A flexible configuration to BESS

Our E-STOR battery energy storage can be used individually or as multiple systems working together. This means that we can scale up to meet the power requirements of our customers. A master controller enables multiple systems to be used as one. Ideal for a site’s energy optimisation, we work with you to ensure BESS is right for you, looking at grid balancing services, cost and carbon savings, and more. We are also launching M-STOR utility battery storage in 2024.

The ‘gold standard’ in safety

Connected Energy, as a world leader in battery energy storage, has created the gold standard for managing second life EV battery use. Our systems have passed exacting energy sector compliance and validation tests and our control system communicates directly with all batteries to provide real time monitoring and control. Our modular design also means that any batteries can be easily exchanged – keeping our systems running at optimum performance.

Partnering with trusted OEMs

Our second life batteries come from leading OEM brands that we all recognise, with rigorous in-house testing processes, and have spent 10 years proving the BESS concept. We create commercial agreements with OEM partners to ensure visibility on battery health and capacity. We only work with reputable vehicle and battery manufacturers that allow us access to their own testing data to ensure the safety of the batteries we use, and the systems we built.
