Technical comparison · All-in-one
These are two single-phase home batteries of similar size built for different places: one is IP66 and works below freezing, the other goes in an indoor technical room. The choice starts with where it will be installed.

The differences that matter
- 10 versus 5 years of warranty → the 10,000 declared cycles are the same, but the warranty is the limit that comes first: with the second you are out of cover after 5 years.
- IP66 and −20 to 55 °C versus IP30 and 5 to 35 °C → this decides where it can go: one handles a garage or outdoors, the other only an indoor room.
- Charge 3.5 versus 2.5 kW → the first absorbs a bigger solar surplus, the second feeds bigger loads.
- 73 kg floor-standing versus 53 kg wall-mounted → one needs a base and a route to carry it in, the other a wall that can take the weight.

Which one to choose
Choose Anker SOLIX Solarbank Max AC if…
you put it on the floor in a garage, an unheated cellar or outdoors, where winter drops below zero. The trade-off: 3,500 W of continuous power, which may not be enough with several big loads on at once.
Choose SAX Power Home 5,8 kWh if…
you have a sheltered technical room with a free wall and want the single-phase home to keep running in full island mode at 4,600 W continuous when the grid is down. The trade-off: IP30 and an operating range of 5 to 35 °C, so no cold garage.
