Your Guide to off-peak charging
What are the benefits?
Big Savings on Your Energy Bills
Cut your electricity costs by up to £1,500 a year. 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%.
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) 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.
