Battery Storage FAQs

Your Battery Storage Questions Answered

Learn about battery sizes, smart tariffs, backup power, and warranties.

During daytime hours, your solar panels generate electricity. Any power not immediately used by your household is routed to charge the battery. When the sun goes down or grid electricity tariffs peak, your home draws power from the battery rather than expensive grid electricity.
No! While batteries work exceptionally well with solar panels, you can also install a standalone battery to charge cheaply from the grid overnight using off-peak tariffs (e.g. Octopus Agile or Economy 7) and discharge that stored power during peak hours.
Yes, absolutely. We can retrofit AC-coupled battery storage to virtually any existing solar array without altering your current Feed-in Tariff (FiT) payments or solar inverter.
Yes. By increasing solar self-consumption from roughly 30-40% up to 80-90%, and utilising cheap overnight electricity tariffs to charge in winter, households typically save hundreds of pounds each year.
Modern lithium iron phosphate (LiFePO4) solar batteries last 10 to 15+ years and come with 10-year manufacturer warranties guaranteeing at least 6,000 to 10,000 charge cycles.
Yes, if configured with an Emergency Power Supply (EPS) backup circuit, your battery can keep essential home circuits (lighting, fridge, WiFi, sockets) running during a grid outage.
Most UK homes install between 5kWh and 15kWh depending on daily evening energy consumption. Our engineers analyse your smart meter data to recommend the optimal battery size.
We install leading Tier-1 UK-approved battery systems including GivEnergy, Tesla Powerwall, Fox ESS, Enphase, and Solax, all backed by 10-year warranties and local UK support.
