Momwe mungasankhire chowongolera cha MPPT ndi PWM mu TORCHN off-grid solar system?

1. Ukadaulo wa PWM ndi wokhwima kwambiri, wogwiritsa ntchito dera losavuta komanso lodalirika, ndipo uli ndi mtengo wotsika, koma kuchuluka kwa magawo omwe amagwiritsidwa ntchito ndi otsika, nthawi zambiri pafupifupi 80%.Kwa madera ena opanda magetsi (monga madera amapiri, mayiko ena ku Africa) kuti athetse zosowa zowunikira ndi machitidwe ang'onoang'ono a gridi yamagetsi a tsiku ndi tsiku, tikulimbikitsidwa kugwiritsa ntchito PWM controller, yomwe ndi yotsika mtengo komanso yokwanira. kachitidwe kakang'ono tsiku ndi tsiku.

2. Mtengo wa MPPT wolamulira ndi wapamwamba kuposa wolamulira wa PWM, wolamulira wa MPPT ali ndi mphamvu zowonjezera zowonjezera.Woyang'anira MPPT adzaonetsetsa kuti gulu la solar nthawi zonse likuyenda bwino kwambiri.Nyengo ikazizira, kuwongolera kokwanira koperekedwa ndi njira ya MPPT ndi 30% kuposa njira ya PWM.Choncho, wolamulira wa MPPT akulimbikitsidwa kuti azitsatira machitidwe a gridi omwe ali ndi mphamvu zokulirapo, zomwe zimakhala ndi chigawo chachikulu chogwiritsira ntchito, makina apamwamba kwambiri a makina komanso kusintha kosinthika kwachigawo.
