Iyini i-solar conditioner?

I-solar conditioner iqinisekisa ukuthi ugesi owenziwe iphaneli yelanga udluliselwa ngobuhlakani ebhethri ngendlela efanele ikhemistri yebhethri kanye nezinga lokushaja.Isilawuli esihle sizoba ne-algorithm yokushaja yezigaba eziningi (imvamisa izigaba ezi-5 noma eziyisi-6) futhi sinikeze izinhlelo ezihlukene zezinhlobo ezahlukene zamabhethri.Izilawuli zesimanje, zekhwalithi ephezulu zizofaka izinhlelo ezithile zamabhethri e-Lithium, kuyilapho amamodeli amaningi amadala noma ashibhile azokhawulelwa kumabhethri e-AGM, Gel kanye nama-Wet.Kubalulekile ukuthi usebenzise uhlelo olufanele lohlobo lwebhethri lakho.

Isilawuli selanga esihle sekhwalithi sizobandakanya inani lamasekhethi okuvikela ama-elekthronikhi ukuvikela ibhethri, okuhlanganisa ukuvikelwa kwe-polarity okuhlehlayo, ukuvikelwa kwesekethe emfushane, ukuvikela kwamanje okuhlehlayo, ukuvikela ukushajwa ngokweqile, ukuvikelwa kwe-overvoltage yesikhashana, nokuvikela izinga lokushisa elingaphezu kwamandla.

Izinhlobo zama-Solar Regulators

Kunezinhlobo ezimbili eziyinhloko zama-solar conditioners atholakalayo kumaphaneli elanga aphathwayo.I-Pulse Width Modulation (PWM) kanye ne-Maximum Power Point Tracking (MPPT).Wonke anezinzuzo zawo kanye nokubi, okusho ukuthi ngayinye ifanele izimo zokukhempa ezahlukene.

I-Pulse Width Modulation (PWM)

I-Pulse Width Modulation (PWM), isilawuli sinokuxhumana okuqondile phakathi kwephaneli yelanga nebhethri, futhi sisebenzisa indlela “yokushintsha ngokushesha” ukuze ilawule ukushajwa okugeleza kubhethri.Iswishi ihlala ivuleke ngokugcwele kuze kube yilapho ibhethri ifinyelela ku-voltage ka-sink, ngaleso sikhathi iswishi iqala ukuvula nokuvala izikhathi ezingamakhulu ngomzuzwana ukuze kuncishiswe amandla amanje ngenkathi igcina i-voltage ingashintshi.

Ngokombono, lolu hlobo lokuxhuma lunciphisa ukusebenza kwephaneli yelanga ngoba amandla ombane wephaneli ayehliswa ukuze afane nomthamo webhethri.Kodwa-ke, endabeni yamaphaneli elanga okukhempa aphathwayo, umphumela ongokoqobo mncane, njengoba ezimweni eziningi amandla kagesi aphezulu ephaneli acishe abe ngu-18V kuphela (futhi ayehla njengoba iphaneli ishisa), kuyilapho amandla kagesi ebhethri evamise ukuba phakathi kuka-12-13V. (AGM) noma 13-14.5V (Lithium).

Naphezu kokulahlekelwa okuncane ekusebenzeni kahle, abalawuli be-PWM ngokuvamile babhekwa njengenketho engcono yokumatanisa namaphaneli elanga aphathwayo.Izinzuzo zabalawuli be-PWM uma kuqhathaniswa nozakwabo be-MPPT zinesisindo esiphansi nokwethembeka okukhulu, okuyizinto ezibalulekile zokucatshangelwa lapho ukhempa isikhathi eside noma ezindaweni ezikude lapho isevisi ingase ingafinyeleleki kalula futhi kungase kube nzima ukuthola esinye isilawuli.

I-Maximum Power Point Tracking (MPPT)

I-MPPT yokulandela indawo yamandla amaningi, isilawuli sinamandla okuguqula i-voltage eyeqile ibe yamanje eyengeziwe ngaphansi kwezimo ezifanele.

Isilawuli se-MPPT sizohlala siqapha amandla kagesi ephaneli, ehlala ishintsha ngokusekelwe ezicini ezifana nokushisa kwephaneli, izimo zezulu kanye nokuma kwelanga.Isebenzisa i-voltage egcwele yephaneli ukubala (ilandelela) inhlanganisela engcono kakhulu yamandla kagesi neyamanje, bese inciphisa i-voltage ukuze ihambisane nomthamo wokushaja webhethri ukuze inikeze amandla angeziwe ebhethri (khumbula amandla = i-voltage x yamanje) .

Kodwa kukhona i-caveat ebalulekile enciphisa umphumela osebenzayo wezilawuli ze-MPPT zamaphaneli elanga aphathwayo.Ukuze uthole noma iyiphi inzuzo yangempela kusilawuli se-MPPT, i-voltage kuphaneli kufanele okungenani ibe ngama-volts angu-4-5 ngaphezu kwamandla kagesi ebhethri.Njengoba kunikezwe ukuthi amaphaneli elanga amaningi aphathwayo ane-voltage enkulu ezungeze i-18-20V, engehla iye ku-15-17V lapho eshisa, kuyilapho amabhethri amaningi e-AGM ephakathi kuka-12-13V namabhethri amaningi e-lithium phakathi kuka-13-14.5V Ngalesi sikhathi, umehluko we-voltage awanele ukuze umsebenzi we-MPPT ube nomthelela wangempela kumanje wokushaja.

Uma kuqhathaniswa nezilawuli ze-PWM, abalawuli be-MPPT banenkinga yokuba nesisindo esikhudlwana futhi ngokuvamile abathembeki kangako.Ngalesi sizathu, kanye nomthelela wawo omncane ekufakweni kwamandla, ngeke uvame ukuzibona zisetshenziswa ezikhwameni ezigoqekayo zelanga.
