Have chosen the installation of the inverter near the battery to use the original cable. In winter, the battery of my mobile home but on the auxiliary heating (which is in winter yes occasionally needed) with heating. This can not stand the inverter and on continuously from .. therefore no coffee !! Even the insertion of the coffee in the WMF coffee machine is somewhat cumbersome .. we have often a "foot bath" served ... therefore always produce machines in a "Töpfle".
