Energy Storage Systems


Benefits of energy storage systems

Adding an energy storage system minimises your reliance on the grid, and reduces the money you put in your energy supplier’s pocket.

Renewable energy from wind power and solar are the most widely generated, but while these sources of power are clean and renewable, they have one main disadvantage — they are not available 100% of the time. Solar power is only available during the day, whilst wind does not blow continuously. Solar power is, therefore, mostly available when there is less of a need for lighting homes, so it’s vital to store the power so that it can be used when it’s required — and that’s where energy storage systems come into play.

The PureStorage II AC battery system comes in two sizes including, 5kWh and 10kWh and are sized perfectly for homes in the UK. The PureStorage II AC system is an ‘all in one box’ solution, making it more aesthetically pleasing and easy to install.

They can be installed indoors and outdoors and have a wide temperature operating range from -20 to 45C.

The system stores excess PV energy during the day using its LiFePo4 solar battery.  This allows you to increase your utilisation of generated power from 30% to up to 85% powering your home from the battery during the evening and through the night until the sun rises.  Reducing the need to import energy from the grid.

Allows for better use of renewable energy

The use of batteries to store this power is a necessity, ensuring the power can be used whenever you need it. With batteries, your excess power is stored in the battery system, so on those overcast days when your solar system doesn’t produce as much power as you need, you can pull from the batteries, instead of the grid.

Less dependent on the grid

Solar battery systems enable you to build a home that’s far more resilient and less dependent on the grid. For example, if you live in a rural area where the grid is known for being unstable, you gain peace of mind with a battery storage system, knowing you are in a position to power key aspects of your home for many hours.

Reduce your carbon footprint

Installing solar batteries allows you to reduce your home’s carbon footprint and move closer to self-sufficiency. These systems are ideal for anyone who wants to reduce greenhouse gas emissions and minimise pollution. Solar energy systems create much less pollution than traditional fossil fuels, and by using battery storage systems, you can ensure any energy produced does not go to waste.

Minimise electric bills

You can also save considerably on your electricity costs because of the flexibility afforded. Homes and businesses can take electricity from the grid when it is cheaper and use it during peak periods (where costs can be high), creating a bliss balance between solar and grid electricity with the lowest possible costs.
