Sisebenza Kanjani Isilawuli Seshaja Yelanga?

Siyini isilawuli se-solar charge?
Njengengxenye ebalulekile yohlelo lwamandla avuselelekayo, izilawuli zokushaja zisebenza njengezilawuli zamanje kanye nezamandla kagesi, zivikela ibhethri ekushajweni ngokweqile.Inhloso yabo ukugcina amabhethri akho e-deep-cycle eshajwe kahle futhi ephephile ngokuhamba kwesikhathi.Izilawuli zokushaja zelanga ziyadingeka ukuze kushajwe okuphephile nokusebenza kahle kwamaseli elanga.Cabanga ngesilawuli sokushaja njengesilawuli esiqinile phakathi kwephaneli yakho yelanga namaseli akho elanga.Ngaphandle kwesilawuli sokushaja, iphaneli yelanga ingaqhubeka nokunikeza amandla ebhethri ngaphezu kwephoyinti lokushajwa eligcwele, okuholela ekulimaleni kwebhethri kanye nezimo ezingaba yingozi.

Yingakho izilawuli zokushaja zibaluleke kakhulu: Amaphaneli elanga amaningi angu-12-volt akhipha ama-volts angu-16 ukuya kwangu-20, ukuze amabhethri ashajwe kalula ngaphandle kwanoma yisiphi isimiso.Amaseli elanga amaningi angu-12-volt adinga ama-volts angu-14-14.5 ukuze afinyelele ukushajwa okuphelele, ukuze ukwazi ukubona ukuthi izinkinga zokushajwa ngokweqile zingenzeka kanjani.
Ukusebenza kwe-Solar Charge Controller
Ukusebenza kwesilawuli seshaja yelanga kuzungeza ekulawuleni ngempumelelo inqubo yokushaja ukuze kuqinisekiswe impilo nempilo ende yephakethe lebhethri.Okulandelayo incazelo enemininingwane yokusebenza kwayo:

Amamodi Wokushaja: Isilawuli sokushaja selanga sisebenza ngezindlela zokushaja ezihlukene ukuze sivumelane nesimo sokushajwa kwebhethri.Izigaba ezintathu zokushaja eziyinhloko yinqwaba, ukumuncwa, kanye nokuntanta.Phakathi nesigaba sokushaja ngobuningi, isilawuli sivumela umkhawulo wamanje ukuthi ugeleze kubhethri, siyishaje ngokushesha.Phakathi nesigaba sokumuncwa, isilawuli sokushaja sigcina i-voltage engashintshi ukuvimbela ukushajwa ngokweqile futhi kancane kancane siletha ibhethri kumthamo ogcwele.Okokugcina, phakathi nesigaba sokuntanta, isilawuli sokushaja sinikeza amandla kagesi aphansi ukuze kugcinwe ibhethri lishajwe ngokugcwele ngaphandle kokukhipha igesi ngokweqile noma ukulahlekelwa amanzi.

Ukulawulwa Kwebhethri: Isilawuli sokushaja sihlala siqapha amandla kagesi webhethri ukuze siqinisekise ukuthi ihlala phakathi kwebanga eliphephile.Ilawula amandla okushaja ngokwesimo sokushajwa kwebhethri ukuvimbela ukushajwa ngokweqile noma ukuchithwa okujulile, okungalimaza ibhethri.Isilawuli sokushaja sithuthukisa ukusebenza kwebhethri futhi sandise impilo yaso ngokulungisa ngobuhlakani amapharamitha wokushaja.

I-Maximum Power Point Tracking (MPPT): Esimeni sesilawuli sokushaja se-MPPT, amandla engeziwe aqala ukusebenza.Ubuchwepheshe be-MPPT buvumela isilawuli ukuthi silandelele futhi sikhiphe amandla amakhulu kuhlu lwamaphaneli elanga.Ngokuhlala ulungisa i-voltage yokusebenza kanye neyamanje ukuze kutholwe indawo enkulu yamandla ephaneli, isilawuli se-MPPT siqinisekisa ukuguqulwa kwamandla okuphumelelayo kanye nokusebenza kahle kokushaja okuphezulu, ikakhulukazi uma amandla kagesi elanga ehluka ngokwezimo zemvelo.
Isiphetho

Ukuqonda ukuthi izilawuli zeshaja yelanga zisebenza kanjani kanye nokubaluleka kwazo kusistimu yamandla elanga kukuvumela ukuthi wenze izinqumo ezinolwazi lapho ukhetha futhi ufaka isilawuli sokushaja.Ngokucabangela izici ezifana ne-voltage yesistimu, uhlobo lwebhethri, nezidingo zokulayisha, ungakhetha uhlobo olulungile nomthamo wesilawuli sokushaja ngezidingo zakho ezithile.Ukufakwa ngendlela efanele nokugcinwa okuvamile kuzoqinisekisa ukuphila isikhathi eside nokusebenza kahle kwesilawuli sakho sokushaja ilanga, kukhulise izinzuzo zesistimu yakho sonozungezilanga.
Khumbula, izilawuli zokushaja kwelanga zidlala indima ebalulekile ekulawuleni inqubo yokushaja, ukuvikela amabhethri, kanye nokuqinisekisa ukusebenza kahle kwesistimu yakho sonozungezilanga.Bopha amandla amandla elanga ngokuzibophezela nangempumelelo ngokuhlanganisa isilawuli seshaja yelanga esithembekile nesifanelekile.Kungakhathaliseki ukuthi ukhetha isilawuli se-PWM noma se-MPPT, ukuqonda ukusebenza kwaso, izici, nokucatshangelwa kokukhetha kuzokuvumela ukuba wenze ukukhetha okungcono kakhulu kwesistimu yakho yamandla elanga.
