For global B2B buyers—industrial OEMs, commercial distributors, and energy system integrators—three phase energy meter with WiFi is no longer a “nice-to-have” but a critical tool for managing high-power industrial and commercial energy use. Unlike single-phase meters (for residential use), three-phase models handle heavy loads (e.g., factory machinery, commercial HVAC) and require reliable remote monitoring to avoid downtime and optimize costs. Statista’s 2024 report shows global B2B demand for WiFi-enabled three phase energy meters is growing at 22% annually, with 68% of industrial clients citing “multi-circuit tracking + real-time data” as their top procurement priority. Yet 59% of buyers struggle to find solutions that balance regional grid compatibility, industrial-grade durability, and flexible integration (MarketsandMarkets, 2024 Global Industrial Energy Meter Report).
1. Why B2B Buyers Need WiFi-Enabled Three Phase Energy Meters (Data-Driven Rationale)
① Cut Remote Maintenance Costs by 35%
② Meet Regional Grid Compatibility (EU/US Focus)
③ Enable Multi-Circuit Monitoring (A Top B2B Pain Point)

OWON PC341-W-TY: Technical Specs & B2B Value Mapping
Technical Feature | PC341-W-TY Specifications | B2B Value for OEMs/Distributors/Integrators |
---|---|---|
Three Phase Compatibility | Supports 3-phase/4-wire 480Y/277VAC (EU), 120/240VAC split-phase (US), single-phase | Eliminates regional stockouts; distributors can serve EU/US clients with one SKU |
Multi-Circuit Monitoring | 200A main CT (whole facility) + 2x50A sub-CTs (individual circuits) | Reduces client equipment costs (no need for 3+ separate meters); ideal for solar/industrial use cases |
Wireless Connectivity | WiFi 802.11b/g/n (@2.4GHz) + BLE (for pairing); External magnetic antenna | External antenna solves industrial signal shielding (e.g., metal factory walls); 99.3% connectivity stability in -20℃~+55℃ environments |
Data & Measurement | 15-second reporting cycle; ±2% metering accuracy; Bi-directional measurement (consumption/production) | Meets EU/US industrial accuracy standards; 15-second data helps clients avoid overloads; bi-directional tracking for solar/battery storage |
Mounting & Durability | Wall or DIN rail mounting; Operating temp: -20℃~+55℃; Humidity: ≤90% non-condensing | DIN rail compatibility fits industrial control panels; Durable for factories, cold storage, and outdoor solar sites |
Certification & Integration | CE certified; Tuya compliant (supports automation with Tuya devices) | Fast EU customs clearance; Integrators can link PC341 to Tuya-based BMS (e.g., HVAC controllers) for automated energy savings |
Standout B2B-Centric Features
- External Magnetic Antenna: Unlike meters with internal antennas (which fail in metal-rich industrial environments), the PC341’s external antenna maintains 99.3% WiFi connectivity in factories—critical for 24/7 operations where data gaps cause downtime.
- Bi-Directional Measurement: For B2B clients in the solar/battery space (a $120B market, per IEA 2024), the PC341 tracks energy production (e.g., solar inverters) and consumption, plus excess energy exported to the grid—no need for separate production meters.
- Tuya Compliance: OEMs and integrators can white-label the PC341’s Tuya App (add client logos, custom dashboards) and link it to other Tuya smart devices (e.g., smart valves, power switches) to build end-to-end energy management systems for their B2B customers.
3. B2B Procurement Guide: How to Select the Right Three Phase Energy Meter with WiFi
① Prioritize Regional Grid Compatibility (Not “One-Size-Fits-All”)
② Verify Industrial-Grade Durability (Not Residential Quality)
③ Check Integration Flexibility (BMS & White-Labeling)
- BMS Integration: Free MQTT APIs for connection to Siemens, Schneider, and custom BMS platforms—critical for integrators building large-scale industrial energy systems.
- OEM White-Labeling: Custom App branding, pre-loaded client logos on meters, and regional certification (e.g., UKCA for the UK, FCC ID for the US) at no extra cost—ideal for OEMs selling under their own brand.
4. FAQ: Critical Questions for B2B Buyers (Three Phase & WiFi Focus)
Q1: Does the PC341 support OEM customization, and what is the minimum order quantity (MOQ)?
- Hardware: Custom CT sizes (200A/300A/500A), extended cable lengths (up to 5m) for large industrial facilities, and custom mounting brackets.
- Software: White-labeled Tuya App (add your brand colors, logos, and custom data dashboards like “industrial load trends”).
- Certification: Pre-certification for regional standards (FCC for US, UKCA for UK, VDE for EU) to speed up your market entry.
- Packaging: Custom boxes with your brand and user manuals in local languages (English, German, Spanish).
The base MOQ is 1,000 units for standard OEM orders; 500 units for clients with annual contracts exceeding 5,000 units.
Q2: Can the PC341 integrate with non-Tuya BMS systems (e.g., Siemens Desigo)?
Q3: How does the PC341 handle signal interference in industrial environments (e.g., factories with heavy machinery)?
Q4: What post-sales support does OWON provide for B2B clients (e.g., distributors with technical issues)?
- 24/7 Technical Team: Fluent in English, German, and Spanish, with a <2-hour response time for critical issues (e.g., deployment delays).
- Local Spare Parts: Warehouses in Düsseldorf (Germany) and Houston (US) for next-day shipping of PC341 components (CTs, antennas, power modules).
- Training Resources: Free online courses for your team (e.g., “PC341 BMS Integration,” “Three Phase Grid Compatibility Troubleshooting”) and a dedicated account manager for orders over 1,000 units.
5. Next Steps for B2B Buyers
- Request a Free B2B Technical Kit: Includes a PC341 sample (with 200A main CT + 50A sub-CT), CE/FCC certification docs, and a Tuya App demo (pre-loaded with industrial dashboards like “multi-circuit energy trends”).
- Get a Custom Compatibility Assessment: Share your client’s region (EU/US) and use case (e.g., “100-unit order for US split-phase commercial buildings”)—OWON’s engineers will confirm grid compatibility and recommend CT sizes.
- Book a BMS Integration Demo: See how the PC341 connects to your existing BMS (Siemens, Schneider, or custom) in a 30-minute live call, with a focus on your specific workflow (e.g., “solar production tracking”).
