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 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 esinjengalesi, kuyindlela ephumelela kakhulu yokusebenzisa i-MPPT eyodwa-to-one noma imisebenzi eminingi yokulawula ye-MPPT kumamojula elanga 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.
Ngaphezu kwalokho, uhlelo lwamandla lungenisa ukuthuthukiswa okusheshayo kanye nokuthandwa kobuchwepheshe begridi ehlakaniphile. Ukuxhunywa kwegridi kwenani elikhulu lezinhlelo zamandla amasha afana namandla elanga kuletha izinselele ezintsha zobuchwepheshe ekuzinzeni kwesistimu yegridi ehlakaniphile. Ukuklama isistimu ye-inverter engakwazi ukuhambisana ngokushesha, ngokunembile nangobuhlakani namagridi ahlakaniphile kuzoba yisimo esidingekayo sezinhlelo ze-solar inverter esikhathini esizayo.
Ngokuvamile, ukuthuthukiswa kobuchwepheshe be-inverter kuthuthukiswa ngokuthuthukiswa kobuchwepheshe bamandla kagesi, ubuchwepheshe be-microelectronic kanye nethiyori yokulawula yesimanje. Ngokuhamba kwesikhathi, ubuchwepheshe be-inverter buyathuthuka bubheke emazingeni aphezulu, amandla aphezulu, ukusebenza kahle okuphezulu kanye nosayizi omncane.
