Public copy of data and outputs from 2022-08 analysis of likely optimal Eddi PV diverter Energy Margin level in PV / battery / heat-battery system
See paper at https://www.earth.org.uk/eddi-diverter-export-margin-analysis.html
The conclusion was to raise (at the end of 2022-08, manually via the control panel) the fixed eddi Export Margin from 100W to 400W nominal, expecting that to be more grid-friendly in a number of ways, without any significant loss of DHW from diversion.
