Ukuvula ngokuSebenzayo: Njani iMPPT abalawuli beCharge yeSolar baVuselela amandla aVuselelwayo

Kwihlabathi lamandla ahlaziyekayo, akukho nto ihlala ilungile ngokwaneleyo. Phambi kolu mfuno luqhubekayo lokuphucula ukusebenza kakuhle kunye nokuthembeka rhoqo, sinokuqiniseka ukuba itekhnoloji enye iya kubona izinto ezininzi. Kum, umlawuli wentlawulo yelanga yeMPPT nguyena. Eli nqaku liza kucazulula eyona nto ingundoqo ye-MPPT yokulawula intlawulo yelanga. Uya kufunda ukuba zeziphi ezi zixhobo, zisebenza njani, kutheni kufuneka uzisebenzise, ​​yintoni ekufuneka uyiqwalasele ngaphambi kokuba uzifake, ungenza ntoni ukuze uqinisekise ukuba ziyahambelana nenkqubo yakho, kunye nokunye. Ekupheleni kweli nqaku, kufuneka ube nokuqonda okuhambelanayo malunga nendlela onokwenza ngayo uninzi lwezi zixhobo ngokuzibandakanya kwinkqubo yakho yamandla elanga.

Isiqulatho:
– Ukuqonda iteknoloji yolawulo lwelanga yeMPPT
-Iinzuzo eziphambili zokusebenzisa isilawuli sentlawulo yelanga seMPPT

Abalawuli be-MPPT yiteknoloji ehamba phambili ekuguquleni amandla elanga - bacinezela amandla amaninzi ngaphandle kweepaneli. Ngokungafaniyo nabalawuli be-PWM, umlawuli weMPPT uya kulungelelanisa ngokuzenzekelayo igalelo lombane ngokusekelwe koko iipaneli zelanga ezikwaziyo ukuhambisa ngelo xesha kunye neemeko ze-ambient. Unokuthi abalawuli beMPPT bavuna 'indawo eswiti' yamandla eepaneli. Ikwenza oku isebenzisa ii-algorithms ukuba lonke ixesha ilandelela ukuba yintoni eyona ndawo yolawulo lwephaneli (MPP) eneneni, kwaye emva koko ihlengahlengise umbane ukuya kwelo nqanaba kwaye iyibambe apho ngokungenasiphelo.

Ubuncinci yiloo nto isilawuli seMPPT ngokusisiseko - umlamli okrelekrele phakathi koluhlu lwelanga kunye nebhanki yebhetri yenkqubo yamandla avuselelekayo. Ngokuguqula i-overvoltage engafunekiyo kwi-amperage esebenzisekayo, umlawuli weMPPT unokunyusa ukutshaja kwebhanki yebhetri ngeepesenti ze-20 okanye ngaphezulu. Ikwanceda ekucutheni ixesha lokuhlawulisa, ukunciphisa umthamo welanga ochithwayo. Kwangokunjalo, umlawuli weMPPT wandisa ubomi bebhanki ngokunciphisa ukutshajiswa kweebhetri.

Njengoko i-evolution yeteknoloji ye-MPPT ibonisa, nangona kunjalo, isizukulwana esilumkileyo, esiphendulayo seenkqubo zamandla avuselelekayo ezidibeneyo zisondele. Njengoko sisenza iiphaneli zelanga ezingcono kunye neebhetri, indima yalo mlawuli ekuxolelaniseni zombini ibaluleke kakhulu kunangaphambili. Umlawuli ngamnye weMPPT, emva kwayo yonke loo nto, yinxalenye ebalulekileyo yokuzisa amandla elanga angaphezulu emhlabeni.

Olona ncedo lukhawulezayo lweMPPT abalawuli belanga bentlawulo yelanga kukuba benza iinkqubo zethu zamandla elanga zisebenze ngcono. Ngenxa yokonyuka kokutshaja okusebenzayo, kukho inkcitho encinci yamandla, elingana namaxesha akhawulezayo okutshaja kunye nezivuno eziphezulu zamandla. Oku kuluncedo ngokukodwa kwiindawo ezinokukhanya okulinganiselweyo kwelanga, apho ukubamba yonke imitha yelanga kubalulekile.

Ukongezelela, abalawuli beMPPT banceda ukuqinisekisa ukuba ixesha elide lenkqubo libonga amandla abo okugcina iibhetri ngaphakathi kwefestile yabo yokutshaja ngokufanelekileyo ngokuthintela ngokufanelekileyo ukugqithiswa kunye nokukhutshwa okunzulu. Isiphumo asikho kuphela iibhetri ezihlala ixesha elide, kodwa inkqubo yokugcina ethembekileyo ngexesha elibalulekileyo kuyo nayiphi na inkqubo ye-off-grid.

Enye yeenzuzo ezongezelelweyo zeteknoloji ye-MPPT kukuba aba balawuli banokusebenza kuluhlu olukhulu kakhulu lwee-voltages zegalelo, oku kuthetha ukuba zingasetyenziswa phantse naluphi na uhlobo lwe-PV, ezenza ukuba zisebenziseke kakhulu kulwandiso lwexesha elizayo okanye ukuphuculwa kwenkqubo ngaphandle kokutshintsha umlawuli wentlawulo.

Ukulinganisa ngokufanelekileyo i-MPPT yesilawuli sentlawulo yelanga kulula, kodwa ukuthatha ixesha lokuyenza ngendlela efanelekileyo kuya kuqinisekisa ukuba umlawuli uya kukunika ubuninzi bamandla asebenzisekayo kwiiphaneli zakho. Qala ngokulinganisa iMPPT yolawulo lwentlawulo ngokwayo. I-ampacity yomlawuli kufuneka ubuncinane ilingane nesiphumo esiphezulu soluhlu lwakho lwelanga kunye nenani eliphezulu (i-100 pesenti) yentlawulo yeebhetri zakho. Uluhlu ngalunye lwelanga luza nomlinganiselo wamandla, okuxelela ukuba zingaphi iiwathi zamandla eziya kuvelisa phantsi kweemeko ezifanelekileyo. Umzekelo, uluhlu lwethu lwelanga lwe-480W luya kuvelisa malunga ne-600W yamandla emini yelanga phantsi kweemeko ezifanelekileyo.

Iingcingo ezilungileyo ziyimfuneko. Ucingo olusetyenzisiweyo malube yigeyiji ecetyiswayo kwikhithi yomyalelo kwaye uqhagamshelo kufuneka luqine kwaye lungaqhawuki. Oku kuya kunciphisa ukuhla kwamandla ombane kwaye kwandise ukusebenza kakuhle. Isilawuli ngokufanelekileyo kufuneka sifakwe kwindawo engavezwanga kubushushu obugqithisileyo njengoko oku kuya kwandisa ixesha elide kunye nokusebenza kakuhle.

Ekugqibeleni, umlawuli kufuneka amiselwe inkqubo yakho ethile. Phantse bonke abalawuli beMPPT banenani lezicwangciso ezinokuthi zitshintshwe ukuze zihambelane neempawu zeepaneli zelanga kunye neebhetri. Ukufumana ezi zinto zilungile kufuna imizuzu embalwa yovavanyo, kodwa kungenza umahluko omkhulu ekusebenzeni kwenkqubo.

Xa umlawuli welanga weMPPT eyinxalenye yesixokelelwano sakho samandla elanga, kufuneka uqiniseke ukuba asihambelani kuphela noluhlu lwephaneli yakho yelanga kodwa kunye namanye amacandelo. Kwicala lepaneli yelanga, i-voltage ye-array kufuneka ihambelane neenkcukacha zomlawuli ukuze umlawuli akhuphe onke amandla anokubakho. Ngokubhekiselele kwicala lebhetri, umlawuli kufuneka ahambelane nohlobo lweebhetri, ezifana ne-lead-acid, i-lithium-ion okanye ezinye iteknoloji.

Umba wokugqibela ngumthamo womlawuli. Kubalulekile ukufakela isilawuli esikwaziyo ukuphatha inkqubo njengoko injalo ngoku, kwaye uqikelele ukuba ingaba yintoni na. Ukulayisha ngaphezulu komlawuli kunokubangela inkqubo engafanelekanga ukuba isetyenziswe.

Okokugqibela kodwa kuncinci, kufuneka isebenze kakuhle kunye namanye amacandelo enkqubo, kubandakanywa ii-inverters kunye nabahloli, kuba oko kudityaniswa yinto eyenza inkqubo isebenze kakuhle nangempumelelo.

Umlawuli wentlawulo yelanga yeMPPT sisixhobo sokugcinwa phantsi kweemeko eziqhelekileyo. Kodwa ukwenza uhlolisiso ngamaxesha athile kunokuthintela umonakalo. Ungajonga rhoqo iitheminali zayo kunye noqhagamshelo lweengcingo kuzo naziphi na iimpawu zokunxiba kunye nokukrazula. Okona kubaluleke kakhulu, kufuneka ugcine itshaja icocekile eluthulini nakwenye inkunkuma ngelixa uqinisekisa ukulahlwa kobushushu.

Kwiingxaki eziqhelekileyo ezifana nokunciphisa ukusebenza kakuhle okanye ukusilela ukuhlawulisa, izisombululo zihlala zilele ekujongeni useto lokucoca okanye uqhagamshelo. Ukuhlaziya i-firmware kunokusombulula iibugs zesoftware, enokuphucula ukusebenza komlawuli kunye nokuhambelana neebhetri ezintsha okanye iiphaneli.

Ukuqukumbela, abalawuli be-MPPT bentlawulo yelanga bayitekhnoloji ephambili yokufumana amandla aphezulu kunye nokunciphisa ilahleko ngelixa usebenzisa amandla elanga. Siyathemba ukuba ngoku unokuqonda ngcono ukuba yintoni aba balawuli kwaye unokubasebenzisa ukwandisa amandla akho okuzimela usebenzisa umthombo wamandla ohlaziyekayo kwikamva lakho.
