Electra Molins 7 kW generator problem

Good afternoon engineering team.

I am writing to you from Ukraine, engulfed in darkness due to Russian missile strikes.

We are trying to survive by the methods we love, so I am asking for your help.


Good people from Spain gave me an Electra Molins 7 kW generator.

But there is no voltage regulation unit in the generator.


I am attaching a photo of the generator and the removed cover.

Please advise me how to run it. Which AVR is suitable for this generator.

I'm writing to you with the help of Google Translate, so I'm sorry if I write illiterately.
