The differences that matter
- Backup 1600 W in continuity vs 2400 W with a pause → how much you can power, and whether sensitive loads stay on or restart (values as declared by the manufacturer).
- Floor vs wall → where it goes in the house.
- Expansion up to 15.12 kWh vs 16.8 kWh → how much battery you can add later.
Which one to choose
Choose Jackery SolarVault 3 Pro Max if…
you have equipment that cannot tolerate a gap in supply and 1600 W of backup is enough (UPS, declared 20 ms switchover). You also get 4000 W of solar input across four trackers and grid charging at 3.68 kW. It stands on the floor.
Choose Zendure SolarFlow 2400 AC+ if…
you want it on the wall and 2400 W of backup, with expansion up to 16.8 kWh. You accept a brief interruption at switchover (EPS) and that the app is needed for the first power-on.
