MPPT vs. Pwm: Yisiphi isilawuli esilungele ukukhanya okukhanyayo okuphuzi kwelanga?

Emkhakheni weSolar Solutions,amalambu aphuzi aphuzi elangaUbe yingxenye ebalulekile yezinhlelo zokusebenza ezahlukahlukene kufaka phakathi ukuphathwa kwethrafikhi, izindawo zokwakha kanye nezimpawu eziphuthumayo. Njengomhlinzeki onolwazi wamalambu aphuzi aphuzi elanga, i-qixiang iyakuqonda ukubaluleka kokukhetha isilawuli esifanele ukwenza kahle ukusebenza kwalawa malambu. Kunezinhlobo ezimbili eziphambili zezilawuli zeSolar Charlimar ezisetshenziswa kakhulu kwizicelo zeSolar: Ukulandelelwa kwamaphoyinti aphezulu (i-MPPT) kanye ne-Pulse Width Modulation (PWM). Le ndatshana izongena ngaphakathi komehluko phakathi kwabalawuli be-MPPT ne-PWM futhi bakusize unqume ukuthi yisiphi isilawuli esingcono kakhulu sokukhanya okukhanyayo okukhanyayo okhanyayo okhanyayo.

Funda mayelana nabalawuli be-solar.

Ngaphambi kokungena ekuqhathaniseni, kubalulekile ukuqonda ukuthi isilawuli secala selanga siyakwenza. Lawa madivaysi alawula ama-voltage futhi akhona avela kumaphaneli elanga ebhethri, aqinisekise ibhethri likhokhiswa kahle nangokuphepha. Ukukhetha kokulawulwa kungathinta kakhulu ukusebenza nokuphila isikhathi eside kohlelo lwakho olukhanyayo olukhanyayo.

Abalawuli be-PWM

Izilawuli ze-Pulse Width Modulant (PWM) ziwuhlobo lwendabuko oluningi lwesilawuli secala lelanga. Basebenza ngokuxhuma iphaneli yelanga ngqo ebhethri futhi basebenzisa uchungechunge lokushintsha amasiginali okulawula inqubo yokushaja. Ububanzi bophawu lwe- "On" luyahlekisa ngokususelwa esimweni sebhethri lokukhokhiswa, okuvumela inqubo yokushaja eqinile nelilawula.

Izinzuzo zabalawuli be-PWM:

1. Elula futhi elibiza kakhulu:

Abalawuli be-PWM ngokuvamile bashibhile futhi kulula ukuwafaka kunezilawuli ze-MPTT. Lokhu kubenza babe yisinqumo esikhangayo samaphrojekthi aqaphela isabelomali.

2. Ukwethembeka:

Ngenxa yezakhi ezimbalwa kanye nemiklamo elula, abalawuli be-PWM bavame ukuthembeka futhi badinga ukulungiswa okuncane.

3. Ukusebenza kahle ezinhlelweni ezincane:

Ngezinhlelo ezincane zelanga lapho i-solar panlel voluble ifana eduze ne-battery voltage, ukusebenza kahle kwesilawuli se-PWM kuphezulu kakhulu.

Abalawuli be-MPT

Ama-Point Point Point Tracking (MPPT) abalawuli athuthukile ngokwengeziwe abangela amandla avunwe amaphaneli elanga. Babheka ngokuqhubekayo ukuphuma kwamaphaneli elanga futhi balungise iphuzu lokusebenza kagesi ukuze baqinisekise ukuthi amandla aphezulu akhishwe.

Izinzuzo Zomlawuli we-MPT:

1. Ukusebenza okuphezulu:

Uma kuqhathaniswa nabalawuli be-PWM, abalawuli be-MPTT bangandisa ukusebenza kahle kwezinhlelo zelanga nge-30%, ikakhulukazi lapho i-solar panlel voltage iphakeme kune-voltage yebhethri.

2. Ukusebenza okungcono ezimeni eziphansi zokukhanya:

Isilawuli se-MPPT senza kahle ezimweni eziphansi zokukhanya, okwenza kube yinto elungele ukugqama okuphuzi kwelanga okudinga ukusebenza kahle ngisho nasezinsukwini ezingamafu noma kusihlwa.

3. Ukuguquguquka kwesistimu:

Abalawuli beMPTT bavumela ukuguquguquka okukhulu ekwakhiweni kwesistimu ukuze kusetshenziswe amaphaneli e-volara ephakeme, anganciphisa izindleko zokuzithambisa kanye nokulahleka.

Yisiphi isilawuli esingcono kakhulu ngokukhanya okuphuzi okuphuzi kwelanga?

Lapho ukhetha abalawuli be-MPPT kanye ne-PWM ngokukhanya okuphuzi kwelanga kwelanga, isinqumo sincike kakhulu kwizidingo ezithile zohlelo lwakho lokusebenza.

- Kwamaphrojekthi amancane, wesabelomali: Uma usebenza ngephrojekthi encane enesabelomali esilinganiselwe, isilawuli se-PWM singase sekwanele. Zithembekile, zibiza kakhulu, futhi zinganikeza amandla anele amalambu aphuzi aphuzi elanga ngaphansi kwezimo ezifanele.

- Izicelo ezinkulu noma eziningi ezifunwayo: Uma iphrojekthi yakho idinga ukusebenza kahle okukhulu, ikakhulukazi ngaphansi kokushintsha izimo zokukhanya, isilawuli se-MPPT yisinqumo esingcono. Ukwanda kokusebenza kahle kanye nokusebenza kwezimo eziphansi zokukhanya kwenza abalawuli be-MPT balungele ukuqinisekisa ukuthi amalambu akho avuthayo elanga ahlala esebenza ngokuthembekile.

Ekuphetheni

Njengomhlinzeki okhanyayo ophuzi okhanyayo ophuzi, i-qixiang izimisele ukuhlinzeka ngemikhiqizo esezingeni eliphakeme kanye nesiqondiso sochwepheshe ukukusiza wenze ukukhetha okuhle kwelanga. Noma ngabe ukhetha isilawuli se-PWM noma i-MPTT, ukuqonda umehluko kanye nezinzuzo zalowo nalowo kungasiza ekukhetheni isisombululo esifanele sohlelo lwakho olukhanyayo olukhanyayo olukhanyayo.

Kwesilinganiso esenziwe ngezifiso noma usizo olwengeziwe ekukhetheni okulungileukukhanya okuphuzi okukhanyayo nokulawulwaNgephrojekthi yakho, sicela ukhululeke ukuxhumana ne-qixiang. Silapha ukukunikeza izixazululo ezinokwethenjelwa zelanga ukukhanyisa indlela yakho!
