From design to operation
Where Socomec truly stands apart is in the way we support you — every step of the way.
We don’t just supply components. We engineer full systems, tailored to your needs, and guide you from the first sizing study through to commissioning, training, remote monitoring and maintenance.
We are supported by a network of 450 experts, a dedicated ESS testing lab, local stock availability and a proven support model across 80 countries globally.
Our dedicated teams of project managers, system engineers, and service experts support our customers globally throughout the entire project lifecycle—from design to commissioning and beyond—providing peace of mind and long-term value. Our systems have embedded in-house developed softwares with AI-powered digital services for real-time control, performance optimization, and full system visibility.
ESS Grid Lab
Our dedicated testing facility
State-of-the-art facility
Socomec’s new 500 m² ESS Grid Lab is equipped with cutting-edge technology to enhance grid security, resilience and reliability. This state-of-the-art facility offers a modular testing environment that replicates various storage project conditions through an on-site microgrid.
Ensuring project success
Our centre enables the testing of energy storage projects that would otherwise be unfeasible on real-world networks. By simulating global grids with different local voltage and frequency types, we ensure your project’s success before installation in the field. This means you can confidently deploy your systems, knowing they will perform as expected.
Industry-leading training and expertise
The ESS Grid Lab also provides industry-leading training and expertise, fostering collaboration across sectors. We invite partners to join us for Energy Management System (EMS) qualifications, ensuring you have the skills and knowledge to excel in the evolving energy landscape.
Comprehensive testing capabilities
Our facility includes a 3 MW microgrid, scalable energy storage systems and an Electric Vehicle Charging Infrastructure (EVCI) platform.
