Historic Data

I installed my system on 03/09/12 and have generated 34772kw hours up until 06/06/17 when I installed 3x1.2kw AC Battery storage system with Enphase monitoring system. I have yet to obtain my Enlighten and User ID numbers from the installer so that all the data can be added automatically. So in the interim I have added the few days up until today manually and once I have added these two missing numbers I imagine my manual inputs will be changed automatically (I assume). Which is all good but I would like to have the 34772 kw hours that I generated over the last five years somehow included in the database but I notice that there is no provision for me to do that. I have only added the above information in the remarks/comments space at this stage.
Is there a way of including this historic data in the world database?

Historic data can be uploaded in CSV format -

Thanks for the information. Unfortunately the only statistic I have is the aggregate figure for the five years. The input mechanism only allows for daily entries and that information was never recorded.
Anyhow I have the total energy generated recorded in the database so it may prove useful for the world aggregate-if it could be manually added.
Cheers.
