I-Inverter ye-On-Grid
R3 Nawo
I-RENAC R3 Navo Series inverter yakhelwe ngokukhethekile amaphrojekthi amancane ezimboni nezohwebo. Ngomklamo wamahhala we-fuse, umsebenzi we-AFCI ongawukhetha kanye nokunye ukuvikela okuningi, iqinisekisa izinga eliphezulu lokuphepha lokusebenza. Nge-max. ukusebenza kahle kuka-98.8%, amandla kagesi aphezulu e-DC angu-1100V, ububanzi be-MPPT ebanzi kanye nomthamo ophansi wokuqalisa ongu-200V, kuqinisekisa ukukhiqizwa kwamandla kwangaphambili kanye nesikhathi eside sokusebenza. Ngesistimu yokungenisa umoya ethuthukisiwe, i-inverter ichithwa ukushisa kahle.

Khipha ku-internet Okuningi Ividiyo Yomkhiqizo
Imibuzo Evame Ukubuzwa Ehlobene
- 1.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.
- 2.Ukusebenza kwe-insulation yesistimu ye-PV yehlisiwe, ukumelana nokufakwa kwe-insulation emhlabathini kungaphansi kuka-2MQ, futhi imilayezo yephutha "Iphutha lokuhlukaniswa" kanye "Iphutha Lokuzihlukanisa" iyaboniswa.
Imbangela yesigameko:
Ngokuvamile amamojula e-PV, amabhokisi okuhlanganayo, izintambo ze-DC, iziguquli, amakhebula e-AC, amatheminali, nezinye izingxenye zolayini ukuze kucekelwe phansi umonakalo oyisiyingi esifushane noma ungqimba wokufakelwa, izixhumi zezintambo ezixekethile emanzini, njalonjalo.
Isixazululo:
Nqamula igridi, kanye ne-inverter, hlola ukumelana nokufakwa kwengxenye ngayinye yekhebula phansi, thola inkinga, bese ubuyisela ikhebula elihambisanayo noma isixhumi!
- 3.I-voltage ephumayo eyeqile ohlangothini lwe-AC, ebangela ukuthi isiguquli sivale noma siphazamiseke ngokuvikela?
Imbangela yesigameko:
Kunezici eziningi ezithinta amandla okukhipha izitshalo zamandla e-PV, okuhlanganisa inani lemisebe yelanga, i-angle enyakazayo yemodyuli yeseli yelanga, ukuvinjelwa kothuli nesithunzi, kanye nezici zokushisa zemodyuli.
Amandla esistimu aphansi ngenxa yokucushwa kwesistimu okungalungile nokufakwa.
Simibono :
(1) Hlola ukuthi amandla emojula ngayinye ye-PV anele yini ngaphambi kokufakwa.
(2) Indawo yokufaka ayinawo umoya ohlanzekile, futhi ukushisa kwe-inverter akusakazwa ngesikhathi, noma kuvezwa ukukhanya kwelanga ngokuqondile, okubangela ukuthi izinga lokushisa le-inverter libe phezulu kakhulu.
(3) Lungisa i-engeli yokufaka nokuma kwemojula ye-PV.
(4) Hlola imojuli ukuze uthole izithunzi nothuli.
(5) Ngaphambi kokufaka izintambo eziningi, hlola i-voltage yesiyingi evulekile yentambo ngayinye enomehluko ongekho ngaphezu kuka-5V. Uma i-voltage itholakala ingalungile, hlola izintambo nezixhumi.
(6) Uma uyifaka, ingafinyelelwa ngamaqoqo. Lapho ufinyelela iqembu ngalinye, rekhoda amandla eqembu ngalinye, futhi umehluko wamandla phakathi kwezintambo akufanele ube ngaphezu kuka-2%.
(7) I-inverter inokufinyelela okubili kwe-MPPT, indlela ngayinye amandla okufaka angamaphesenti angama-50 kuphela wamandla aphelele. Empeleni, indlela ngayinye kufanele yakhelwe futhi ifakwe ngamandla alinganayo, uma kuphela ixhunywe endleleni eyodwa yokugcina i-MPPT, amandla okukhipha azokwehliswa ngesigamu.
(8) Ukuthinta kabi isixhumi sekhebula, ikhebula lide kakhulu, ububanzi bocingo mncane kakhulu, kukhona ukulahleka kwamandla kagesi, futhi ekugcineni kubangele ukulahleka kwamandla.
(9) Thola ukuthi ingabe i-voltage ingaphakathi kwebanga likagesi ngemva kokuba izingxenye zixhunywe ochungechungeni, futhi ukusebenza kahle kwesistimu kuzoncishiswa uma i-voltage iphansi kakhulu.
(10) Amandla weswishi ye-AC exhunywe kugridi yesikhungo samandla se-PV mancane kakhulu ukuze ahlangabezane nezimfuneko zokuphuma kwe-inverter.
