I am B Tech ( Electronic and communication engineering) student at DDU Nadiad.I see that you are looking for a freelancer to develop a grid-tied solar inverter system. I have extensive experience in C programming and can handle this project with ease. My skills include C language and C++ language, which will help me to develop the system faster and efficiently. Moreover, I am well-versed in Word, Excel, Power Point which will be extremely helpful in creating effective presentations to showcase the accuracy of my work.
I understand your concern regarding the synchronization of the grid-tied solar inverter system with the output displayed on an LCD display. To eventually achieve this goal, I believe it will be necessary to modify your circuit and C code so that they can run the output on an LCD display synchronized or not. This can be done easily by me as I have extensive experience in xc8 compiler and pic18F4520. Additionally, I am willing to provide sample programming for 7 segments so that you can compare the output with your expectations.
