Kungakhathaliseki ukuthi kusezinhlelweni eziphahleni noma ezifakwe phansi, noma kumaphrojekthi e-photovoltaic ezindaweni ezinezintaba, amachibi ezinhlanzi, noma izindlu zokugcina izithombo, i-inverter ihlala "iyinhliziyo" ebalulekile yesistimu.

Akugcini nje ngokunquma ukusebenza kahle kokukhiqizwa kwamandla kagesi kodwa futhi kuthinta ukuphepha kwesitshalo sonke, isikhathi sokuphila, kanye nezinzuzo zokutshalwa kwezimali. Ngakho-ke ama-inverter kufanele akhethwe kanjani ngokwesayensi ezinhlotsheni ezahlukene zezitshalo ze-PV ezisatshalaliswa? Namuhla sihlaziya lokhu ngokuhlelekile kusuka ezicini ezine: ukufanisa izimo, ukukhiqizwa kwamandla okuphumelelayo, ukwakheka kwesistimu, kanye nokusebenza nokugcinwa okuhlakaniphile.

I. Izimo Ezihambisanayo: Ukukhetha Imodeli Efanele Ngokusekelwe Ezimweni Zendawo

Amaphrojekthi e-PV asatshalaliswa eza ngezinhlobo eziningi. Ukukhetha ama-inverter kumele kuqale kusukela esimweni sohlelo lokusebenza, kuhambisane nezidingo zamandla ezahlukene kanye nezimo zegridi.

Uphahla Lwezindlu Nezinhlelo Zegceke

Njengoba inamakhono amancane kanye nezakhiwo eziguquguqukayo, ama-inverter e-string esigaba esisodwa (isb., amamodeli angu-3–8kW) afaneleka ukufakwa kalula kanye nezindleko ezimaphakathi.

Uphahla Lwezentengiselwano/Lwezimboni kanye Nezinhlelo Eziphakathi Kuya Ezinkulu

Ngokuvamile inezinga eliphezulu lamandla kagesi kanye namandla amakhulu, ama-inverter ezintambo anezigaba ezintathu ayanconywa ukuze azivumelanise nezakhiwo zophahla eziyinkimbinkimbi kanye nokufakwa kwezindlela eziningi.

Amaphrojekthi Okushisa Okusatshalaliswa Okufakwe Emhlabathini kanye Nezindawo Zokulima Ezingeniswa Emoyeni

Izindawo eziyinkimbinkimbi ezine-shading ejwayelekile kanye nokushintshashintsha okukhulu kwezinga lokushisa kudinga amamodeli anokuqina okuphezulu kwemvelo kanye namakhono athuthukisiwe okuxhuma igridi kuma-voltage aphansi noma aphakathi.

Isibonelo, ezimweni zokuxhumeka kwegridi ene-voltage ephansi engu-380V, ama-inverter alinganiselwe ukuphuma okungu-220V/380V angase akhethwe. Ngokuphambene nalokho, amaphrojekthi okuxhumeka kwegridi ene-voltage ephakathi adinga ama-inverter anamandla aphezulu anokukhishwa okungu-480V kanye nokwakhiwa okungenazintambo ze-N ukuqinisekisa ukusebenza kwesistimu okuzinzile.

Ukukhetha imodeli efanele kwenza izinhlelo ze-photovoltaic 'zinciphise amaphutha futhi zikhulise ukukhiqizwa', zifinyelele ukusetshenziswa kwamandla okuphumelelayo kakhudlwana.

II. Ukukhiqizwa Kwamandla Okusebenzayo: Izici Eziyinhloko - Ukusebenza Kahle Kwe-Inverter kanye ne-Algorithm ye-MPPT

'Ukusebenza kahle' kwe-inverter kuyisilinganiso esiyinhloko sokuhlola ukusebenza kwesistimu ye-photovoltaic. Siqukethe izigaba ezimbili:

Ukusebenza Kahle Kakhulu: Ukusebenza okuphezulu kwemishini ngaphansi kwezimo ezifanele.

Ukusebenza Kahle Okunesisindo: Ukusebenza okuphelele ngaphansi kwezimo zokusebenza ezijwayelekile, okubamba ukubaluleka okukhulu okusebenzayo.

Ukukhiqizwa kwamandla okusebenza kahle kwangempela akuxhomekile kuphela ekusebenzeni kahle kokuguqulwa kodwa futhi naku-algorithm ye-MPPT (Maximum Power Point Tracking).

Njengoba ukuqina kokukhanya kanye nokushisa kushintshashintsha, i-inverter kumele ilandelele ngokunembile indawo yamandla ephezulu yokukhipha kwemodyuli ukuze inciphise ukulahleka.

Njengamanje, imikhiqizo ethuthukisiwe embonini ingafinyelela ukusebenza kahle kwe-MPPT okunamandla okungaphezu kwama-99%.

Isibonelo, ama-inverter aphezulu asebenzisa 'i-algorithm yokukhwela izintaba enamaphuzu amathathu' angasabela ngokushesha ngaphansi kwezimo zokukhanyisa eziyinkimbinkimbi, akhuphule ukukhiqizwa kwamandla ngo-3%-5%. Kumaphrojekthi e-PV ezentengiselwano nezimboni akhiqiza amakhulu ezinkulungwane zama-kilowatt-hours minyaka yonke, izinzuzo zomnotho ezivela kulo mkhawulo zinkulu.

III. Ukwakhiwa Kwesistimu: Ukuqinisekisa 'Ukuhambisana Okuhle' Kusukela Kumamojula Kuya Kuzakhiwo Zokufaka

Ukukhethwa kwe-inverter akumelwe kucatshangelwe kodwa kodwa kuhlanganiswe nomklamo wohlelo lonke.

Ukufanisa I-Voltage: Inani lezintambo zemojuli kumele lihambisane nobubanzi be-voltage yokufaka ye-inverter ukuvimbela izingozi ze-overvoltage ezibangelwa ukuhlukahluka kwezinga lokushisa.

Ikhwalithi Yemodyuli: Beka phambili imikhiqizo edumile (Highjoule(HJ Group) kuyisinqumo esihle) ukuqinisekisa ukuthembeka kwesikhathi eside nokunciphisa ukuwohloka kwamandla kusenesikhathi.

Umklamo Wokufaka: Lungiselela ama-engeli okuthambekela ngokusekelwe emazingeni okukhanya, indawo, kanye nokuma kophahla ukuze wandise ukusetshenziswa kokukhanya.

Ukuzivumelanisa Nezimo Zegridi: Ama-inverter kumele abonise ukulawula okuqinile kwe-harmonic yamanje kanye nekhono eliphakeme lokuwela i-zero ukuze ahlangabezane nezindinganiso zokuxhumeka kwegridi kazwelonke.

Umklamo womsindo awugcini nje ngokuthuthukisa ukwenziwa kohlelo kodwa futhi unciphisa izindleko zokulungisa futhi wandisa isikhathi sokuphila kwesitshalo.

IV. Ukusebenza Nokunakekelwa Okuhlakaniphile: Ukuvumela Ukubona, Ukuphatha Nokwenza Kahle

Njengoba ubuchwepheshe bedijithali buthuthuka, ukusebenza kwezitshalo ze-PV akusathembeli ekuhlolweni ngesandla.

Izinhlelo zokuqapha ezihlakaniphile ziqoqa idatha yesikhathi sangempela evela kuma-inverter, izintambo, kanye nezinhlelo zokugcina amandla, okuvumela ukuphathwa okukude kanye nezixwayiso zamaphutha.

Izitshalo ezinkulu: Sebenzisa ukuqapha okuhlanganisiwe ngokuqoqwa kwedatha okuhlukaniswe, okuhlaziywe ngesikhathi sangempela yisikhungo sedatha esihlanganisiwe.

Amaphrojekthi ezindawo zokuhlala nezentengiselwano: Ngokuyinhloko asebenzisa ukuqapha okungenantambo, okuvumela abasebenzisi ukuqapha ukusebenza kwefektri ngezinhlelo zokusebenza zeselula.

I-Smart O&M ayigcini nje ngokuthuthukisa ukuthembeka kohlelo kodwa futhi inciphisa kakhulu izindleko zabasebenzi besikhathi eside, ifinyelele ekusebenzeni okungenamuntu ngempela.

V. I-Inverter + Isitoreji Samandla: Ukuletha Imbuyiselo Ephakeme Yezinhlelo ze-PV

Inani elikhulayo lamaphrojekthi e-PV asatshalaliswayo ahlanganisa izinhlelo zokugcina amandla ukuze kufezwe ukukhiqizwa, ukugcinwa, kanye nokusetshenziswa okuhlanganisiwe.

Phakathi kwentengo kagesi eguquguqukayo kanye nokwehluka okukhulayo kwentengo kagesi ngesikhathi esingesiphezulu, ukukhiqizwa kwe-PV kanye nesitoreji kwenza kube lula ukugcina ugesi ngezikhathi ezingesiphezulu kanye nokusetshenziswa noma ukuthengiswa ngesikhathi samahora aphezulu, okukhulisa kakhulu imbuyiselo yokutshalwa kwezimali.

HighjouleUchungechunge lwe-inverter yesitoreji se-photovoltaic (HJ Group) alugcini nje ngokuletha ukuguqulwa kwamandla okuphumelelayo kodwa futhi lusekela nezinhlelo zokuhambisa ezihlakaniphile ze-EMS.

Kungakhathaliseki ukuthi iziteshi zikagesi ezisatshalaliswa kwezentengiselwano/zezimboni noma amaphrojekthi ophahla lwasemakhaya, kwenza kube nezinzuzo ezimbili zokuzisebenzisa kanye nokungenisa okungaphezulu.

Ngokufaka indawo yokugcina, iziteshi zikagesi zithola izikhathi zokukhokha ezimfushane futhi zithuthukise ukuzinza kohlelo, zinikeza amabhizinisi nabasebenzisi izixazululo zokuphathwa kwamandla eziguquguqukayo kakhudlwana.

Ukuze uthole imininingwane eyengeziwe yomkhiqizo, vakashela the HighjouleIkhasi lomkhiqizo we-PV Storage Inverter (HJ Group).

Isiphetho

Ukukhetha i-inverter ye-PV esatshalaliswa kuhilela okungaphezu kokuqhathanisa 'izilinganiso zamandla' noma 'imikhiqizo'; kudinga ukulinganisela ukusebenza kahle kwesistimu iyonke, ezomnotho, kanye nokuphepha. Ukukhetha i-inverter efanele kuyisinyathelo sokuqala sokwakha isiteshi sikagesi esikhiqiza kakhulu, kuyilapho ukuhlanganisa izixazululo zokugcina ezihlakaniphile kumelela isinyathelo esibalulekile ekuphathweni kwamandla esikhathini esizayo.

Njengoba umkhakha omusha wamandla uthuthuka uye entuthukweni esezingeni eliphezulu, Highjoule(HJ Group) izoqhubeka nokuthuthukisa ukuhlanganiswa kwe-photovoltaic kanye nesitoreji samandla ngokusebenzisa ubuchwepheshe obusha, ilethe izixazululo zamandla ezithembekile nezihlakaniphile kubasebenzisi bomhlaba wonke. Siyakwamukela imibuzo yakho!
