Anker SOLIX Solarbank 3 E2700 Pro vs Jackery HomePower 2000 Ultra
Technical comparison · All-in-one
Two all-in-one systems that feed at most 800 VA into the grid. They differ in how many panels they take and in how they behave when the grid drops: four solar inputs and backup with a short pause on one side, two inputs and uninterrupted backup on the other.

The differences that matter
- 3,600 W solar input and four trackers vs 2,000 W and two → the first takes more panels, even with different orientations, each on its own tracker; on the second, extra panels stop paying off sooner.
- 1,200 W backup with a pause vs 1,500 W uninterrupted → in an outage the first restarts sensitive devices, the second does not and supplies more.
- Expandable to 16 kWh vs 8 kWh → the first leaves more room if storage will grow.
- Grid charging at 1.2 kW vs 2.3 kW → on a cheap hourly tariff the second fills up in less time.
Manufacturer-declared values.
Which one to choose
Choose Anker SOLIX Solarbank 3 E2700 Pro if…
your panels sit on several roof faces or orientations and you want a tracker for each, or you plan to grow the storage over the years. In an outage the power comes back after a short pause, so a device that cannot tolerate even that will shut down and restart.
Choose Jackery HomePower 2000 Ultra if…
you want the router, NAS and computers at home not to notice an outage: it switches over in 20 ms and carries a heavier load. The compromise is on the solar side: two inputs leave less room if the panels face different directions.
