Thank you.
Brand notwithstanding - because only time will tell if they stick around and their warranty is worth anything - the Mega 1 at $300 is the best value available right now if for no other reason than it's easily hacked to use non-OUPES expansion batteries. I would double my budget if the Mega 2 dropped to $600 (it was $619 last month), but I don't think that'll happen any time soon, so I bit on this.
There are cheaper units out there if you don't want or need this capacity, of course.

I've been holding out for a 240v output unit with simultaneous charging for under $1k so I can power both sides of the panel during an outage for the entire house. I'm hoping maybe in the next two years or so we get to that price point.

I'm sorry you're dealing with the issue. Maybe their customer service can assist (I think I read a brand that had a firmware update that improved idle usage, but don't recall what brand that was)
From Project Farm. He did a review just a few weeks ago, and the Oupes had by far the worst idle usage of all brands.
