The own solar powerstation
The FRONIUS IG central inverters are suitable for pv systems starting
with an AC output power of 24 kW and work with a completely new
system configuration. There is not only one power stack converting
the electricity but also 9, 12 to 15 printed circuit boards that share
the work, depending on the output class.
The reason for this is that it is well-known that the energy yield
increases in part-load areas if smaller power stacks are operated at
higher capacity. Therefore, every FRONIUS IG central inverter works
with several smaller power stacks that switch on or off completely
automatically depending on irradiance so that they can always deliver
maximum power.
