Nigute ushobora guhitamo izuba ryiburyo ryizuba rya sisitemu ya PV?

Nyuma yo guhitamo imirasire yizuba, insinga za PV, inverter hamwe nibindi bikoresho bya batiri cyangwa ibikoresho byo kubika, ntushaka kwangiriza kubwimpanuka gahunda yawe yose uhitamo agasanduku kavanze nabi.Mugihe uhisemo imirasire yizuba ikomatanya agasanduku, ubwoko, ingano nubunini bwumushinga birakomeye, kandi nibikora neza mubikorwa byo guturamo ntibishobora gukora mubikorwa byubucuruzi, nibindi.

Guhitamo imirasire yizuba iburyo bwa sisitemu ya PV ntabwo bigoye, ariko ugomba gusobanukirwa urubuga, izindi moderi za PV nubusabane bwabo nagasanduku.

Agasanduku k'imirasire y'izuba ni iki?

Imirasire y'izuba isanduku ihuza imbaraga zinjira mubiryo bimwe nyamukuru, hanyuma bigabanywa izuba riva.Mugabanye insinga, umurimo nibikoresho byaragabanutse.Imashini ikoresha imirasire y'izuba yubatswe mu buryo burenze urugero kandi burenze urugero kugira ngo irusheho kurinda no kwizerwa kwa inverter.

Intego yumurasire wizuba ni uguhuza imirongo yizuba mumasanduku imwe.Buri mugozi uhujwe na fuse ya fuse, kandi ibisohoka bya fuse terminal bihujwe mumigozi ijya mumasanduku ya inverter.Nibikorwa byibanze byimikorere yizuba, kandi birashobora kuzamurwa nibindi bintu byongeweho nka buto-gufunga byihuse nibikoresho byo gukurikirana.

Hano hari agasanduku k'izuba ka PV hagati ya inverter hamwe nizuba.Ikibanza cya PV ikomatanya izuba kigomba kuba icyambere, kuko gushyira bidakwiye bishobora kuvamo gutakaza ingufu zamashanyarazi, kandi agasanduku ka PV ntikenewe kumazu adafite imirongo itatu.Igishushanyo ni ingenzi nkutari munsi-nziza ya PV ikomatanya irashobora gutuma amafaranga ya DC BOS yiyongera kubera voltage nigihombo cyamashanyarazi.

Nigute Byoroshye Gushiraho?

Muri rusange, isanduku nziza ya DC ikomatanya akenshi biterwa nuburyo bworoshye bwo kohereza no kuyishyiraho, kimwe nikibazo ikuraho umushinga.Agasanduku hamwe na fuse yabanje kwishyiriraho hamwe ningurube irashobora kuba plug-no-gukina igisubizo kidasaba amashanyarazi yemewe gushiraho.

Kurugero, Slocable yasohoye Integrated DC Combiner Solution (ICS), igisubizo kimwe gikubiyemo ibyuma byabanjirije insinga, imiyoboro ya kabili yubutabazi, imiyoboro ikwirakwiza amashanyarazi hamwe nuburyo bubiri bwa fuse.Niba tubitse umwanya munini nigiciro gishoboka hamwe nigisubizo cyoroshye cyoroshye kandi gishoboka, abayishiraho bazayinjiza muri buri mushinga.

Nuwuhe murimo PV DC Combiner Box ikeneye?

Iyo uhisemo PV DC ikomatanya isanduku iramanuka kubiciro no kuboneka.Kubikorwa byo guturamo, hariho ibisubizo bitari bikubiyemo ibisubizo bitandukanye bishobora kugereranywa, bikabika umwanya hamwe namafaranga yinyongera ajyanye nibisubizo byabigenewe.

Nyamara, hamwe nuburyo butandukanye butandukanye, kandi bitewe nibindi bice bigize sisitemu, PV ikomatanya irashobora gukenera gukora ibirenze ibikorwa byibanze byo guhuza imirongo na fus.Ntabwo buriwukora wese afite icyerekezo cyiza-cy-izuba gikomatanya agasanduku ka buri kintu.Ukeneye guhinduka, cyangwa ubworoherane gusa?Reka tuvuge ko ufite imirasire y'izuba ibiri itandukanye rwose ikorera mumasanduku imwe ya DC hanyuma ikarasa kubitandukanya.Isanduku imwe ikomatanya irashobora gukemura ibi, mugihe izindi zishobora gusaba kwihindura.

Mubihe byashize, inverter zose zari zashizweho gusa, kandi abayishiraho barayigereranya nizuba PV array ikomatanya mbere yo kubahuza na inverter.Impinduka zidafite aho zihurira nubu zirahari, bisaba ko ushyiraho guhuza pole mbi.Iyi miterere iraruhije kandi isaba PV array ikomatanya agasanduku kugirango ifate hamwe.

Mbere yo guhitamo PV array ikomatanya, ugomba kubanza kumenya inverter - niyihe inverter yo gukoresha?Hamwe namahitamo menshi ya inverter, uhereye kumurongo gakondo uhinduranya ukageza kuri transformateur na transformateur hamwe numuyoboro wibiri MPPT, twagombaga kugabanya ibisobanuro-byujuje guhuza guhuza agasanduku kamwe kubisubizo byinshi bikubiyemo iboneza byose.

Niba bifite ishingiro, ni bishaje-bigororotse-umurongo ugereranije.Niba bidahinduka, ibibi bigomba guhuzwa kandi bigashobora guhagarika ibibi nibyiza.Noneho hariho ingano ya inverter, inverter nyinshi ubu izamuka igera kuri 1000V kandi ukeneye PV array agasanduku kugirango uhuze.

Nanone, imirasire y'izuba ikomatanya udusanduku irashobora gukora imirimo myinshi.Kurugero, MNPV8HV ya MidNite irashobora gukora ibintu bitatu icyarimwe muburyo bumwe: ibangikanye, hanyuma ikarasa kuri inverter ebyiri zitandukanye.Ubundi, agasanduku kamwe kamwe kamwe gashobora gukora imikorere idahinduka kandi igahuza ibibi bine nibyiza.

Bamwe mubakora inganda bashobora guhuza tekinoroji yo kugenzura idafite amashanyarazi mumirasire y'izuba ikomatanya, bigafasha urwego-urwego hamwe numurongo-urwego rwumuvuduko, voltage, hamwe no gukurikirana ubushyuhe.Usibye ibyiza byayo mugihe cyo kwishyiriraho, kugenzura bitanga ibitekerezo-nyabyo mugihe cyo gutangiza umurima.Muri ubu buryo, ibibazo birashobora kumenyekana mbere kandi amakosa manini arashobora gukumirwa mugihe kizaza.Hariho ikintu cyamakosa yabantu mumushinga uwo ariwo wose wubwubatsi, kandi kugenzura neza birashobora kwirinda amafaranga menshi adakenewe.

Agasanduku k'amashanyarazi gasaba kubungabunga bike, kandi urwego rwo kubungabunga rugomba kugenwa nibidukikije hamwe ninshuro zikoreshwa.Nibyiza ko ubigenzura buri gihe kugirango bisohore cyangwa bihuze, ariko agasanduku gashizwemo neza kagomba kongera ubuzima bwumushinga wawe wizuba.Ubwiza nicyo kintu cyingenzi kwitabwaho muguhitamo agasanduku gafotora ifotora, cyane cyane ko aricyo gice cya mbere cyibikoresho bihujwe no gusohora izuba.Imashini ya Photovoltaque ntabwo ihendutse ugereranije nibindi bice bigize umushinga wizuba, ariko agasanduku kavanze nabi karashobora gutuma umuntu ananirwa cyane nkumuriro numwotsi.

Nkeneye agasanduku ka PV Ikomatanya?

Ukurikije ibindi bikoresho byakoreshejwe, ahantu hamwe hashobora guhuza byose udakoresheje PV umugozi uhuza agasanduku.Ku mishinga ifite imirongo ibiri cyangwa itatu gusa (urugero: gutura bisanzwe), imirongo ikomatanya udusanduku ntabwo isabwa, kandi irakenewe gusa mumishinga minini, kuva kuri 4 kugeza 4000.Kurundi ruhande, imirongo ikomatanya irashobora kunguka mumishinga yubunini bwose.

DC umugozi uhuza udusanduku urashobora kuzana umubare muto wimigozi mukarere kamwe ko gushiraho, guhagarika no kubungabunga mubikorwa byo guturamo.DC ikomatanya agasanduku k'ubunini butandukanye ikoreshwa mubucuruzi kugirango isarure ingufu ziva mumiterere.Agasanduku ka kombineri yemerera abategura urubuga gutezimbere agasanduku k'amashanyarazi mugihe bagabanije ibiciro byibikorwa byingirakamaro.

Agasanduku k'amashanyarazi akomoka ku mirasire y'izuba kagura amafaranga atarenga magana y'amadorari kongerera agaciro cyane sisitemu y'izuba - insinga nke, gukora neza, guhagarika byihutirwa, n'umutekano muke.Ntabwo bafite ibyo byiza gusa, ahubwo biroroshye gushiraho.Niba ufite ikindi kibazo kijyanye na power combiner box, urashobora kutwandikira, Slocable izaguha igisubizo cyiza nigiciro cyiza!
