How is the "Self Consumption" percentage in the Renewable tile of a report calculated?
Because for April, my "Self Consumption" is 57.32% but 51% of my energy has been Solar to the home, and a further 38% battery to the home (and the battery has been charged almost exclusively from Solar) so to me I would say my Renewable Self Consumptions as been more like 89%.

It further doesn't make sense if I look at a month like January, where my old battery was essentially out of commission anyways and I had 10% solar to home and 85% grid to home. But my Renewable Self Consumption is 56.72%?
