Indlela yokukhetha inverter ye-photovoltaic yasendlini

Njengoba ama-photovoltaics angena ezindlini eziningi, abasebenzisi abaningi basekhaya bazoba nombuzo ngaphambi kokufaka ama-photovoltaics: Hlobo luni lwe-inverter okufanele balukhethe?

Lapho ufaka ama-photovoltaics asekhaya, izici ezilandelayo ze-5 yizo okufanele uzicabangele:

01

ukwandisa imali engenayo

Yini i-inverter? Kuyidivayisi eguqula amandla e-DC akhiqizwa amamojula elanga abe amandla e-AC angasetshenziswa izakhamuzi. Ngakho-ke, ukusebenza kahle kokuguqulwa kokukhiqizwa kwamandla kuyindaba ebaluleke kakhulu lapho uthenga i-inverter. Njengamanje, sekuphenduke inkambiso evamile ukuthi imindeni yasekhaya isebenzise amandla aphezulu kanye nezingxenye zamanje .Ngakho-ke, amakhaya kufanele acabangele kuqala ama-inverters aguqulelwe ezingxenyeni zamanje eziphezulu, ezinokusebenza okuphezulu kokuguqulwa kanye nezindleko eziphansi.

Ngaphezu kwalokho, kunezinkomba ezimbalwa ezibalulekile zokuqhathanisa:

Ukusebenza kahle kwe-inverter

Ukusebenza kahle okuphezulu kanye nokusebenza kahle kwe-MPPT kwe-inverter yizinkomba ezibalulekile zokucabangela ukukhiqizwa kwamandla kwe-inverter. Uma kuphakeme ukusebenza kahle, amandla okukhiqiza amandla anamandla.

Ububanzi be-voltage yokusebenza kwe-DC

Ububanzi bobubanzi be-voltage esebenzayo ye-DC, okusho ukuqala kwangaphambi kwesikhathi nokumiswa sekwephuzile, isikhathi sokukhiqiza amandla siba side, kulapho ukukhiqizwa kwamandla kuyanda.

Ukunemba kobuchwepheshe bokulandelela i-MPPT

Ubuchwepheshe bokulandelela be-MPPT bunokunemba okuphezulu, impendulo eguquguqukayo esheshayo, bungavumelana nezinguquko ezisheshayo ekukhanyeni, futhi buthuthukise ukusebenza kahle kokukhiqizwa kwamandla.

02

Ukuzivumelanisa nezimo

Imvelo yeziteshi zikagesi zasendlini iyinkimbinkimbi. Izinkinga ezifana namatheminali egridi yamandla asemaphandleni kanye nokusetshenziswa kwamandla kuzodala i-inverter AC overvoltage, undervoltage namanye ama-alamu. I-inverter idinga ukwesekwa kwegridi okubuthakathaka, ububanzi begridi ye-voltage evumelana nezimo, kanye nokuncipha kwe-overvoltage. , isinxephezelo samandla asebenzayo kanye neminye imisebenzi yokunciphisa ama-alamu amaphutha. Inani lama-MPPT futhi lingenye yezinkomba ezibalulekile okufanele zibhekwe:ukucushwa kwe-MPPT yamashaneli amaningi kungahlelwa ngokuguquguquka ngokuya ngezici ezifana nokuma okuhlukile, uphahla oluhlukene, kanye nokucaciswa okuhlukile kwezingxenye.

03

ukufakwa lula

Amamodeli amancane nalula kulula ukuwafaka. Ngesikhathi esifanayo, kufanele ukhethe i-inverter esungulwe efektri ngaphambi kokushiya imboni. Ngemva kokuthi ifakwe ekhaya lomsebenzisi, ingasetshenziswa ngemva kokukhanyisa, okonga isikhathi sokulungisa iphutha futhi kulula kakhulu.

04

iphephile futhi izinzile

Njengoba ama-inverter amaningi efakwe ngaphandle, izinga le-IP elingangeni manzi kanye nelokuvikela uthuli liyinkomba yokuvikela engakwazi ukushaywa indiva, engavikela ngempumelelo i-inverter emiphumeleni eyingozi ezindaweni zesimo sezulu esibi.Khetha i-inverter ene-IP65 noma ngaphezulu ukuzeqinisekisa ukuthi i-inverter isebenza ngokujwayelekile.

Mayelana nemisebenzi yokuvikela, ngaphezu kwemisebenzi edingekayo efana nokushintsha kwe-DC, ukuvikelwa kokufakwa kwe-overvoltage, ukuvikelwa kwesekethe emfushane ye-AC, ukuvikela okuphumayo kwe-AC, nokuvikela ukumelana nokufakwa kwe-insulation, kuneminye imisebenzi emithathu ebaluleke kakhulu:

#

I-DC arc ehlakaniphile yokuthola i-AFCI

Ingakwazi ukubona ngokunembile amasignali e-arcing, ivale ngokushesha, igweme umlilo, futhi ivikele ukuphepha komsebenzisi.

#

Umsebenzi wokuqopha iphutha

Bheka futhi urekhode ama-voltage namagagasi amanje ohlangothini lwe-AC lwe-inverter ngesikhathi sangempela ukuze uthole izinkinga ngokushesha.

#

I-Smart IV Ukuskena kanye Nokuxilongwa

Ingathola ngokunembile amaphutha eyunithi yezinhlamvu futhi ithole izinkinga ngokuqhubekayo. Ngeziqinisekiso eziningi, isiteshi sikagesi singasebenza ngokuzinzile, sinikeze abasebenzisi ukuthula kwengqondo.

05

Ukuphathwa Okuhlakaniphile

Esikhathini samanje sedijithali, amadivaysi ahlakaniphile angahlinzeka abasebenzisi ngokunethezeka okwengeziwe. Inverter brandifakwe inkundla yokuphatha ehlakaniphilesingaletha ukunethezeka okukhulu kubasebenzisi ekuphathweni kwesiteshi sikagesi: Okokuqala, ungasebenzisa i-smartphone yakho ukuze ugade isiteshi sikagesi, uhlole idatha yokusebenza kwesiteshi sikagesi noma nini nanoma kuphi, futhi uqonde isimo sesiteshi sikagesi ngesikhathi. Ngesikhathi esifanayo, abakhiqizi bangathola izinkinga ngokuxilonga bekude, bahlaziye izimbangela zokwehluleka, banikeze izixazululo, futhi baxazulule izinkinga bekude ngesikhathi.
