Die Mannschaft took the lead through Mario Gotze early in the second half but were pegged back by goals from Andre Ayew and Asamoah Gyan. However, a strike from Miroslav Klose earned them a draw in their Group G match.
Low told reporters: "Ghana did a good job. They succeeded in closing down space, we weren't able to get the open spaces.
"It was an incredible high pace and the players gave everything. We wanted to avoid a hard fight with these temperatures. The team showed a strong morale to come back after we were down."
Germany are currently top of Group G and face the United States in their final match in the group stages.
