(D) Isolation transformer (E) Power grid
In medium-voltage grid connection scenarios and non-low-voltage public grid connection
scenarios (industrial environment), the SUN2000 is powered by a dedicated power
transformer instead of connecting to low-voltage overhead power lines.
Supported Power Grid
The SUN2000-50KTL-M0 and SUN2000-60KTL-M0 support the following power
grid modes: TN-S, TN-C, TN-C-S, TT, and IT. The SUN2000-65KTL-M0 supports only
IT grid mode.
