What Hocherl & Hackl does

Höcherl & Hackl GmbH (H&H) is a privately held, family-owned German manufacturer of electronic DC and AC loads, multi-channel load systems, and bidirectional power supplies used to test power supplies, energy storage devices (batteries, ultracaps, capacitors), fuel cells, PV modules, inverters, and electronic components. Founded in 1986 and headquartered in Konzell, Bavaria — where all development and production are co-located — the company sells a modular portfolio organized around five DC load series (TRL mobile regenerative, PLA compact, PLI versatile, HES high-power-density, SCL high-current), AC loads (ACL single- and three-phase), multi-channel PMLA systems scalable to 96 channels, and DC/AC power supplies including QL, Cortex, and Titan series. Proprietary regenerative grid-feedback technology (TRL line) feeds absorbed test energy back into the local power grid via a standard outlet, reducing operating cost and heat; zero-volt (ZV) models address fuel-cell testing at sub-1V voltages. Functional add-ons include MPP tracking for PV, list-function dynamic profiling with synchronous DAQ, internal-resistance measurement per DIN EN 61951/61960, and SyncroLink synchronization across devices.

The company targets industrial customers across automotive, railway, renewable energy, research and development, automation, medical, aviation, and general manufacturing through enterprise field sales supported by a worldwide distributor network (Vertriebspartner weltweit) and quote-based pricing. Revenue streams comprise hardware sales of standard and customized systems, calibration and repair services (DIN EN ISO 9001 monitored), and resale of complementary products under the November 2024 ActionPower distribution partnership. Control software (Load Control Tool, ACL/PLA/PMLA Tools) and NI-certified LabVIEW drivers extend integration into customer test environments. A generational leadership succession completed in September 2023 — with Johann Hackl's daughter assuming the managing director role — preserves family ownership continuity heading into the company's 40th anniversary in 2026.
