Hello,
I'm using the test file for the INA3221 to see if the SunAirPlus is working, and the voltage of the solar panel registers as 0 when it's connected. The red LED next to the solar cell port is also not lighting up. However, the Pi is able to run on power from the battery and if an AC adapter is plugged in. Any clue as to why that might be the case?
The solar panel is 6V 3.5W from Voltaic. Also as a test the panel is only powering the RPi 3B+, so there is no I2C mux or other sensors attached.
