Amaphonti Okuphakamisa Okwesibonelo Sokukhokha Kwemithombo Yomoya Wokuphakama

Ukukhetha ikhontrola yokufaka amandla we-MPPT eyodwa kuyisisekelo sokuphatha iprojekthi yakho yesolwe. Into eyokuqala ofanele ukuzifunda kukhetha yini umkhawulo wamandla ofanele. Kufanele uziqonde ukuthi umkhawulo wamandla wazo zonke izincwadi zasolwe wuyini. Isibonelo, uma izincwadi zasolwe zihlanganisa amawati angu-600, khetha ikhontrola eyakwamukela ngaphezu kwalokho. Kuyisisekelo sokhetha eyodwa enemiphumela eyengeziwe, ukuze isebenze ngendlela efanele nakuma kufakwe izincwadi eziningi emva kwalokho. Ungakhumbula futhi Amasistimu Ekuhambeni Kwesibanki Yomkhumbulo Wasekhaya Konke-Konke Ne-ESS Nge-Solar Charger Kusukela Ku-8kWh Ukuze Ku-20kWh njengesilungiso esinguqukile sokufuna umkhawulo wamandla.

Amaphonti we-charge we-MPPT ayizinkambo ezinhle kakhulu ukwenza ukuthi izindaba zokusebenza kwe-solar power zibe yisifiso. Kodwa ngamanye amaxesha azinamaphroblemi okungakwazi ukusebenza kahle. Indlela eyodwa yokubonakala yokuqondisa okungafanelekile. Uma izihluzi aziphindeke kahle, umphonti ungakhulise amabhatteri noma uhlule amabhatteri. Sicela uvumelane nokuphinda kahle kwezihluzi futhi uqinisekise ukuthi kufanele kuhambisana nezinsiza zika-Minvon ye-MPPT charge controller. Indlela eyodwa ibonakala uma izipaneli zokusebenza kwe-solar zibhacile noma zilichithwe. Amadusti, amaphakathi, noma isnow ingabulawa isibonelo sesibhakabhaka futhi isibophelela imiphumela yezipaneli ekusungulweni kwazo. Lokhu kusho ukuthi kunezimali ezingaphezu kwezimali ozikhipha umphonti ukuthi abe amabhatteri. Ngakho ke sicela ubheke izipaneli kahle futhi ubheke ukuthi akukho lutho olubulawa. Ngamanye amaxesha, amabhatteri kuphela kuyinto. Uma amabhatteri ayidala noma ayisebenzi kahle, kungalikhulise kahle. Lokhu kusho ukuthi umphonti we-MPPT awusebenzi kahle, kodwa kuyinto amabhatteri okufuneka kubuyiselwe. Kufanele ubheke amabhatteri ngokuphathelene nesikhathi futhi ubuyisеле uma kufuneka. Okokugcina, uma umphonti awavumelekile kahle, kungabangela iziproblemi. Yonke inqubo iyincazelo yokuvumela kubonakala ngokulinganayo kwezinhlobo zamabhatteri. Uma izinqubo zingafanele, kungabangela ukuthi amabhatteri zikhulise kakhulu noma zikhulise kancane. Sicela uvumelane nendlela yokusebenza ka-Minvon ukuthi uzivumele kahle ukusebenza.

I-MPPT ne-PWM yizinhlobo ezimbili zezinkontrola zokufaka amandla, futhi zisebenza ngendlela eyahlukene. I-MPPT ibonakala ukuthi yisibonelo sokulandela isiphumo esiphezulu kakhulu, futhi ngokuvamile iyasebenza ngokuphelele kune-PWM, okusho ukuthi yisibonelo sokulandela ubude bokuphakama kwemithambo. Isahluko esikhulu kukuthi zisebenza njani ngokubusa amandla emaphaneli wokuphakama kwesolwazi. Izinkontrola ze-MPPT zingathola amandla angaphezu kwezinye, nangalokho ngezinsuku zomkhovu noma ngezinsuku zomkhovu omncane. Lokhu kusho ukuthi zihambisana ngokuphelele kuzokugcina amandla ngokuphelele. Ngaleso sikhathi, yilokho okunika umphumela wokuthi yilokho okuhle kakhulu ukuthi usebenzise izinhlobo zezinsiza zokuphakama kwesolwazi. Ngaphandle kwalokho, izinkontrola ze-PWM zingempela kakhulu futhi zingaqinisekile kakhulu, kodwa zingaba zingasenzi ngokuphelele. Zihlanganisa izinsiza ngqo nezibhanki, okungabonakala ukuthi kuyadonsa amandla. Lokhu kusho ukuthi abaningi bakhetha i-MPVON ye-MPPT, ngoba zisave amandla angaphezu kwezinye futhi zifaka amabhanki ngokusheshayo. Indlela engenye yokuthi i-MPPT ihlukene kukuthi isebenza nezinsiza zezinhlobo nezinhlobo zezinhlobo. Lokhu kubonakalisa ukuthi abasebenzi bangakwazi ukudala izinsiza zokuphakama kwesolwazi zokufanelela kuzo ngokuphelele ngaphandle kokuzimela kwezinhlobo zokubonakala. Ngaphezu kwalokho, zisebenza ngamavolti angaphezu kwezinye, ngoko ke zisebenza ngokuphelele nezinsiza ezingaphezu kwezinye. Ngokujwayelekile, nangalokho i-PWM iyasebenza ngokuphelele kwezinsiza ezingaphezu kwezinye, izinkontrola ze-MPPT ziyasebenza ngokuphelele kuzokugcina amandla ngokuphelele kanye nokusebenza ngokuphelele.
