Here is something that really would be nice, add to the display the Differential reading between consumption and solar production. If total consumption is more than solar production then show the third display value as a negative and if solar production is greater than consumption then show the third display as a positive value. You could have the numbers turn red or green maybe. The two displays now are just the consumption total and the solar production so add a third that shows the Differential. Now that would be nice and very easy to add.
