What is commercial battery storage?

Battery storage systems store the electricity generated by your solar PV system or from the grid, so it can be used later when energy demand or prices are higher.

By integrating solar power and battery storage, your business can operate more efficiently, consuming your own clean energy, reducing export losses, and avoiding expensive peak-rate tariffs.

Battery systems can also provide backup power during outages, supporting critical operations and improving resilience.

ZLC Energy designs, installs, and maintains commercial battery storage systems across the UK, using high-performance, scalable technology systems.

How Battery Storage Works

Battery storage lets businesses take full advantage of renewable energy by storing electricity when it’s available and using it when it’s needed most. This helps companies maximise their use of clean power, reduce reliance on the grid, and maintain operations sustainably and efficiently.

1
Store Clean Energy

Capture excess electricity from onsite solar or wind and save it for times of high demand.

2
Use Energy on Demand

Release stored energy instantly to keep operations running and reduce reliance on the grid.

3
Maximise Efficiency

Smart systems prioritise renewable energy use, cutting costs and helping you meet sustainability goals.
