Lokacin da za a zabar wani Grider Inverter, banda mayar da hankali ga fitowar fitarwa da na ciki na injin, akwai ikon sarrafa kayan aiki, isasshen ƙarfi, canzawa, lokaci, lokacin canzawa, da sauransu. Zabi na wadannan sigogi suna da babban tasiri ga bukatar wutar lantarki.
1) Tsarin ƙarfin lantarki:
Yana da ƙarfin lantarki na fakitin baturin. A shigarwar wutar lantarki na Offerner da fitarwa bututun mai sarrafawa iri ɗaya ne, don haka lokacin da ke zayyana da zaɓi samfurin, kula don kiyaye iri ɗaya tare da mai sarrafawa.
2) Wurin fitarwa:
Off-Grid Inverter Wuraren Wurne yana da nau'i biyu, ɗaya shine bayyananne faɗakarwar wutar lantarki, wannan ita ce alamar aiki, kamar ta ainihi fitarwa mai aiki ta hanyar ninka m , ikon ikon shine 0.8, ainihin fitarwa mai aiki shine 400W, wannan shine, ana iya tuƙi nauyin guda 400, kamar wutar lantarki, da sauransu.; Na biyun shine aikin iko, wanda naúrar shine w, irin shi na 5000W Comm-Grid Inverter, ainihin fitarwa mai aiki aiki shine 5000W.
3) Powerarfin Power:
A cikin tsarin PV Off, kayayyaki, batura, inverters, nauyin da ke tattare da kaya, kamar sahun da ke tattare da kayan aiki, kamar suttura, da sauransu, motar da ke ciki, da Farawaukar iko shine sau 3-5 Thearfin iko, don haka zauren kwastomomi yana da buƙatu na musamman don ɗaukar nauyi. Powerarfin ƙarfin shine shine ɗaukar ƙarfin injin Grider.
Inverter yana samar da farawa zuwa nauyin, wani ɓangare daga baturin ko kayan aikin PV ɗin, kuma abubuwan haɗin gwiwar kuzari ne a cikin inverter - masu ɗaukar hoto da masu shiga. Masu karfin gwiwa da masu ba da izinin adana makamashi, amma bambance-bambancen shine masu ɗaukar nauyin sujallar lantarki a cikin fam na filin lantarki, da kuma mafi girman ƙarfin gidan, da ƙari iko da zai iya adanawa. Kasancewa, a gefe guda, adana makamashi a cikin hanyar jirgin magnetic. Mafi girma da muguntar muguntar da ke haifar da hakan, mafi girman ƙirƙira, da kuma mafi ƙarfin da za a iya adanar shi.
4) Ingantawa:
Ingancin tsarin canzawa ya hada da bangarori biyu, daya shine ingancin injin da kanta, a kashe-gridid ​​mai iya juyawa, don haka karfin gwiwa ya ɗan ƙasa da mai haɗa gwiwa, gabaɗaya Tsakanin 80-90%, wanda ya fi ƙarfin ingancin injin inverter, cututtukan miji mai yawa fiye da yawan kayan maye, mafi girman tsarin Ingantaccen ƙarfin lantarki shima ya fi girma. Na biyu, ingancin cajin baturi da kuma yanke shawara yana da dangantaka, lokacin da hoton Power zai iya samar da nauyin don amfani da shi, ba tare da buƙatar shiga cikin tambarin baturin ba.
5) Lokaci na Sauya:
Tsarin tsari tare da kaya, akwai PV, baturi, masu amfani da kayan aiki, lokacin da masu amfani da wuta, a tsakanin milliseconds 10, Kwamfutocin tebur ba zai rufe ba, yana walƙiya ba zai yi fushi ba. Wadansu masu amfani da Gumi suna amfani da sauyawa ta hanyar aiki, lokacin na iya zama fiye da millise 20, kuma kwamfutar tebur na iya rufewa ko sake kunnawa.
