Espero que a moda espalhe para as marcas mais conhecidas que têm representação em Portugal...The ACDC12(B) hybrid solar air conditioner runs on DC power directly from solar panels, without needing an inverter, a
charge controller, or batteries. The solar DC power directly replaces and significantly reduces the power normally required
from the utility grid and can cut daytime energy costs for air conditioning by up to 80-90%.
