2.1 Appropriate Usage
The Sunny Central is a PV inverter. It allows photovoltaic solar energy from PV modules to be
converted and fed into a medium-voltage grid.
The Sunny Central models SC 100LV, SC 125LV, SC 150, SC 200HE, SC 200, SC 250HE, SC 250,
SC 350HE, SC 350, SC 500HE and SC 560HE are equipped with the new grid security
management function. Further information on grid security management is provided in Section
3 ”Grid Security Management” (page 14).
Principle of a grid-connected PV system with a Sunny Central
Sunny Central
The Sunny Central is equipped with a low-voltage transformer, and feeds into the low-voltage grid.
Sunny Central HE
The Sunny Central HE does not have its own low-voltage transformer. It requires an adapted external
medium-voltage transformer via which it can feed into the grid.
Sunny Central LV
The Sunny Central LV feeds into the low-voltage grid. It is suitable for the connection of PV generators
with low voltage.
Sunny Central MV
The MV stations are medium-voltage stations. In an MV station, two Sunny Central HE devices feed
into the medium-voltage grid via a shared medium-voltage transformer.
