Ngisazabalaza nokuthiisilawuliukuthenga?Isilawuli sincane kakhulu ukufanisa amandla elanga?Isho ukuthini i-MPPT ne-PWM?Ungethuki, ngemva kokufunda lesi sihloko, ukhetha okulungileisilawuliakunzima.
Uhlobo lwesilawuli?
Isilawuli se-MPPT: Singakwazi ukubona i-voltage yokukhiqiza amandla wephaneli yelanga ngesikhathi sangempela, futhi ilandelele i-voltage ephezulu kakhulu kanye nenani lamanje, ukuze uhlelo lukwazi ukushaja ibhethri ngokuphuma kwamandla aphezulu.Esimweni sezulu esinokushintsha njalo kwelanga noma isimo sezulu esiguqubele, singamunca okungenani amandla angu-30% ngaphezu kwesilawuli se-PWM.
Isilawuli se-PWM: okungukuthi, ukulawulwa kobubanzi be-pulse, okubhekisela ekulawuleni umjikelezo we-analog ngokuphuma kwedijithali kwe-microprocessor.Kuyindlela yokufaka ikhodi yedijithali izinga lesignali ye-analog.Uma kuqhathaniswa nesilawuli se-MPPT, intengo iphansi.
Izilawuli ze-MPPT kanye ne-PWM ziwubuchwepheshe obubili, ngayinye inezinzuzo zayo, intengo ye-PWM ingcono, futhi isilawuli se-MPPT sinokuguqulwa okuphezulu nokusebenza okunamandla.
Ungasikhetha kanjani isilawuli osifunayo?
Nazi izinto ezimbalwa okufanele uzicabangele:
1. Bheka uhlelo lokuzijwayeza.Ukuthiisilawuliilungele isistimu ye-12V/24V/36V/48V
2. Bheka i-voltage ephezulu yokufaka yephaneli yelanga.Nquma imodi yokuxhuma yamaphaneli elanga.Ngemuva kokuxhumeka kochungechunge, i-voltage iyanda.Kungakhathaliseki ukuthi iwuchungechunge loxhumano noma uxhumano oluhambisanayo lochungechunge, alukwazi ukweqa umthamo omkhulu wevoltheji wokufaka wamaphaneli elanga alawulwayo.
3. Bheka amandla okufaka aphezulu ephaneli yelanga.Okusho ukuthi, amandla okufaka aphezulu wesistimu ye-photovoltaic anquma ukuthi mangaki ama-solar panel angafakwa
4. Bheka ibhethri elilinganiselwe lamanje kanye nohlobo lwebhethri
