There are many reasonss why you would install a battery storage system in your home. If you have a PV array already in place, then it is likely that you are exporting up to 55% of that energy back to the grid. This is your energy that you have generated for free – and you get paid for generating that energy regardless of whether you use it or export it. By storing this surplus production for use later in the day you can increase ‘self-consumption’ to in excess of 70%, drastically reducing your reliance on the grid and driving down your energy bills. Adding solar panel battery storage is a logical decision for anybody who is looking to save some money.

Charge from surplus solar

Works with any existing solar pv system on the market

Adding batteries to your existing solar pv system has no bearing on your current feed-in-tariff agreement, you will still get paid on everything that you generate whilst storing your excess energy. Our system also works with any existing inverter on the market today

Charge from cheap energy

Works by itself charging from grid on cheap rate energy

Even better, our storage batteries can be charged directly from the grid, if you have economy 7 or a good time of use tariff you can utilise this window to fill your batteries with cheaper rate electricity and use it when the price is high, doing this can help you save a lot of money on your energy bills

Power cut protection

Our systems have the option for emergency power supply, meaning you will be protected from power cuts.

Smartphone app

Monitor your system from your smartphone, tablet or computer from anywhere in the world

Reduce bills

A battery storage system can dramatically reduce your energy bills.

Price protection

Energy prices are continuing to rise, solar battery systems protect you from any price increases.

FIT unaffected

If you are registered for the FIT, adding batteries will have zero impact on your payments.

Suitable for everyone

Batteries can be installed in any property – with or without solar panels and can be used to store cheap rate energy.

Access cheap rate energy

Charge your batteries up overnight using a cheap rate tariff such as Octopus Go or economy 7.

Common Battery Storage Questions

Probably the most important question if you have solar, the answer is absolutely not! As our systems fit after the generation meter and are standalone to your existing system, your FIT is not effected.

Battery storage systems work by receiving electricity from the power grid or from solar panels during daylight and store it to release it when needed. The battery converts this stored energy from DC into AC power to store and keep it ready to use for later. By storing energy during the daylight, battery storage systems can keep homes running at peak times.

There are many benefits of solar panel battery storage in your home, here’s just a few:

  • Reduce your carbon footprint – Installing batteries allows you to reduce the need for traditional energy sources such as gas or coal and rely on solar panels to produce your energy to be stored in the batteries for use later.
  • Minimise energy bills – With rising cost of living and energy bills still leaving people out of pocket, its important to see the value in adding a battery storage system to your existing solar panels. By adding batteries to your set up you’ll be able to store any excess energy for use during down periods and reduce the cost of your energy bills.
  • Never go without power – Whether sun is hiding or it’s the middle of a power cut, you’ll always have power with a solar panel battery storage system.

You can install your battery storage system almost anywhere! Our systems are IP65 rated and are not adversely effected by cold temperatures like most on the market, meaning they can go outside. AC storage is flexible, we don't need to install it where your current inverter is, our team will talk you through all installation options.

You are expected over >6000 cycles out of our solar panel battery storage systems, meaning if you did one full charge / discharge everyday that would be 17 years at full capacity.

Yes! Solar inverters are used as part of the battery storage system to help convert DC electricity to AC ensuring that your home is powered safely and effectively.

You can learn more about what are solar inverters and how to pick the best one on our blog.


Yes, there are a few options for this. Automatic whole house changeover, powering critical circuits or a simple double socket connection, meaning your house is always switched on with your battery storage system.

Yes, our battery systems are future proof and can be set to be enable to charge the battery’s with energy delivered from the grid at off peak times, and automatically transfer to battery power at peak times, in the event that TOU’s (time of use tariffs) become popular.

All of our solar panel battery systems come with a full 10 year warranty.

We can accommodate any level of battery storage, all of our battery solutions are expandable. We normally work out an ideal capacity for you based on information provided to us such as your energy consumption.
