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 ye-solar ikakhulukazi yakhiwa amamojula wamandla, amabhodi wesifunda okulawula, ama-circuit breakers, izihlungi, ama-reactors, ama-transformer, 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 indawo yesithunzi engu-2% -3% yasendaweni, kumshini wokushintshashintsha osebenzisa umsebenzi we-MPPT, amandla okukhiphayo esistimu ngalesi sikhathi angahle ehle ngisho nangama-20% lapho amandla okukhiphayo engekho kahle. Ukuze uvumelane kangcono nesimo esinjengalesi, kuyindlela ephumelela kakhulu yokusebenzisa i-MPPT eyodwa-to-one noma imisebenzi yokulawula ye-MPPT eminingi 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.
