Usazamana nokuba yeyiphiumlawuliukuthenga?Isilawuli sincinci kakhulu ukuhambelana namandla elanga?Ithetha ukuthini iMPPT kunye nePWM?Musa ukuphaphazela, emva kokufunda eli nqaku, ukhethe okulungileyoumlawuliakukho nzima.
Uhlobo lomlawuli?
Umlawuli weMPPT: Iyakwazi ukubona umbane wokuvelisa amandla epaneli yelanga ngexesha langempela, kwaye ulandele i-voltage ephezulu kunye nexabiso langoku, ukwenzela ukuba inkqubo inokuhlawula ibhetri ngokuphuma kwamandla aphezulu.Kwimozulu enokutshintsha rhoqo ukukhanya kwelanga okanye imozulu enamafu, inokufunxa ubuncinci amandla angama-30% ngaphezu komlawuli we-PWM.
Umlawuli we-PWM: oko kukuthi, ukulawulwa kobubanzi be-pulse, okubhekiselele ekulawuleni isiphaluka se-analog kunye nemveliso yedijithali ye-microprocessor.Yindlela yokufaka ikhowudi yedijithali kwinqanaba lesignali ye-analog.Xa kuthelekiswa nomlawuli weMPPT, ixabiso liphantsi.
Abalawuli be-MPPT kunye ne-PWM zimbini zobuchwepheshe, nganye ineenzuzo zayo, ixabiso le-PWM lingcono, kwaye umlawuli we-MPPT unokuguqulwa okuphezulu kunye nokusebenza okunamandla.
Indlela yokukhetha isilawuli oyifunayo?
Nazi izinto ezimbalwa ekufuneka uziqwalasele:
1. Jonga inkqubo yohlengahlengiso.Nokubaumlawuliilungele inkqubo ye-12V/24V/36V/48V
2. Jonga ubuninzi be-voltage yegalelo lepaneli yelanga.Qinisekisa imowudi yokudibanisa yeepaneli zelanga.Emva koqhagamshelo lwechungechunge, i-voltage iyanda.Nokuba ludibaniso oluluchungechunge okanye unxibelelwano oluhambelanayo, alukwazi ukugqitha ubuninzi bevolthi yegalelo leepaneli zelanga ezilawulwayo.
3. Jonga amandla amakhulu egalelo lepaneli yelanga.Oko kukuthi, amandla amakhulu okufakwayo kwenkqubo ye-photovoltaic inquma ukuba zingaphi iipaneli zelanga ezinokufakwa
4. Jonga ibhetri ekalikelwe yangoku kunye nodidi lwebhetri
