I have a hybrid inverter GIV-HY5.0 with firmware version D0.309-A0.309.
Additionally 3 x 9.5 kWh batteries with firmware version 3015
I am attempting to update the battery firmware to version 3017 using GivEnergy Cloud, but on three occasions this update has failed.
Do I need to turn off the battery Eco mode to update? Is there any other issues that I need to be are off?
Thanks in advance.
