I thought so too. Had the dealer check it out and they could not find anything wrong and of course could not duplicate the problem. Their finding was maybe it should have come with two batteries. They didn't offer to give me a second battery even though they were the selling dealer.
Anyway, I could not duplicate the problem again either, so maybe it was just a low battery of something. I'll likely never know. Seems I read somewhere that it is good to shut off the inverter when on shore power since the transfer switch has by passed it anyway. Easy enough to do.
I hope I just did not open another can of worms with that.
