1. Yintoni ukunciphisa ubushushu?

Ukunciphisa kukunciphisa okulawulwayo kwamandla e-inverter.Kumsebenzi oqhelekileyo, ii-inverters zisebenza kwindawo yazo yamandla aphezulu.Kule ndawo yokusebenza, umlinganiselo phakathi kwe-PV voltage kunye ne-PV yangoku iphumela kumandla aphezulu.Amandla aphezulu atshintsha rhoqo ngokuxhomekeke kumanqanaba okukhanya kwelanga kunye nobushushu bemodyuli ye-PV.

Ukwehla kobushushu kuthintela i-semiconductors ebuthathaka kwi-inverter ekutshiseni ngokugqithisileyo.Emva kokuba iqondo lokushisa elivumelekileyo kumacandelo abekwe esweni lifikelelwe, i-inverter iguqula indawo yayo yokusebenza kwinqanaba elincitshisiweyo lamandla.Amandla ancitshiswa ngamanyathelo.Kwezinye iimeko ezinzima, i-inverter iya kuvala ngokupheleleyo.Ngokukhawuleza ukuba ubushushu bamacandelo abuthathaka buwela ngaphantsi kwexabiso elibalulekileyo kwakhona, i-inverter iya kubuyela kwindawo efanelekileyo yokusebenza.

Zonke iimveliso zeRenac zisebenza ngamandla apheleleyo kunye nemisinga egcweleyo ukuya kuthi ga kwiqondo lobushushu elithile, apho zinokusebenza ngokulinganisa okucuthiweyo ukuthintela ukonakala kwesixhobo.Eli nqaku lobugcisa lishwankathela iipropathi zokunciphisa umlinganiselo wee-inverters zeRenac kunye nokuba yintoni ebangela ukuhla kweqondo lobushushu kwaye yintoni enokwenziwa ukunqanda oko.

Onke amaqondo obushushu kuxwebhu abhekisa kwiqondo lobushushu le-ambient.

2. Iipropati zokunciphisa umlinganiselo wee-inverters zeRenac

Iziguquli zeSigaba esinye

Iimodeli ezilandelayo ze-inverter zisebenza ngamandla apheleleyo kunye nemisinga egcweleyo ukuya kumaqondo okushisa adweliswe kwitheyibhile engezantsi, kwaye isebenze ngokulinganisa okuncitshisiweyo ukuya kwi-113 ° F / 45 ° C ngokwegrafu engezantsi.Iigrafu zichaza ukuncitshiswa kwangoku ngokumalunga nobushushu.Imveliso yangoku ayisoze ibephezulu kunobona bukhulu bangoku buchazwe kwiinverter datadata, kwaye inokuba ngaphantsi kunokuba ichazwe kwigrafu engezantsi ngenxa yokulinganisa imodeli ethile yoguqulo lwelizwe kwilizwe nakwigridi.

Iziguquli zeSigaba esiThathu

Le mifuziselo ilandelayo ye-inverter isebenza ngamandla apheleleyo kunye nemisinga egcweleyo ukuya kumaqondo obushushu adweliswe kwitheyibhile engezantsi, kwaye isebenza ngemilinganiselo encitshisiweyo ukuya kuthi ga kwi-113°F/45°C, 95℉/35℃ okanye 120°F/50°C ngokwe kwiigrafu ezingezantsi.Iigrafu zichaza ukucuthwa kwangoku (amandla) ngokumalunga nobushushu.Imveliso yangoku ayisoze ibephezulu kunobona bukhulu bangoku buchazwe kwiinverter datadata, kwaye inokuba ngaphantsi kunokuba ichazwe kwigrafu engezantsi ngenxa yokulinganisa imodeli ethile yoguqulo lwelizwe kwilizwe nakwigridi.

3. Isizathu sokuhla kobushushu

Ukuhla kobushushu kwenzeka ngenxa yezizathu ezahlukeneyo, kubandakanywa nezi zilandelayo:

• I-inverter ayikwazi ukutshabalalisa ukushisa ngenxa yeemeko ezingathandekiyo zokufakela.
• I-inverter isetyenziswa kwilanga elithe ngqo okanye kumaqondo obushushu aphezulu athintela ukutshatyalaliswa kobushushu okwaneleyo.
• I-inverter ifakwe kwikhabhinethi, i-closet okanye enye indawo encinci evaliweyo.Indawo encinci ayincedi ukupholisa inverter.
• Uluhlu lwe-PV kunye ne-inverter azihambelani (amandla oluhlu lwe-PV xa kuthelekiswa namandla e-inverter).
• Ukuba indawo yokufakela i-inverter ikwindawo yokuphakama engathandekiyo (umzekelo, ukuphakama kuluhlu lobude bobude bokusebenza okanye ngaphezulu kweNqanaba loLwandle oluMean, jonga iCandelo “Idatha yobuGcisa” kwi-inverter yokusebenza manual).Ngenxa yoko, ukuhla kweqondo lobushushu kusenokwenzeka ukuba kwenzeke njengoko umoya ungaxinana kakhulu kwindawo ephakamileyo kwaye ngenxa yoko ungakwazi ukupholisa amalungu.

4. Ukutshatyalaliswa kobushushu kwee-inverters

Abaguquli beRenac baneenkqubo zokupholisa ezilungiselelwe amandla abo kunye noyilo.Iziguquli ezipholileyo zibuchitha ubushushu emoyeni ngeesinki zobushushu kunye nefeni.

Nje ukuba isixhobo sivelise ubushushu obuninzi kunokuba indawo ebiyelweyo inokuphelisa, i-fan yangaphakathi iyacima (ifeni iyacima xa ubushushu be-heat sink ifikelela kuma-70℃) kwaye itsale umoya ngemibhobho yokupholisa yendawo ebiyelweyo.I-fan ilawulwa ngesantya: ijika ngokukhawuleza njengoko ubushushu bukhuphuka.Inzuzo yokupholisa kukuba i-inverter inokuqhubeka isondla kumandla ayo aphezulu njengoko ubushushu buphakama.I-inverter ayichithwanga de inkqubo yokupholisa ifikelele kwimida yomthamo wayo.

Unokunqanda ukuhla kobushushu ngokufaka ii-inverters ngendlela yokuba ubushushu buchithwe ngokwaneleyo:

• Faka ii-inverters kwiindawo ezipholileyo(umz. amagumbi angaphantsi endaweni yee-attics), iqondo lobushushu le-ambient kunye nokufuma okunxulumeneyo kufuneka kuhlangabezane nezi mfuno zilandelayo.

• Musa ukufaka i-inverter kwikhabhinethi, i-closet okanye enye indawo encinci evaliweyo, ukujikeleza komoya okwaneleyo kufuneka kunikezelwe ukwenzela ukutshabalalisa ukushisa okwenziwa yiyunithi.
• Musa ukuveza i-inverter ngqo kwi-radiation yelanga.Ukuba ufaka i-inverter ngaphandle, yibeke emthunzini okanye ufake uphahla phezulu.

• Gcina ubuncinci bokucoceka kwii-inverters ezikufutshane okanye ezinye izinto, njengoko kuchaziwe kwincwadana yokufakela.Ukwandisa iindawo ezicacileyo ukuba amaqondo obushushu aphezulu anokwenzeka kwindawo yofakelo.

• Xa ufaka ii-inverters ezininzi, gcina imvume eyaneleyo malunga nee-inverters ukuqinisekisa indawo eyaneleyo yokutshatyalaliswa kobushushu.

5. Isiphelo

Abaguquli beRenac baneenkqubo zokupholisa ezilungiselelwe amandla abo kunye noyilo, ukwehla kobushushu akunaziphumo zibi kwi-inverter, kodwa unokunqanda ukwehla kobushushu ngokufaka ii-inverters ngendlela echanekileyo.
