Hi,
I'm working on project which includes INA219 for sensing solar panel voltage and current. I have found other threads discussing on this matter but couldn't get answer I'm looking for. Instead of using any battery, I'm only looking to calculate current and Voltage from solar panel using INA219. As i know connections and read all forums related to this topic, I'm unsure how to connect Vin- to load. Should i use resistor as load to calculate current or can i bypass it by directly connecting Vin- to solar panel.
My solar panel typical Voltage is 5.5V whereas typical current is 170mA. I'm not charging any battery so unsure what type of load to use as I only need to calculate power at end through sensing voltage and current.
Thanks
