Germany's Heckert Solar launches C&I energy storage brand

Benjamin Trinkerl, managing director of solar module manufacturer Heckert Solar, now has the same role at a new company: DSW Deutsche Speicherwerke GmbH has moved to the Heckert site, in the German city of Chemnitz.

Speicherwerke roughly translates as “storage works” and the new business will make BESS to be sold by Heckert Solar, whose owners the Trinkerl family control both companies.

Announcing its launch, DSW Deutsche Speicherwerke said it would set “new standards in large-scale [energy] storage technology and offers customized, scalable energy storage systems for industry, commerce, agriculture, and critical infrastructure.”

The only product for which a data sheet was available on the company’s website at the time of writing was a 125 kW/261 kWh DSW BESS 261 model bearing the logo of state-owned China Railway Rolling Stock Corporation (CRRC), which makes batteries in addition to railway carriages. That lithium ferro-phosphate battery, whose modules can be expanded into a BESS with around 2 MWh of storage capacity, has previously been marketed by Meister-Energiehaus GmbH in Aldingen Aixheim, Germany.

DSW Deutsche Speicherwerke told pv magazine its sales would begin this month, “after all the necessary organizational and sales framework conditions have been created.”

No information was available about a DSW BESS 745 model, which has also been announced.

Heckert Solar said the variant of CRRC’s 125 kW/261 kWh battery offered by DSW Deutsche Speicherwerke was “developed and adapted specifically for the European market in collaboration with CRRC.” That involved “both technical and regulatory adjustments to ensure the highest safety and efficiency standards for our customers in Europe,” said the company.

Sales of the system under the DSW logo will initially start in Germany, Austria, Switzerland, and Italy. Gradual expansion into other markets is being planned and the newly-launched battery maker said it is “individually reviewing requests from other regions and can implement projects flexibly.”
