It is necessary to first design a general schematic of necessary components, then a pcb board based on that using KICAD, then a prototype by ordering and building components. Relevant Skills and Experience I am experienced in electrical design through KICAD and currently study/work in Mechatronics Engineering in San Jose State University. I have worked in the AGV industry and Robotics electronics. Proposed Milestones $500 USD - Initial Design including wire diagram and general BOM $400 USD - Specific Detailed BOM and PCB design with output files for manufacturing $211 USD - Python programming, testing of sample boards, and more.

Hi there, I'm interested in your project. I made similar solar charge controller including MPPT algorithm and 5V/3A smps to charge cellphones. I found that your project is similar to what I did before. Only one thing is different is I'm using mikroC in most of the case. If it is ok, I can help you.
