Kwakhiwa kwezinhlayiya zolawulo lwesithuthi, ukukhetha inkokheli yesithuthi kuyafana nokukhetha izihlangothi. Okunye kukukhetha ukusebenzisa ibhatere AC-coupled noma DC-coupled. Ngenkathi zombili zagcina isithuthi ukuze sisetshenzise kamva, eyodwa kuzo ihlangana nesistimu yakho ngendlela eyahlukene, okungaba khona kubangela imiphumela, into yokuqashisa, nezidingo. Uma izilimi ezilandelwayo ziyathintela njengoba zingachazeki, ungahlupheki; ilonke elaziwayo lizochaza izimpawu ezibalulekile ngendlela ephambene kakhulu futhi izokunika izimbono ezisuselwa emehlweni yempilo yokuphila ukuze ungene kuthini okungcono kakhulu kusimo sakho.
Ukubuka ngokujwayelekile: Yiziphi i-AC-Coupled ne DC-Coupled Systems?
Izinhlelo ezihlanganisa i-AC nezinhlelo eziqashelwa nge-DC zinezinhlelo ezahlukene zokuxhuma izithuthi ze-solar kumagazini, ngokuphelele ngendlela yokuguquguquka kwezimali. Izithuthi ze-solar zakhula amandla e-DC enguqukiswa ku-AC engasetyenziselwa emakhaya. Kuzinhlelo eziqashelwe nge-DC, izithuthi ihlawula DC ngqo kumagazini ngapha kohlelo lokulawula ukulayisha, futhi iguquke kuphela ku-AC uma kusetshenziswa amandla—susa into ekudingeka ukuguquka amandla amandla wezocingo le-DC. Kodwa, inhlelo eziqashelwe nge-AC iguquka i-DC ngokushesha ku-AC, emuva ku-DC ukugcina kanti emuva ku-AC ukusebenzisa. Ayikho yini efanelekile kodwa iyinkimbinkimbi. Ngokomzekelo, uma umuntu onekhabinithi sele ayifuna ukufaka amagazini ngaleso simo, kuzosimama ngcono ukusebenzisa ukuxhunywa kwe-AC. Kodwa, lapho kubhekene nomuntu ohlelayo indlu entsha engaphandle kwegridi, ukuxhumanisa nge-DC ngokuvamile kungumugqa ofanele ngoba uyisiseko, kanye nokuthatha amandla angaphansi.
Iindlela ebalulekileyo kwi-installation kunye nesakhelo sistimu
Izinhlelo zasolari eziholiselwe k-AC ne DC azidlula kuphela ukuthi zifaka amandla ngendlela ethile kodwa futhi kuhlangabezana ngezibopho nezinhlelo. Izinhlelo eziqashelwe k-DC zingakwazi ukuwona okunjalo uma konke kuyakhiwa ngasinye isikhathi, njengoba amapaneli, ikholisi lokulayisha, ibethiri, ne-inverter zihlanganiswa, kunezinkinga ezimbalwa yokuguquguquka kanye nezwire ekushiswe. Lokhu kwenza kube yisimo esihle kuzindlu ezingaphandle kwegrid noma emabhukhankhini amasha aphathelene nokusebenza nokunakekelwa. Ngokuphambene, izihlengahlenga kahle kunezinhlelo eziqashelwe k-AC. Noma kunjalo, ukuvuselela i-inverter esikhona ukufakwa kwebethiri akudingi ukubuyekezela konke isistemu, kodwa ngokuvamile kudinga uhlelo oluthe addisionali, i-inverter ezimbili ezihlanganiswe ngokulandelana, izwire ezintsha, kanye nomthubi ongezayo nokunakekela.
Lapho Kufanele Ukhethe Ingcako Eziqashelwe k-DC Ukuze Ufakhe Isimo Esiphakeme
Isistemu esihliwe nge-DC yisistimu esihle kakhulu. Ngoba amandla asekhona ku-DC kambe akusetshenziswa, kukhona ukungahlelekwa kwamandla futhi amabhethri achashazeka ngendlela efanele. Isetshenziselwa emakhayeni angaphandle komnyango womqoka nezindlu, kanye namathuba apho konke okwawo kubalwa, futhi kudinga ukulungiswa okuncane. Nakhu kuncike kakhulu ekugcineni ubomi bokuchashazeka kwebhethri. Isistemu ye-DC esisetshenziswayo endlini yasekhaya engaphandle kakhulu iyakuvumela izipliyi ukuchashaza amabhethri ngokudla ngaphandle kokungahlelekwa okuningi, ukusebenzisa konke okukhokhelwe kaningi nangoba ngeminyaka engaqondeni noma ngemvula.
