Emhlabeni wamandla avuselelekayo, akukho lutho oluhle ngokwanele. Uma sibhekene nalesi sifiso esiqhubekayo sokusebenza okuthuthukayo njalo nokwethembeka njalo, singaqiniseka ukuthi ubuchwepheshe obubodwa buzobona izenzo eziningi. Kimina, isilawuli se-MPPT solar charge yisona. Lesi sihloko sizohlukanisa ingqikithi yezilawuli zokushaja zelanga ze-MPPT. Uzofunda ukuthi ayini la madivayisi, asebenza kanjani, kungani kufanele uwasebenzise, yini okudingeka uyicabangele ngaphambi kokuwafaka, yini ongayenza ukuze uqiniseke ukuthi ahambisana nesistimu yakho, nokunye. Ekupheleni kwalesi sihloko, kufanele ube nokuqonda okuhambisanayo kokuthi ungenza kanjani okuningi kulawa madivayisi ngokuwahlanganisa ohlelweni lwakho lwamandla elanga.
Okuqukethwe:
- Ukuqonda ubuchwepheshe besilawuli se-MPPT solar charge
- Izinzuzo ezibalulekile zokusebenzisa isilawuli se-solar se-MPPT
- Amathiphu okufaka izilawuli zokushaja zelanga ze-MPPT

Ukuqonda ubuchwepheshe be-MPPT solar charge controller technology
Izilawuli ze-MPPT zihamba phambili kwezobuchwepheshe ekuguquleni amandla elanga - zikhama amandla amaningi ngaphandle kwamaphaneli. Ngokungafani nezilawuli ze-PWM, isilawuli se-MPPT sizolungisa ngokuzenzakalelayo i-voltage yokufaka ngokusekelwe kulokho amaphaneli elanga akwazi ukukuletha ngaleso sikhathi kanye nezimo ze-ambient. Ungasho ukuthi abalawuli be-MPPT bavuna 'indawo emnandi' yamandla wamaphaneli'. Ikwenza lokhu isebenzisa ama-algorithms okuthi ngaso sonke isikhathi ilandelele ukuthi ingakanani iphuzu lamandla ephaneli (MPP), bese ilungisa i-voltage kulelo phuzu futhi iyibambe lapho unomphela.
Okungenani yilokho isilawuli se-MPPT esiyikho ngempela - umlamuli ohlakaniphile phakathi kohlu lwelanga nebhange lebhethri lesistimu yamandla avuselelekayo. Ngokuguqula ugesi omningi ongafuneki ube yi-amperage esebenzisekayo, isilawuli se-MPPT singakhuphula ukusebenza kahle kokushaja kwebhange lebhethri ngamaphesenti angama-20 noma ngaphezulu. Kuyasiza futhi ukunciphisa isikhathi sokushaja, ukunciphisa inani lokukhanya kwelanga elimoshayo. Ngendlela efanayo, isilawuli se-MPPT sinweba impilo yebhange lebhethri ngokukhawulela ukushajwa ngokweqile kwamabhethri.
Njengoba ukuvela kobuchwepheshe be-MPPT kukhombisa, nokho, isizukulwane esihlakaniphile, esisabelayo sezinhlelo zamandla avuselelekayo axhumene siseduze. Njengoba senza amaphaneli elanga namabhethri angcono, indima yalesi silawuli ekubuyisaneni kokubili ibaluleka kakhulu kunangaphambili. Isilawuli ngasinye se-MPPT, ngemuva kwakho konke, siyingxenye ebalulekile yokuletha amandla elanga amaningi emhlabeni.
Izinzuzo ezibalulekile zokusebenzisa isilawuli sokushaja solar seMPPT
Inzuzo esheshayo yezilawuli zokushaja zelanga ze-MPPT ukuthi zenza izinhlelo zethu zamandla elanga zisebenze kangcono. Ngenxa yokwanda kokushaja kahle, kunokumoshwa kwamandla amancane, okulingana nezikhathi zokushaja ezisheshayo kanye nesivuno esikhulu samandla. Lokhu kuwusizo ikakhulukazi ezindaweni ezinokuchayeka kancane elangeni, lapho ukuthatha yonke imisebe yelanga kubalulekile.
Ukwengeza, izilawuli ze-MPPT zisiza ukuqinisekisa impilo ende yesistimu ngenxa yekhono lazo lokulondoloza amabhethri ngaphakathi kwewindi lokushaja elifaneleka kakhulu ngokuvimbela ngempumelelo ukushajwa nokukhipha okujulile. Umphumela awuwona nje kuphela amabhethri ahlala isikhathi eside, kodwa uhlelo lokugcina oluthembekile ngokuhamba kwesikhathi olubalulekile kunoma iyiphi isistimu engaphandle kwegridi.
Enye yezinzuzo ezengeziwe zobuchwepheshe be-MPPT ukuthi lezi zilawuli zingasebenzisa uhla olukhulu kakhulu lwama-voltage okokufaka, okusho ukuthi zingasetshenziswa cishe nanoma yiluphi uhlobo lwe-PV, okuzenza zibe nezinto ezihlukahlukene kakhulu ukuze kwandiswe esikhathini esizayo noma kuthuthukiswe uhlelo ngaphandle kokushintsha isilawuli sokushaja.
Amathiphu okufaka izilawuli zokushaja zelanga ze-MPPT
Ukulinganisa kahle isilawuli sokushaja selanga se-MPPT kulula, kodwa ukuthatha isikhathi sokukwenza ngendlela efanele kuzoqinisekisa ukuthi isilawuli sizokunikeza inani eliphezulu lamandla asebenzisekayo avela kumaphaneli akho. Qala ngokulinganisa isilawuli sokushaja se-MPPT ngokwaso. I-ampacity yesilawuli kufanele okungenani ilingane nomkhawulo ophumayo we-solar yakho kanye nezinga lokushaja eliphezulu (amaphesenti angu-100) lamabhethri akho. Uhlu ngalunye lwelanga luza nesilinganiso samandla, esikutshela ukuthi mangaki ama-watts amandla azowakhiqiza ngaphansi kwezimo ezifanele. Isibonelo, i-solar yethu engu-480W izokhiqiza amandla acishe abe ngu-600W emini yelanga ngaphansi kwezimo ezifanele.
I-wiring enhle iyadingeka. Intambo esetshenzisiwe kufanele ibe yigeji enconywayo ekhithi yeziqondiso futhi ukuxhumana kufanele kuqine futhi kunganqamuki. Lokhu kuzonciphisa ukwehla kwamandla kagesi futhi kukhuphule ukusebenza kahle. Isilawuli kufanele sifakwe endaweni engachayeki kuma-elementi noma ekushiseni okudlulele njengoba lokhu kuzokwandisa impilo ende nokusebenza kahle nakho.
Okokugcina, isilawuli kufanele sisethelwe isistimu yakho ethile. Cishe zonke izilawuli ze-MPPT zinenani lezilungiselelo ezingalungiswa ukuze zifane nezici zamaphaneli elanga namabhethri. Ukulungisa lokhu kudinga imizuzu embalwa yokuhlola, kodwa kungenza umehluko omkhulu ekusebenzeni kwesistimu.
Ukucatshangelwa kokuhambisana kwesistimu yakho
Uma isilawuli sokushaja solar se-MPPT siyingxenye yesistimu yakho yamandla elanga, kufanele uqiniseke ukuthi asihambisani kuphela nephaneli yakho yelanga kodwa nezinye izingxenye. Ohlangothini lwephaneli yelanga, i-voltage ye-array kufanele ihambisane nokucaciswa kwesilawuli ukuze isilawuli sikwazi ukukhipha wonke amandla angaba khona. Ngokohlangothi lwebhethri, isilawuli kufanele sihambisane nohlobo lwamabhethri, njenge-lead-acid, i-lithium-ion noma obunye ubuchwepheshe.
Inkinga yokugcina umthamo wesilawuli. Kubalulekile ukufaka isilawuli esikwazi ukuphatha isistimu njengoba injalo manje, futhi ulindele ukuthi ingaba yini. Ukulayisha ngokweqile isilawuli kungaholela kusistimu okungafanelekile ukuyisebenzisa.
Okokugcina, kufanele kusebenze kahle nezinye izingxenye zesistimu, kufaka phakathi ama-inverters nama-monitor, ngoba lokho kuhlanganiswa yilokho okwenza uhlelo lusebenze kahle nangempumelelo.
Isondlo kanye nokuxazulula izinkinga
Isilawuli sokushaja solar se-MPPT siyidivayisi enakekela kancane ngaphansi kwezimo ezijwayelekile. Kodwa ukwenza ukuhlola ngezikhathi ezithile kungagwema umonakalo. Ungahlola njalo amatheminali ayo kanye noxhumo lwezintambo ukuze uthole noma yiziphi izimpawu zokugqokwa nokuklebhuka. Okubaluleke kakhulu, kufanele ugcine ishaja ihlanzekile othulini nakwenye imfucumfucu ngenkathi uqinisekisa ukushabalala kwezinga lokushisa elifanele.
Ezinkingeni ezivamile ezifana nokuncipha kokusebenza kahle noma ukwehluleka ukushaja, izixazululo ngokuvamile zilele ekuhloleni izilungiselelo zokuhlunga noma ukuxhumeka. Ukubuyekeza i-firmware kungase kuxazulule iziphazamisi zesofthiwe, okungase kuthuthukise ukusebenza kwesilawuli nokuhambisana namabhethri amasha noma amaphaneli.
Ekuphetheni, izilawuli zokushaja zelanga ze-MPPT ziwubuchwepheshe obuyinhloko bokuthola amandla amaningi kanye nokunciphisa ukulahlekelwa ngenkathi usebenzisa amandla elanga. Sithemba ukuthi manje usunokuqonda kangcono ukuthi lezi zilawuli ziyini futhi ungazisebenzisa ukukhulisa amandla akho okuzimela usebenzisa umthombo wamandla ovuselelekayo wekusasa lakho.
