EcoFlow STREAM 5000 vs Jackery HomePower 2000 Ultra
Technical comparison · All-in-one
Both are all-in-one systems with feed-in limited to 800 VA, and what decides is how much solar you can connect and how they behave in a blackout. STREAM 5000 takes up to 5000 W of solar and gives 2500 W in backup with a brief pause; HomePower 2000 Ultra stops at 2000 W of solar and 1500 W backup, with a declared 20 ms switchover (manufacturer-declared values).

The differences that matter
- Solar input: 5000 W and 4 MPPT versus 2000 W and 2 MPPT → how many panels and independent groups you can connect.
- Backup: 2500 W with a pause (EPS) versus 1500 W with a 20 ms changeover (UPS) → the first powers more loads but with a brief interruption, the second fewer loads with a faster switch.
- Expansion: up to 15 kWh versus 8 kWh → the ceiling you can reach with add-on modules.
- Weight: 45.4 kg versus 26 kg → how hard it is to move and mount.
Which one to choose
Choose EcoFlow STREAM 5000 if…
you have several groups of panels to connect — 4 MPPT trackers, up to 5000 W — and want 2500 W of backup power, with expansion up to 15 kWh. You accept a brief interruption at a blackout before power returns, and 45.4 kg to place on the floor.
Choose Jackery HomePower 2000 Ultra if…
the solar array is modest, up to 2000 W, and you want the switch to backup to happen with a declared 20 ms changeover; it starts from 1.945 kWh usable. In return you get 1500 W of backup instead of 2500 W, 2 MPPT trackers, expansion to 8 kWh, and the app is required for first power-up; it weighs 26 kg.
