I don't know that 12.3 volts indicates you have a problem. While charging the battery, the voltage should take a while to reach 14 volts like the red curve at this link:

Also, you might double check the bus voltage with a known good multimeter and compare it to what your EFIS reads. Mine is off by ~1.5 volts for some reason.
That being said, you should see some jump in voltage as the regulator starts charging the battery. Were you also reading 12.3 volts before starting the engine?
My voltage seems to take 20-30 minutes of flight to stabilize at a peak value. I don't know that I'd be able to draw many conclusions from running for a few minutes on the ground at 2000rpm.
