As a bidirectional WiFi energy meter, our WiFi Energy Meter is highly suitable for use within a solar PV system. It efficiently measures energy "to grid" or "from grid" using just one meter. This meter uploads measurements (Voltage, Current, Active Power, Active Energy, Frequency, etc.) to the cloud, facilitating easy online monitoring of essential solar PV system Key Performance Indicators (KPIs):
We'll present the wiring diagrams for installing WiFi energy meters in solar PV systems.
For monitoring your single-phase solar PV system, you have two options to achieve this:
As illustrated below, within a single-phase solar PV system, 2 WEM3080 units can be positioned at two locations (Grid Side and Solar Inverter Side) based on your specific requirements:
Notă:
If you only wish to monitor imported/exported energy on the grid side, installing only 1 WEM3080 on the grid side is sufficient.
As depicted below, in a single-phase solar PV system, you can install 1 WEM3080T and place the CTs in different locations (Grid Side and Solar Inverter Side) as needed:
This option is recommended as it synchronizes data at one-minute intervals.
Notă:
Clamping a CT to the Load Side isn't necessary as the system calculates the total power consumed by all loads using the following formula:
Load Power = Inverter Power - Feed-in Power
As depicted below, within a three-phase solar PV system, you can install 2 WEM3080T (three-phase WiFi energy meters).
Notă:
Installing only 1 WEM3080T on the grid side is sufficient if you wish to monitor imported/exported energy on the grid side only.
This wiring diagram is no longer recommended.
We've introduced a new method to monitor the 120/240V or 120/208V systems prevalent in most North American countries now.
Only one WEM3080T/WEM3050T is required to monitor both solar and grid systems in the 120/240V and 120/208V systems.

As shown below, within a three-phase solar PV system, you can install 1 WEM3080 (single-phase WiFi energy meter) and 1 WEM3080T (three-phase WiFi energy meter).
Notă:
For monitoring imported/exported energy on the grid side only, installing 1 WEM3080T on the grid side suffices. WEM3080T is applicable in single-phase, split-phase, and three-phase systems.
Only one WEM3080T/WEM3050T is needed to monitor both solar and grid systems in the 120/240V and 120/208V systems.
