Brand comparison
Two brands that compete on the same shelf at every size, both LiFePO4 across the current range. The differences are in inverter rating, solar input, expandability and price per watt-hour, and they change by class.

Medians are computed over the units each brand currently sells on its US store, so a brand with more whole-home units will show a lower median price per Wh. Compare within a class below before reading the scorecard as a verdict.
Per class, the better value between the two brands, with the unit that gives more output and the one that refills faster from a panel named beside it. The solar recharge calculation explains how capacity and the input limit translate into hours of sun.

Start from the load, not the brand: the sizing calculator gives the Wh, running W and surge W you need, and its table shows which units from both brands clear it. Among those, the columns above that differ most betweenBLUETTI and EcoFlow are price per Wh, maximum solar and AC input (how fast a unit refills), whether extra batteries attach, and whether a UPS switchover time is stated at all. Warranty length is a stated fact; how a claim is handled is not something a spec table can tell you.
BLUETTI has the lower median price per watt-hour across its current range ($0.50 against $0.61). Within a size class the answer can flip; the per-class tables above are the honest comparison.
Cycle life is a maker's rating, and both brands' current LiFePO4 units state ratings in the thousands of cycles where they state one at all. Compare the cycles column and the capacity it is rated to; the LiFePO4 vs NMC guide explains why the rating share matters as much as the count.
The unit with the higher maximum solar input for its capacity refills faster from the same panel; the solar page lists hours of sun to refill for every unit. Between these two brands the answer changes by class, which is why the cards above name one per class.
