I-Inverter ye-On-Grid
R3 Inothi
I-RENAC R3 Note Series inverter ingenye yezinketho ezingcono kakhulu ezitholakala emkhakheni wezindawo zokuhlala nezohwebo ngamandla ayo obuchwepheshe, okuyenza ibe ngenye yama-inverter akhiqiza kakhulu emakethe. Ngokusebenza kahle okuphezulu okungu-98.5%, amandla athuthukisiwe okulayisha ngokweqile kanye nokulayisha ngokweqile, i-R3 Note Series imele ukuthuthuka okuvelele embonini ye-inverter.

Khipha ku-internet Okuningi Ividiyo Yomkhiqizo
Imibuzo Evame Ukubuzwa Ehlobene
- 1.I-inverter ibonisa iphutha legridi futhi ibonise umlayezo wephutha njengephutha le-voltage "Iphutha Le-Volt Yegridi" noma iphutha lefrikhwensi "Iphutha Legridi Ye-Freq" "Iphutha Legridi"?
Imbangela yesigameko:
I-voltage nemvamisa yegridi yamandla we-AC ingaphandle kwebanga elijwayelekile.
Isixazululo:
Linganisa i-voltage nemvamisa yegridi yamandla e-AC ngegiya elifanele le-multimeter, uma ingavamile ngempela, linda igridi yamandla ukuthi ibuyele kokujwayelekile. Uma i-voltage yegridi kanye nemvamisa kujwayelekile, kusho ukuthi isifunda sokutholwa kwe-inverter sinephutha. Uma ubheka, qala unqamule okokufaka kwe-DC kanye nokuphuma kwe-AC kwe-inverter, bese uvumela isiguquli sicime isikhathi esingaphezu kwemizuzu engama-30 ukuze ubone ukuthi isifunda singazimela yini ngokwaso, uma singazilulamela ngokwaso, ungaqhubeka nokusisebenzisa, uma singatholakali, ungathintana.I-Renacukuze kulungiswe noma kushintshwe. Amanye ama-circuits e-inverter, njenge-inverter main board circuit, i-circuit yokuthola, i-circuit yokuxhumana, i-inverter circuit, namanye amaphutha athambile, angasetshenziswa ukuzama le ndlela engenhla ukubona ukuthi angakwazi yini ukuzilulamela ngokwawo, bese ewashintsha kabusha noma ewashintsha uma engakwazi ukuzilulamela ngokwawo.
- 2.I-voltage ephumayo eyeqile ohlangothini lwe-AC, okubangela ukuthi isiguquli sivale noma sinciphise ngokuvikela?
Imbangela yesigameko:
Ikakhulukazi ngenxa yokuthi i-impedance yegridi inkulu kakhulu, lapho uhlangothi lomsebenzisi we-PV lokusetshenziswa kwamandla luncane kakhulu, ukudluliswa kwe-impedance kuphezulu kakhulu, okuholela ekutheni uhlangothi lwe-inverter AC lwe-voltage ephumayo luphakame kakhulu!
Isixazululo:
(1) Khulisa i-diameter yentambo yentambo yokukhiphayo, uma ikhebula lishuba, kwehlisa i-impedance. Ukuqina kwekhebula, i-impedance iyancipha.
(2) I-inverter iseduze ngangokunokwenzeka endaweni exhunywe kugridi, ikhebula lifushane, i-impedance iphansi. Isibonelo, thatha i-inverter exhunywe kugridi engu-5kw njengesibonelo, ubude bekhebula lokuphuma kwe-AC phakathi kwama-50m, ungakhetha indawo ephambanayo yekhebula elingu-2.5mm2: ubude obungu-50 – 100m, udinga ukukhetha indawo ephambanayo yekhebula engu-4mm2: ubude obungaphezu kuka-100m, udinga ukukhetha indawo ye-cross-section2.
- 3.DC side okokufaka voltage overvoltage alamu, umyalezo wephutha "PV Overvoltage" ubonisiwe?
Imbangela yesigameko:
Amamojula amaningi kakhulu axhunywe ochungechungeni, okubangela i-voltage yokufaka ohlangothini lwe-DC ukuthi idlule umkhawulo ophezulu we-voltage wokusebenza we-inverter.
Isixazululo:
Ngokusho kwezici zokushisa zamamojula we-PV, ukwehla kwezinga lokushisa elizungezile, ukuphakama kwe-voltage ephumayo. Kunconywa ukuthi ulungiselele ububanzi be-voltage yezintambo ngokuya ngemininingwane yedatha ye-inverter. Kulolu hlu lwe-voltage, ukusebenza kahle kwe-inverter kuphezulu, futhi i-inverter isengakwazi ukugcina isimo sokukhiqiza amandla okuqalisa lapho i-irradiance iphansi ekuseni nakusihlwa, futhi ngeke ibangele i-voltage ye-DC yeqe umkhawulo ongaphezulu we-voltage ye-inverter, okuzoholela ku-alamu nokuvala.
