Hello, I'm working on a school project where I connect a boost converter to a solar panel to track the MPP and charge a battery. When i use an arduino paired with a INA219(Voltage and current sensor) to do a duty sweep to check where my MPP is, I get a straight line where my current increases linearly with my voltage. I think this was supposed to decrease at some point? And give me a good looking IV curve? Something like this? http://www.seaward-groupusa.com/userfiles/image/landing-pages/curve-tracing/solar-pv-iv-curve-tracing-diagram-2.jpgAlltough this is not working, the MPP tracing code seems to be doing fine. (I have the ina219 spit out voltage and current, and duty going up/down until finding the best power output (V*I)Im not sure this project is even viable. The guidding teacher seems to now even less about the subject than I doIs this the right place to ask the question? I looked for more eletronics guided subreddits but couldnt find any. via /r/DIY https://ift.tt/2GH3ghN
