sonnenBatterie 10 hybrid vs Zendure SolarFlow 4000 Mix Pro
Technical comparison · All-in-one
Both offer a 10-year warranty and 10000 declared cycles, but they are set up differently: the sonnenBatterie 10 hybrid is three-phase and in an outage moves to emergency mode with a declared pause of 5000 ms, that is 5 seconds; the SolarFlow 4000 Mix Pro is single-phase, IP65, and declares continuity in 10 ms (manufacturer-declared values).

The differences that matter
- Three-phase vs single-phase → the home's connection decides, before anything else.
- Emergency in 5000 ms (EPS) vs 10 ms (UPS) → with the first there is a pause of about 5 seconds in the supply; the second declares continuity.
- 2500 W vs 3680 W continuous, charging 2.5 kW vs 4 kW → how many loads run together and how fast it charges.
- IP30 vs IP65, -5 to 45 °C vs -20 to 55 °C → the second has wider protection and a wider temperature range.
