How does this work? It's labeled whole house but I'm seeing 7200w output. Even a 100amp service is 24kw so how does this actually connect into your panel? Does this mean the my main panel needs rewiring to move high priority circuits?

It isn't truly whole house without much more than this kit. You could do what you're suggesting with their panel which costs more, but only with the high priority circuits.

It powers your entire homes essential loads, not every single outlet throughout. With 10 intelligently managed circuits, you can keep your lights, refrigeration, internet, security systems, heating/cooling, and critical outlets running for hours or even days, depending on your usage. It can surge to handle 15kw demands like large air conditioning compressors.

The 18kWh capacity means you could theoretically run a 500W load for 36 hours. In a real-world scenario, with careful management, this could power a typical home's essentials for about one to two days, and it's a seamless transition the moment the grid goes down.

At 18,000Kw you can run your whole house as long as your AC is under 4 ton. You will need the smart panel and about 5,000W in solar panels. So roughly about another $3,000 and your go to go.

I like the simplicity of this system, but just throw the latest 300lb 16kWh battery on a hand truck (Ecoworthy or Humsenk) along with a cheap split phase inverter for either brand for like 2.5k all in.

They serve the similar purpose but this requires zero installation if you already have a transfer switch - simply hook up its 240V output to your transfer switch and call it a day.
