Hybrid solar power system integrates photovoltaic panels, battery storage, and hybrid inverter with real-time IoT supervision via ESP32 microcontroller. Solar panel feeds hybrid inverter while battery provides backup power through DC-DC converter, with voltage and temperature sensors monitoring battery health. ESP32 transmits telemetry to ThingSpeak cloud platform, enabling remote monitoring through Flutter mobile application for system performance tracking. This architecture demonstrates best practices for renewable energy systems with predictive maintenance capabilities through continuous sensor data collection. Fork this diagram on Diagrams.so to customize component specifications, add additional sensors, or adapt the monitoring stack for your solar installation.
