FOX ESS Home Battery Storage Installation in Norwich

Electric11 installed a 23.04 kWh Fox ESS battery storage system at a residential property in Norwich. Two 11.52 kWh EP12 Plus batteries were connected to a Fox hybrid inverter and integrated with the home’s consumer unit through protected cabling and local isolation. The system gives the household greater control over surplus solar power and lower-cost off-peak electricity.

Home energy demand rarely follows the same pattern as electricity generation or lower-cost tariff periods. A household may have its highest usage in the morning and evening, while surplus solar generation or cheaper grid electricity is available at different times.

Battery storage helps close that gap. Electricity can be stored when it is available and released later when the home needs it, subject to the system’s operating mode and charge settings. Electric11 designed the installation around the property’s electrical layout, equipment location and connection route to the main house.

Electric11 installed two FOX ESS EP12 Plus high-voltage battery units. The equipment labels confirm a nominal energy rating of 11.52 kWh per battery, giving the property 23.04 kWh of combined nominal storage.

The EP12 Plus uses lithium iron phosphate battery chemistry and carries an IP65 ingress-protection rating. Its label also records a nominal voltage of 384 V and a maximum charge and discharge current of 30 A. These specifications help define how the batteries must be matched, connected and configured with compatible equipment.

The two units were positioned together on a brick wall beneath the hybrid inverter. Grouping the related equipment in one area created a compact installation while retaining access to the battery isolators, communication links and cable connections.

The hybrid inverter manages the movement of electricity between the battery system, household loads and grid connection. Depending on the wider system configuration, it may also coordinate electricity generated by solar panels.

The job notes refer to an 8 kW hybrid inverter, while the photographs confirm FOX-branded equipment but do not show a readable model label. The exact inverter model and rated output should therefore be checked against the commissioning records before the page is published.

Keeping the inverter and batteries within the FOX ESS ecosystem supports compatible communication and coordinated control. The installation also includes a FOX ESS high-voltage junction box, with its equipment label showing a 500 VDC rating, 50 A maximum input and output current, and IP65 protection.

Electric11 also provides home battery storage services across Norfolk for new installations, compatible retrofits and system-capacity upgrades.

The battery system had to be incorporated into the property’s wider electrical installation. Project photographs show a Hager consumer unit with individual protective devices, a 100 A main switch, labelled circuits, earthing conductors and organised neutral connections.

Appropriate protection and clear circuit organisation are important when adding new energy equipment to a home. The available electrical capacity, protective devices, cable routes and earthing arrangements must all be reviewed as part of the design and commissioning process.

Properties that need broader distribution upgrades can also explore Electric11’s consumer-unit replacement service in Norwich. A qualified electrician in Norwich can assess the existing installation before recommending battery storage or other higher-demand equipment.

Additional cabling connected the battery equipment with the main house. The supplied project information refers to armoured Cat 6 cable runs, but the exact cable count and final specification should be confirmed before publication.

The exterior photographs show neatly routed black cabling fixed along the garden wall and returning towards the house. Planning this route helped keep the connection contained while working around the property’s outdoor layout and established structures.

The finished garden photographs also show the external lighting in operation. Its inclusion within Electric11’s confirmed scope should be checked before the page attributes the lighting work to this project.

• Installed two FOX ESS EP12 Plus high-voltage batteries.

• Added 23.04 kWh of combined nominal battery storage.

• Installed and connected a FOX hybrid inverter, subject to final model confirmation.

• Installed the FOX ESS high-voltage junction box and local isolation equipment.

• Integrated the battery system with the property’s electrical distribution arrangement.

• Routed additional cabling between the battery equipment and main house.

• Prepared the electrical work for testing, commissioning and certification.

Battery storage does not create electricity. Its value comes from changing when available electricity is used. The system can retain surplus solar generation for later household demand or charge during suitable lower-cost tariff periods, depending on the final setup.

For the Electric11 case-study template, a working estimate of 7,200 kWh of electricity shifted per year has been applied. This represents approximately 312.5 equivalent full-capacity cycles across the 23.04 kWh battery system.

At an indicative benefit of 18p for each shifted kilowatt-hour, the estimated yearly saving is £1,296. An indicative carbon displacement factor of 0.18 kg per kilowatt-hour gives an estimated annual reduction of 1,296 kg CO₂.

These figures are scenario estimates rather than guaranteed performance claims. Actual outcomes depend on the home’s electricity consumption, tariff difference, charging source, solar availability, usable battery capacity, efficiency losses and programmed charge windows. Carbon savings may be lower if the batteries are charged mainly from the grid rather than surplus renewable generation.

The job information states that Electric11 will issue an Electrical Certificate in line with BS 7671. The final certificate type, testing date and commissioning status should be checked before publication so the case study reflects the completed handover accurately.

The consumer-unit photographs include a Hager earth-bond test label recording a pass result. This supports the visual project record, but it should not be treated as a substitute for the complete Electric11 certification pack.

For broader fixed-wiring inspections, Electric11 also provides EICR certificates in Norwich for homeowners, landlords and businesses.

The Norwich property gained a substantial 23.04 kWh FOX ESS battery storage system with two matched EP12 Plus units, hybrid inverter control and protected electrical integration. The wall-mounted arrangement keeps the core energy equipment together and provides accessible local isolation and connection points.

The installation gives the household more control over when stored electricity supports demand. It also creates a platform for increased solar self-consumption or time-of-use tariff management, depending on the final energy source and operating configuration.
