Battery Storage

underlines brand colours

Having the ability to store your renewable energy is a game-changer for businesses across the globe. The evolution of commercial battery storage solutions allows organisations to control their energy now as they plan for the future.

Installing battery storage solutions on-site offers your business the ability to store and discharge electricity to meet demand and potentially operate independently from the grid with backup power when demand is high.

Immersa turnkey solutions for battery storage include analysing your business to tailor the best technologies. We then design and plan your system through installation and aftercare.

Creating commercial energy-efficient battery storage systems

It is possible to install battery storage as a standalone product to store energy from the grid when tariffs are lower. To make battery storage a truly efficient part of your renewable energy future requires integration with commercial solar PV. Although other renewable solutions are on the market, solar PV is more affordable and is easier to achieve planning consent. You can read more about commercial solar PV here.

Our commercial battery storage partner, CellCube Energy, has been pioneering energy storage infrastructure for 15 years. The CellCube energy storage system provides clean and emission-free power. Certified with international standards, they have wide temperature tolerances, and containerisation allows easy transport and relocation. The modular design allows for plug & play clustering and grid expansion.

The benefits of energy storage for business

Now is the time to decide on energy storage; here's why:

sustainable energy


Store your clean solar energy to reduce reliance on fossil fuels and spiralling grid energy costs.

backup power


Use battery energy and remain operational in the event of a grid power outage or energy rationing.

peak shaving


Discharge your stored self-generated energy at times of peak demand and avoid peak-time energy costs.



Build and expand your energy network and operate independently from the National Grid.

Scalable and flexible battery storage that put you in control of your energy future

Our reliance on fossil fuels is reducing year on year, but the UK is many decades away from net-zero. Although generating renewable energy is a top priority for power providers changing an infrastructure 100 years in the making will take a substantial financial investment. With investors still expecting a dividend, your energy bills will rise sharply over the coming years.

The only way to ensure your business controls its energy costs is to invest in your energy future - now. As your professional renewable energy expert, Immersa will help you plan, implement and manage your commercial Solar PV and Energy Storage System (ESS). Our team will ensure you maximise the power you generate and store to reduce the energy you buy from the grid and manage any excess energy you sell back into the grid.
