EcoFlow STREAM Ultra X vs Jackery HomePower 2000 Ultra
Technical comparison · All-in-one
Same 2000 W maximum solar input, same grid charging and same 800 VA feed-in limit: what decides is how far the battery can grow and how it behaves in a blackout. Power figures are manufacturer-declared values.

The differences that matter
- MPPT inputs: 4 against 2, at the same 2000 W of solar → the EcoFlow splits the panels across more independent strings.
- Expansion: 23 kWh against 8 kWh → the EcoFlow can grow far beyond its starting capacity, the HomePower stays a compact system.
- Backup: 1200 W with a gap against 1500 W without interruption → only the HomePower keeps running, without a restart, whatever cannot tolerate an interruption.
- Mounting: wall (38.8 kg) against floor (26 kg) → the EcoFlow needs a suitable wall and two people to lift it.
Which one to choose
Choose EcoFlow STREAM Ultra X if…
you are starting with one battery and know you will add more, up to 23 kWh, or you want to run the system over the local network or through Matter from a home-automation setup. The trade-off: it weighs 38.8 kg to hang on a wall, and in a blackout there is a short gap (EPS) with 1200 W available.
Choose Jackery HomePower 2000 Ultra if…
you want the router and computers to stay on when the power drops: the UPS switches over in 20 ms and delivers up to 1500 W. It stands on the floor, 26 kg, with no drilling. You accept two MPPT inputs instead of four and an expansion limit of 8 kWh; the app is needed for the first start-up.
