Hi developers,
Multi RS Solar, dual tracker, 1.16 beta2 firmware.
During sunset period, when the light is at the border of turning MPPTs off, randomly, the ACDC fan starts for about 10 seconds at full throttle.
Some days it can happen multiple times, some days not at all.
It happens, as I've said, only when MPPTs are "turning off", because the "sun icon" in the display's upper right corner is intermittently, quickly and randomly showing on and off.
Also, in the same time, the voltages from the PVs are randomly and quickly jumping in the 60-150 volts range.
Maybe some calculations on the trackers power, with these jumping values, lead to some BIG values that warrant this fan turning on full throttle?
Can an hysteresis be implemented on the MPPTs functioning, especially on sunrise and sunset?
Or improved somehow?
Thank you!
LE1: It happens on the morning too when MPPTs are turning on. See below first answer with some video.
LE2: It doesn't happen on 1.15. See below second answer.
