Naja, bei mir ging der nicht auf Störung, sondern lief einfach mit seiner Nennleistung weiter.
Wird hier übrigens auch von Victron so erklärt und beschrieben.
Zitat Fa Victron:
Oversizing a PV array
Oversizing a PV array means installing more peak power (Wp) than the maximum charge power of the chosen MPPT charge controller. A common reason to oversize is to cater for winter time when the sun is not as powerful.
The MPPT solar sizing calculator will allow for a 130% PV array oversizing when recommending a charge controller.
The design logic is that panels RARELY spend much time at their peak rated output capacity, only maybe an hour in the middle of a sunny day. The rest of the time they are derated below their spec maximum, and less than the maximum capacity of the charge controller.
Some installers don’t like to do this however, and will override it so that the panel output is never constrained. The best choice will depend on the installation, and may take into account a limited roof area, or limited solar window (due to shading).
Another reason to oversize panel to charge controller capacity is that PV panel output degrades over time, as they get soiled, dirty, PID, etc.
Generally total energy harvested from a 130% panel oversizing results in less than 1% annual energy loss.
