Anker SOLIX Solarbank Max AC vs E3/DC S10 X

Technical comparison · All-in-one

In brief

Two all-in-one home batteries that differ first of all in the grid they connect to: the Solarbank Max AC is single-phase, the S10 X is three-phase. After that come room to grow and where each can be placed (manufacturer-declared values).

The differences that matter

  • Single-phase with UPS backup switching in 10 ms against three-phase with EPS backup and a brief pause → one phase without a gap, or three phases with a short interruption.
  • Maximum charge power 3.5 kW against 11 kW → for the same energy, in a few hours of cheap tariff the second fills much faster.
  • Maximum expanded capacity 42 kWh against 20.6 kWh → how far the system can grow later.
  • IP66 and −20 to 55 °C against IP20 and 5 to 35 °C → the first can stand somewhere exposed, the second only indoors and frost-free.

Which one to choose

Choose Anker SOLIX Solarbank Max AC if…

the house is single-phase and you want storage that grows in modules over time. It weighs 73 kg, stands on the floor and has 10000 declared cycles. The trade-off: one phase, in backup mode too, and a much lower continuous output than the S10 X, so a three-phase house is not covered on every phase.

Choose E3/DC S10 X if…

the house is three-phase and you want 17.4 kWh usable from day one, with a heat pump that talks to the battery, local control over Modbus and full operation without internet. The trade-off: 155 kg to position in an indoor room, and a lower growth ceiling than the other.
