Frequently Asked Questions

What is a Battery Energy Storage System (BESS)?

A Battery Energy Storage System stores excess electricity—often generated from solar PV—for use when energy demand is high or generation is low. It allows you to use more of your self-generated energy and reduce reliance on the grid.

Battery systems store surplus energy produced by your solar panels during the day. This stored energy can then be used in the evening or during cloudy periods, maximising your solar investment.

Yes, most existing solar systems can be retrofitted with a battery. Our team can assess compatibility and recommend the best setup for your needs.

  • Reduced energy bills

  • Greater energy independence

  • Enhanced use of renewable energy

  • Backup power in the event of an outage (depending on setup)

Some systems offer backup capability, allowing you to keep essential appliances running during a power cut. Let us know if this is a priority, and we can design accordingly.

We offer a range of high-performance lithium-ion battery solutions from trusted manufacturers, tailored to both domestic and commercial applications.

Yes, modern battery systems come with smart monitoring tools that let you track usage, charge levels, and performance in real time via an app or web dashboard.

Our experts provide a free assessment to evaluate your energy usage, existing systems, and goals. We then recommend the most efficient and cost-effective solution.
