I am attempting to charge my 2014 smart ED from a bank of 12 volt batteries charged daily with solar panels. I tried charging with a pure sine wave inverter, but my factory charger refuses to operate off of the inverter. I am not sure why it does not like the electric. I was thinking maybe a different charger like the clipper creek might work. Any suggeestions would be greatly appreciated.

It may be complaining about grounding. Make sure the output of your inverter is setup correctly with the neutral grounded.
Some folks had the same problem trying to charge from a generator and needed to add a resistor from neutral to ground to fake it (some generators don't like neutral shorted to ground).

And yes, a different EVSE might work, because it might have different thresholds for detecting grounding problems. But better to fix the problem.
