Client testimonies
Due to the current environmental challenges, Delhaize makes sustainable innovation one of its priorities. Sustainability has been a fixture in Delhaize stores for years. But now Delhaize shifts up a gear and comes up with a first: the reuse of electric car batteries as a backup energy source for the store in the event of a power cut. To this end, Delhaize works together with Watt4ever who converts the batteries into sustainable energy storage systems for our stores.
We installed our very first battery storage system with Watt4Ever to provide flexibility services to the electricity grid. The support and reactivity of Watt4Ever’s after-sales team have been instrumental in making our project a success.
We have been using Watt4Ever’s modules to build our innovative, custom-made battery energy systems for over a year now. Their support, reliability and precision have been precious in developing our energy storage business.
