Two transistors switched on at 50Hz rate and for 25% of the time each (180 deg phase difference). They connectt the battery pack voltage on the primary of the transformer (in opposite directions).
The reason the output voltage ramps downwards toward 0v is possibly the increased on-resistance of either the transistors, increased resistance of the battery pack or likely increased resistance of the primary coil. They probably used too thin wire for that, to save some cost.

Wow, I never thought that the output of a modified-sine inverter looked this awful.
