This is a very good deal at just 21 cents per Wh for an All-in-one solution. I keep a super close eye on this stuff, and this is about as good a deal as I've ever seen. The only thing close was the Oupes exodus 2400 when it was on sale for $420 but no longer is, which makes this deal the current reigning King of price per Wh for a reputable name All-in-one solution. The only con I see with this is that the typical user won't need this much power and capacity, so it's overkill for most people. With all that being said, count me in for 1. Thanks OP. Great find!
