EcoFlow STREAM Pro vs Zendure SolarFlow 800 Pro
Technical comparison · All-in-one
Two all-in-one systems with the same energy and the same grid feed-in limit: they differ in how many panels they take on the solar side and in how much they carry in an outage.

The differences that matter
- 1,500 W solar input and three trackers vs 2,640 W and four → the second takes more panels and more orientations; both feed at most 800 VA to the grid, so extra panels mainly fill the battery faster.
- 1,200 W backup vs 1,000 W → 200 W more: the difference between also running a small appliance or not.
- 22.8 kg vs 25.9 kg → three kilos less to carry up to a wall or into a cellar.

Which one to choose
Choose EcoFlow STREAM Pro if…
in an outage you want to run more than just the router, and your array is modest, say two or three balcony panels. The compromise is on the solar side: it does not take more than three strings.
Choose Zendure SolarFlow 800 Pro if…
your array has more panels, even facing different ways, and you want each on its own tracker. In an outage it delivers less power, so bigger loads stay off.
