2. The approved system must:

  • not be connected after the expiry date recorded on the approval
  • be connected via a Western Power approved import/export meter
  • be installed as detailed in the approved application (including diagrams) and, if special operating
    conditions are applied, to comply with the conditions before commissioning

to the integrity of the distribution system or does not conform with Western Power technical
requirements we may disconnect the equipment.
