What A. Eberle does

A. Eberle GmbH & Co. KG is a privately held German manufacturer of measurement and control technology for electrical grids, headquartered in Nürnberg and operating since the 1980s as a GmbH & Co. KG under parent holding Ampera GP GmbH, with Managing Director Stefan Hoppert. The company's product portfolio spans power quality analyzers (the mobile PQ-Box 50/150/200/300/ONE family and the fixed PQI-DE, PQI-DA smart, and PQI-LV), voltage regulation systems (REGSys, REG-DA, and the LVRSys low-voltage longitudinal regulator), earth-fault and short-circuit indicators (EOR-1DS, EOR-3DS, EOR-D), Petersen-coil controllers (REG-DP/A), and the WebPQ private-cloud analytics platform — covering applications from low voltage to high voltage in compliance with IEC 61000-4-30 Class A and § 14a EnWG.

The company makes money primarily through hardware sales (Class A PQ analyzers and grid-control devices with 24-month standard warranties, extendable to 5 years for 19-inch systems) supplemented by a professional services stream that includes calibration, repair, loan equipment, seminars, and grid-analysis consulting. Distribution is hybrid: direct national sales teams in Germany and the Netherlands (A-Eberle Nederland B.V., Woerden), paired with an international channel-partner network across multiple regions including a 2026 addition in Mexico (Amarillo Naranja for REGSys). Customer mix spans energy utilities (ovag Netz, Kärnten Netz), research and supercomputing (Forschungszentrum Jülich's JUPITER system), and academia (FAU Erlangen-Nürnberg).

Recent strategic activity signals an acceleration phase: 2026 brought a growth partnership with Bregal (BU) explicitly targeted at international expansion, innovation, and technological development; two new product lines shipped in 2025 (PQI-LV in June 2025, PQ-Box ONE in November 2025); and the company holds ISO 9001, ISO 27001, and TÜV Rheinland certifications alongside consecutive TOP 100 Innovator (2025, 2026) and Kununu Top Company (2026) recognitions. A. Eberle maintains active marketing across website content, seminars/webinars, trade fairs, quarterly newsletters, and a customer portal, and is conducting its International Partner Week 2026 at the Nürnberg headquarters.
