yam tshwm sim ntawm kev puas tsuaj, xws li tawg los yog corrosion. Kev saib xyuas tsis tu ncua tuaj yeem pab tiv thaiv kev kho tus nqi kim thiab txuas ntxiv lub neej ntawm koj lub cev.
Hauv kev xaus, lub neej ntev ntawm lub tsev hnub ci inverter nyob ntawm ntau yam, nrog rau qhov zoo ntawm cov khoom siv sab hauv thiab ib puag ncig nws raug. String inverters feem ntau kav ib ncig ntawm 10-15 xyoo, thaum micro inverters tuaj yeem kav ntev li 25 xyoo lossis ntau dua. Nws yog ib qho tseem ceeb kom tsis tu ncua xyuas thiab tswj koj lub inverter kom ntseeg tau tias nws tseem ua tau zoo rau ntau xyoo tom ntej.
