Solar Hybrid Inverter Prototyping Help
Budget: ₹10,000 – ₹20,000 INR
I am building a new solar-hybrid inverter around an Infineon reference design and need an experienced technical advisor who can work with me on-site in Bangalore, part-time, through the entire prototype cycle. Your guidance is required across hardware design, firmware development, hardware fabrication, integration and final testing.
Most of the base schematics and application notes from Infineon are in hand; what I need now is a sharp eye and skilled hands to adapt those documents to my exact power ratings, oversee PCB layout iterations, supervise fabrication, bring the boards up safely, write and debug the control firmware, and validate the finished prototype under load. Expect plenty of hands-on lab work—oscilloscopes, power analyzers, thermal cameras, rework stations—plus code reviews and field tests on my roof array.
Key tools and concepts you should be comfortable with include: Infineon CoolMOS and EiceDRIVER devices, XMC microcontrollers, embedded C/C++, PSIM/SPICE simulations, MPPT algorithms, inverter PWM control, PCB thermal design, and safety-compliant high-voltage testing.
Deliverables (to be produced collaboratively with me on site)
• Updated schematics and layout notes reflecting our custom requirements
• Bootable, documented firmware covering MPPT, inverter control and protections
• A fully assembled prototype that starts up reliably, hits its target efficiency and passes functional tests at rated power
• Concise test reports and a short hand-over document so production can follow
Availability of two to three days a week for at least the next six weeks would be ideal, though I can be flexible for the right expert. If you thrive on tackling real hardware problems in person and enjoy seeing a design go from reference sheet to humming inverter, let’s talk.
