I'd verify voltage output directly at the battery too with a multi meter. I would assume that the Edge is likely accurate, but not knowing what else is wired in to where it is sensing voltage from you could be seeing voltage drop through other parts of a circuit and not getting a true reading. It's like when you wire a volt gauge you should always wire it directly to the alternator's gauge pin (if it has one) instead of just plugging it in to a 12v keyed spot in the fuse box or finding a 12v keyed source under the dash somewhere and using it. Without knowing the voltage draw of other things hooked to the circuit, the resistance of the wiring,etc. the reading from those other sources can be erroneous.
Also, how new is it? Sometimes a brand new unit needs to run in for a bit before it starts regulating properly. That sounds weird, but I've had that happen on two different alternators and once they had been spun up and down a few times they put out 14.2-14.4 volts like nobody's business.
