I-inverter iwubuchopho nenhliziyo yesistimu yokukhiqiza amandla e-photovoltaic.Enqubweni yokukhiqiza amandla e-solar photovoltaic, amandla akhiqizwe yi-photovoltaic array amandla e-DC.Kodwa-ke, imithwalo eminingi idinga amandla e-AC, futhi uhlelo lokuphakela amandla e-DC lunomkhawulo omkhulu futhi aluhambisani nokuguqula i-voltage., uhla lwesicelo sokulayisha nalo lukhawulelwe, ngaphandle kwemithwalo yamandla akhethekile, ama-inverter ayadingeka ukuze kuguqulwe amandla e-DC abe amandla e-AC.I-inverter ye-photovoltaic iyinhliziyo yesistimu yokukhiqiza amandla elanga ye-photovoltaic, eguqula okwamanje eqondile ekhiqizwa amamojula we-photovoltaic ibe yamanje eshintshanayo, futhi iyidlulisele kumthwalo wendawo noma igridi, futhi iyisisetshenziswa samandla kagesi esinemisebenzi yokuvikela ehlobene.
I-inverter yelanga ikakhulukazi yakhiwe amamojula wamandla, amabhodi wesifunda olawulayo, ama-circuit breaker, izihlungi, ama-reactors, ama-transformers, ama-contactor namakhabhinethi.Inqubo yokukhiqiza ihlanganisa izingxenye ze-elekthronikhi ezicutshungulwa ngaphambili, ukuhlanganiswa komshini okuphelele, ukuhlolwa kanye nokupakishwa komshini okuphelele.Ukuthuthuka kwayo kuncike ekuthuthukisweni kobuchwepheshe bamandla kagesi, ubuchwepheshe bedivayisi ye-semiconductor kanye nobuchwepheshe besimanje bokulawula.
Kuma-inverter elanga, ukuthuthukisa ukusebenza kahle kokuguqulwa kokunikezwa kwamandla kuyisihloko saphakade, kodwa lapho ukusebenza kahle kwesistimu kuya phezulu naphezulu, cishe kusondele ku-100%, ukuthuthukiswa okuqhubekayo kokusebenza kahle kuzohambisana nokusebenza kwezindleko eziphansi.Ngakho-ke, indlela yokugcina Ukusebenza kahle okuphezulu, kodwa futhi nokugcina ukuncintisana kwentengo enhle kuyoba isihloko esibalulekile okwamanje.
Uma kuqhathaniswa nemizamo yokuthuthukisa ukusebenza kahle kwe-inverter, indlela yokuthuthukisa ukusebenza kahle kwesistimu yonke ye-inverter kancane kancane iba enye indaba ebalulekile yezinhlelo zamandla elanga.Kuhlelo lwelanga, lapho kuvela indawo yesithunzi engu-2% -3% yendawo, kumshini wokuguqula amandla osebenzisa umsebenzi we-MPPT, amandla okukhiphayo ohlelo ngalesi sikhathi angahle ehle cishe ngamaphesenti angama-20 lapho amandla okukhiphayo engenamandla. .Ukuze uvumelane kangcono nesimo esifana nalesi, kuyindlela ephumelela kakhulu yokusebenzisa i-MPPT eyodwa-to-one noma imisebenzi eminingi yokulawula ye-MPPT kumamojula welanga elilodwa noma ingxenye.
Njengoba uhlelo lwe-inverter lusesimweni sokusebenza okuxhunywe kugridi, ukuvuza kwesistimu phansi kuzodala izinkinga ezinkulu zokuphepha;ngaphezu kwalokho, ukuze kuthuthukiswe ukusebenza kahle kwesistimu, iningi lama-solar arrays azoxhunywa ochungechungeni ukuze enze i-voltage ephezulu ye-DC yokuphuma;Ngenxa yokuvela kwezimo ezingavamile phakathi kwama-electrode, kulula ukukhiqiza i-DC arc.Ngenxa ye-voltage ephezulu ye-DC, kunzima kakhulu ukucisha i-arc, futhi kulula kakhulu ukudala umlilo.Ngokwamukelwa okubanzi kwezinhlelo ze-solar inverter, indaba yokuphepha kwesistimu izophinde ibe yingxenye ebalulekile yobuchwepheshe be-inverter.
