I-MPPT vs. PWM: Yisiphi isilawuli esilungele ukukhanya okuphuzi okukhanyayo kwelanga?

Emkhakheni wezixazululo zelanga,izibani ezikhanyayo zelanga eziphuzisezibe yingxenye ebalulekile yezinhlelo zokusebenza ezahlukahlukene okuhlanganisa ukuphathwa kwethrafikhi, izindawo zokwakha, kanye nezimpawu eziphuthumayo. Njengomhlinzeki onolwazi wezibani ezikhanyayo zelanga eziphuzi, i-Qixiang iyaqonda ukubaluleka kokukhetha isilawuli esifanele ukuze ithuthukise ukusebenza kwalezi zibani. Kunezinhlobo ezimbili eziyinhloko zezilawuli zokushaja zelanga ezivame ukusetshenziswa ezinhlelweni zelanga: Ukulandelela Okukhulu Kwamandla (MPPT) kanye Nokuguquguquka Kobubanzi Be-Pulse (PWM). Lesi sihloko sizogxila emehluko phakathi kwezilawuli ze-MPPT kanye ne-PWM futhi sikusize unqume ukuthi yisiphi isilawuli esilungele izidingo zakho zokukhanya okukhanyayo kwelanga okuphuzi.

Funda ngezilawuli zokushaja zelanga

Ngaphambi kokuqhathanisa, kubalulekile ukuqonda ukuthi isilawuli sokushaja selanga senzani. Lawa madivayisi alawula i-voltage kanye nomsinga kusuka kumaphaneli elanga kuya ebhethri, okuqinisekisa ukuthi ibhethri lishajwa kahle nangokuphephile. Ukukhetha isilawuli kungathinta kakhulu ukusebenza kanye nobude besistimu yakho yokukhanya okuphuzi okukhanyayo kwelanga.

Abalawuli be-PWM

Izilawuli ze-pulse width modulation (PWM) ziyindlela evamile yokulawula ukushaja kwe-solar. Zisebenza ngokuxhuma iphaneli ye-solar ngqo ebhethrini nokusebenzisa uchungechunge lwezimpawu zokushintsha ukulawula inqubo yokushaja. Ububanzi besignali "yokuvula" buyalungiswa ngokusekelwe esimweni sokushaja kwebhethri, okuvumela inqubo yokushaja ezinzile nelawulekayo.

Izinzuzo Zabalawuli be-PWM:

1. Kulula Futhi Kubiza Kakhulu:

Izilawuli ze-PWM ngokuvamile zishibhile futhi kulula ukuzifaka kunezilawuli ze-MPPT. Lokhu kuzenza zibe ukukhetha okukhangayo kumaphrojekthi anakekela isabelomali.

2. Ukuthembeka:

Ngenxa yezingxenye ezimbalwa kanye nemiklamo elula, abalawuli be-PWM bavame ukuba nokwethenjelwa kakhudlwana futhi badinga ukunakekelwa okuncane.

3. Ukusebenza Kahle Ezinhlelweni Ezincane:

Ezinhlelweni ezincane zelanga lapho i-voltage yephaneli yelanga ifana kakhulu ne-voltage yebhethri, ukusebenza kahle kwesilawuli se-PWM kuphezulu kakhulu.

Abalawuli be-MPPT

Izilawuli ze-Maximum Power Point Tracking (MPPT) ziwubuchwepheshe obuthuthukisiwe obuthuthukisa amandla aqoqwe kumaphaneli elanga. Zihlala ziqapha ukuphuma kwamaphaneli elanga futhi zilungise indawo yokusebenza kagesi ukuqinisekisa ukuthi kukhishwa amandla aphezulu.

Izinzuzo ze-MPPT Controller:

1. Ukusebenza Kahle Okuphezulu:

Uma kuqhathaniswa nabalawuli be-PWM, abalawuli be-MPPT bangandisa ukusebenza kahle kwezinhlelo zelanga ngamaphesenti angama-30, ikakhulukazi lapho i-voltage yephaneli yelanga iphakeme kune-voltage yebhethri.

2. Ukusebenza okungcono ezimweni zokukhanya okuphansi:

Isilawuli se-MPPT sisebenza kahle ezimweni zokukhanya okuphansi, okwenza kube kuhle kakhulu ekukhanyeni kwelanga okuphuzi okudingeka kusebenze kahle ngisho nasezinsukwini ezinamafu noma lapho kuhwalala.

3. Ukuguquguquka komklamo wesistimu:

Abalawuli be-MPPT bavumela ukuguquguquka okukhulu ekwakhiweni kwesistimu ukusebenzisa amaphaneli elanga ane-voltage ephezulu, okunganciphisa izindleko zokuxhuma kanye nokulahlekelwa.

Yisiphi isilawuli esingcono kakhulu se-solar yellow light flash?

Uma ukhetha izilawuli ze-MPPT kanye ne-PWM zokukhanya okuphuzi kwelanga, isinqumo sincike kakhulu ezidingweni ezithile zesicelo sakho.

- Kumaphrojekthi Amancane, Anesabelomali Esincane: Uma usebenza kuphrojekthi encane enesabelomali esilinganiselwe, isilawuli se-PWM singase sanele. Sithembekile, sisebenza kahle, futhi singanikeza amandla anele ezibani ezikhanyayo eziphuzi zelanga ngaphansi kwezimo ezifanele.

- Ngezinhlelo zokusebenza ezinkulu noma ezidinga kakhulu: Uma iphrojekthi yakho idinga ukusebenza kahle okukhulu, ikakhulukazi ngaphansi kwezimo zokukhanya ezishintshayo, isilawuli se-MPPT siyindlela engcono. Ukusebenza kahle okukhulu kanye nokusebenza kahle ezimweni zokukhanya okuphansi kwenza abalawuli be-MPPT bafaneleke ukuqinisekisa ukuthi izibani zakho ezikhanyayo zelanga eziphuzi zihlala zisebenza ngokwethembeka.

Ekuphetheni

Njengomhlinzeki wezibani ezikhanyayo zelanga eziphuzi othembekile, i-Qixiang izibophezele ekuhlinzekeni ngemikhiqizo esezingeni eliphezulu kanye nesiqondiso sochwepheshe ukukusiza ukuthi ukhethe kahle kakhulu ngelanga. Kungakhathaliseki ukuthi ukhetha isilawuli se-PWM noma se-MPPT, ukuqonda umehluko nezinzuzo zaso ngasinye kungasiza ekukhetheni ikhambi elifanele lesistimu yakho yokukhanya okukhanyayo kwelanga okuphuzi.

Ukuze uthole ikhotheshini eyenzelwe wena noma usizo olwengeziwe ekukhetheni okulungileisibani esikhanyayo selanga esiphuzi kanye nesilawuliNgephrojekthi yakho, sicela ukhululeke ukuxhumana neQixiang. Silapha ukukunikeza izixazululo zelanga ezithembekile zokukukhanyisa indlela yakho!
