Schematic of the Fronius PV-Genset solution
Considerations in designing a PV-Genset Solution
− In a typical configuration the Solar controller is controlling the system in a way that the PV-
Genset is operating on at least 30% of its nominal power (configurable)
− The Solar controller is capable of adjusting the PV-power in a very fast way (depending on the
communication chosen with a reaction time of <1sec and a time constant of <1sec).
− Nevertheless, in the extreme event of immediate disconnection of a load larger that the
operating power of the PV-Genset (e.g. >30%) (see in Figure 2 at time 11:07:19) for a very
short time reverse power into the PV-Genset is possible.

ypical PV-Gensets do not have any problem with this short time behaviour, but Fronius
T
cannot guarantee this for all genset suppliers. If the PV-Genset has some kind of additional
revers power protection and the disconnection of the PV-Genset shall be avoided the system
designer has to take measures to protect the system form unwanted disconnections.
