The indicated power on the x axis complies approx. 6.2 kW per phase.
In consequence you should install only one Sunny Mini Central 5000/6000 per
phase. To install a plant with a higher power that does not stop feeding because of
AC over voltage, you should check the connection conditions of the Sunny Mini Cen-
tral 5000/6000 (e. g. by using a cable with a higher cross-section).
Example
The grid voltage without feeding averages 230 V.
The grid impedance at the connection point averages 1.2 Ohm.
