So as one problem appears to get resolved (the issue of DESS settings not being applied) another one appears.
For the last 2 days the system had been forecasting consumption levels above total solar production, but has not charged the battery from the grid during the cheaper, overnight rate.
Yesterday the system ran with grid per most of the day, with solar barely sustaining the load and only putting maybe 3 or 4% into the battery. With similar forecast for today, the system has run on grid power all night and the battery has not charged. Forecast for today is still more consumption than production.
Is there a way to revert back to a previous VRM or whatever, from about a month ago, as these problems seem to have arisen in the last couple of weeks.
