A single Delta Pro Ultra from EcoFlow costs $5,799 and scales up to 90kWh of battery capacity, 16.8kW of solar input, and 21.6kW of AC output, which is enough to power central air conditioners.

Ecoflow announced the Delta Ultra today at CES, its monster 6kWh home LFP battery pack on wheels. Its 240V/30A= 7.2kW output can back up a home the way a whole home generator or Tesla Powerwall can.

That means if I use the Delta Pro Ultra’s full capacity (90% of 6.14kWh because it won’t let you use 100%) in a single day, I can save a maximum of 94 cents per day, or $343 per year.

The Delta Pro Ultra comes with extended outages and daily use, with a single unit capacity of 6kWh, 7200W output and 5.6kW of solar input, which could run an entire home.

While the Smart Home Panel 2 isn't required to make the Delta Pro Ultra work, it's a good idea. The Smart Home Panel 2 allows you to finely manipulate how the battery will power your home.
