What Is IAMMETER: Energy Management Platform for Home, Business, and Industry

IAMMETER Quick Start Guide

(Your all-in-one guide to quickly start monitoring and optimizing your energy system)

1. What Is IAMMETER

IAMMETER is a Wi-Fi energy monitoring and management platform for homeowners, businesses, and industrial users. It not only tracks power usage but also helps customers optimize energy utilization — such as maximizing solar self-consumption and reducing electricity costs through smarter power management.

With IAMMETER, you can:

• Track power, voltage, current, and energy (kWh) in real time
• Monitor solar PV generation and grid interaction
• Use surplus solar energy for heating or EV charging
• Integrate with smart home and industrial control systems

Core Components

2. Identify Your Electrical System

Before installation, determine your electrical system type to select the right meter.

All IAMMETER meters support bidirectional measurement (import/export power), ideal for solar PV applications.

3. Three-Phase Meters Overview: Choose the Right Model for Your Needs

IAMMETER provides three types of three-phase Wi-Fi energy meters — WEM3080T, WEM3046T, and WEM3050T.
All of them share the same core capabilities:

• Bidirectional metering — measures both imported and exported energy
• Supports single-phase, split-phase, and three-phase (3P4W) systems
• Open communication interfaces: HTTP, Modbus/TCP, and MQTT

Although their measurement performance is similar, the target users, bundled accessories, and included IAMMETER-Cloud services differ across models.

Model	Recommended For	Cloud Service	Documents	Notes
WEM3050T	Home users, DIY installers, solar PV hobbyists	IAMMETER-Cloud Basic (Free)	Datasheet Quickstart	The package includes one meter and three split-core CTs (150A, 16mm). Can be upgraded to IAMMETER-Cloud Pro (optional, $60 / 5 years).
WEM3080T	Enterprise or advanced monitoring systems (up to 500A per channel)	IAMMETER-Cloud Pro (Included)	Datasheet Quickstart	The package includes one meter and three split-core CTs. Available CT options: 150A (16mm), 250A (24mm), 500A (36mm). CTs are shipped together with the meter and are not user-replaceable.
WEM3080TD (Three-phase, 3-wire)	Enterprise or delta (3-wire) systems (up to 500A per channel)	IAMMETER-Cloud Pro (Included)	Quickstart	Designed for three-phase, 3-wire (delta) systems. The package includes one meter and two split-core CTs (150A, 16mm).
WEM3046T	Commercial or industrial energy monitoring (supports 5A CT output)	IAMMETER-Cloud Pro (Included)	Datasheet Quickstart	The package includes only the meter, without CTs. Supports external 5A secondary CTs (e.g., 1000:5, 2000:5), allowing flexible high-current measurement.
WEM3046TE	Commercial or industrial monitoring (double-CT application)	IAMMETER-Cloud Pro (Included)	Datasheet Quickstart	The package includes the meter + one 5A split-core CT, which clamps on the secondary output line of the primary CT. Designed for dual-CT measurement scenarios.

Important Notes:

• All IAMMETER-Cloud Basic features are free and available to every user.
• Pro features (advanced reports, API access, data export, etc.) are included at no extra cost for WEM3080T and WEM3046T users.
• Only WEM3050T users need to upgrade manually if they wish to access IAMMETER-Cloud Pro features.

Summary:

If you are a home or solar PV enthusiast, choose WEM3050T — compact, affordable, and paired with IAMMETER-Cloud Basic (free forever).

If you are a commercial or industrial user, choose WEM3046T or WEM3080T — both come with IAMMETER-Cloud Pro included, providing advanced analytics and integration capabilities at no extra cost.
