WEM3080T — See What’s Really Happening in Your Three-Phase Power System

Most three-phase systems look fine — until you try to understand where the energy actually goes.

Solar production, grid import, and load consumption often share the same electrical infrastructure.
Without the right meter, the data stays fragmented, misleading, or incomplete.

WEM3080T is designed to solve exactly this problem.

The hidden problem in many power systems

In many electrical installations — whether single-phase, split-phase, or three-phase — users often face questions like:

• Why does my electricity bill stay high after installing solar?
• Am I exporting energy or consuming it directly?
• Which line or phase is overloaded or imbalanced?
• Can I trust the numbers from my inverter or utility meter?

Traditional energy meters often focus on total energy only, but hide what matters most: direction, line or phase behavior, and context.

Scenario 1 — When solar and grid share the same connection

In a solar PV system, energy continuously flows between the inverter, the grid, and household loads.

Without proper system-level monitoring:

• Solar generation and grid interaction are mixed together
• Self-consumption cannot be measured accurately
• Users rely on inverter data that shows production only, not real energy flow

How WEM3080T solves this

WEM3080T measures import and export energy on each line or phase at the grid connection point, allowing you to see:

• Energy exported to the grid
• Energy imported from the grid
• Direct self-consumption and total savings

One meter for complete solar + grid visibility

By monitoring energy flow at the grid connection,a single WEM3080T can provide a complete view of the entire residential solar system.

For single-phase and split-phase solar systems, one meter is enough to:

• Monitor total solar generation
• Track grid import and export
• Understand how solar energy is actually used by household loads

This approach works independently of the inverter brand or model. Whether your system uses a string inverter, hybrid inverter, or microinverters, WEM3080T captures the real energy flow without depending on inverter vendor monitoring platforms or dedicated data loggers.

Only in installations where both the grid connection and the solar inverter are three-phase is it recommended to use two meters to monitor grid interaction and inverter output separately.

This approach provides a system-level view of your solar installation,showing how energy is generated, consumed, and exchanged with the grid —all with a single, inverter-independent energy meter.

Scenario 2 — When power flows become hard to understand across phases

In many electrical systems — whether single-phase, split-phase, or three-phase — energy consumption is often uneven and time-dependent.

Common challenges include:

• One line or phase carrying most of the load
• Peak-time usage driving unexpectedly high bills
• No clear breakdown by tariff or time period
• Difficulty correlating load behavior with billing data

How WEM3080T solves this

WEM3080T monitors voltage, current, and complete power & energy metrics on each line or phase, making it suitable for single-phase, split-phase, and three-phase systems.

This includes active and reactive power/energy, as well as power factor (PF), which are essential for accurate billing and load analysis.

This enables:

• Clear visibility of load distribution across lines or phases
• Electricity billing analysis based on time-of-use tariffs
• Long-term energy consumption analysis and forecasting

Instead of guessing where costs come from, WEM3080T turns energy usage into clear, explainable data that aligns with how electricity is billed in the real world.

Scenario 3 — When your energy data is locked in one platform

Many energy meters work only inside closed systems.

This creates problems when you want to:

• Integrate with Home Assistant or automation rules
• Store data locally or on your own server
• Combine energy data with other sensors

How WEM3080T solves this

WEM3080T is built around open interfaces, supporting:

• MQTT, HTTP, TCP/TLS data upload
• Modbus TCP / RTU
• Native integrations with Home Assistant, Node-RED, openHAB, and more

This gives you full ownership of your energy data — whether you choose a cloud-based dashboard, a local system,or a fully self-hosted energy platform.

What WEM3080T actually gives you

Together, these capabilities make WEM3080T more than a power meter. It is a system-level energy measurement foundation for solar monitoring, energy management, and automation —designed to work across different electrical systems and independent of vendor-specific platforms.

Instead of raw numbers, WEM3080T delivers actionable visibility across different electrical systems:

• Clear separation of solar, grid, and load energy
• Line- or phase-level insights for optimization
• Reliable data for billing, automation, and reporting

This makes WEM3080T suitable for:

• Single-phase, split-phase, and three-phase solar PV systems
• Residential and commercial energy monitoring
• Smart energy and automation projects
