Hello, I can develop the robust C firmware for your 3.5 kW single-phase on-grid inverter. Combining electrical engineering expertise with embedded C and C++ programming, I will implement a responsive phase-locked loop ensuring phase error stays within ±1°. I will structure modular, interrupt-safe routines for real-time sampling of current and voltage within ±2% accuracy. Furthermore, I will implement fast fault-handling logic to execute safe inverter shutdowns in under 100 ms upon grid loss or over-limit events. You will receive clean source files, build scripts, and a clear design document. Best regards,

I would be glad to take the opportunity to develop the C firmware for your 3.5 kW single-phase on-grid inverter. I can structure the firmware into clean, modular, maintainable modules covering grid synchronization/PLL, real-time ADC measurement and power calculations, protection monitoring, fault handling, and controlled shutdown. I will work from your MCU pin-map, schematics, and SDK, using interrupt-safe routines and clearly documented control logic. The design will target your stated requirements for ±1° phase-lock accuracy, ±2% measurement accuracy after calibration, and rapid fault response within 100 ms. Deliverables will include complete C source/header files, the IDE/toolchain project, design documentation covering PLL, measurement mathematics and fault logic, plus a flash-ready binary and bench-testing guide. I can also support iterative testing using your scope captures and measurements to tune and validate the control loops and protection thresholds. Give me one opportunity to handle your project. I assure you of dedicated, accurate, and professional work with clear communication throughout.
