What PQ Plus does

PQ Plus GmbH is a privately held German manufacturer founded around 1998–2000 and headquartered in Langensendelbach, Bavaria, specializing in energy measurement and power quality monitoring technology for industrial, utility, data center, healthcare, and building-sector customers. Its product portfolio spans Class A and Class S power quality analyzers (UMD series), MID-compliant energy meters (CMD series) with PTB approvals for billing-grade metering, modular outgoing feeder measurement systems with proprietary 333 mV current transformers, and reactive power compensators, complemented by the ENVIS/EnVisWeb/GridCal software platforms for data acquisition, EN 50160/EN 61000 network analysis, and digital distribution grid management. The company supports industrial integration via Modbus RTU/TCP, M-Bus, SNMP, MQTT, Siemens Simatic S7 PLCs, and EPLAN/PARTcommunity engineering workflows, and has expanded into IoT with LoRaWAN interfaces and Universal Gateway X Series accessories.

PQ Plus generates revenue through four streams: hardware product sales, recurring software licenses (ENVIS, GridCal), professional engineering services (on-site analysis, commissioning, EN 50160 network analyses, staff training), and paid training (ENVIS/EnVisWeb courses at €1,000/day). Go-to-market combines direct sales from headquarters with an extensive regional channel partner network covering Germany (Engineering Office Beyer North/South, STAPF, ecosmart ENERGY, BIW, WARRELMANN & KLAPP, Jörg Bobert, PQ Plus NRW) and international distributors in Austria (Pri:Logy Systems), Switzerland (Schotec AG), Benelux (Frakol Power Quality), and Southeast Europe (Machinor S.A.). The firm is management-owned, led by three managing directors (Marita Beyer, Anna Beyer, Daniel Fierus-Beyer), holds ISO 9001, ISO 14001, ISO/IEC 27001, and CrefoZert certifications, and has not disclosed external funding, M&A activity, or named end-customer logos.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Kamax: Smaller German specialist in current transformers and Rogowski coils for power monitoring — adjacent competitor sharing the 333 mV CT signal standard used in PQ Plus modular feeder measurement, often co-deployed with PQ Plus products.

Broad incumbents

• ABB: Global electrification and automation giant offering ABB Ability energy and asset manager plus CMS-700 circuit monitoring systems — overlaps with PQ Plus in power quality but operates at massive scale across utilities, industry, and transport.
• Siemens: SENTRON portfolio (7KM PAC measuring devices, SICAM, powermanager) competes directly with PQ Plus power quality and energy measurement products, with deep Modbus/Siemens PLC integration that mirrors PQ Plus's Simatic S7 couplings but at vastly greater scale.
• Eaton: US-headquartered power management major offering Power Xpert Meter, IQ Analyzer, and Foreseer energy management software — overlaps with PQ Plus's energy monitoring and power quality stack, with a much broader electrical portfolio and global footprint.
• Schneider Electric: Global energy management and automation major offering PowerLogic ION/EcoStruxure Power Monitoring Expert — competes broadly with PQ Plus in power quality and metering but as part of a much larger portfolio including switchgear, UPS, and building management systems.

Others

• WAGO: German electrical interconnection and automation specialist offering power measurement modules (879-30xx series) integrated with WAGO-I/O-SYSTEM — competes in adjacent smart-grid/building automation but as an enabling/integrated ecosystem rather than a direct power-quality analyzer vendor.

Direct peers

• Socomec: French manufacturer specializing in power monitoring solutions including DIRIS Digiware and DIRIS A-40 power quality analyzers, targeting industrial, data center, and building applications — directly overlapping with PQ Plus's modular outgoing feeder and Class A/S measurement value proposition.
• Janitza Electronics: German-headquartered specialist in Class A power quality monitoring devices, energy meters, and GridVis software — the closest direct competitor to PQ Plus with overlapping product categories (UMG series vs. UMD series) and a similar DACH-centric channel model.
• Carlo Gavazzi: Swiss/Italian industrial automation and energy management company offering EM energy meters, WM power analyzers, and modular solutions for industrial and building automation — directly comparable product portfolio and European channel model.
• DEIF: Danish power management solutions provider offering MIC, MIB, and MIC-2 power quality analyzers and energy meters for marine, offshore, and industrial markets — overlapping hardware portfolio with similar EN 50160 / IEC 61000 compliance focus.
