Three Phase Energy Analyser Kit with Arduino Mega
Build a Three-Phase Energy Analyser with Arduino Mega – Track Per-Phase kWh and Imbalance
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine monitoring the energy consumption of your lab, workshop, or campus building across all three phases, spotting imbalances before they cause equipment damage. This kit lets you assemble a professional-grade energy analyser using three PZEM-004T modules and an Arduino Mega, displaying live data on a crisp colour TFT.
What You'll Build
You will build a fully functional three-phase energy analyser that tracks voltage, current, power, and total kWh for each phase independently. The 1.8-inch TFT screen shows real-time readings, calculates phase imbalance percentages, and logs cumulative energy usage – all in a DIN rail enclosure suitable for permanent installation.
What You'll Learn
- Interfacing multiple Modbus-RTU sensors (PZEM-004T) with Arduino Mega
- Programming a TFT colour display with live data dashboards
- Calculating three-phase imbalance metrics and total energy consumption
- Assembling and soldering a mains-rated monitoring circuit with proper isolation

Who This Kit Is For
This kit is ideal for CBSE Class 11-12 students working on physics or electronics investigatory projects, as well as B.Tech ECE/EEE students tackling academic or Smart India Hackathon challenges. ATL Tinkering Lab facilitators and hobbyists from IIT, NIT, VIT, or BITS will find it a ready-made solution to demonstrate real-world energy monitoring with professional-grade accuracy.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code inside your kit to access the AI build companion, which can walk you through every connection and code block. If you need a human touch, send a photo on WhatsApp and we'll help within the day.
Is this kit safe to connect to mains electricity?
Yes. The PZEM-004T modules use built-in current transformers and voltage isolation, and the DIN rail enclosure keeps high-voltage wiring fully enclosed. Always follow the included safety guide and disconnect power before assembly.
Can I log data to a computer or SD card?
The Arduino Mega can be easily extended to log data via serial to a PC or add an SD card module (not included). The AI companion includes optional code snippets for serial data export.
Does the display show total consumption or per-phase only?
The TFT shows per-phase voltage, current, power, and kWh, plus a calculated total kWh sum and a real-time phase imbalance percentage, making energy auditing straightforward.
Three PZEM-004T measure per-phase kWh. Arduino Mega aggregates and shows imbalance on TFT.
