ees AWARD Finalist Interview: SOCOMEC’s New Battery Inverters | Cyril Carpentier, Business Developer for Germany, SOCOMEC

SOCOMEC was founded in 1922 to supervise and secure low voltage grids with a special focus on energetic efficiency for their customers. They give about 10 percent of their revenue back to research and development to expand safe energy supply and set their goal to always being up-to-date on new technology. Based in France and Italy, SOCOMEC works with the principle of lean management to fulfil their customers’ expectations regarding quality, deadlines and prices. Their battery inverters „SUNSYS PCS2” and „SUNSYS PCS2IM” works highly efficient in combination with its battery units. The ees International met with Cyril Carpentier to speak about the company’s research and vision for their future.

ees International: The ees AWARD expert panel is honouring pioneering energy storage solutions. What is exceptional and new about your nominated product?

We developed more than two years ago our SUNSYS PCS² IM range, which are energy storage converters that have the grid forming capability to work in island grid applications. This was already big news on the market.

Now we go a step further by proposing a complete system, from 33kW to a few MW, to provide resiliency to grid-tied microgrids and energy availability for rural or island electrification, based on a control software that we developed internally. This system includes everything; power converters, batteries, AC/DC combiner cabinets and control cabinet that manage locally the microgrid and energy sources: grid, genset, wind, PV.

Our system is based on a modular architecture with some elements that are common to each project (SUNSYS PCS² IM and Batteries) and some specific elements (Microgrid Control Module and Paralleling cabinets) that need to be adapted to each projects.

The system we are offering is unique, as it makes available a wide power and energy range dedicated to microgrid applications. Moreover it uses a power converter that has a grid forming capability with high overload and short circuit capability, essential characteristics for microgrid applications.

By delivering the turnkey system, we make it easier on a customer point of view: we are the single point of responsibility for the operation of the entire system and by designing the system immediately as a whole and not as a patchwork of components, we ensure that the protections, synchronising devices, power converters and batteries are all compatible. We are also in charge of the Maintenance services of the entire system.

This system offers a cost-effective solution, to provide electricity to an isolated area, in comparison with the cost of the construction of a new grid, which is really important in isolated areas.

The system also allows decreasing significantly the diesel consumption of the gensets and thus increases their life duration and efficiency. In situation in which a grid already exists, it helps at improving the resiliency of the microgrid in case of blackouts.

Finally, in the environmental context of increase of renewable production and decrease of carbon emissions, the system also aims at maximising the PV integration.

ees International: Apart from your nominated product what were your company’s milestones in the last two years?

We are happy to say that we also developed a customised offer dedicated to the Commercial & Industrial applications. This offer, which goes from 33kVA/92kWH to 800kVA/1,1MWh, is a modular and scalable one; this means that converters and/or batteries can be added later on according to the size increase of the installation.

We also got the UL9540 SA certification for this system, enabling us to enter and establish ourselves well in the USA C&I market.

ees International: Renewable energy markets around the world are prospering every year. What is your company’s vision for the energy storage markets around the world?

From what we can see the market is really developing everywhere and business models are still not 100% defined yet.

Utility scale applications still seem to have the brightest future however we can see an increasing market for commercial and industrial applications in Europe, including electrical vehicles charging stations and some applications for rural electrification.

ees International: What are your expectations as an exhibitor at the ees Europe, which is taking place from 20 to 22 June 2018 in Munich, Germany?

We are exhibiting in Munich with the aim of increasing our image as players in the energy storage field.

We hope to see some of our existing customers / partners but also to meet new prospects and make them discover our complete offer range dedicated to Energy Storage from 33 kW to MW.
