General
General The Fronius Power Control Box limits the maximum output power of a
photovoltaic system in accordance with power supply company stipulati-
ons.
As and when required, the power supply company can use a ripple control
signal receiver to set 4 different limit levels.
The Fronius Power Control Box forwards the incoming information along
the Fronius Solar Net to the inverters on the photovoltaic system, which
then independently adjust the output power as appropriate.
Maximum
output power
limitations The power supply company may limit the maximum output power at the
following levels:
Level Limitation Description
1 100 % no power limitation; energy is fed into the grid in
optimum light conditions and at the maximum
possible output power of the inverter
2 60 % power limitation at 60 %; energy is fed into the grid
in optimum light conditions and at 60 % of the
maximum possible output power of the inverter
3 30 % power limitation at 30 %; energy is fed into the grid
in optimum light conditions and at 30 % of the
maximum possible output power of the inverter
4 0 % power limitation at 0 %; no energy is fed into the grid
