Izilawuli zetshaja yelanga okanye izilawuli zizixhobo ezisetyenziswa kwizibane ezisebenza ngelanga ukulawula umbane ohamba ukusuka kwiphaneli yelanga ukuya kwibhetri. Izilawuli zelanga nazo zinoxanduva lokunciphisa umbane otsalwa yibhetri ukuya kwi-LED. Kwinkqubo yokukhanyisa yelanga, izilawuli zidlala indima ebalulekileyo ekulawuleni itshaja kunye nevolthi. Xa iiphaneli zelanga ziyeka ukuvelisa umbane ekutshoneni kwelanga, izilawuli zinceda ekujikeni i-LED.
Kukho ithuba lokuba umbane ubuyele umva usuka kwibhetri uye kwiipaneli xa kungekho mbane uphumayo ebusuku, nto leyo enokwenzakalisa ubomi beebhetri. Abalawuli betshaja banceda ekuthinteleni ukuhamba kwamandla okubuyela umva ngokufumanisa xa kungekho mbane uphumayo kunye nokukhupha iipaneli kwiibhetri ukuze kuthintelwe ukutshaja kakhulu. Ukutshaja kakhulu kunokunciphisa ubomi beebhetri kwaye abalawuli betshaja banamhlanje banceda ekwandiseni ubomi bebhetri ngokunciphisa ubungakanani bombane osetyenziswa kwibhetri xa itshajiwe ngokupheleleyo kwaye banceda ekuguquleni i-voltage engaphezulu ibe yi-amperage.
Kutheni kufuneka abalawuli kwizibane zelanga?
● Ukulawula i-voltage yebhetri
●Ukuthintela ukuhamba komsinga obuyela umva
●Ukuphepha ukutshaja kakhulu nokutshaja ngaphantsi kweebhetri
●Ukubonisa xa ibhetri itshajwa
Iintlobo zezilawuli zetshaja yelanga
Abalawuli bokutshaja bePulse Width Modulation (PWM)
I-PWM yeyona controller isetyenziswa kakhulu njengoko isebenzisa iteknoloji evavanyiweyo ukulawula ukuhamba kwamandla ombane. Ukuguqulwa kobubanzi bepulse kwenzeka xa ibhetri ifikelela kwinqanaba lokutshaja elilinganayo ngokunciphisa amandla ombane kancinci kancinci. Ukuzikhupha ngokwayo yingxaki eqhelekileyo kwiibhetri ezininzi ezinokutshajwa kwakhona apho zihlala zilahlekelwa ngamandla xa sele zitshajwe ngokupheleleyo. Isilawuli se-PWM siqala kwakhona ukubonelela ngamandla amancinci rhoqo ukuze sigcine itshaja igcwele kwaye sigcine itshaja, ngaloo ndlela siphephe ukuzikhupha ngokwayo.
Izilawuli zePWM zithathwa njengezihlala ixesha elide kwaye zisebenza kakuhle kwiindawo ezishushu. Zibiza kancinci kwaye ziyafumaneka ngobukhulu obahlukeneyo kwiindlela ezahlukeneyo zokusebenza. Ngezilawuli zePWM, kubalulekile ukuba neephaneli zelanga kunye neebhetri ezineevolthi ezifanayo. Isilawuli setshaja sePWM sisilawuli setshaja esiqhelekileyo esisetyenziswa ekukhanyeni kwesitalato selanga kwaye sikwafanelekile kwiinkqubo zelanga ezincinci ezineephaneli ezincinci kunye nebhetri.
Izilawuli zokutshaja ze-Maximum power point tracking (MPPT)
Ii-controllers ze-MPPT ziyindlela ebiza kakhulu neyinkimbinkimbi kwiinkqubo zelanga; nangona kunjalo, enye yezona nzuzo zinkulu zezi zi-controllers ayifani nee-controllers ze-PWM, ii-controllers ze-MPPT zinokulinganisa ii-voltages ezingahambelaniyo ezivela kwiiphaneli zelanga kunye neebhetri. Indlela esetyenziswa kwii-controllers ze-MPPT intsha evumela iiphaneli ukuba zisebenze kwindawo yazo ephezulu yamandla. Ngenxa yokutshintsha kweqondo lemitha yelanga emini yonke, i-voltage yepaneli kunye nomsinga zinokwahluka. Ii-controllers ze-MPPT zilungisa i-voltage ukuze zivelise amandla aphezulu nokuba imeko yemozulu injani na.
Abalawuli be-MPPT batshaja ngokukhawuleza kwaye bahlala ixesha elide. Bayakwazi ukulungisa igalelo labo ukuze baqalise amandla aphezulu kangangoko kwiiphaneli. Aba balawuli bayakwazi ukutshintsha amandla okukhupha ukuze afane namandla ebhetri. Babonwa besebenza ngcono kwiindawo ezibandayo kwaye bathathwa njengabasebenza kakuhle kunee-PWM controllers.
Ungayikhetha njani isilawuli sokutshaja esifanelekileyo?
Zombini ii-PWM kunye nee-MPPT charge controllers zisetyenziswa kwinkqubo yezibane zesitalato zelanga. Ii-controllers zisebenza njengesixhobo sokukhusela kwaye zikhupha okona kulungileyo kwiyunithi yakho yelanga. Ngokusekelwe kwezi zinto zilandelayo, kufuneka ukhethe i-controller ehambelana ne-voltage yenkqubo yakho yelanga.
