The valid neutral-ground voltage for the TT grid mode must be less than 30 V.
The SUN2000-28KTL applies to medium-voltage and low-voltage power grids. If the
output voltage of the SUN2000 (three-phase, with a PE cable, 480 V) does not match the
power grid voltage, connect a transformer to adapt to the power grid voltage.
For example, if the SUN2000 is connected to a low-voltage power grid (three-phase, with
an N cable and a PE cable, 400 V), a transformer is required to convert the 480 V voltage to
the 400 V voltage.
