Renegade Motorhomes always mounts the Magnum inverter upside down (picture added) and no one has ever reported an issue. If I do the same with a Victron Multiplus Inverter/Charger will all of the electrons fall out? Just kidding. Seriously though, anyone know if a Victron Multiplus can be mounted in the same manner? The Multiplis manual states vertical mount is preferred for cooling but that horizontal mount is allowed. It's vague on if it absolutely must be mounted on a horizontal surface though.
