EcoWatt – Smart SolarInverter Monitoring & Control System

Designed and developed a production-ready IoT solution for real-time solar inverter monitoring featuring:

Security & FOTA: Triple-layer upload protection (nonce validation, HMAC-SHA256, AES-128-CBC) + Secure firmware updates with RSA-2048 signatures and automatic rollback

Data Compression: Adaptive algorithm selection achieving 85% data reduction (140→21 bytes) through intelligent real-time compression tournament

Power Management: Peripheral gating reducing consumption by 10-20mA, with production support for CPU frequency scaling, light/deep sleep modes

Remote Control: Bidirectional command queue enabling real-time device configuration, parameter adjustment, and sub-second command latency

Live Dashboard: Professional React interface with real-time visualization, power analytics, device monitoring, and fault injection testing

Modbus Support: Ring buffer architecture supporting both Modbus RTU (production) and WiFi simulation (development)

Production Quality: 30+ test suites, fault injection framework, security validation with comprehensive testing
