ESP32 Hybrid Energy Monitor Kit - Solar Wind Grid Control
Master Renewable Microgrids: ESP32 Hybrid Energy Monitor with INA219 Array & Dispatch Logic
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Energy management for renewable systems isn't just about measuring volts and amps anymore-it's about making intelligent decisions that cut grid usage and lower bills. With this kit, you'll assemble a compact monitoring station that simultaneously tracks power from solar, wind, battery, and grid using four INA219 sensors, then program the ESP32 to calculate which source delivers the lowest cost per watt-hour right now. Perfect for final-year B.Tech projects, Smart India Hackathon energy challenges, and anyone wanting to understand the brains behind smart microgrids in India's rapidly evolving power landscape.
What You'll Build
You'll construct a fully functional hybrid energy monitor that shows live power flows on a 1.8-inch TFT colour display and logs timestamped data to a microSD card. The ESP32's firmware runs an optimised dispatch algorithm-if solar and battery are sufficient, the grid is disconnected; if wind peaks, it takes priority. The enclosure and wiring are up to you, but every component is validated to work together, so your first reading appears within hours, not days.
What You'll Learn
- Interface four INA219 current sensors across a single I2C bus using a TCA9548A multiplexer-essential for multi-source energy monitoring
- Capture accurate voltage, current, and power for solar, wind, battery, and grid simultaneously, with real-time clock and SD card logging for later analysis
- Design an ESP32-based decision engine that selects the cheapest energy source based on live thresholds and logs the switch events
- Build a graphical dashboard on a 1.8in TFT that overlays multi-source power bars, letting you visualise how hybrid systems behave under changing loads

Who This Kit Is For
This advanced kit is tailored for final-year B.Tech students in ECE and EEE who must demonstrate a working renewable energy prototype. It's equally valuable for Smart India Hackathon teams tackling grid-integration themes, and for research groups at IITs, NITs, and VIT needing a reliable multi-source measurement platform. The complexity assumes prior experience with Arduino/ESP32 coding and basic soldering, typical for 18-21-year-olds in India's engineering stream.
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?
The AI companion provides real-time wiring checks, code snippets, and sensor calibration steps. If you still need help, our WhatsApp support team responds within a few hours, often with photos of a functioning prototype.
Can I add a wind turbine input if the kit only includes a solar panel?
Absolutely. Each INA219 can monitor any DC source up to 26V. Connect your wind turbine's rectified output (within that voltage) to one of the available sensor channels, and the AI companion will show you how to label it in the dashboard code.
Does the kit come with the dispatch algorithm already programmed?
The included SD card contains a ready-to-flash firmware, and the AI companion guides you through uploading it. You can also open the source code to tweak thresholds-ideal for custom hackathon requirements.
How accurate are the INA219 readings for a small 2W solar panel?
INA219 modules achieve �0.5% current measurement accuracy, even at milliamps. With a 0.1-ohm shunt, you'll get reliable power readings for panels as low as 0.1W-more than sufficient for your solar tests.
Solar, wind, battery and grid all monitored by INA219 array. ESP32 calculates optimal dispatch strategy.
