Have just carried out the a SmartBMV 712 firmware update, v4.12 and now it is not showing me the current SOC ,consumed Ah or time remaining. Have previously updated without issues.
The fixed display is flashing "charge" which I have not seen before.
My system comprises 450Ah Victron smartLithium batteries with a Victron Multiplus 12/3000/120 charger inverter.
Any thoughts?
