Anker SOLIX Solarbank 4 E5000 Pro vs EcoFlow STREAM Pro
Technical comparison · All-in-one
These are not systems of the same size: the Solarbank 4 E5000 Pro stores 5.02 kWh and accepts up to 5000 W of panels, the STREAM Pro 1.92 kWh and up to 1500 W. Both declare the same 800 VA feed-in limit, so size decides how much energy you store and how many panels you connect, not how much goes to the grid; values are declared by the manufacturer.

The differences that matter
- Solar input 5000 W vs 1500 W, four MPPT trackers vs three → how many panels, and on how many roof faces with different orientations, you can connect.
- 5.02 vs 1.92 kWh, 50 vs 22.8 kg → the energy you store grows with the weight you have to install.
- Backup power 2500 W vs 1200 W → how many devices stay on together in a blackout; both are EPS, with a brief interruption.
- Feed-in limit 800 VA on both → what goes to the grid does not change with the size.
Which one to choose
Choose Anker SOLIX Solarbank 4 E5000 Pro if…
you have many panels or several roof faces to connect, up to 5000 W across four MPPT inputs, and want 5 kWh of storage that runs loads up to 2500 W in a blackout. The inverter is included. You handle and install 50 kg, and feed-in stays capped at 800 VA.
Choose EcoFlow STREAM Pro if…
you want the smaller system: up to 1500 W of panels on three MPPT inputs, 1.92 kWh, 22.8 kg. It lists native hourly tariffs and keeps running, in reduced mode, without internet; the first start-up needs the app. In a blackout it gives 1200 W instead of 2500 W, and the inverter is listed as not included.
