About Crystal® Battery Storage
Save Money by Charging During Off-Peak Hours
Our battery storage systems are designed to help you make the most of off-peak, low-cost energy. By charging your batteries overnight—when electricity is often at its cheapest—you’ll save considerably compared to using electricity at peak hours during the day. The energy stored can then be used throughout the day, effectively “locking in” lower rates and protecting you from higher daytime tariffs. This can lead to substantial savings over time, especially as electricity prices remain unpredictable.
Reduce Your Carbon Footprint by Easing Peak Demand
When you use stored energy instead of tapping into the grid during peak times, you’re not only saving money—you’re also helping to reduce the strain on the UK’s energy infrastructure. Currently, when demand spikes, the grid relies on emergency gas power stations to fill the gap. These stations are costly to operate and significantly increase CO₂ emissions. By reducing your dependency on the grid during peak hours, you’re helping to lower the need for these backup stations, directly contributing to a cleaner, greener UK.
Supporting a Stable, Sustainable Grid for Everyone
Battery storage systems play a crucial role in stabilising energy demand. The UK’s grid is under constant pressure, with demand imbalances caused by fluctuating usage. By shifting your energy use to non-peak times, you’re helping reduce this imbalance, which ultimately leads to a more sustainable energy future. Not only does this promote greater stability for everyone, but it also helps create a stronger foundation for renewable energy sources like wind and solar, which depend on grid stability to function optimally.

What could a battery add?
Set your annual electricity bill, panels and battery size. Switch the battery off to compare with solar panels alone.
You can stack up to roughly 41.94 kWh to 54 kWh of battery capacity on a residential Fox ESS system.
Your battery tops up overnight at around 7p per kWh, ready to use in the day instead of full-price electricity. The 7p rate is for illustration only: your actual off-peak rate is set by your energy supplier.
Indicative only and not a quote. Our experts give a personalised estimate from your roof, shading and usage. These figures are not a promise of savings: actual savings depend on your roof, shading, how you use energy and future energy prices, and are not guaranteed.
Assumes 435W panels producing 850 kWh a year per kW, electricity at 25p and export at 15p per kWh, and 35% of generation used as it's made. With a smart tariff, the battery is also charged overnight at 7p per kWh. That rate is for illustration only: your actual off-peak rate and hours are set by your energy supplier.
