Yintoni i-solar conditioner?

I-conditioner yelanga iqinisekisa ukuba umbane owenziwe yipaneli yelanga udluliselwa ngengqondo kwibhetri ngendlela efanelekileyo kwikhemistri yebhetri kunye nenqanaba lentlawulo.Umlawuli olungileyo uya kuba ne-algorithm yokuhlawula izigaba ezininzi (ngokuqhelekileyo izigaba ezi-5 okanye ezi-6) kwaye zibonelele ngeenkqubo ezahlukeneyo zeentlobo ezahlukeneyo zeebhetri.Abalawuli banamhlanje, abakumgangatho ophezulu baya kubandakanya iinkqubo ezithile zeebhetri zeLithium, ngelixa iimodeli ezininzi ezindala okanye ezingabizi kakhulu ziya kulinganiselwa kwi-AGM, iGel kunye neebhetri eziManzi.Kubalulekile ukuba usebenzise inkqubo echanekileyo yohlobo lwebhetri yakho.

Ulawulo oluhle lwelanga luya kubandakanya inani leesekethe zokukhusela i-electronics ukukhusela ibhetri, kubandakanywa ukukhuselwa kwe-polarity reverse, ukukhuselwa kwesiphaluka esifutshane, ukukhuselwa kwangoku, ukukhuselwa kwe-overcharge, ukukhuselwa kwe-overvoltage okwethutyana, kunye nokukhuselwa kobushushu obungaphezulu.

Iindidi zeSolar Regulators

Kukho iintlobo ezimbini eziphambili zee-solar conditioners ezikhoyo kwiipaneli zelanga eziphathekayo.I-Pulse Width Modulation (PWM) kunye neMaximum Power Point Tracking (MPPT).Zonke zineengenelo zazo kunye nezingeloncedo, nto leyo ethetha ukuba nganye ifanelekile kwiimeko ezahlukeneyo zokukhempisha.

UkuModelwa koBububanzi bePulse (PWM)

I-Pulse Width Modulation (PWM), umlawuli unoqhagamshelo oluthe ngqo phakathi kwephaneli yelanga kunye nebhetri, kwaye usebenzisa "ukutshintsha ngokukhawuleza" indlela yokulawula ukutshaja okugeleza kwibhetri.Umtshini uhlala uvulekile ngokupheleleyo de ibhetri ifike kumbane we-sink, apho utshintshi luqala ukuvula nokuvala amaxesha angamakhulu ngomzuzwana ukunciphisa okwangoku ngelixa ugcina i-voltage rhoqo.

Kwithiyori, olu hlobo lonxibelelwano lunciphisa ukusebenza kwepaneli yelanga kuba amandla ombane ephaneli athotywa ukuze atshatise umbane webhetri.Nangona kunjalo, kwimeko yeephaneli zelanga eziphathwayo eziphathwayo, isiphumo esisebenzayo sincinci, njengoko kumaxesha amaninzi amandla ombane aphezulu ephaneli ajikeleze i-18V kuphela (kwaye ayancipha njengoko ipaneli ishushu), ngelixa amandla ombane ebhetri ahlala phakathi kwe-12-13V. (AGM) okanye i-13-14.5V (iLithium).

Ngaphandle kwelahleko encinci ekusebenzeni kakuhle, abalawuli be-PWM ngokuqhelekileyo babonwa njengokhetho olungcono lokubhanqa kunye neepaneli zelanga eziphathekayo.Izibonelelo zabalawuli be-PWM xa kuthelekiswa nabalingane babo be-MPPT banobunzima obuphantsi kunye nokuthembeka okukhulu, okuyizona ingqwalasela eziphambili xa ubeka iinkampu ixesha elongezelelweyo okanye kwiindawo ezikude apho inkonzo ingenakufikeleleka lula kwaye kunokuba nzima ukufumana i-Alternative regulator.

Eyona ndawo iphezulu yokuJonga iPower Point (MPPT)

Amandla aphezulu okulandelela iMPPT, umlawuli unamandla okuguqula i-voltage engaphezulu kwi-current eyongezelelweyo phantsi kweemeko ezifanelekileyo.

Umlawuli weMPPT uya kuhlala ebeka iliso kwi-voltage yepaneli, ehlala iguquka ngokusekelwe kwizinto ezifana nokushisa kwepaneli, iimeko zemozulu kunye nendawo yelanga.Isebenzisa amandla ombane apheleleyo ephaneli ukubala (ukulandelela) eyona ndibaniselwano yombane kunye neyangoku, emva koko inciphise amandla ombane ukuze ihambelane nombane wokutshaja webhetri ukuze ibonelele ngoku ongezelelweyo kwibhetri (khumbula amandla = i-voltage x yangoku) .

Kodwa kukho i-caveat ebalulekileyo enciphisa umphumo osebenzayo wabalawuli beMPPT kwiipaneli zelanga eziphathekayo.Ukufumana nayiphi na inzuzo yokwenene kumlawuli weMPPT, i-voltage kwiphaneli kufuneka ibe ubuncinane i-4-5 volts ephezulu kune-voltage yentlawulo yebhetri.Ngenxa yokuba ezininzi iipaneli zelanga eziphathwayo zine-voltage enkulu ejikeleze i-18-20V, enokuthi yehle kwi-15-17V xa ishushu, ngelixa iibhetri ezininzi ze-AGM ziphakathi kwe-12-13V kunye neebhetri ezininzi ze-lithium phakathi kwe-13-14.5V Ngeli xesha, Umahluko we-voltage awanelanga ukuba umsebenzi weMPPT ube nefuthe lokwenyani kumbane wokutshaja.

Xa kuthelekiswa nabalawuli be-PWM, abalawuli beMPPT banobugwenxa bokuba nzima ubunzima kwaye ngokuqhelekileyo bathembeke kakhulu.Ngesi sizathu, kunye nefuthe labo elincinci kwigalelo lamandla, awuzukuhlala uzibona zisetyenziswa kwiingxowa ezisongekayo zelanga.
