Case study
Home battery install with Paul
Join us as we install a GivEnergy All-In-One home battery system
Installation day
Paul, based in Halstock, Dorset, was already charging his electric vehicle using a 7p/kWh off-peak tariff (at the time of publishing). After seeing how effective that strategy was, he explored how battery storage could help lower his overall home electricity bills - especially in a rural area prone to storms and regular power cuts.
After careful research, Paul chose Evoflo to install a GivEnergy All-In-One home battery system with a backup gateway. This setup allows him to store cheap, off-peak energy overnight and use it during the day - saving money and ensuring uninterrupted power during outages.
Although solar panels weren’t an option for his property, Paul was reassured that much of the UK’s overnight energy comes from renewable sources like wind. Since the installation, he’s cut his electricity bills by around 70% by discharging stored power during peak hours.
Paul chose Evoflo for our transparent pricing, fast turnaround, and GivEnergy-certified installation - which ensures he benefits from the full 12-year warranty. The system was installed quickly and with minimal disruption. Paul now confidently recommends Evoflo to anyone looking for a reliable, fuel-free energy storage solution for the home.

Your Guide to off-peak charging
What are the benefits?
Big Savings on Your Energy Bills
Make huge savings on your energy bills, by switching to a smart overnight tariff from Octopus, British Gas, Eon or EDF, your home battery charges when prices are lowest. Use that stored energy all day - no solar panels required.
Take Control of Your Energy
Battery storage gives you the freedom to store power from the grid or renewables like solar or rooftop wind. It’s a smarter way to manage your energy, reduce waste and increase self-reliance.
Cleaner, Greener Power
Enjoy 100% renewable energy, mostly from offshore wind. You’ll lower your carbon footprint and reduce your dependence on fossil fuels, all while powering your home efficiently.
No Solar Needed
Our systems work with or without solar. Charge overnight using low-cost grid power, power your home during the day, and even connect your EV charger for maximum savings.

FAQs
How does overnight charging save me money on my energy bills?
Overnight or off-peak charging takes advantage of cheaper electricity rates, typically available between midnight and early morning. By storing this low-cost energy in a home battery, you can power your home or electric vehicle during expensive daytime hours - reducing your bills by up to 70% like Paul our happy customer. This percentage is based on the customer’s actual installation and monitored results. Individual outcomes depend on your energy habits, tariff, and system design.
Can I charge my battery from the grid even if I don’t have solar panels?
Yes - all Evoflo battery systems support grid-only charging. You don’t need solar to benefit. Our systems automatically charge during off-peak hours, giving you access to ultra-cheap electricity (as low as 7p/kWh at the time of publishing) whether the sun shines or not.
What’s the best energy tariff for off-peak battery charging?
We often recommend flexible tariffs like Octopus Energy’s Intelligent Go or Cosy, which offer low overnight rates. We’ll help you pick the right one, and configure your system to automatically charge when electricity is cheapest - maximising savings without lifting a finger.
