Does a battery system solve this mid day export problem?

  Yes, it prevents the house with the battery from being a tax on the grid. However, the capacity factor of both the solar and the battery is less than if they were deployed centrally. Again: residential solar isn't worthless, but in many places we've reached the point of diminishing returns where any additional capacity is much less useful-- unless there's an ancillary benefit that justifies it (like backup power for your house when deploying storage).
