hi , is there any reason that i shouldn't connect my tv and 12v skybox to the load terminal on my mppt solar charge controller? tv is 30 watts and box is 18 watts. at the moment i power them from the cigarette lighter socket behind the tv but the wires are very small and travel about 8 metres before they get to the sargeant power supply and then another 4 metres to the batteries which i'm sure wastes power . cheers sean
