Ukucushwa nokukhethwa kwesilawuli selanga

Ukumiswa nokukhethwa kwesilawuli selanga kufanele kunqunywe ngokuvumelana nezinkomba ezihlukahlukene zobuchwepheshe zesistimu yonke futhi ngokubhekisela kubhukwana lesampula lomkhiqizo elinikezwe umenzi we-inverter.Ngokuvamile, izinkomba zobuchwepheshe ezilandelayo kufanele zicatshangelwe:

1. I-voltage yokusebenza yesistimu

Ibhekisela ku-voltage esebenzayo yephakethe lebhethri kusistimu yokuphehla amandla elanga.Le voltage inqunywa ngokuya nge-voltage yokusebenza yomthwalo we-DC noma ukumiswa kwe-inverter ye-AC.Ngokuvamile, kukhona 12V, 24V, 48V, 110V kanye 220V.

2. Isilinganiso samanje sokufakwayo kanye nenani lamashaneli okokufaka wesilawuli selanga

I-current input elinganiselwe yesilawuli selanga sincike ekufakweni kwamanje kwengxenye yeseli yelanga noma i-array yesikwele.Isilinganiso sokufakwayo samanje sesilawuli selanga kufanele silingane noma sibe sikhulu kunokokufaka kweseli yelanga ngesikhathi sokumodela.

Inombolo yeziteshi zokufaka zesilawuli selanga kufanele ibe ngaphezu noma ilingane neziteshi zokufakwayo zokuklama ze-solar cell array.Izilawuli ezinamandla aphansi ngokuvamile zinokufakwa kohlelo olulodwa lweseli yelanga.Izilawuli zelanga ezinamandla amakhulu ngokuvamile zisebenzisa okokufaka okuningi.Ubuningi bamanje bokufakwayo ngakunye = okufakwayo okulinganiselwe okwamanje/inombolo yamashaneli okokufaka.Ngakho-ke, amandla aphumayo ebhethri ngalinye kufanele abe Ngaphansi noma alingane nenani eliphezulu lamanje elivunyelwe esiteshini ngasinye sesilawuli selanga.

3. Isilinganiso somthwalo wamanje wesilawuli selanga

Okusho ukuthi, i-DC ephumayo yamanje isilawuli selanga esiphuma kumthwalo we-DC noma i-inverter, futhi idatha kufanele ihlangabezane nezidingo zokufaka zomthwalo noma inverter.

Ngokungeziwe kudatha yezobuchwepheshe eshiwo ngenhla ukuze kuhlangatshezwane nezidingo zokuklama, ukusetshenziswa kwezinga lokushisa kwemvelo, ukuphakama, izinga lokuvikela kanye nobukhulu bangaphandle kanye neminye imingcele, kanye nabakhiqizi nemikhiqizo.
