Key Features of Battery Storage with Grid Integration:

  • Export Surplus Energy:

    Sell excess stored energy back to the grid during high-demand
    periods.

  • Octopus Flux Compatible:

    Benefit from one of the best smart export tariffs available.

  • Energy Bill Savings:

    Offset rising electricity costs through greater self-consumption.

  • Peak-Time Profits:

    Export when prices are highest — typically in the early evening.

  • Grid Charging:

    Charge your battery from the grid during off-peak times (if needed).

  • No Solar? No Problem:

    Battery-only systems can still buy low and sell high with the right
    tariff.

Boost Your Solar Self-Consumption with Battery Storage

By installing battery storage alongside your Solar PV system, you can significantly
increase your self-consumption of solar energy—from around 30–40% up to
70–80%. This means greater savings on your energy bills and a shorter payback
period for your solar investment.

Battery storage is especially valuable if you're away from home during the
day—when solar generation is at its peak. Instead of exporting excess energy back
to the grid, a battery allows you to store that energy for use later, such as in the
evening when your energy use typically increases. This way, you're using more of
your own renewable energy and relying less on your energy supplier.

Turn Your Battery Storage into an Income Stream

Sell Excess Energy Back to the Grid with Solar PV &Battery Storage

With a Solar PV and Battery Storage system installed, you can do more than just
reduce your energy bills — you can also sell excess energy back to the grid, turning
your system into a potential revenue generator.

While self-consumption remains the most cost-effective way to use your solar
energy, any surplus stored in your battery can be exported during peak demand
periods, when export rates are at their highest — such as between 4pm and 7pm.

By taking advantage of smart export tariffs like Octopus Flux, you can maximise the
financial return from your system. Octopus Flux is designed specifically for homes
with both solar and battery storage, offering higher export rates during peak times.

Standalone Battery Storage — No Solar Needed

Backup Power & Energy Flexibility Without Solar Panels

You don’t need solar panels to benefit from a battery storage system. Standalone battery
setups allow you to take control of your energy use, reduce your reliance on the grid, and
provide emergency backup power during outages — all without installing Solar PV.

Backup Power for Peace of Mind

Beyond energy savings, battery storage offers the crucial benefit of keeping the lights on
when the grid goes down. Whether you're at home or running a business, systems can be
configured to back up your entire property or just essential circuits, including:

  • Lighting
  • Heating controls
  • Security systems (intruder alarms, CCTV)
  • Smoke and fire alarms
  • Low-load socket circuits

Smart Energy Usage — With or Without Solar
Standalone batteries can also be paired with smart tariffs like Octopus Flux, allowing you to:

  • Charge your battery during off-peak hours when electricity is cheaper
  • Discharge and export energy back to the grid during peak times, when rates are higher

This means you can buy low and sell high, even without generating solar power — making
battery storage a smart, flexible solution for homes and businesses alike.

What people say about us

Frequently asked questions

Please find some questions we’ve answered.

Should you have any further questions, we will be happy to answer them.

How many batteries would I need?

The number of batteries needed is dependent on your specific load profile. Bigger is not always better!

We carry out site specific load profiling, which will give us an idea of your peak usage including how much energy you’re using and at what times. We do this by typically looking at your last 3 months electricity bills.

More often than not, we recommend that you install a smaller battery system initially, and then if you find that you could do with extra storage, we can expand the system at a later stage.

All our battery storage systems are modular, so you can add additional batteries with minimal fuss.

Are there any grants available?

Unfortunately, there isn’t any grants available for Battery storage alone, but the UK government announced they have reduced the VAT threshold for standalone Battery storage systems down to the same level as Solar PV which is 0% VAT.

Do I need Solar Panels to install Battery storage?

No you don’t need Solar Panels to enjoy the benefits from having a Battery storage system, especially when there are now agile energy tariffs from companies like Octopus energy, you can charge up on cheaper electricity overnight at off peak periods and then sell back to the grid for a profit during high demand periods.
