Why these requirements?

Whole-house backup means feeding several circuits at once through a transfer switch or a home panel kit, so the list needs at least 3,600 W continuous and 3,000 Wh in the main unit, and room to grow to 10,000 Wh or more with extra batteries for multi-day outages. Every model here is portable and plugs into the house through an inlet or panel; none is a permanently installed wall battery. Sorted by maximum expanded capacity.
