Ecoflow DELTA Pro - Error 022
Hello, I'm in despair: I bought a brand new Ecoflow DELTA Pro for my parents as they are experiencing countless power outages. The unit was connected to the devices (lights, small fridge) when the power went off, and it worked. When the power went off again a few hours later, we tried connecting the unit but this time it wouldn't turn on.The display blinks 2-3 times, I hear a beep also 2-3 times and error 022 is shown in the screen. Then the unit shuts itself off.I have tried the Hard Resert recommendation (pressing the power button for 10 seconds or more without any device connected), but the error persists. Any help will be much appreciated.
