1. Chii chinonzi kupisa kwekushisa?
Derating ndiko kudzorwa kuderedzwa kweiyo inverter simba.Mukushanda kwakajairwa, ma inverters anoshanda panzvimbo yavo yepamusoro yemagetsi.Panguva ino yekushanda, chiyero pakati pePV voltage nePV ikozvino inoguma mune simba guru.Iyo yakanyanya simba poindi inoshanduka inogara ichienderana neiyo solar irradiation mazinga uye PV module tembiricha.
Kudzikira kwekupisa kunodzivirira masemiconductors ari muinverter kubva pakupisa.Kana imwe nguva tembiricha inobvumirwa pazvikamu zvakatariswa zvasvika, iyo inverter inoshandura nzvimbo yayo yekushandisa kune yakaderedzwa simba.Simba rinoderedzwa mumatanho.Mune zvimwe zviitiko zvakanyanyisa, inverter ichavhara zvachose.Pakarepo tembiricha yezvikamu zvinonzwisisika inowira pasi peiyo yakakosha kukosha zvakare, iyo inverter inodzokera kune yakanyanya kunaka yekushanda nzvimbo.
Zvese zvigadzirwa zveRenac zvinoshanda nesimba rakazara uye mafungu akazara kusvika kune imwe tembiricha, pamusoro pazvo ivo vanogona kushanda neakaderedzwa ratings kudzivirira kukuvara kwechishandiso.Iyi tekinoroji inopfupikisa iyo de-rating zvimiro zveRenac inverters uye chii chinokonzera kupisa kuderera uye chii chingaitwe kudzivirira.
CHERECHEDZA
Matembiricha ese ari mugwaro anoreva tembiricha ye ambient.
2. De-rating zvimiro zveRenac inverters
Single Phase Inverters
Iyi inverter modhi dzinotevera dzinoshanda nesimba rakazara uye nemhepo izere kusvika kune tembiricha yakanyorwa mutafura iri pazasi, uye inoshanda neyakaderedzwa ratings kusvika 113 ° F / 45 ° C maererano nemagirafu ari pazasi.Iwo magirafu anotsanangura kuderedzwa kwemazuva ano maererano nekupisa.Iyo chaiyo inobuda ikozvino haingambove yakakwirira kupfuura iyo yakanyanya ikozvino yakatsanangurwa muinverter datasheet, uye inogona kunge yakaderera pane yakatsanangurwa mugirafu pazasi nekuda kweiyo inverter modhi ratings munyika uye grid.
Vatatu Phase Inverters
Aya anotevera mamodhireta anoshanda nesimba rakazara uye akazara mafungu kusvika kune tembiricha akanyorwa patafura pazasi, uye anoshanda neakaderedzwa ratings kusvika 113°F/45°C, 95℉/35℃ kana 120°F/50°C maererano. kumagirafu ari pazasi.Iwo magirafu anotsanangura kudzikiswa kwezvino (simba) zvine chekuita nekupisa.Iyo chaiyo inobuda ikozvino haingambove yakakwirira kupfuura iyo yakanyanya ikozvino yakatsanangurwa muinverter datasheet, uye inogona kunge yakaderera pane yakatsanangurwa mugirafu pazasi nekuda kweiyo inverter modhi ratings munyika uye grid.
Hybrid Inverters
Iyi inverter modhi dzinotevera dzinoshanda nesimba rakazara uye nemhepo izere kusvika kune tembiricha yakanyorwa mutafura iri pazasi, uye inoshanda neyakaderedzwa ratings kusvika 113 ° F / 45 ° C maererano nemagirafu ari pazasi.Iwo magirafu anotsanangura kuderedzwa kwemazuva ano maererano nekupisa.Iyo chaiyo inobuda ikozvino haingambove yakakwirira kupfuura iyo yakanyanya ikozvino yakatsanangurwa muinverter datasheet, uye inogona kunge yakaderera pane yakatsanangurwa mugirafu pazasi nekuda kweiyo inverter modhi ratings munyika uye grid.
3. Chikonzero chekupisa kwekushisa
Kuderera kwekushisa kunoitika nekuda kwezvikonzero zvakasiyana, kusanganisira zvinotevera:
- Iyo inverter haigone kubvisa kupisa nekuda kwemamiriro asina kunaka ekuisa.
- Iyo inverter inoshandiswa muchiedza chezuva chakananga kana kune yakakwirira ambient tembiricha inodzivirira kukwana kwakakwana kwekupisa.
- Iyo inverter yakaiswa mune kabati, wadhiropu kana imwe nzvimbo diki yakavharirwa.Nzvimbo shoma haigone kutonhorera inverter.
- Iyo PV array uye inverter haina kufananidzwa (simba rePV array richienzaniswa nesimba reiyo inverter).
- Kana iyo yekuisa saiti ye inverter iri panzvimbo isingafadzi (semuenzaniso, marefu muhuwandu hwehupamhi hwekushanda kwepamusoro kana pamusoro peMean Sea Level, ona Chikamu "Technical Data" mune inverter yekushandisa manual).Nekuda kweizvozvo, kudzikira kwetembiricha kunowanzo kuitika sezvo mhepo isinganyanyi kuderera pakakwirira uye nekudaro kusakwanisa kutonhodza zvikamu.
4. Kupisa kupisa kwema inverters
Renac inverters ine inotonhorera masisitimu akagadzirirwa kusimba ravo uye dhizaini.Inotonhorera inverters inobvisa kupisa kumhepo kuburikidza nekupisa kunyura uye fan.
Pakangoburitsa kupisa kwakawanda kupfuura iyo yakavharirwa inogona kupera, fan yemukati inobatidza (feni inobatidzwa kana tembiricha yekunyura inosvika 70 ℃) uye inokwevera mumhepo kuburikidza nematanho ekutonhodza enzvimbo yakavharirwa.Iyo fan inodzorwa nekukurumidza: inoshanduka nekukurumidza sezvo tembiricha inokwira.Chakanakira kutonhora ndechekuti inverter inogona kuramba ichidyisa musimba rayo rakakura sezvo tembiricha inokwira.Iyo inverter haina kuderedzwa kusvika iyo inotonhorera system yasvika kumiganhu yekugona kwayo.
Iwe unogona kudzivirira kuderera kwekushisa nekuisa ma inverters nenzira yekuti kupisa kunobviswa zvakakwana:
- Isa ma inverters munzvimbo dzinotonhorera(semuenzaniso dzimba dzepasi pachinzvimbo cheattics), tembiricha yepakati uye hunyoro hwehukama hunofanirwa kuzadzisa zvinotevera zvinodiwa.
- Usaisa inverter mubhabhineti, chivharo kana imwe nzvimbo duku yakavharwa, kutenderera kwemhepo kwakakwana kunofanira kupiwa kuitira kubvisa kupisa kunokonzerwa neyuniti.
- Usafumure iyo inverter kuti itungamire solar irradiation.Kana iwe ukaisa inverter kunze, isa mumumvuri kana kuisa denga pamusoro.
- Chengetedza zvibvumirano zvishoma kubva kune inverters dziri pedyo kana zvimwe zvinhu, sezvinotsanangurwa mubhuku rekuisa.Wedzera kubvumidzwa kana tembiricha yakakwira ingangoitika panzvimbo yekuisa.
- Paunenge uchiisa akati wandei inverters, chengetedza yakaringana clearance kutenderedza ma inverters kuti ive nenzvimbo yakakwana yekupisa kupisa.
5. Mhedziso
Renac inverters ine inotonhorera masisitimu akagadzirirwa kusimba rawo uye dhizaini, tembiricha inodzikira haina mhedzisiro yakaipa pane iyo inverter, asi iwe unogona kudzivirira kupisa kuderera nekuisa inverters nenzira kwayo.
