Magnum Inverter
Anybody mounted these upside down it said it could be done in the manual. If so can you show pictures.

If you mount it to an aluminum plate, the plate will aid in thermal transfer. If you space the plate off of any wood surface, the thermal transfer aid will increase quite a bit. Even 1/4" of space will facilitate a large increase in thermal transfer.
FWIW, I mess around with Large Class A amplifiers and heat transfer is always a concern. A 25W amplifier generates significant heat and the transistors need big heatsinks. Your inverter is a piker in comparison of thermal transfer needed. Space allowed is critical because of the active cooling. Hanging it upside down has little effect on the transfer since the fans inside don't care. Allowing for a space between the case and the mounting surface will aid in heat transfer. Using three washers between the case and the mounting surface on each bolt should allow for 1/4" of space. With a 12" x 12" case, that is 36 cu inches of air space, equivalent to a 4" x 9" vent above the case.
