    Just installed it

    Posted by Unknown on 20th Oct 2017

    I received the generator fast and in excellent condition. The electrician who installed it mentioned several times it was a superb generator, one of the best he said. We did not have a blackout yet but several times testing the unit it worked like a charm, the switching between generator and the line. I can give this this generator the tumbs up.
    I will update this review if needed.
