Glad you are back up but the 12VDC fuse are on the 12V side of things... Should not have bothered anything on the 120VAC side of your power distribution panel...
Fuses just don't blow for no reason too haha...
Perhaps when you plugged into the 120VAC your battery overloaded the on-board converter/charger unit with the high DC current initial charge demand... Those two high rated FUSEs probably labeled REVERSE POLARITY are on the 12VDC distribution side between the converter DC OUTPUT and battery terminals...
Lets hope all is ok... good idea to check your battery fluids first thing in the morning.
