The Maraton one looks good with the 4.7Kw max output.
$.7 Kw will go a long way ion a power outage,especially if you also have heat and hot water.
But I’d like to see one that can maintain 10 to 15 Kw to
be able to completely function off the grid, and be able to run my AC at the same time as my fridge, microwave, TV, laptop, router, modem and a couple of lights as well.
....I want it all...and I want it yesterday! ;o)
