Enjoying nice regular sun here today, but I am noticing that my MPPT is regularly going through a period where it is dropping and re establising its output. Zoomed out and more zoomed in screen shots attached.
Clearly part of its operation but would be nice to understand what its doing and why it happens?
Anyone know?
This is normal, and is how the MPPT function searches for the optimum voltage to pull power out of the solar panels. Every 10 minutes it scans the available voltages to be sure it is running at optimum. Optimum voltage can change with partial shading, cloud cover, or time of day.
Many thanks, I did check the frequency and as you say, it is every 10 minutes that it has its cycle.
