Jackery HomePower 2000 Ultra vs Zendure SolarFlow 800 Pro 2
Technical comparison · All-in-one
Two home batteries of the same room-sized class, both with grid feed-in capped at 800 VA. What separates them is what happens when the grid drops: the Jackery supplies 1500 W with no interruption, the Zendure 1000 W with a brief pause (manufacturer-declared figures).

The differences that matter
- 4 MPPT trackers vs 2, up to 2640 W of solar vs 2000 W → with panels facing different ways, the Zendure works each string separately.
- Backup 1500 W uninterrupted vs 1000 W with a pause → on the Zendure the switch to battery leaves a short gap in power, and big loads must stay under 1000 W.
- Grid charging 2.3 kW vs 1 kW → the Jackery fills up much faster in the cheap tariff window.
- Floor-standing vs wall-mounted → decides where the space goes in the house.
Which one to choose
Choose Jackery HomePower 2000 Ultra if…
you want the router, fridge and computer to stay on when the power cuts, without the gap of switching over to battery. It handles time-of-use tariffs natively and charges faster from the grid, handy for filling up in the cheap hours. You give up two MPPT inputs, expansion beyond 8 kWh and wall mounting: this one stands on the floor.
Choose Zendure SolarFlow 800 Pro 2 if…
you have panels on several roof faces or at different angles, which four MPPT trackers handle each on its own. It mounts on the wall, keeps the floor free and expands to 11.5 kWh. The trade-off shows in an outage: lower output, a brief interruption when it switches to battery, and slower charging from the grid.
