Electric11 installed an AC-coupled Fox ESS battery storage system at a residential property in Norwich, combining two EP12 batteries with a 10.5 kW inverter and protected connections to the existing electrical installation. The completed system provides 23.04 kWh of nominal storage, giving the household greater control over when stored electricity is used.

The project required more than mounting batteries to a wall. Electric11 had to assess the existing distribution equipment, plan the cable route, provide suitable local isolation and integrate the storage system with the property’s established electrical arrangement.
Homeowners considering a similar upgrade can explore Electric11’s home battery storage installations in Norwich. A qualified electrician in Norwich can also assess whether the existing consumer unit, earthing, bonding and available capacity are suitable for new energy equipment.
Electric11 installed two Fox ESS EP12 high-voltage batteries, each rated at 11.52 kWh of nominal energy. Together, they provide 23.04 kWh of nominal storage capacity.
Fox’s current EP12 specification lists lithium iron phosphate battery chemistry, a 90% depth of discharge, IP65 protection and support for up to four units in parallel. The two installed units were positioned together beneath the inverter, creating a compact wall-mounted arrangement with accessible connections and isolation equipment.
The system can store suitable lower-cost grid electricity or surplus solar energy for later household use, depending on its final operating mode and the energy sources connected to the property. Customers planning to combine storage with generation can also review Electric11’s solar panel installation service in Norwich.
The latest job record specifies a 10.5 kW Fox ESS inverter and describes the equipment as a hybrid inverter. The supplied photographs confirm Fox-branded inverter equipment, but the model label is not readable enough to distinguish the exact KH or KA variant. The final model should therefore be checked against the commissioning record before publication.
The inverter controls charging and discharging between the batteries, household electrical system and grid connection. A Fox ESS high-voltage junction box links the paired batteries into the wider storage arrangement, while the local isolator provides a clear means of disconnection for safe maintenance and emergency isolation.
Electric11 also installs home battery storage systems across Norfolk for new renewable-energy projects, compatible retrofits and future capacity upgrades.
The system was connected to the property’s existing main switchboard through new cabling and dedicated protective equipment. Project photographs document the original distribution arrangement, additional enclosures, the labelled battery circuit and the completed equipment connections.
Later photographs also show an existing Pod Point EV charger beside the local protective equipment. The supplied job scope does not state that Electric11 installed or modified this charger, so it should be described only as existing equipment visible at the property unless additional records confirm EV charging work.
The Norwich property gained a high-capacity Fox ESS battery storage system with two matched EP12 units, inverter control, protected switchboard integration and neatly contained cabling. The 23.04 kWh nominal capacity gives the household substantial flexibility to shift suitable electricity into later periods of demand.
The installation also provides a platform for future energy planning. Depending on the final configuration, the system can support greater solar self-consumption, time-of-use tariff management and coordinated household charging demand.

Home battery installations depend on accurate system sizing, electrical compatibility and careful coordination with the property’s existing equipment. Electric11 follows a structured process designed to deliver safe integration, clear communication and a system configured around the customer’s energy goals.
Energy and Electrical Assessment
The team reviews the household’s energy use, existing solar or charging equipment, consumer unit, electrical capacity and proposed battery location. Suitable cable routes, access restrictions, earthing and isolation requirements are identified before the system design is finalised.
System Design and Clear Quote
Electric11 prepares a system design and transparent quotation covering the batteries, inverter, protective devices, cabling, commissioning and any required electrical upgrades. Battery capacity, operating options and future expansion requirements are explained before work begins.
Coordinated Battery Installation
The batteries, inverter, high-voltage junction box, isolation equipment and containment are installed in the agreed positions. For this Norwich project, two wall-mounted EP12 units were integrated with the existing main switchboard through protected electrical connections.
Testing, Commissioning and Handover
The completed system is electrically tested, configured and commissioned for its intended operating strategy. Applicable notifications and certification are completed, and the customer is provided with the relevant system and operating information during handover.
Electric11 installed two Fox ESS EP12 batteries rated at 11.52 kWh each. Together, they provide 23.04 kWh of nominal storage capacity.
An AC-coupled battery system connects to the property’s AC electrical installation. The inverter converts electricity as required to charge and discharge the batteries while coordinating with the household supply and grid connection.
An appropriately configured battery can charge from the grid during suitable lower-cost periods and discharge later. The financial and carbon benefits depend on the tariff, charging source, system efficiency and programmed operating schedule.
The inverter manages electricity moving between the batteries, household electrical installation and grid. Depending on the confirmed model and final configuration, it may also coordinate compatible solar generation.
The Pod Point charger is visible in the supplied project photographs, but EV charger work is not included in the confirmed job scope. It should be treated as existing equipment unless additional project records confirm otherwise.
The job record states that electrical certification and required notifications will be provided. Confirm the exact UK certificate type against the completed project documentation before publishing the page.
