What is battery storage?

As part of the big switch to green energy, battery storage is playing a key part in our transition from fossil fuels.

But what exactly is battery storage?

Battery Storage Systems (also known as Battery Energy Storage Systems (BESS)) are energy storage devices that work in tandem with solar and wind energy generating devices such as Solar PV and which can then be utilised at any point by the company utilising the storage device.

Battery Storage Systems predominantly used Lithium-ion battery technology like those found in mobile phones, laptops and electric vehicles and allow the potential of Solar Power to be utilised 24/7. One of the big negatives of solar power has always been that they need the sun and during the hours of darkness, they cannot generate electricity for us. With battery storage systems, we can charge the battery during the day when there is sunlight and then utilise this stored energy in the night time when the solar panels are not able to complete this task – they are filling the energy gap and allowing businesses to us green energy 24 hours a day.
Of course, the battery storage systems that we installed are far more advanced than rechargeable AA batteries you may use at home. Battery storage systems use complex algorithms to calculate when to store and when to release battery storage energy. All to keep your energy costs down and retaining maximum efficiency.

By managing this energy storage and release, we can depend more on green energy and rely less on the national grid and fossil fuel/carbon intense energy which will help us to achieve net-zero a lot faster.

How battery storage works

Link devices

Energy is produced, converted and fed to the distribution board through renewable technology

Charge the battery

Electricity is supplied to your property as normal. When this exceeds demand a control system diverts the power to the battery

Utilise the battery

Once immediate electricity demand exceeds generation levels, power will be drawn from the battery


When the battery is full, any surplus electricity is fed back to the grid as normal
