Does the firmware need to be upgraded? Where can I find the current firmware version on my EB3A? Does Bluetti list firmware versions on their web site?
My “ECO” mode is stuck on 4 hours. No matter how many times I try to choose 1 hour, it won’t change.
So far, no help from Bluetti ‘customer service’. If that doesn’t change, I’m going with ECOFLOW from now on.
You update he firmware through the Bluetti app. You need it to update. Also you can turn off the ECO mode through the app as well as enable “powerlift” mode.
