Hi,
I've just noticed that last few days/weeks, the mppt behave strangely. In previous months, when the day was sunny, the PV Yield graph shows almost consistent line. However, last few days/weeks, it looses power for a second and then goes back to normal. For example today was very sunny day, with no clouds at all, and sometimes when I checked the VRM app, I saw that the power dropped for a second or two. Any idea what might cause that?
Thanks,
Jakub
P.S.: sorry, cannot add pictures, not sure why...
