Please visit the IAMMETER-Cloud Solar PV Monitoring System to log in to the demo account and explore all the features of our solar PV monitoring platform.
The user interface will vary depending on whether you access the demo link via a computer or a smartphone.
When accessed from a computer, the interface matches the IAMMETER web portal. When accessed from a mobile phone, it reflects the IAMMETER app interface. We recommend using a computer to explore the full range of features and reports.
Our solar PV monitoring solution includes:
Bi-directional Wi-Fi power meters: the single-phase energy meter (WEM3080) and the three-phase energy meter (WEM3080T, WEM3046T, WEM3050T).
| Hardware | Phase | CT Rating | IAMMETER-cloud | NEM | Reactive | Remark |
|---|---|---|---|---|---|---|
| WEM3080T | 3 | 150,250,500 | Yes | Yes | Yes | |
| WEM3046T | 3 | N/A | Yes | Yes | Yes | CT is not in package |
| WEM3050T | 3 | 150 | 3 Months | Yes | Yes |
NEM: Net energy metering
Reactive: The system measures both active (KW,KWH) and reactive (KVAR,KVARH) parameters.
For the WEM3080T series, each model includes three CTs and one meter. The CT cannot be replaced by the customer after the energy meter leaves the factory. It offers three types of CTs: 150A (16mm), 250A (24mm), and 500A (35mm), corresponding to the models WEM3080T-150, WEM3080T-250, and WEM3080T-500 respectively.
For the WEM3046T, the package includes only one energy meter, with no CT included. Customers need to select the CT (XXX:5A) themselves. If you need to monitor a higher amperage, the WEM3046T is a suitable option. You can purchase a WEM3046T and choose three CTs based on the current range. It's easy to find a CT with a 5A output, such as 1000:5, 1500:5, or 2000:5, etc. It's recommended to select CTs with an accuracy of class 0.5 or higher (class 0.1).
For WEM3050T, it offers nearly all the features of the WEM3080T, with the key difference being the cloud service package. WEM3050T includes lifetime access to the basic IAMMETER-Cloud service and a 1-month trial of the Pro service. In contrast, WEM3080T provides permanent access to the Pro version of IAMMETER-Cloud. If you do not require long-term Pro cloud features, WEM3050T is a more cost-effective option.
Solar PV monitoring platforms: IAMMETER-Cloud or IAMMETER-Docker.
IAMMETER provides multiple models of Wi-Fi energy meters that support bi-directional measurement, suitable for solar PV monitoring. These include:
All meters are bi-directional and can simultaneously measure energy consumed from the grid and exported to the grid when installed on the grid side. Key parameters such as real-time power, import/export energy, and feed-in energy are available.
If your system consists of a single-phase grid and inverter, you have two options:
We recommend using a three-phase meter, which offers several advantages:
IAMMETER is our cloud-based energy monitoring platform, accessible via web portal and mobile app. Its core features include:
You have a single-phase solar and grid system, and your intention is to measure the grid consumption as well as the energy exported to the grid . QuickStart for monitoring your solar PV system by WEM3080
By installing only one WEM3080 in your single phase solar PV system, you can monitor two-way power and energy , the energy consumed from grid and exported to grid simultaneously.
Wiring Diagram
You have a single-phase solar and grid ,and you want to monitor both of the grid and the solar in your system.
By installing only one WEM3080T in your single phase solar PV system, and clamping the first CT onto grid, the second CT onto solar inverter side and the third CT onto load if applicable (you can also leave the third CT unclamped if not needed), you can monitor "From Grid" (the energy consumed from the grid), "To Grid" (the energy imported to the grid) and the energy produced by solar inverter. You will also see the direct self-use energy and the energy consumed by your load.
Wiring Diagram
A split-phase or single-phase three-wire system is a prevalent type of single-phase electric power distribution in North America, commonly used in residential and light commercial applications. It involves supplying two 120 V AC lines to premises that are 180 degrees out of phase with each other concerning the neutral, along with a common neutral.
Because the two-phase output is balanced, measuring the inverter output can be accomplished using a single phase. This is achieved by configuring the meter to multiply the reading obtained from that single phase by two.
For more details ,please refer to Using a 3-Phase Energy Meter for Solar PV and Grid Consumption in a Split-Phase System
There are also many other different applications in different solar PV system, such as three phase grid & three phase solar inverter, or three phase grid & single phase inverter etc. For more details, please refer to More wiring diagram in solar pv monitoring system
With solar PV monitoring application on IAMMETER-cloud, it can improve self-consumption ratio for maximize the ROI of your solar PV system.

Display the chart of inverter power and feed-in power.
Display the energy flow chart of the solar PV system.
Display the energy consumption, solar yield energy, bill, self-consumption rate, and solar PV efficiency in one diagram.
Display the solar PV yield energy (hourly, daily,monthly, yearly).
Solar yield energy = direct use energy + export to enegy energy. This diagram shows the specific value of the direct ues energy and export energy.
Consumption energy= direct use energy + import from grid energy.
This diagram shows the specific value of the direct ues energy and import from grid energy.
This diagram shows both import energy and export energy together.
This report helps you analyze your energy consumption and electricity bills. Different electricity price plan have been supported in IAMMETER-Cloud, such as fix rate, tiered rate,time of use (TOU) rate and advanced TOU rate.
This report helps you analyze both expense of grid energy consumption and income of solar yield energy.
This report shows the total benifit of your solar PV system. solar yield enegy=direct self use energy + export to grid energy . so the total benifit= direct self use energy * electricity price + export to grid energy * feed-in electricity price .
This report will also help you to calculate the self-consumption rate of your solar PV system.
