Solax Energy Integration

Very excited about the energy integration. I wonder though if anyone can share any insights in relation to the Solax integration. The integration by itself seems good and I get many stats from it. When it comes to the HA Energy integration though I am limited in my Solax options with the actual correct entities not being available.
Below is a capture of my available options as you can see they quite limited and dont really help in pulling through the correct data

Also where I have a custom Lovelace GUI is there a neat way of adding the energy flow diagram as I cant seem to find where to do that.

Thanks in advance
