Interesting. Mine is a little tricky with 2 phases but allows me to have a constant. My inverter is on L2 so exports do not change that value. Depending on the house loads, this will sit 100-300W in the morning and ensures the battery is not full at 10 am. The array on the MPPT is east facing, so it starts charging at 5 am. I have my flow in the text file if you want to see how I tweaked it. It would be interesting to see if someone can make some improvements.
