Germany 1MW Energy Storage Cabinet DC-Link Upgrade

A German ESS integrator replaced imported DC-Link film capacitors with our MKP series and cut BOM cost by 22% while improving ripple current margin.

Challenge. The customer required a certified, cost-effective alternative to an existing European or Japanese brand with a short qualification cycle.

Solution. We provided engineering samples within 5 working days, full AEC-Q200 / VDE / UL test data, and a tailored packing plan for automated SMT lines.

Result. Cost -22% · Ripple +35% · Lead time 18 days. The project moved to mass production and has been running for consecutive quarters without quality claims.
