Quickly Monitor Your Home Solar System Using WEM3050T

 How to Quickly Monitor Your Home Solar System Using the WEM3050T Wi-Fi Energy Meter

Monitoring your home solar system is essential for maximizing energy efficiency and reducing electricity bills. The WEM3050T, a 3 phase energy meter from IAMMETER, offers an affordable and easy-to-use solution for solar monitoring.

 

This guide will walk you through the quick and simple process of setting up the WEM3050T for real-time solar power monitoring.

 

What You Need for Solar Monitoring Setup

WEM3050T Wi-Fi Energy Meter

CT clamps (included in the package)

Access to your main electrical panel

2.4 GHz Wi-Fi network

Optional: IAMMETER Cloud account (IAMMETER provides 3 months of free cloud service for the WEM3050T)

WEM3050T

 

Step 1: Install the WEM3050T for Solar Monitoring

Turn off the main power to ensure safe installation.

Connect the CT clamps (assuming both your grid and inverter outputs are unidirectional):

Clamp 1: Connect to the grid-side phase (e.g., L1).

Clamp 2: Connect to the solar inverter output (e.g., L2).

Clamp 3: Optional — use for a second inverter or household load (e.g., L3).

Connect the WEM3050T voltage input wires to the same phases you're monitoring.

Power on the meter.

Make sure the CT clamps are correctly oriented — the arrow should point in the direction of current flow (from source to load).

Step 2: Connect WEM3050T to Your Wi-Fi Network

After powering up the WEM3050T, connect your phone to the device’s hotspot (SSID: IAMMETER_xxx).

Open a web browser and navigate to http://11.11.11.1.

Enter your home Wi-Fi SSID and password.

Save the settings — the meter will reboot and connect to your network.

Introduction Single phase WiFi energy meter (WEM3080) is a Din rail, bi-directional, Wi-Fi energy meter/Wi-Fi electricity monitor. It is highly integrated power meter with Wi-Fi module embedded, which measures the data, such as single-phase AC voltage, current, power etc, and transmits them to cloud via WiFi network. smart meter wifi connection by one-key setup. With that, you can easily track, monitor and analyze your energy consumption in your home, company or factory in real-time. If you have a solar PV system, this meter can also help track the entire energy flow of the system. The system tells how much energy your solar system is producing, how much excessive energy are exporting to the grid or how much your loads are consuming from grid or your solar system. With open API, you can monitor the data locally via LAN or upload the data to your own server. Standard Package No. Item Qty Remark 1 Wi-Fi Energy Meter 1 Wi-Fi Module Embedded 2 Split-core Current Transformer 1 150A or 2...
