I have enabled the new wind/solar priority sustain mode on my Multiplus.
After one week on Sustain, battery had dropped to about 70%, as there was hardly any sun the first week.
As expected the multiplus dropped out of Sustain as SOC never reached 100% during the week.
When it dropped out it seemed to stay at float at 90% SOC for several days.
What actions will trigger the Multiplus to go back to Sustain again after this?
