Hi,
Both Surge Guard and Progressive Industries have a low voltage cut off at 104. That's too low for my comfort zone.
I think the Sola unit is great
Is it Sola in the picture by Briansue?

If I read it correct, when voltage drops to 90 - you'll get 109, and when it shoots to 150 - you'll get 134. Doesn't look too comfortable.
Is there anything with 30A input that keeps output 110V+-4% withing say, 90-155V input range, and shuts down when it can't keep it? Not just a "mejor voltaje", but "correcto voltage"?
