What our customers say


The benefits of solar batteries


Energy Cost Optimise

Storing excess energy and using it during times of higher electricity rates, you can further reduce your electricity bills.


Grid Resilience

Solar batteries act as a backup power source during grid outages, ensuring that essentials continue to operate.


Energy independence

Generating your own power allows you to become less reliant on utility companies and the fluctuating costs.


Demand Management

Solar batteries allow you to draw stored energy during peak demand periods when electricity costs are highest.


Environmental Impact

Using stored solar energy instead of relying solely on the grid, you contribute to a cleaner environment.


Long term Savings

Solar batteries extend the lifespan of your solar panels by reducing wear and tear caused by frequent on-off cycles.

Our Services

ERS Group specialise in customised solar PV systems and battery storage solutions that enable you to take control of your energy. With over a decade of experience, our team of experts excel at design and installation and can tailor a system to meet the unique needs of your business.


We understand that no two solar projects are the same. From your business operations and premises to your energy usage and overall goals, many factors will inform your solar and battery storage system’s sizing and configuration. Our consultative process considers all of these variables to create the best installation for you using high quality materials and components to ensure your system is built to last.


Assessing your business's needs

Firstly, evaluate your current energy usage and assess your existing load profile to see how it aligns with your solar generation. It’s also important to understand if different tariff rates apply to your business at different times of the day. This will all help determine the right storage capacity for your needs. Don’t forget to take into account future plans for growth, or electrification such as EV charging stations and build in capacity.
