Micro Inverter Grid Tie Simulator Kit with ESP32 + LED
Micro Inverter Grid Tie Simulator Kit with ESP32 & OLED – SPWM Sine Wave Generation & Real-Time Power Analytics
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a working grid-tie inverter simulator that generates clean 50 Hz sine wave using sinusoidal pulse width modulation on ESP32, drives a MOSFET H-bridge, and monitors output voltage and real power with INA219 precision sensor. Ideal for school science exhibitions, B.Tech capstone projects, or understanding how solar inverters synchronize to the grid—without the risk of high-voltage grid connection.
What You'll Build
A complete bench-top micro inverter that converts 12 V DC into a 50 Hz sine wave, displaying live voltage, current, and power on the 0.96-inch OLED. You will assemble the H-bridge with IRF540N MOSFETs, generate SPWM signals from ESP32, and use ZMPT101B to verify output waveform quality. The system demonstrates the core principle behind grid-tie inverters: synchronized AC generation with real-time feedback.
What You'll Learn
- Generate sinusoidal PWM signals with adjustable modulation index and frequency on ESP32
- Design and drive an H-bridge circuit using IRF540N MOSFETs for DC-to-AC conversion
- Measure AC voltage and current with INA219 and ZMPT101B sensor modules, and calculate active power
- Debug power electronics prototypes using the OLED display and serial monitor, interpreting SPWM waveforms

Who This Kit Is For
CBSE Class 11–12 students preparing a physics working model on AC generation; B.Tech ECE/EEE students building inverter prototypes for mini-projects or Smart India Hackathon; ATL Tinkering Labs and IIT/NIT/VIT learners exploring renewable energy integration. If you need a hands-on demonstration of how a modern grid-tie inverter works at the signal level, this kit delivers a complete educational platform.
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?
Your kit includes a QR code that unlocks a dedicated AI companion. It knows this exact project, can walk you through each connection, and is backed by WhatsApp support if you need human help.
Does this inverter actually connect to the grid?
No, it is a simulator that demonstrates grid-tie principles. The output is a low-power 50 Hz sine wave intended for measurement and learning, not for feeding power into a mains socket.
Can I power a small appliance with it?
The output power is limited to a few watts, sufficient for an LED or small resistive load during testing. It is not designed to run household appliances.
Do I need an oscilloscope or extra tools?
No oscilloscope is required. The INA219 and ZMPT101B provide voltage/current data on the OLED. However, you can connect an oscilloscope if you wish to view the raw SPWM waveform. The included soldering iron and solder are adequate for all prototyping boards.
SPWM on ESP32 drives H-bridge to produce clean 50Hz sine. INA219 measures output quality and power.
