I-MPPT vs. PWM: Ngowuphi umlawuli ofanelekileyo kwisibane esikhanyayo esityheli selanga?

Kwicandelo lezisombululo zelanga,izibane ezikhanyayo zelanga ezityheliziye zaba yinxalenye ebalulekileyo yezicelo ezahlukeneyo kuquka ulawulo lwezithuthi, iindawo zokwakha, kunye nemiqondiso yongxamiseko. Njengomthengisi onamava wezibane ezikhanyayo zelanga ezimthubi, uQixiang uyayiqonda into ebalulekileyo yokukhetha isilawuli esifanelekileyo ukuze kuphuculwe ukusebenza kwezi zibane. Kukho iintlobo ezimbini eziphambili zezixhobo zokulawula itshaja yelanga ezisetyenziswa rhoqo kwizicelo zelanga: Ukulandelela iMaximum Power Point (MPPT) kunye nePulse Width Modulation (PWM). Eli nqaku liza kujonga umahluko phakathi kwezixhobo zokulawula zeMPPT kunye nePWM kwaye likuncede ukhethe ukuba yeyiphi isilawuli esifanelekileyo kwiimfuno zakho zokukhanya okukhanyayo kwelanga okumthubi.

Funda ngezilawuli zokutshaja zelanga

Ngaphambi kokuba ujonge uthelekiso, kubalulekile ukuqonda into eyenziwa yi-solar charge controller. Ezi zixhobo zilawula i-voltage kunye nomsinga ukusuka kwiipaneli zelanga ukuya kwibhetri, ziqinisekisa ukuba ibhetri itshajwa ngokufanelekileyo nangokukhuselekileyo. Ukukhethwa kwe-controller kunokuchaphazela kakhulu ukusebenza kunye nobude benkqubo yakho yokukhanya okutyheli kwelanga.

Abalawuli bePWM

Abalawuli be-pulse width modulation (PWM) lolona hlobo lwesiqhelo lwe-solar charge controller. Basebenza ngokudibanisa i-solar panel ngqo kwibhetri nokusebenzisa uthotho lwe-switching signals ukulawula inkqubo yokutshaja. Ububanzi be-“on” signal buyahlengahlengiswa ngokusekelwe kwimeko yebhetri yokutshaja, okuvumela inkqubo yokutshaja ezinzileyo nelawulekayo.

Iingenelo ze-PWM Controllers:

1. Kulula kwaye kuyabiza:

Izilawuli zePWM ngokubanzi zibiza kancinci kwaye kulula ukuzifaka kunezilawuli zeMPPT. Oku kuzenza zibe lukhetho olunomtsalane kwiiprojekthi ezijongana nebhajethi.

2. Ukuthembeka:

Ngenxa yokuba zimbalwa izinto kunye noyilo olulula, abalawuli be-PWM badla ngokuba nokuthembeka ngakumbi kwaye abafuni ukugcinwa okuninzi.

3. Ukusebenza kakuhle kwiiNkqubo ezincinci:

Kwiinkqubo zelanga ezincinci apho i-voltage yephaneli yelanga ifana kakhulu ne-voltage yebhetri, ukusebenza kakuhle kwesilawuli se-PWM kuphezulu kakhulu.

Abalawuli be-MPPT

Abalawuli beMaximum Power Point Tracking (MPPT) bubuchwepheshe obuphucukileyo obuphucula amandla afunyenwe kwiiphaneli zelanga. Bahlala bejonga imveliso yeephaneli zelanga kwaye balungisa indawo yokusebenza yombane ukuqinisekisa ukuba kukhutshwa amandla aphezulu.

Iingenelo zoMlawuli we-MPPT:

1. Ukusebenza kakuhle okuphezulu:

Xa kuthelekiswa nabalawuli bePWM, abalawuli beMPPT banokunyusa ukusebenza kakuhle kweenkqubo zelanga ukuya kuthi ga kwi-30%, ingakumbi xa i-voltage yephaneli yelanga iphezulu kune-voltage yebhetri.

2. Ukusebenza ngcono kwiimeko zokukhanya okuphantsi:

Isilawuli seMPPT sisebenza kakuhle kwiimeko zokukhanya okuphantsi, nto leyo eyenza ukuba silungele ukukhanya okutyheli kwelanga okufuneka kusebenze ngokufanelekileyo nokuba kusezinzulwini okanye xa kutshona ilanga.

3. Ukuguquguquka koyilo lwenkqubo:

Abalawuli be-MPPT bavumela ukuguquguquka okukhulu kuyilo lwenkqubo ukusebenzisa iiphaneli zelanga ezine-voltage ephezulu, nto leyo enokunciphisa iindleko zocingo kunye nelahleko.

Ngowuphi umlawuli ofanelekileyo kwi-solar yellow light flash?

Xa ukhetha izilawuli ze-MPPT kunye ne-PWM zokukhanya okutyheli kwelanga, isigqibo sixhomekeke kakhulu kwiimfuno ezithile zesicelo sakho.

- Kwiiprojekthi ezincinci, ezinqongopheleyo kwibhajethi: Ukuba usebenza kwiprojekthi encinci enebhajethi encinci, isilawuli se-PWM sinokwanela. Zithembekile, zingabizi kakhulu, kwaye zinokubonelela ngamandla aneleyo kwizibane ezikhanyayo ezimthubi zelanga phantsi kweemeko ezifanelekileyo.

- Kwiizicelo ezinkulu okanye ezifuna amandla amaninzi: Ukuba iprojekthi yakho ifuna ukusebenza kakuhle, ingakumbi phantsi kweemeko zokukhanya ezitshintshayo, isilawuli seMPPT silona khetho lungcono. Ukusebenza kakuhle kunye nokusebenza kakuhle kwiimeko zokukhanya okuphantsi kwenza abalawuli beMPPT bafaneleke ukuqinisekisa ukuba izibane zakho ezikhanyayo zelanga ezimthubi zihlala zisebenza ngokuthembekileyo.
