Inverter not charging

[cottageman]

I've got an AIMS 24v inverter that's connected to solar and a propane generator. Generator runs as a backup but ebony bringing up the battery power fully up. It just sits at 24v. it rises quick to 24v then just sits at that level no matter how long it runs. Solar gets the batteries up to 29+ volts.
Any ideas why?
