What is marketing

“Save up to $6,000/year” and “3-year ROI” depend on time-of-use rates, solar, and climate. We do not repeat those as facts. The 45 kW surge figure is EcoFlow’s; we have not measured it.

Versus Powerwall 3

Ultra X can match or beat 11.5 kW on paper and you can order it. Powerwall has a 10-year warranty, a mature installer network, and 185 LRA in writing. Ultra X’s public warranty is shorter. If both quotes are ~$13k–$16k installed, pick based on who will service you in five years, not on a teal CTA.

Who should buy it

Someone who wants automatic backup, will pay five figures, and does not want to wait on Tesla. Pair SHP3 if you want circuit-level shed. Skip it if a $2,000 F3800 covers your actual loads — run the calculator first.
