Microgrid Island Mode Controller Kit with Arduino Mega + Relay
Automate Power Outage Response with the Arduino Mega Microgrid Island Mode Controller Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In Indian homes and labs, power cuts disrupt work and can damage sensitive equipment. This kit lets you build a controller that senses a mains outage within milliseconds, activates a battery inverter via relays, and then automatically cuts off non-essential loads so the battery lasts longer. You'll gain hands-on experience with real voltage sensing, relay logic, and energy management.
What You'll Build
You'll assemble a DIN-rail-mountable microgrid controller around an Arduino Mega. The ZMPT101B sensor monitors AC mains and triggers the 4-channel relay to switch to backup power. Two INA219 modules measure load currents, while the DS3231 RTC enables time‑based load shedding. An OLED displays live status and a microSD card logs every event — a complete, demonstrable prototype for engineering projects and competitions.
What You'll Learn
- Calibrate and read the ZMPT101B AC voltage sensor to detect outage with high accuracy
- Program Arduino Mega for real‑time relay switching and interrupt‑based monitoring
- Implement load shedding algorithms using RTC time and user‑defined priority levels
- Integrate INA219 current sensors to protect against overload and log energy data

Who This Kit Is For
This kit suits intermediate learners — CBSE Class 11‑12 students exploring applied physics, B.Tech ECE/EEE undergraduates working on power automation projects, and participants in Smart India Hackathon or ATL Tinkering Lab challenges. If you’ve built basic Arduino circuits and now want to tackle real‑world energy management involving AC mains, relays, and sensor integration, this project bridges the gap between theory and a deployable prototype.
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 to talk to the AI build companion, or message us on WhatsApp — we respond within hours with specific debugging steps for this project.
Does this kit work with my existing inverter?
Yes, the relay module can interface with any standard inverter that uses a low‑voltage control signal. Just ensure your inverter’s remote start matches the relay ratings.
Can I modify the load shedding logic?
Absolutely. The Arduino sketch is open and well‑commented. You can adjust the priority tables, add new sensors, or change timing rules to suit your specific backup strategy.
What if a part is defective?
We replace any component with a manufacturing defect free of charge within 7 days of delivery. Just contact support with your order details.
Detects mains outage via ZMPT101B. Switches to battery inverter mode. Manages load shedding by priority.
