If you leave the genny in long enough, or go on shore power, that number should continue to go down until you reach the "float" stage, meaning the battery is charged.
It is always a good idea to have the batteries load tested. This is a special tester that puts a high current low resistance load for a brief period to determine the capability of the battery to sustain a discharge. I have one of these testers and have used it many times. Battery shops and most repair places have them. Always a good idea to have batteries tested.
It is very important that you monitor the battery electrolite levels. If the plates are not immersed in electrolite they will will be damaged. So ensure you add distilled water to the batteries if they the type that you can fill. These would be flooded lead acid batteries. Good idea to test each battery cell with a hydrometer also. This will give you an idea of the charge per cell.
The other battery type would be AGM (Absorbed Glass Mat). There is no maintenance to these except ensuring all connections are clean as one must do on all batteries.
Bottem line: Your converter is working because the number has gone down and it should continue to go down as the batteries charge further.
Good luck and I suggest you keep a a very close eye on the batteries, keep the electrolite up and everything clean, including taking the connections off and buffed off,
Hope I was helpfull.
