Charge Your Batteries Off-Peak. Use Lower-Cost Energy Through the Day.
A FOX AC charge system lets you store electricity from the grid during lower-cost off-peak periods and use it later when standard or peak rates are higher. No solar panels are required, and the system can be sized around the way your home, business or community building uses electricity.
- No solar panels required
- Flexible storage from 11.5kWh to approximately 46kWh
- Systems designed around your property and electricity usage
- Package prices from £5,995
A Smarter Way to Buy and Use Grid Electricity
Many time-of-use electricity tariffs provide a lower rate during selected overnight or off-peak hours. An AC charge unit allows you to make better use of those periods by charging a battery directly from the grid, ready for the energy to be used later in the day.
When your property needs electricity, the inverter releases energy from the battery to help meet that demand. This reduces the amount of electricity you need to buy from the grid during more expensive periods. Charging and discharging can be scheduled around your chosen tariff and normal usage pattern, making the system simple to live with day to day.
Because the solution works without solar panels, it is ideal for properties where roof-mounted solar is not practical, permitted or preferred. It can also offer a lower upfront cost than a complete solar and battery installation while still giving you greater control over when you buy electricity.
Why Choose an AC Charge Battery System?
Make the Most of Off-Peak Rates
Store electricity during lower-cost tariff periods and use it later when grid rates are higher.
No Solar Panels Needed
There is no requirement for a suitable roof, scaffolding or rooftop panels. The batteries charge directly from the electricity grid.
A System Sized Around You
Choose from one to four FOX EP12 batteries, allowing the storage capacity to be matched to smaller homes, high-usage households and larger properties.
Lower Initial Investment
Without the cost of solar panels and roof installation, a battery-only solution can be more affordable than a complete solar and battery system.
Automatic Everyday Operation
Once configured, the system can follow its charging and discharging schedule automatically, helping you use stored power without changing your normal routine.
Suitable for Homes and Larger Buildings
The same principle can be scaled for domestic properties, businesses, churches, community buildings and other sites with significant daytime electricity demand.
Work Process
How the System Works
We Review Your Electricity Usage
We look at your bills, tariff and typical consumption to understand how much energy you use and when you use it.
Your System Is Sized Correctly
We recommend the right combination of FOX AC charger inverter and EP12 batteries for your property, rather than oversizing or undersizing the system.
The Batteries Charge Off-Peak
The inverter draws electricity from the grid during the charging period set around your tariff and stores that energy in the batteries.
Stored Energy Powers the Property
During the day or at higher-rate times, the system supplies energy from the batteries. The grid remains available whenever additional electricity is needed.
Flexible Battery Storage to Suit Your Usage
Each system combines a 5kW FOX AC charger inverter with between one and four FOX EP12 batteries. Every EP12 provides approximately 11.5kWh of storage, allowing the complete system to be tailored from 11.5kWh up to approximately 46kWh.
| FOX EP12 Batteries | Approx. Storage | Indicative Application |
|---|---|---|
| 1 battery | 11.5kWh | Smaller or medium-sized homes with moderate electricity use |
| 2 batteries | 23kWh | Larger households or properties with higher daytime and evening demand |
| 3 batteries | 34.5kWh | High-usage homes, small businesses or community buildings |
| 4 batteries | 46kWh | Larger users and properties with sustained daytime electricity demand |
These examples are a guide. Your recommended battery capacity will be based on your actual usage, tariff, electrical supply and the available charging window.
Example Package Pricing
A clear starting point for customers who want battery storage without the cost of installing solar panels.
| Package | System Includes | Price |
|---|---|---|
| 11.5kWh package | 5kW FOX AC inverter plus 1 FOX EP12 11.5kWh battery | £5,995 |
| 23kWh package | 5kW FOX AC inverter plus 2 FOX EP12 11.5kWh batteries | £7,995 |
| Larger systems | 5kW FOX AC inverter plus 3 or 4 FOX EP12 batteries | Tailored quote |
Every installation is subject to a technical survey. The final system design and quotation will reflect the property, electrical requirements and selected battery capacity.
Who Is This Solution For?
An AC charge battery system may be the right fit if:
- You want to benefit from an off-peak or time-of-use electricity tariff.
- You do not have solar panels and do not want or cannot install them.
- Your roof is unsuitable, heavily shaded or subject to planning or heritage restrictions.
- You use a significant amount of electricity during daytime or higher-rate periods.
