Anker SOLIX Solarbank 2 E1600 AC vs Jackery SolarVault 3 Pro Max
Technical comparison · All-in-one
Both cap grid feed-in at 800 VA, so what separates them is how much solar they can take. For one or two panels on a balcony the first is enough; anyone with several strings or roof faces in different directions should look at the second.

The differences that matter
- 1,200 versus 4,000 W of solar input, 2 versus 4 MPPT → how many panels and orientations you can connect without a second device.
- 1.6 versus 2.52 kWh (expandable to 9.6 and 15.12 kWh) → with a constant 400 W load, in theory about 4 hours versus about 6 hours, ignoring losses.
- Backup 1,000 W with a pause (EPS) versus 1,600 W in continuity (UPS) → with the grid down, more loads stay on and without a break.

Which one to choose
Choose Anker SOLIX Solarbank 2 E1600 AC if…
you have one or two panels on a balcony or carport, no more than 1,200 W in total: two MPPT inputs are enough. The trade-off: 1.6 kWh in the base module and, with the grid down, backup with a brief pause.
Choose Jackery SolarVault 3 Pro Max if…
you have several panels or roof faces in different directions: four MPPT trackers each handle their own string, with backup in continuity. The trade-off: 26.5 kg to stand on the floor.
