2.1 Appropriate Usage
The Sunny Central is a solar inverter. It is used to feed solar energy converted by solar modules using
photovoltaics into a low- or medium-voltage grid.
Principle of a grid-connected solar power system with a Sunny Central
Sunny Central
The standard Sunny Central is equipped with a low-voltage transformer and feeds into the low-voltage
grid.
Sunny Central LV
The Sunny Central LV feeds into the low-voltage grid. It is suitable for the connection of modules with
low voltage.
Sunny Central HE
The Sunny Central HE is a high efficiency photovoltaic inverter. It is not equipped with a low-voltage
transformer. The Sunny Central HE requires a suitable external medium-voltage transformer through
which it can feed into the grid.
Sunny Central MV
The MV stations are medium-voltage stations. In an MV station, two Sunny Central HEs feed into a
shared medium-voltage transformer. The Sunny Central MV feeds into the medium-voltage grid.
