Specifications
Last checked on 11 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 (5,000 Wh) in the main unit. The BP5000 expansion battery adds 5,000 Wh. |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Not stated |
| 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. | 10,000 cycles, with a lifespan of 15 years |
| ExpansionExtra battery units that add storage to the same system. | Up to five expansion batteries, 5 to 30 kWh in total |
| Power | |
| AC output, grid-connectedThe lower output allowed when it feeds power into the home's circuits or the grid. | 2,500 W maximum on-grid output |
| Backup outputA separate socket that keeps selected devices running when the grid is down. | Built-in 2,500 W off-grid port for essential devices. The maximum off-grid bypass output is 2,990 W. |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | Under 10 ms, with up to 2,500 W for loads on the off-grid port |
| AC charging inputHow fast it charges from a wall socket or the grid. | 2,500 W fast recharge. Anker says the 5 kWh battery charges fully in under 2 hours. |
| Solar | |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 5,000 W maximum MPPT capability, up to 12 panels |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Grid-connected through a dedicated circuit with an AC supply cable and hardwiring terminals. Anker says it works with third-party solar systems and charges them at up to 2,500 W. |
| Connection and housing | |
| Dimensions (W × D × H)Check the space before you buy, including room around it for airflow and cables. | Not stated |
| WeightMatters for lifting, wall mounting and moving it. | Not stated |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP66 |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | -20 to 55 °C |
| ConnectivityHow you monitor and control it, usually through an app. | Anker app with AI energy management and the Anka voice assistant. Anker says data is processed locally. |
| CertificationsSafety and grid standards the maker says the product meets. | G98 certified and listed, according to Anker |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 10 years |
Compatible with
What Anker SOLIX says this product works with. Anything not listed here is not confirmed.
- Smart meters
- Anker lists the Anker SOLIX Smart Meter (A17X7), the Smart Meter Gen 2, Shelly 3EM and Shelly Pro 3EM (single-phase). Without a smart meter only Custom Mode works and zero-export is not supported.
- Third-party solar systems
- Anker says it can store surplus from a third-party solar system at up to 2,500 W. A smart meter with CTs is recommended.
- Time-of-use tariffs
- Anker says time-of-use mode works with any supplier that offers such a tariff and lists compatibility with Octopus and over 870 suppliers.
Rules where you live
Anker says the hardware supports plug-in use and includes an AC supply cable, but for Great Britain it states that installation must be carried out by a Part P-registered electrician on a dedicated hardwired circuit, with hardwiring terminals supplied as standard. Anker says it will assess plug-in installation if rules and BSI product standards change.
In Great Britain, plug-in solar kits of up to 800 VA have been legal since 27 August 2026, but the rules exclude plug-in batteries.

Where this information comes from
We have not tested the Solarbank 4 E5000 Pro. Every figure above comes from Anker SOLIX's product page, including its FAQ and disclaimers, last checked on 11 November 2026. The page gives no weight, dimensions or battery chemistry, so those are shown as not stated.
We do not show prices, because they change often and differ between sellers. We also leave out Anker's savings and payback figures, which are theoretical values from Anker's own model.

Common questions about Anker SOLIX Solarbank 4 E5000 Pro
Can I plug the Anker SOLIX Solarbank 4 E5000 Pro into a normal socket?
Anker says no in Great Britain: installation must be done by a Part P-registered electrician on a dedicated hardwired circuit. The hardware supports plug-in use and Anker says it will review this if the rules change.
Does the Solarbank 4 E5000 Pro work during a power cut?
Yes. Anker says it switches to off-grid mode within 10 ms and supplies up to 2,500 W to loads on its dedicated off-grid port.
Do I need a smart meter?
Not strictly. Without one only Custom Mode is available and zero-export is not supported. Anker lists its own smart meters and Shelly 3EM models as compatible.
