No -- the batteries are hooked up to the DC power distribution fuse panel. So the converter charge system sends DC to the batteries to charge them then the batteries send power back to the converter power distribution to go to all the rv wiring.
Here is a booklet on the WCDO converter. Go to page 6 and you'll see how the batteries are connected to the DC load panel.
