@hayteekeys

HI, KINDLY READ THROUGH MY PROPOSAL I will deliver your production-ready single-phase grid-tie solar inverter: refined schematics & fully routed PCB, complete deterministic Embedded C firmware (MPPT, grid-sync, anti-islanding, protections), full system integration, and verified test results — built directly on your existing prototype. MY APPROACH ✅ Phase 1: Review & tighten existing schematics/PCB for manufacturability, update power stage, DC-link, current sensing, grid-sync hardware and BOM. ✅ Phase 2: Complete Embedded C control loops, protection logic, comms, real-world testing (efficiency, THD, anti-islanding) and integration guide. ✅ Provide milestone reviews and final handover package. RELEVANT PROJECTS • 2.5 kW single-phase grid-tie solar inverter (prototype to production: full PCB routing, Embedded C firmware, MPPT/grid compliance testing — delivered tested unit) DELIVERABLES • Updated schematics + complete routed PCB files • Comprehensive BOM with manufacturer PNs & alternates • Well-commented Embedded C firmware source (build-ready) • In-circuit test plan + recorded results (efficiency, THD, protections) • Brief manufacturing integration guide QUESTIONS 1. Which MCU/DSP and toolchain are used in the current prototype? 2. Can you share the existing schematics, partial PCB & any test data now? 3. Target power rating and preferred first milestone date? Ready to start immediately.

My understanding of power electronics not only allows me to design hardware efficiently but also optimize firmware for resource-constrained controllers in Embedded C. This proficiency is critical when dealing with a high-stakes project such as designing a solar inverter that must meet precise utility specifications for grid synchronization. Having significant experience controlling initiatives within tight tolerances, I am confident in my ability to adhere to deterministic timings while shaping sine waves. Moreover, my previous projects have demanded meticulous attention to detail in aspects like efficiency, THD, and protection triggers - precisely what you need for this assignment. I am well-versed with developing in-circuit test plans and recording results accurately, ensuring rigorous verification of designs under real-world conditions. Ultimately, I'm an engineer who thrives on challenges that push me to deliver exceptional quality across all facets of an assignment- be it refined hardware designs or thoroughly-tested code. Working on this project would be an exciting endeavor for me as it falls right within my passion and expertise!

Hi, I'm Akshay, an Electronics Systems engineer and founder of ZiroEDA, incubated at IIT Madras. We work on AI accelerated PCB development , basically Custom circuit boards, designed and manufactured with AI but Every design is reviewed by experienced electrical engineers to ensure safety, compliance, and manufacturability before production. so that we can deliver board faster and way more cost effective. I've read the brief carefully. This is a full stack power electronics engagement, will love to extend it. What I bring: Power electronics experience with grid-tied inverter topologies, SPWM, and closed-loop control Embedded C on MCUs with deterministic ISR timing PCB design with high-frequency layout discipline (gate loops, DC-link decoupling, current sensing) AI-assisted tools for faster schematic validation, BOM, and DRC without compromising quality Approach: 1. Review schematics/prototype and identify protection and control gaps 2. Refine PCB for manufacturability and switching performance 3. Complete firmware (MPPT, PLL sync, SPWM, protections) 4. Deliver BOM, test plan, and integration guide Happy to jump on a quick chat to review your prototype and start right away. Best, Akshay Founder, ZiroEDA | IIT Madras NIRMAAN

Hi, I can help complete your single-phase grid-tie solar inverter from the existing prototype stage through refined hardware, firmware completion, and integration testing. I understand this is not just PCB cleanup or basic Embedded C work — the critical areas are grid-sync stability, deterministic control timing, MPPT behavior, current sensing accuracy, protection logic, anti-islanding safeguards, THD, efficiency, and manufacturable hardware design. My approach would be to first audit your current schematics, partial PCB, control algorithms, MCU/DSP choice, sensing circuits, gate drive, DC-link, and protection paths. Then I’ll refine the hardware for fabrication, complete the Embedded C firmware, and validate each subsystem against measurable test points before full integration. I can deliver updated schematics, routed PCB files, BOM with alternates, commented firmware, test plan/results, and a clear integration guide for manufacturing. Please share the current schematic, PCB files, controller details, and grid compliance targets so I can confirm the exact milestone plan. Best regards Ankit

You’re very close—but this is exactly where most inverter projects fail: the last 10% where hardware, firmware, and grid compliance have to work perfectly together. Small timing issues, sensing noise, or protection gaps can turn a working prototype into an unreliable product. I can take ownership of that final stretch and bring it to a production-ready state. I’ll refine your schematic and PCB for manufacturability and robustness, then complete the Embedded C firmware with tightly controlled timing for stable grid-sync, clean sine output, and reliable protection handling. On top of that, I’ll validate the full system—DC link, power stage, control loops, and communication—under real-world conditions to ensure efficiency, low THD, and compliance with grid requirements. You’ll get clean fabrication-ready design files, a solid BOM with alternates, well-structured firmware, and clear test results plus an integration guide your manufacturing team can actually follow without friction. If you want this inverter finished right—with no surprises at production or deployment—message me now and let’s lock in the milestones and get it across the finish line.
