AliExpress MPPT vs PWM Solar Charge Controller. Which One is Better? In-Depth Test & Data Analysis

Описание: MPPT vs PWM Solar Charge Controller – Which One Should You Buy? In this video, I compare an MPPT solar charge controller vs a PWM charge controller with real tests, data logging, and in-depth analysis!

📌 What’s Covered in This Video?
✅ MPPT vs PWM – Price, Efficiency & Performance Comparison
✅ Charging & Discharging Tests using an accurate Arduino-based sensor setup
✅ Live Data Logging with INA219 & real-time tracking using a DS1307 RTC module
✅ Custom Python Data Visualization for trend analysis
✅ Which solar charge controller handles battery charging more efficiently?
✅ Is the MPPT charge controller worth the extra cost?

For this test, I simulated a solar power setup by using a fixed voltage charger instead of solar panels to ensure consistent input conditions for accurate results. Both controllers were tested with the same battery, same load, and same environment to compare charging cycles.

📊 Data Analysis & Key Takeaways:
⚡ MPPT Solar Charge Controller: More stable voltage & efficient power delivery
⚡ PWM Solar Charge Controller: More fluctuation & inconsistent charging
⚡ Battery Performance: Voltage drop & discharge behavior over time
⚡ Power Consumption: Measuring amp-hours & energy efficiency

The MPPT controller handled load discharge much better compared to the PWM controller, making it a clear winner in maintaining stable power flow after the battery reached its threshold.
