■ The catch — co-equal billing, always
It's portable, not a backup system. 2.07 kWh and 2,600 W means no 240V, no split-phase, no transfer switch — you plug appliances into it rather than backing up the panel, and central AC or an electric range are out of the question.

The vanished 30% credit
The One Big Beautiful Bill Act killed the 30% federal 25D credit for homeowner-owned batteries finished after 2025-12-31 — and the IRS counts the expenditure when installation is *completed*, so a 2026 install gets nothing. That is $3,500–$5,500 of real cost added back to an installed system. Not tax advice.
Surge watts aren't run watts
Continuous (rated) wattage powers your loads; peak/surge figures last 3–10 seconds and only cover motor-start inrush. A single 13.5–15 kWh battery rarely runs central AC and an electric range at the same time without load management.
Whole-home math
True whole-home coverage needs 30 kWh+ of usable storage — most homes start with one 10–15 kWh unit on critical circuits (fridge, lights, internet, well pump). And installed quotes of $11,500–$18,500 per battery include labor and permits, while Amazon prices are hardware-only.
