Iyini i-Solar Hybrid Inverters?

丨Iyini i-Solar Hybrid Inverters?

Kuyidivayisi eguqula amandla e-DC amaphaneli elanga abe ugesi we-AC ukuze kuthuthukiswe ukusetshenziswa kwawo ezindlini zethu nasemabhizinisini. I-crucial power flow management system (PFMS) kuzo ilawula ukuhamba kwamandla phakathi kwamaphaneli elanga, amabhethri namandla egridi. I-PFMS ithumela ugesi oweqile, uma ukhona, okhiqizwe amaphaneli elanga ebhange lebhethri ukuze ugcinwe.

Uma ibhange lebhethri selishajwe ngokugcwele lolu hlelo luthumela ugesi oweqile kugridi. Futhi, phakathi nokucisha kukagesi, i-PFMS ishintshela ebhange lebhethri ukuze inikeze amandla ayisipele. Ngakho-ke, lawa ma-inverters aklanyelwe ukusebenza ngokubambisana namaphaneli elanga, amabhethri, namandla egridi ukuze kuqinisekiswe ukusebenza kahle nokuthembekile kwesistimu yamandla elanga.

Izinhlobo zeHybrid Solar Inverters

1  I-Grid-Tie Hybrid Inverters: Lawa ma-inverter ahlanganisa kalula amandla elanga kanye nogesi wegridi, ethuthukisa ukuhamba kwamandla phakathi kwamaphaneli, amabhethri, kanye negridi kuyilapho enciphisa izikweletu zikagesi ngokusebenzisa i-net metering.

2  Iziguquli zegridi ezinekhophi yasenqolobaneni yebhethri: Asetshenziswa kumasistimu elanga ayingxubevange axhunywe kugridi futhi anamabhethri njengomthombo wamandla oyisipele. Ngazo singasebenzisa amandla agciniwe avela kumabhethri ngesikhathi sokucisha kukagesi noma ngezikhathi zokudingeka kakhulu kukagesi. Bangakwazi ukushintsha kalula phakathi kwamandla egridi namandla ebhethri njengoba kudingeka, banikeze ukunikezwa kwamandla okuthembekile nokungaphazanyiswa.

Ama-inverter e-solar e-Hybrid anezici ezihlukahlukene ezithuthukisa ukusebenza kwazo nokuphila isikhathi eside. Ezinye zalezi zici zichazwe ngezansi:

·   Isistimu yokuphatha ibhethri: Ithuthukisa ukushajwa nokushajwa kwamabhethri, okunweba ubude bawo bempilo futhi iqinisekise ukushajwa okusebenzayo.

·  Isilawuli sokushaja se-MPPT: Isiza ekukhipheni amandla aphezulu kumaphaneli elanga futhi iwadlulisele kumabhethri ekugcineni isize ekwenzeni ngcono ukushajwa kwebhethri.

·  Isistimu yokulawula ukugeleza kwamandla: Njengoba kuchazwe ngenhla, ilawula ukuhamba kwamandla phakathi kwamaphaneli elanga, amabhethri, namandla egridi, iqinisekisa ukusebenza kahle kwesistimu nokuvimbela ukumoshwa kwamandla engeziwe.

Ngaphandle kwalezi zinto ezibalwe ngenhla inezinye izinto ezibalulekile njengokugada kude, ukuvikela ukugcwala ngokweqile kanye ne-short-circuit kanye ne-automatic voltage regulation, okuyenza isebenze kahle kakhulu futhi ithembeke.

Izinzuzo zeHybrid Inverters

·  Banikeza isixazululo esingabizi kakhulu nesinokwethenjelwa samakhaya namabhizinisi njengoba benciphisa ukuncika emandleni egridi futhi basize ekunciphiseni izikweletu zikagesi.

·  Ukusetshenziswa kahle kwamandla elanga ngokuhlanganisa kokubili amandla egridi nangaphandle kwegridi.

·  Ikhono lokuthengisa amandla engeziwe emuva kugridi, okuholela ezinzuzweni zezezimali ezingaba khona.

·   Ukunwebeka nokuvumelana nezimo, okuvumela ukunwetshwa okulula ukuze kuhlangatshezwane nezidingo ezengeziwe zamandla.

·  Amasistimu wamandla elanga ayingxubevange anikeza nokuzimela kwamandla, njengoba ehlinzeka ngomthombo wamandla oyisipele futhi anciphisa ukuncika emandleni egridi.

Iphuma kuGridi ngeHybrid Inverters

Impela kuyasebenza ukuphuma ngaphandle kwegridi usebenzisa i-hybrid solar inverters. Ku-hybrid solar inverter, njengoba kushiwo ngaphambili, ine-PFMS elawula ukuhamba kwamandla phakathi kwamaphaneli elanga, amabhethri namandla egridi ngaleyo ndlela kuhlanganiswe ukusebenza kwesiguquli selanga esijwayelekile kanye neshaja yebhethri. Amabhethri akusistimu yelanga eyingxube ye-off-grid agcina amandla engeziwe akhiqizwa amaphaneli elanga. La mandla agciniwe angasetshenziswa uma kungekho ukukhanya kwelanga noma ngezikhathi zokufunwa kwamandla aphezulu.

Kubalulekile ukuqaphela ukuthi ukuphuma kugridi nge-hybrid solar inverter kudinga ukuhlela ngokucophelela nokucatshangelwa kwezidingo zakho zamandla. Ngakho-ke, ngokuvamile kunconywa ukuthi uthintane nesifaki sonozungezilanga esichwepheshile noma unjiniyela ukuze aklame futhi asebenzise isistimu yelanga engaphandle kwegridi eklanyelwe izidingo zethu ezithile.

Amanye ama-Drawbacks we-Hybrid Inverters

·  Izindleko: I-Hybrid inverters yelanga ingabiza kakhulu kuneziguquli ezijwayelekile zelanga.

·  Ubunzima: Ama-inverters e-solar Hybrid adinga izintambo ezengeziwe nokuxhumeka, okwandisa ubunzima besistimu.

·  Ukusebenza kahle: Ama-inverter e-solar e-Hybrid angase abe nokusebenza kahle okuphansi kancane uma kuqhathaniswa nama-inverter azinikele elanga.

·  Ukugcinwa nokuqapha: Iziguquli ze-solar ezixubile ezinamabhethri zidinga ukunakekelwa okujwayelekile kanye nemizamo yokuqapha.

·  Ubunkimbinkimbi bomklamo wesistimu: Ukuklama isistimu ye-off-grid ene-hybrid solar inverter kungaba inselele futhi kudinga ukucatshangelwa ngokucophelela.

Naphezu kwalezi zingqinamba, i-hybrid inverters ye-solar iyaqhubeka nokukhetha okuthandwayo kumasistimu elanga angaphandle kwegridi kanye ne-hybrid solar ngenxa yekhono labo lokuhlanganisa ukukhiqizwa kwamandla elanga nokugcinwa kwamandla.
