Stationary Battery Storage Systems
Batteries provide a cost-effective solution to store power and supply it when required. Stationary battery systems can be used to provide backup power to buildings locally or securing the grid stability, by storing energy from renewable sources such as solar or wind. Moreover, as battery manufacturers look towards product lifetime solutions, stationary battery storage could provide a second life for EV batteries.
As a BESS power electronics expert, Watt&Well is actively supporting the energy transition:
- We are part of the Shift2DC Horizon Europe project, promoting the adoption of decentralized Direct Current (DC) microgrids.
- We are members of the Current/OS Foundation, which develops an open standard for DC distribution to enhance resilience, sustainability, and safety in electrical networks.

Wave Energy Converter (WEC)
Since 2017, Watt&Well, as a power electronics provider for renewables projects, has been working with SBM Offshore since 2017 to develop its innovative WEC S3® Wave Energy Convertor.
This new generation wave energy convertor system marks the first step towards harnessing large scale, commercially viable wave energy. It moves beyond the barriers inherent in the industry’s conventional wave energy devices, which have met technical and economic limitations.
The WEC S3® Wave Energy Convertor features direct energy conversion from waves to electricity by application of Electro Active Polymers. Energy is generated through a series of dielectric elastomer generators (DEG) which charge kinetic energy as the polymers are stretched and discharges energy as they are relaxed.
The flexible floater and its mooring system require minimum maintenance and have already been successfully tested in a model basin facility. Watt & Well has developed the onshore and offshore electronics components of the prototype. This include power conversion, measurement and monitoring of the complete equipment. Initially modelled at the Ecole Centrale de Nantes, the WEC S3® is supported by the French government’s ecological transition agency (ADEME) Future Investments Program, as well as the Principality of Monaco.
Quality management.
Our product design and production systems are qualified according to the ISO9001 Quality Management System. Our standards and procedures enable us to deliver products and services in accordance with customer and regulatory requirements. Final assembly and product testing is done in-house. We carry out in-depth validation of all produced converters at full power and maximum temperature, as well as burning tests to avoid youth failure on.
