A battery is not connected to mains, so does not need PE.
However, neutral IS connect connected to mains.
Either:
- disconnect from mains and leave it floating,
- Have double isolation
- Add PE connection.
Do note that 110Vdc is, is Europe, within the Low Voltage Directive scope and battery powered also means either EMC or LVD directive (I do not remember which).
