I have deactivated ESS Dynamic and it seems that the CerboGX will no longer charge the battery. It continues to export to the grid and continues to charge the battery at the same rate. If I deactivate the export, it reduces the amount of energy produced by the Fronius. If I raise the minimum charge …
