Amaphaneli elanga aphathwayo awenza kanjani ngempela ugesi?

Amaphaneli elanga aphathwayo asebenza ngokubamba ukukhanya kwelanga futhi akuguqule kube ugesi owusizo ngocingo olubizwa ngokuthi isilawuli sokushaja noma isilawuli.Isilawuli sibe sesixhunywa ebhethrini, igcine ishajiwe.

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.
