WEM3050T: $109 Wi-Fi Energy Meter for Residential Solar Users and Installers | IAMMETER
1. WEM3050T: A Bidirectional Energy Meter Designed for Home Solar Monitoring
The WEM3050T is IAMMETER's budget-friendly three-phase Wi-Fi energy meter, built for bidirectional metering. It supports real-time monitoring of both solar generation and grid consumption, making it an excellent entry-level option for residential solar PV systems.
Key Benefits:
- Three-phase bidirectional measurement: Accurately tracks solar energy generation, household consumption, and energy exported back to the grid.
- Ideal for residential rooftop PV systems: One unit can monitor a single-phase grid + single-phase inverter or a split-phase grid + split-phase inverter (example). For three-phase grid + three-phase inverter monitoring, two WEM3050T units are required.
- Wi-Fi connectivity: Uploads data in real time to IAMMETER-Cloud, accessible via mobile app or web dashboard.

Paired with IAMMETER-Cloud Basic, the WEM3050T offers comprehensive PV system monitoring at zero subscription cost—perfect for most home users and small projects.
Core Functions:
- Real-time monitoring of solar generation, consumption, and grid exchange
- Daily/monthly/yearly energy trend analysis
- Data export and basic alert features
- Centralized device management — ideal for solar installers managing multiple customers
3. How WEM3050T Empowers Solar Installers
The WEM3050T is not just a consumer-grade tool — it’s also a reliable and scalable solution for solar installers. Its ease of deployment and cloud-based management make it a valuable addition to any solar project.
