WEM3080 Single-phase Wi-Fi Energy Meter for Grid or Inverter Monitoring | IAMMETER

 WEM3080 Single-phase WiFi Energy Meter for Grid or Inverter Monitoring

WEM3080 single-phase Wi-Fi energy meter

 

The WEM3080 is a single-phase smart energy meter wifi for monitoring one single-phase circuit.

 

It can measure voltage, current, active power, energy consumption, and bidirectional import/export energy. It is suitable for:

 

Single-phase grid-side monitoring

Single-phase solar inverter output monitoring

A single branch circuit or dedicated load

Home Assistant, MQTT, Modbus/TCP, and API integration

For home solar PV users, WEM3080 is useful when you only need to measure one point, such as the grid side or the inverter output.

 

However, one WEM3080 alone cannot provide complete home solar monitoring because complete solar analysis usually needs both grid-side data and solar production data. To calculate home consumption, self-consumption, grid import/export, and solar savings, use WEM2067, WEM3050T, or a multi-meter setup.

Where WEM3080 Fits in Home Solar Monitoring

WEM3080 is a single-channel energy meter wifi. This makes it simple and reliable for one measurement point, but it also defines its limitation.

 

For solar PV monitoring:

 

If WEM3080 is installed on the grid side, it can measure grid import/export.

If WEM3080 is installed on the inverter side, it can measure solar production.

If only one WEM3080 is installed, IAMMETER cannot calculate the complete solar energy flow by itself.

For complete home solar monitoring, the system normally needs:

 

Grid import/export measurement

Solar inverter production measurement

Home consumption calculation

Self-consumption analysis

Electricity bill, feed-in income, and savings reports

Recommended options:

 

WEM2067: dual-channel meter for single-phase home solar with grid + inverter monitoring

WEM3050T: flexible meter for single-phase, split-phase, and three-phase home solar scenarios

Home Solar Wiring Diagram

Best-use Scenarios

Single-phase Grid Monitoring

Install WEM3080 on the single-phase grid side to monitor:

 

Real-time home power

Grid import

Grid export if a solar PV system is connected

Daily and monthly grid energy

Electricity usage trend

This is useful for basic home energy monitoring and for users who mainly want to understand grid-side power flow.

 

Single-phase Solar Inverter Monitoring

Install WEM3080 on the output of a single-phase solar inverter to monitor:

 

Solar production power

Daily solar generation

Monthly and yearly solar generation trend

This is useful when you only need inverter output data or when WEM3080 is used together with another IAMMETER meter on the grid side.

 

Single Load or Branch Circuit Monitoring

WEM3080 can also monitor one dedicated load or branch circuit, such as:

 

EV charger branch circuit

Heat pump or HVAC circuit for measurement only

Workshop or small office circuit

A single appliance group

This use case is for monitoring and analysis, not load control.

 

What You Can Monitor

WEM3080 can measure:

 

Voltage

Current

Active power

Energy consumption

Import/export energy

Real-time and historical data

In IAMMETER-Cloud, the data can be used for:

 

Real-time monitoring

Daily and monthly energy analysis

Electricity bill reports

Home energy monitoring

Solar production or grid import/export monitoring, depending on installation position

Important Limitation for Solar Users

WEM3080 should not be described as a complete single-device home solar monitoring solution.

 

Because it has only one measurement channel, it cannot simultaneously measure both:

 

Grid import/export

Solar inverter output

If a user wants to see solar production, home consumption, grid import/export, self-consumption rate, and savings in one complete solar dashboard, recommend:

 

WEM2067 for simple energy meter single phase 

WEM3050T for more flexible home solar systems

WEM3080T or WEM3046T for professional or high-current scenarios

Local Integration and Smart Home Use

WEM3080 supports open data access and is suitable for smart home and integration users.

 

Integration options include:

 

Local API

MQTT

Modbus/TCP

HTTP/HTTPS upload

Home Assistant

Node-RED

OpenHAB

Grafana / InfluxDB

WEM3080 vs WEM2067 vs WEM3050T

 

Choose WEM3080 when one measurement point is enough.

 

Choose WEM2067 or WEM3050T when the goal is complete home solar monitoring.
