- Best for modular hybrid storage
- Installed system
- 5-30 kWh
- 10-year warranty
- Energy: 5 kWh per battery module, up to six modules (30 kWh) on one single-phase power module.
- A hybrid system: the power module is the inverter, with two solar inputs (up to 12 kW of panels).

Specifications
Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 5 kWh per battery module (100 Ah rated), from 5 kWh with one module to 30 kWh with six on a single-phase power module |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | Not stated in the sources we read |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP (lithium iron phosphate) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | Not stated in the sources we read |
| ExpansionExtra battery units that add storage to the same system. | Up to six battery modules per power module (no more than four stacked per column); several systems can be run in parallel on the grid side, though the page gives different limits in different tables |
| Power | |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | Battery module: 3 kW maximum (7.6 A). Power module AC output 3.68, 4.6, 5 or 6 kW; peak 4.5 kW for 10 seconds with one battery module and 9 kW for 10 seconds with two |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | Not stated in the sources we read |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Off-grid mode with switchover in under 10 ms; Anker does not name an EPS output rating on the page |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | Built into the power module: two MPPT inputs with one string each, 80-550 VDC range, up to 600 VDC, 16 A per input, maximum PV power 7.36, 9.2, 10 or 12 kW depending on the module |
| Connection and housing | |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Single-phase, 220/230/240 V, 50/60 Hz (three-phase power modules also exist) |
| Dimensions (W × H × D)Width, height and depth of the unit, so you can check that it fits. | Battery module 670 × 360 × 150 mm; power module and battery configuration shown on the page 670 × 335 × 150 mm |
| WeightMatters for lifting, wall mounting and moving it. | Battery module 51 kg; the page lists 19 kg for the power-module configuration it shows |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP66 (C5-M corrosion protection listed on the product page) |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Battery module -20 to 55 °C. The product page also gives -25 to 60 °C in one table, so check the installer guide |
| ConnectivityHow you monitor and control it, usually through an app. | Anker app; works with Anker SOLIX EV Charger, Power Dock Pro, Solarbank and Anker microinverters, and dynamic-tariff providers via API |
| CertificationsSafety and grid standards the maker says the product meets. | The battery module guide cites UK PSTI Regulations 2023 and EU directives 2023/1542, 2014/30/EU and 2011/65/EU. No cell or battery safety standard (such as IEC 62619) was listed in what we read |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 10 years |

Where this information comes from
We have not tested the X1. Every figure above comes from Anker SOLIX's UK X1 product page and the Anker user guide for the X1-B5-H battery module, last checked on 10 November 2026. A value that these sources do not state is shown as not stated.
We do not show prices, because they depend on the installer's quote.

Common questions about Anker SOLIX X1
How much can the Anker SOLIX X1 store?
Each battery module is 5 kWh. Anker lists up to six modules on one single-phase power module, which is 30 kWh. Anker does not state a usable capacity.
Does the X1 include an inverter?
Yes. The power module contains the inverter and two solar inputs, so it works as a hybrid system. AC output options are 3.68, 4.6, 5 and 6 kW.
Does the X1 work in a power cut?
Anker describes an off-grid mode with a switchover time under 10 ms, but does not give a backup output rating on the page. Ask your installer how the backup circuit is wired.
