I don't know if anyone else has had this problem, i updated the firmware on my smart lithium batteries (mandatory updates V1.24) through the Victron Connect App, all of which were working perfectly before, now some of them even though the firmware stated completed, now come up with a E-SL24 hardware failure alarm and a E-SL2 internal communications failure, the recommendation is to reinstall the firmware to reset the controllers but you cannot do this as the App states "your product is already running the latest firmware version"...
The batteries are:-
24V 200AH smart LiFeP04
12V 90AH smart LiFeP04
Any ideas as i do not want have to replace these perfectly good batteries.
Regards
Steve
