As I just received my AC200P I wanted to know how new (as a revision) my unit is. Looking at some of the issues, I think it’s good to have a kind of change history of the different revisions of SW and HW and try to link the features/issues with respective revisions. Pity that one can not reflash the device with new firmware, but it may be useful nonetheless.
I assume it is the graphical interface (Human-Machine Interface). It is really strange. They may have rolled it back due to some reason? But I know that the earlier versions of the software were reporting a lot of diagnostic details, and the later just removed it. And mine shows virtually nothing.
Having revision history with associated issues or features, gives some predictability to the owners of the AC200P on what to rely and what to consider. We shouldn’t forget, that many consider solar generators as a back-up solution for crisis situations, so to know on what to count (or not) is crucial.
And it is just a self-illusion that a device like EB240 is “just a battery” - the charging controller, BMS, inverter - everything is smart and everything has software (you may call it firmware, it’s still the same) in it. That the HMI is more simple in those models doesn’t make them SW-free.
