Please confirm the following

• I believe this issue is a bug that affects all users of OpenDTU-OnBattery, not something specific to my installation.
• I have already searched for relevant existing issues and discussions before opening this report.
• I have updated the title field above with a concise description.
• I have double checked that my inverter does not contain a W in the model name (like HMS-xxxW) as they are not supported.

In my opinion, this is not a bug and not an error in openDTU-OnBattery: As you write, the inverter is flashing red, which means it has not restarted after the power failure.
Did you disconnect the inverter (again) and plug it back in after about 15 minutes?

Did you measure/check with a "consumer" whether there is mains voltage at the socket?

These tests only make sense when it is light in your area and the PV modules can produce electricity.
