Ngohlelo oluxhunywe kugridi yelanga, isikhathi nesimo sezulu kuzodala izinguquko emisebeni yelanga, futhi i-voltage endaweni yamandla izoshintsha njalo. Ukuze ukwandise inani likagesi okhiqizwayo, kuqinisekiswa ukuthi ama-solar panels angalethwa ngokukhipha okuphezulu kakhulu lapho ilanga libuthakathaka futhi linamandla. Amandla, ngokuvamile i-boost boost system yengezwa ku-inverter ukuze kwandiswe i-voltage endaweni yayo yokusebenza.
Uchungechunge oluncane olulandelayo luchaza ukuthi kungani kufanele usebenzise i-boost boost, nokuthi isistimu ye-boost boost ingasiza kanjani isistimu yamandla elanga ukukhulisa ukukhiqizwa kwamandla.
Kungani Uthuthukisa Isekethe?
Okokuqala, ake sibheke uhlelo oluvamile lwe-inverter emakethe. Iqukethe i-boost boost circuit kanye ne-inverter circuit. Indawo ephakathi ixhunywe ngebhasi le-DC.
Isifunda se-inverter sidinga ukusebenza kahle. Ibhasi le-DC kufanele libe phezulu kunesiqongo se-voltage yegridi (uhlelo lwezigaba ezintathu lungaphezu kwenani eliphakeme le-voltage yomugqa), ukuze amandla akwazi ukuphuma kugridi ukuya phambili. Ngokujwayelekile ukuze kusebenze kahle, ibhasi le-DC livamise ukushintsha nge-voltage yegridi. , ukuze kuqinisekiswe ukuthi iphakeme kunegridi yamandla.
Uma i-voltage yephaneli iphakeme kune-voltage edingekayo ye-busbar, i-inverter izosebenza ngokuqondile, futhi i-voltage ye-MPPT izoqhubeka ilandelela endaweni ephezulu. Kodwa-ke, ngemva kokufinyelela imfuneko ye-voltage yebhasi encane, ayikwazi ukuncishiswa futhi, futhi iphuzu eliphezulu lokusebenza kahle alikwazi ukutholakala. Ububanzi be-MPPT buphansi kakhulu, okunciphisa kakhulu ukusebenza kahle kokukhiqizwa kwamandla futhi inzuzo yomsebenzisi ayinakuqinisekiswa. Ngakho-ke kufanele kube nendlela yokulungisa lokhu kushiyeka, futhi onjiniyela basebenzisa ama-Boost boost circuits ukufeza lokhu.
I-Boost Boost kanjani ububanzi be-MPPT ukukhulisa ukukhiqizwa kwamandla?
Lapho i-voltage yephaneli iphakeme kune-voltage edingekayo yi-busbar, isifunda se-booster booster sisesimweni sokuphumula, amandla alethwa ku-inverter ngokusebenzisa i-diode yayo, futhi i-inverter iqedela ukulandelela kwe-MPPT. Ngemva kokufinyelela i-voltage edingekayo ye-busbar, i-inverter ayikwazi ukuthatha. IMPPT isebenzile. Ngalesi sikhathi, ingxenye ye-boost boost ithathe ukulawula i-MPPT, yalandelela i-MPPT, futhi yaphakamisa ibha yebhasi ukuze kuqinisekiswe ugesi wayo.
Ngobubanzi obubanzi bokulandelela kwe-MPPT, uhlelo lwe-inverter lungadlala indima ebalulekile ekwandiseni i-voltage yamapaneli elanga ekuseni, isigamu sobusuku, nezinsuku zemvula. Njengoba singabona esithombeni esingezansi, amandla esikhathi sangempela ayabonakala. Nyusa.
Kungani isiguquli samandla esikhulu sivame ukusebenzisa amasekhethi amaningi e-Boost boost ukwandisa inani lamasekhethi e-MPPT?
Isibonelo, uhlelo lwe-6kw, ngokulandelana kwe-3kw kuya ophahleni olubili, ama-inverters amabili we-MPPT kufanele akhethwe ngalesi sikhathi, ngoba kunezindawo ezimbili ezizimele eziphezulu zokusebenza, ilanga lasekuseni liphuma empumalanga, ukuchayeka okuqondile ku-A surface Kuphaneli yelanga. , i-voltage namandla ohlangothini lwe-A kuphezulu, futhi uhlangothi lwe-B luphansi kakhulu, futhi ntambama luphambene. Uma kunomehluko phakathi kwama-voltage amabili, i-voltage ephansi kufanele ikhuliswe ukuze ilethe amandla ebhasini futhi kuqinisekiswe ukuthi isebenza endaweni ephezulu yamandla.
Isizathu esifanayo, indawo enamagquma endaweni eyinkimbinkimbi kakhulu, ilanga lizodinga ukukhanya okwengeziwe, ngakho-ke lidinga i-MPPT ezimele, ngakho-ke amandla aphakathi nendawo aphezulu, njengama-inverters angu-50Kw-80kw ngokuvamile angu-3-4 ozimele we-Boost, ngokuvamile athi. 3-4 MPPT ezimele.
