Solarbank 4 E5000 Pro
It's time for a new kind of savings. One that works while you sleep.
800W Grid-Tied Output
2,500W Bidirectional Charging
Peak Production to Meet All Your Energy Needs
Your energy needs won't stay the same, and your system shouldn't either. Solarbank 4 E5000 Pro's 4 MPPTs support 4 to 12 panels, generating up to 5,586kWh annually—enough to cover daily consumption, keep an EV charged, and still have plenty to spare.

1.1 The maximum annual savings provided are theoretical values, derived from an internal model comparing a reference household budget for a grid-connected photovoltaic system with that of a household using a Solarbank 4 Pro system.
Daytime: Solar generation is fully consumed by midday or during the evening peak.
Configuration: 1 × 5kWh main unit; 4 × 500W solar panels (total PV power: 2,000W); AC output: 2,500W (off-grid / hardwired); Total cost: £2,510.
Annual Electricity Consumption: 4,100kWh.
Annual Energy Generation: 2,000 × 0.9 = 1,800kWh.
Solar Self-Consumption Energy Savings (Excluding Discharge Impact): 1,800kWh × 0.94 = 1,692kWh.
Solar Self-Consumption Rate: 94% (sourced from HTW Berlin Solar Storage Revenue Calculator).
Solar Self-Consumption Energy Savings (Including AC Discharge Impact): 1,692kWh × 0.92 = 1,557kWh (where 0.92 is the AC discharge impact coefficient).
Predicted Energy Savings from Surplus PV Generation: Surplus energy × 30% = (1,800 - 1,557) × 30% = 72.9kWh (where 30% represents the surplus energy utilisation rate).
Total Annual Self-Consumption Energy Savings: 1,557 + 72.9 = 1,629.9kWh.
Total Self-Consumption Revenue: 1,629.9 × £0.26 = £423.80.
Self-Sufficiency Rate: 1,629.9 ÷ 4,100 = 39.75%.
Self-Consumption Rate: 1,629.9 ÷ 1,800 = 90.54%.
Actual grid-connected PV system output, the number of modules, and energy generation depend on local regulations, grid connection requirements, installation conditions, and usage scenarios. Annual energy generation and electricity cost savings are theoretical calculations; actual results may vary.
Night-Time: Time-of-use (TOU) tariff, charging at off-peak prices at night, and discharging during the morning peak.
TOU Peak / Off-Peak Arbitrage:
Taking a 5 kWh energy storage system as an example, the charging efficiency is 95% and the discharging efficiency is 95%.
Under a traditional time-of-use tariff (taking Octopus Go as an example), off-peak hours are fixed at 12:30 AM - 5:30 AM, priced at £0.085/kWh. The remaining time periods are calculated based on a peak price of £0.2937/kWh.
Since there is only one fixed off-peak window each day, the energy storage system can typically complete just one full charge using cheaper night-time electricity and one full discharge during the day / evening peak period. Therefore, calculating based on one cycle per day is more accurate.
1) Cost per Charge
To fully charge a 5kWh battery, assuming a 95% charging efficiency, the actual energy input required is:
5 ÷ 95% = 5.26kWh
At an off-peak electricity price of £0.085/kWh, the cost per charge is:
5.26 × £0.085 = £0.447
2) Value per Discharge
When discharging a 5kWh battery, assuming a 95% discharging efficiency, the actual usable electricity for the load is:
5 × 95% = 4.75kWh
At a peak electricity price of £0.2937/kWh, the value per discharge is:
4.75 × £0.2937 = £1.395
3) Revenue per Cycle
The revenue per cycle is:
£1.395 - £0.447 = £0.948
4) Daily Revenue
Since there is only one off-peak charging window each day, the calculation assumes one complete cycle per day. The estimated daily revenue is therefore:
£0.948/day
5) Annual Revenue
Based on a 365-day year, the annual revenue is:
£0.948 × 365 = £346.02/year
Total Revenue = TOU + PV Self-Consumption = £346.02 + £423.80 = £769.82.
Payback Period = Total Investment ÷ Total Revenue = £2,510 ÷ £769.82 = 3.26 years.
Note: The UK equivalent generation factor is 0.9, and the average electricity price is £0.26/kWh. The TOU off-peak window is fixed at 12:30 AM - 5:30 AM with an electricity price of £0.085/kWh; the peak electricity price is £0.2937/kWh.
1.2 PV yield is based on standard peak sun hours (e.g., PVGIS data). Actual results may vary significantly depending on location, weather conditions, individual consumption patterns, dynamic electricity rates, battery ageing, and system configuration.
1.3 This information is for illustrative purposes only and provides no guarantees. Unless otherwise stated, taxes, professional installation costs, and local grid connection fees are not included.
2. The payback period is calculated based on the comparison between total system investment cost and estimated annual savings. The above system configuration is expected to achieve payback in approximately 3.3 years.
3.1 "Can power 95% of household electricity needs" is calculated based on the Solarbank 4 Pro system's 2,500W rated output compared to typical UK household electricity demand.
3.2 "95% household electricity" refers to typical daily usage scenarios, including standby loads, lighting, refrigerator, washing machine, dishwasher, TV, computer and other common appliances (typically under 2,500W). High-power devices such as EV chargers (3.7kW+), heat pumps (4kW+) and electric water heaters are excluded, as these require additional grid capacity assessment or dedicated circuits.
4.1 IP66 certification means the device is protected against dust ingress and resistant to high-pressure water jets. However, it is not designed for submersion or underwater use.
4.2 For outdoor use, the device should always be installed according to the operating instructions—ensure adequate ventilation, waterproofing, and elevated installation. Prolonged exposure to standing water, heavy rainfall, or extreme marine or corrosive environments should be avoided. If such conditions exist, additional protective measures are required.
5. Solarbank 4 E5000 Pro is a plug-in solar storage, according to the UK Building Code Part P, its installation is classified as a reportable electrical work due to the inclusion of a battery storage module. To ensure your safety and compliance, installation must be performed by a competent electrician registered under a Part P-approved scheme (e.g., NICEIC or NAPIT), using a dedicated hardwired connection to the distribution board, and paired with Anker SOLIX Smart Meter Gen 2. Hardwired terminals are included to fully meet this compliance requirement. Anker SOLIX is not responsible for problems caused by ageing wiring, improper or non-compliant installation in the user's home.
Solarbank 4 E5000 Pro is designed with plug-and-play-ready hardware, and an AC cable is included in the box. Installation guidance will be provided once the relevant UK regulations and BSI standards governing plug-and-play solar and energy storage systems are in force.
Note: This statement will not affect your legal rights under the Consumer Rights Act 2015.
6. Users are responsible for ensuring system installation complies with local grid connection regulations. Different countries and regions may have varying regulations regarding power limits, registration requirements, and installation standards for balcony solar storage systems.
