Anker SOLIX Solarbank 4 E5000 Pro

The grid-connected power generation and solar self-consumption features of Solarbank 4 E5000 Pro are not bound to any specific electricity supplier. The device can seamlessly connect to any Distribution Network Operator (DNO) in the UK for normal use.

The mention of "compatible with Octopus" specifically refers to the device's smart cost-saving feature for TOU tariffs, which automatically charges the battery during low-rate off-peak periods and prioritises discharging during high-rate peak periods to maximise your electricity savings.

This feature is not limited to Octopus. It is widely compatible with over 870 UK electricity suppliers, including British Gas, E.ON Next, OVO Energy, EDF Energy, and ScottishPower. As long as your supplier offers a TOU tariff, the device will fully support it.

In the UK, Anker SOLIX Solarbank 4 E5000 Pro is compatible with Anker SOLIX Smart Meter (A17X7) and Anker SOLIX Smart Meter Gen 2.

Anker SOLIX Solarbank 4 E5000 Pro can be used without a smart meter. However, in this configuration, household load monitoring is unavailable, and advanced energy management features are restricted. Only Custom Mode is available for charge and discharge control, and the anti-backflow (zero-export) functionality is not supported.

When used with a smart meter, the system can access household load data and enable advanced energy management modes, including Smart Mode, Self-Consumption Mode, Time-of-Use (TOU) Mode, and Dynamic Tariff Mode, to maximise energy savings. Anti-backflow functionality is also supported.

The new generation Smart Meter features the following key upgrades:

1. Dual-Measurement Design: Compatible with both new solar and storage installations, and existing PV retrofits, enabling seamless integration of third-party PV systems into a unified energy management system.

2. Active Branch Circuit Protection: Protects the dedicated circuit connected to your Anker devices. It automatically reduces output power when approaching the safety threshold set in the app, proactively preventing overcurrent risks and ensuring safe operation of your home's electrical circuits.

3. Tool-Free Installation: Both the voltage sampling and RS485 ports feature SNAP IN terminals for quick, tool-free wiring.

4. Home Assistant Integration: Fully supports integration with the Home Assistant smart home platform.

5. Auto-Correction for CT Polarity Reversal and Phase Mismatch: Coming soon for Smart Meter Gen 2 (Three-Phase).

Once Anker SOLIX Smart Meter Gen 2 is installed, the Anker app displays:

1. Real-time power usage data, including power, voltage, and current.

2. Daily power usage data, including 24-hour power curves, total grid import energy, and total grid export energy.

3. Historical power usage data, including daily, weekly, monthly, and yearly energy consumption.

All data is viewable as total data or per-phase values.

Under Part P of the UK Building Regulations 2010, Anker SOLIX Solarbank 4 E5000 Pro must currently be installed by a Part P-registered electrician using a dedicated hardwired circuit.

To ensure electrical safety, the hardwired installation and the entire process must comply with applicable UK electrical regulations and safety standards. Although the device is designed at the hardware level to support plug-in connections, this method is not currently permitted. Anker will provide official installation guidance for the plug-in feature as soon as UK regulations officially allow plug-and-play solar systems to be connected via standard sockets.

You can find a qualified, certified electrician through the following official databases — enter your postcode and filter for the "Battery Storage" category. We recommend cross-checking at least two of these databases: MCS (https://mcscertified.com/find-an-installer/), NAPIT (https://www.napit.org.uk/consumer-advice/), NICEIC (https://niceic.com/find-a-tradesperson/). You may also check reviews on Which? Trusted Traders or Checkatrade as additional reference.

Grid registration (G98) is required within 28 days after installation; your electrician can submit this registration on your behalf via ENA Connect Direct.

Yes. Anker SOLIX Smart Meter Gen 2 features a dual‑measurement‑point design, supporting both new PV‑plus‑storage installations and retrofit scenarios with existing photovoltaic systems.

CT (GRID) monitors the household main circuit, while CT (PV) monitors the existing rooftop PV circuit. This allows a single meter to manage both newly installed energy storage systems and existing PV systems within a single energy management platform.

Note: To monitor an existing PV system, an additional CT cable set must be purchased separately from the official website.

It uses standard DIN35 rail mounting, compatible with most distribution boxes. It snaps into place without special tools, enabling fast and easy installation.

Yes. Anker SOLIX Smart Meter Gen 2 features built-in anti-backflow functionality. The meter uses dual current transformers (CTs) to monitor the direction of power flow on both the grid supply circuit (GRID) and the photovoltaic / energy storage system (PV / ESS) circuit.

Once backflow is detected, the meter transmits a command to the connected Anker SOLIX PV / ESS devices via Wi-Fi or RS485 within 3 seconds. The devices automatically adjust their output to keep feed-in power below the set threshold, with no manual intervention required.

Smart Mode integrates three major data sources: historical power generation and consumption data, real-time weather forecasts, and dynamic electricity pricing. Using AI algorithms, it accurately predicts solar generation, household energy demand, and electricity price fluctuations over a 24-hour horizon to automatically generate an optimised charge and discharge schedule.

1. For Fixed-Rate Tariffs
During periods of surplus solar generation or negative electricity prices, Smart Mode can automatically turn on controllable loads (via the Smart Load Port) to maximise solar self-consumption and take full advantage of negative pricing.

2. For TOU (Time-of-Use) or Dynamic Tariffs
In addition to utilising surplus solar generation and negative electricity prices, if solar generation is insufficient, Smart Mode can charge the battery during low-rate off-peak periods and discharge it during peak high-rate peak periods to reduce your electricity costs. Furthermore, if you are enrolled in a grid-export (feed-in) plan, Smart Mode supports exporting stored energy to the grid during the most profitable periods, helping you maximise your revenue.

When connected to Solarbank 4 E5000 Pro, solar panels can be installed in various locations, such as balcony railings, terraces, gardens, or pitched roofs, with compatible mounting brackets.

For a safe and secure installation, we recommend using the manufacturer-provided brackets and fixing methods designed for your specific solar panels to prevent them from falling.

If you intend to mount the panels on an external wall or roof, we recommend consulting your local planning authority beforehand to check whether any permissions are required. We also do not recommend installing the panels indoors near windows, as routing cables inside may pose a safety risk.

Yes. Solarbank 4 E5000 Pro is fully compatible with third-party solar systems. It can intelligently detect surplus solar generation and quickly store it in the battery at a maximum charging power of 2,500W.

App Setup
During the initial setup or daily use, simply go to the "System Configuration" page in the Anker App and check the option "A third-party PV system has been installed in my home."

PV Generation Monitoring and Hardware Configuration Recommendations
For more precise PV generation monitoring and surplus energy management, we strongly recommend pairing it with Anker Smart Meter and current transformers (PV / ESS CTs). The specific hardware configuration depends on your household's grid type:

- Single-Phase Households (with Single-Phase Smart Meter): The single-phase smart meter comes standard with two independent CTs. You can use one to monitor the incoming grid power, and the other to monitor the circuit where the third-party solar system is connected.

- Three-Phase Households (with Three-Phase Smart Meter): The three-phase smart meter comes standard with a 3-in-1 CT bundle designed exclusively for monitoring the grid supply phases. It does not include dedicated CTs for monitoring third-party solar generation. To accurately monitor your third-party PV generation data, you will need to purchase additional sub-circuit CTs separately.

Yes. Mixing panels of different specifications is permitted, but a clear distinction must be drawn between "mixing across different ports" and "mixing on the same port." Provided the input voltage does not exceed the limit, please follow these guidelines:

1. Across Different PV Input Ports: Allowed
Solarbank 4 E5000 Pro features 4 independent PV input ports. You can connect solar panels with different specifications, such as power, voltage, or current, to separate PV ports. Each port operates independently, so panels connected to different ports will not affect one another.

2. On the Same PV Input Port (Parallel Connection): Strictly Prohibited
Do not connect solar panels with differing specifications in parallel to the same PV input port. Mismatched parameters will cause reverse current to flow into the lower-rated panels, resulting in reduced energy yield and potential safety hazards.

Configuration Requirements by Panel Count
4 Panels (One Panel per Port): Connect 1 panel directly to each port. Differing specifications across ports have no adverse effect on system performance.

8 Panels (Two Panels per Port, Parallel Connection): The two panels connected to the same PV input port must have identical specifications.

12 Panels (Three Panels per Port, Parallel Connection): The three panels connected to the same PV input port must have identical specifications.

The normal operating temperature range for Solarbank 4 E5000 Pro is -20°C to 55°C. When the device detects an abnormal temperature, the system automatically triggers a temperature protection mechanism. Safety under abnormal temperature conditions is maintained through the following 7-layer electrical protection system:

1. Cell Safety: Ceramic-coated separators within each cell prevent internal short circuits at elevated temperatures.

2. Thermal Isolation: Aerogel insulation pads are placed between cells to prevent thermal runaway propagation.

3. Electrical Safety: In the event of an overcurrent or short circuit, the system automatically isolates the circuit to prevent circuit burnout and battery pack fires.

4. System Safety: Multi-fault monitoring prevents issues such as overcharging and overdischarging, whilst AI algorithms proactively identify anomalies and issue early warnings.

5. Hazard Isolation Safety: An anti-thermal runaway design ensures no open flames and prevents propagation between battery packs. Conformal coating on circuit boards prevents condensation and avoids short circuits caused by potential electrolyte leakage during thermal runaway.

6. Emergency Pressure Relief Safety: In the event of cell thermal runaway, oxygen is rapidly discharged to prevent combustion. Once discharging is complete, the pressure relief valve closes automatically to prevent oxygen from re-entering and causing reignition.

7. Structural Safety: The device features an IP66-rated waterproof enclosure. Additionally, the base of the battery pack incorporates an anti-corrosion design to ensure that any potential electrolyte leakage does not cause corrosion of the battery assembly.

For optimal and safe operation, install the system in a well-ventilated location where the ambient temperature remains within the permissible operating range of -20°C to 55°C.

Yes. Solarbank 4 E5000 Pro has successfully completed G98 certification and is officially listed.

Generally, you do not need to handle this yourself. Your electrician will submit the notification on your behalf.
