(1) Ngaphambi kokulungiswa, qala ngokunqamula ukuxhumana kukagesi phakathi kwe-inverter negridi, bese unqamula ukuxhumana kukagesi ohlangothini lwe-DC. Kuyadingeka ukulinda okungenani imizuzu emi-5 noma ngaphezulu ukuvumela ama-capacitor aphezulu kanye nezinye izingxenye ngaphakathi kwe-inverter ukuthi zikhishwe ngokugcwele ngaphambi kokwenza umsebenzi wokulungisa.

(2) Enkambweni yokusebenza kwesondlo, okokuqala, bheka ngokubonakalayo i-inverter ye-PV nganoma yimuphi umonakalo noma ezinye izimo eziyingozi futhi unake i-anti-static enqubweni ethile yokusebenza, kungcono ukugqoka indandatho yesandla ye-anti-static. Naka izimpawu eziyisixwayiso ku-inverter futhi uhlole ubuso be-inverter ngemva kokupholisa. Ngesikhathi esifanayo ukugwema ukuthintana okungadingekile phakathi kwamabhodi angokwenyama kanye nesifunda.

(3) Ngemuva kokuthi ukugcinwa kuqediwe, qiniseka ukuthi noma yiziphi iziphambeko ezithinta ukusebenza kokuphepha kwe-inverter zisusiwe ngaphambi kokunika amandla ku-inverter.

Imbangela yesigameko:

(1) Ayikho i-voltage ohlangothini lwe-AC lokuphuma kwe-inverter, ukwehluleka kwamandla okusebenza.

(2) Amatheminali okukhipha i-Inverter AC awaxhumekile kahle noma umugqa wetheminali ukhululekile.

Isixazululo:

(1) Sicela usebenzise i-multimeter ukukala i-voltage ye-AC ye-inverter, ngaphansi kwezimo ezijwayelekile amatheminali okukhiphayo kufanele abe ne-voltage yesigaba esingu-380V;

(2) Sicela uhlole ngokulandelana ukuthi ingabe amatheminali awakhululekile yini, ukuthi i-AC circuit breaker ivaliwe noma cha, kanye nokuthi iswishi yokuvikela ukuvuza komhlaba inqanyuliwe yini noma cha.

Imbangela yesigameko: 

I-voltage nemvamisa yegridi ye-AC ingaphandle kwebanga elijwayelekile.

Isixazululo:

(1) Sicela uhlole i-voltage yokuqapha kanye nedatha yomlando wefrikhwensi ukuze uthole ukuthi akhona yini amanani ngaphandle kwebanga lokulawula ukuphepha.

(2) Sicela ulinganise i-voltage yegridi ye-AC nge-multimeter, uma ingavamile ngempela, bese ulinda ukuthi igridi ibuyele kokujwayelekile.

(3)Sicela uhlole okokufaka kwe-DC kanye nokukhishwa kwe-AC kwe-inverter, vumela i-inverter ivuleke isikhathi esingaphezu kwe-30min ukuze ubone ukuthi isifunda sikagesi singatholwa ngokwaso, uma singatholwa ngokwaso, ungaqhubeka nokusisebenzisa, uma singenakutholwa, ungathintana no-Renac ukuze uthole umbiko wokukhanda.

Imbangela yesigameko:

Amamojula amaningi kakhulu axhunywe ochungechungeni abangela amandla kagesi okufakwayo ohlangothini lwe-DC ukuba adlule umkhawulo ophezulu wevoltheji osebenzayo we-inverter.

Isixazululo:

(1)Ngokwezici zokushisa zamamojula we-PV, ukwehla kwezinga lokushisa elizungezile, kuyanda amandla okukhipha amandla. Kunconywa ukuthi ulungiselele ububanzi be-voltage yezintambo ngokuya ngemininingwane yedatha ye-inverter.

(2) Kulolu hlu olujwayelekile lwe-voltage ye-inverter, ukusebenza kahle kwe-inverter kuphezulu, futhi inverter isengakwazi ukugcina isimo sokuphehla 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 shaqa.

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!

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 iklanywe futhi ifakwe ngamandla alinganayo, uma kuphela ixhunywe esikhumulweni se-MPPT sendlela eyodwa, amandla okukhiphayo 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.

Imbangela yesigameko:

Isizathu salokho ukushintshwa kwesistimu ye-invertervala.

Isixazululo:

(1) Cindezela inkinobho yokuqinisekisa isikrini esishintshashintshayo ukuze ufake imenyu enkulu – “SysSwitch”.

(2) Setha “SYS Shintshela” kokuthi “Vula” bese ucindezela ubambe inkinobho yokuqinisekisa.

Imbangela yesigameko:

(1)TI-voltage ye-PV yokufaka ayifinyeleli ekuqaleni okuncane-phezuluI-voltage ye-inverter.

(2)Timitha ayixhunyiwe kwintambo yokuxhumana noma ukuxhumana kunephutha.

(3) I-inverter ayixhunyiwe kumitha, kodwa imitha inikwe amandla kumenyu ye-inverter.

Isixazululo:

(1)Sicela check ukuthi i-voltage yokufaka ye-inverter PV ifinyelela ekuqaleni okuncane-phezuluI-voltage ye-inverter.

(2)Sicela check ukuthi imitha ifakiwe noma cha, uma kungenjalo, udinga "Khubaza" umsebenzi wemitha kumenyu ye-inverter. Umnyango “Ukusetha”-“Okuthuthukile”-”Isici” – “Ukusetha Imitha”. Setha okuthi “Disable” kokuthi “Meter Setting”

(3)Sicela check uma ikhebula lokuxhumana lemitha lixhunywe ngendlela efanele (RS485-A kanye ne-RS485-B axhunywe ngendlela efanele). Uma ukuxazulula inkinga okungenhla KULUNGILE kodwa inkingahlala, sicela uzame ukushintsha imitha.

Incazelo Yephutha:

I-inverter ayilazi ibhethri, ayikwazi ukufunda i-SOC yebhethri, kanye ne-ibhethri SOC umbukisos “N/A”.

Imbangela yesigameko:

(1) Ukwehluleka kokuxhumana kwe-BMS phakathi kwe-inverter nebhethri.

(2) Amabhethriis ayivuliwe noma ukwehluleka kwe-BMC.

(3) Ibhethriis akufanisiwengei-inverter.

(2)Sicela check umaShintshanisa amasheya DIPisethwe kahle ku-i-inverter. Tikheli lakhe lokuxhumana kumele limiswe ngendlela efanele ukuze isiguquli kanye nebhethri kuxhumane kahle. Ngezansi kunomdwebo we-dip switch yekheli lokuxhumanaI-BMC:

(3)Sicela chekifibhethriI-BMC LEDis ukukhanya okuluhlaza.

(4)If iBMCingase ibe nephutha.Sicela uzameezoshintshwa.

Imbangela yesigameko:

(1)I-inverter ayixhunyiwe kumitha kodwa imitha ivumela i-inverter isethwe ku-inverter

(2)Izintambo zokuxhumana ngamamitha i-RS485-A kanye ne-RS485-B zixhumeke ngokungalungile.

Isixazululo:

(1)Sicela check imithaukulungiselelwa, uma kungenjalouxhumano, ngicela usethe"Khubaza" umsebenzi wemitha ku-inverter.

Faka "Isici" - "Ukusetha Imitha". Setha "Khubaza" ku-"Meter1Ukusetha”

(2)If imitha isivele ifakiwe, hlola ukuthi ikhebula lokuxhumana lemitha lixhunywe ngendlela efanele (RS485-A kanye ne-RS485-B ixhunywe ngendlela efanele).

(3)If konke ukuxazulula inkinga KULUNGILE kodwa inkingahlala, sicela uzame ukushintsha imitha.

Imbangela yesigameko:

Lapho isistimu ingenayo i-PV kanye negridi yamandla kuphela, futhiawekho amandla okulayishaimizuzu emi-3, i-inverter ingena ku-Idleimodi, lokhu kuyinto evamile.

Isixazululo:

Ninii-invertercxhuma ku-PVfuthiamabhethri njll.besethola i-inverteris egijima.

Q13:Kungani bi-atteryis ayikhokhisi?

Imbangela yesigameko:
