Anker SOLIX Solarbank 2 E1600 AC vs Anker SOLIX Solarbank 4 E5000 Pro
Technical comparison · All-in-one
Two balcony batteries with a built-in inverter and the same 800 VA feed-in limit, so the question is not how much power reaches the house but how much sun you can collect and how much of it you keep for the evening. On the manufacturer's declared figures, the difference that matters is 1.6 kWh with 1200 W of solar input against 5 kWh with 5000 W.

The differences that matter
- Solar input, 1200 W on 2 trackers vs 5000 W on 4 → how many panels you can connect before the input starts limiting them.
- Capacity, 1.6 kWh vs 5.024 kWh → how much of the day's surplus is still there after sunset.
- Emergency output, 1000 W vs 2500 W → how many appliances you can run together without the grid.
- Feed-in, 800 VA on both → the grid receives the same; what changes is how much you store.
Which one to choose
Choose Anker SOLIX Solarbank 2 E1600 AC if…
You have a balcony or a small roof with two strings of panels, up to 1200 W in all, and want to shift the day's surplus to the evening: 1.6 kWh does that job, and capacity can be added later. You accept that the emergency output stops at 1000 W during an outage and that the input takes nothing above 1200 W.
Choose Anker SOLIX Solarbank 4 E5000 Pro if…
You have a larger array, up to 5000 W across four trackers, and want a reserve of about 5 kWh with 2500 W available if the grid drops. In exchange the unit weighs 50 kg and takes more space, and feed-in is still capped at 800 VA, as on the other one.
