A brighter, more independent future

Take control of your energy. Store more. Waste less.

At EOTA, we provide expert battery storage installation for homes and businesses across Kent, including Sevenoaks, Orpington, Tonbridge, West Malling, and the wider South East. Battery storage empowers you to make the most of your electricity — storing it when it’s cheap or abundant, and using it when you need it most.


Whether you're looking to maximise your solar panel system, reduce reliance on the grid, or future-proof your home against rising energy costs, we’re here to help. And as a social enterprise, we reinvest 50% of our profits into community sustainability projects — helping others while helping you.

Battery Storage

Why Choose Battery Storage?

Battery storage gives you full control over your energy. When paired with solar, batteries store surplus electricity generated during the day and release it at night, when your demand peaks. Even without solar, you can use a battery to store electricity from the grid at cheaper off-peak rates — and avoid costly peak-time usage.

Key Benefits:

  • Reduce energy bills and reliance on utility providers

  • Maximise your solar self-consumption

  • Store low-cost energy for use during peak hours

  • Use stored power during outages (brand dependent)

  • Improve your Energy Performance Certificate (EPC) rating

  • Lower your carbon footprint

Battery Storage for Homes

Our domestic battery storage systems are tailored to your property and lifestyle. Whether you're retrofitting to an existing solar PV system or installing as part of a whole-home energy package, we’ll help you find a battery solution that works.


We offer both AC-coupled and hybrid systems, including smart monitoring apps, modular designs, and solar integration options. Battery capacities typically range from 5kWh to 15kWh for homes, with scalable options available.

Battery Storage for Businesses

Commercial energy storage helps businesses lower overheads, manage peak demand, and achieve sustainability goals. We design and install high-capacity battery storage systems for:

  • Office buildings and retail units

  • Warehouses and industrial premises

  • Schools, colleges, and community facilities

  • Housing developers and multi-tenant buildings


A well-designed system can help you:

  • Cut grid energy usage and demand charges

  • Offset EV charging and HVAC loads

  • Improve ESG and environmental reporting

  • Increase energy independence and site resilience

  • Prepare for future grid balancing and energy trading

Each battery system includes a smart monitoring platform, allowing you to:

  • View battery state of charge

  • Track daily, monthly, and annual energy savings

Solar + Battery
= Energy Independence

If you already have solar panels, a battery helps you store excess daytime energy for use in the evening or overnight. This reduces the need to export energy at low rates and buy it back later at higher prices.

Don’t have solar yet? No problem. We also install fully integrated solar + battery systems, allowing you to:

  • Run your home mostly on renewable power

  • Charge your EV using solar energy

  • Store backup power in case of outages

  • Offset demand from electric heating, aircon or appliances

Our team will help you design a future-ready energy setup that suits your property and goals.
