Jackery SolarVault 3 Pro Max vs Zendure SolarFlow 1600 AC+
Technical comparison · All-in-one
Same class, the same 800 VA feed-in limit and the same 6,000 declared cycles: what changes is how they behave when the grid is down and how they are installed. These are differences of set-up.

The differences that matter
- Continuity (UPS) versus backup with a pause (EPS) → loads either stay on without a break or stop for an instant when the battery takes over.
- Maximum charge 3.68 versus 1.4 kW → to fill from empty, in theory about 40 minutes versus about 1 hour 20, ignoring losses.
- 2.52 versus 1.92 kWh → with a constant 400 W load, in theory about 6 hours versus about 5 hours, ignoring losses.
- Floor-standing versus wall-mounted → decides where in the house it can go.

Which one to choose
Choose Jackery SolarVault 3 Pro Max if…
you want it on the floor in a cellar or garage and want a blackout not to interrupt your loads, with 1,600 W of backup. The trade-off: 26.5 kg to stand on the ground, and it does not hang on a wall.
Choose Zendure SolarFlow 1600 AC+ if…
you have little floor space and prefer to hang it on a wall, with add-on modules up to 11.52 kWh. The trade-off: a brief pause in backup and 1,400 W of power; for standards it declares only the CE mark, where the other cites VDE-AR-N 4105 and IEC 62619.
