What AEconversion does
AEconversion GmbH & Co. KG is a privately held, owner-managed German power electronics company founded in 2012 and headquartered in Bad Sassendorf, Germany. The company develops and manufactures customized AC/DC converters, DC/DC converters, battery chargers, and solar micro-inverters, performing the full development lifecycle in-house — mechanical design, circuit design, PCB layout, magnetic component design, embedded software, EMC compliance, approval certification, and series production. Core technical differentiators include the use of wide-bandgap semiconductors (SiC and GaN) for efficiency, advanced thermal management across convection, contact, and liquid cooling, IP6K9K-grade enclosure protection, and a proprietary building block library of field-proven circuits accumulated from over 100 prior devices. The team reports 30+ years of cumulative engineering experience, and the company has cumulatively delivered more than 375,000 devices.
The business operates two distinct product and channel motions. The primary line is custom OEM power electronics, sold directly by Managing Director Stefan Größbrink and the engineering team to enterprise customers across industrial automation, electronic test systems, building/access technology, electric mobility, automotive production (including a documented BMW production-cell deployment), data centers, and medical devices. Pricing is quote-based and not publicly disclosed, with revenue tied to development services followed by recurring series production orders — the company reports a 100% reorder rate for further development projects after initial series production, indicating high customer retention and embedded switching costs. A secondary line consists of standardized micro-inverters (INV500-90 dual-module up to 700W with Powerline communication, and INV315-50 single-module up to 400W for direct module mounting), sold partly through the eBay Germany marketplace to residential solar end customers. Manufacturing is split between Germany (for quality-sensitive and regulated runs) and China (for cost-efficient series production), giving the company flexibility on cost-versus-quality positioning per program.
Geographically the company claims worldwide operations while remaining structurally small and owner-managed, with no external investors, no parent company, and no public listing. Marketing is largely content-led, emphasizing thought leadership on DC grids, thermal management, and IP protection classes via technical articles, LinkedIn, YouTube, Instagram, and Xing. The most strategically significant recent moves have been the extension of DC grid technology into data center and automotive production applications, the establishment of Asian manufacturing, and the build-out of an electric mobility practice around bidirectional EV charging.
