3.2.2 AC Input Voltage and Grid Currents
The input grid currents depend on the operational point and the input voltage. As shown in
input grid currents are achieved at highest power and lowest voltage. Note that the grid currents also depend
on the impedance of the grid, therefore below values are only typical values.

Note 2: Values depend on impedance of grid.
3.2.3 Inrush Current
Various situations have to be considered for the inrush current. The controller has integrated inrush current
limiters, which limit the current during switch-on of the AC power. However, these limiters are not active if the
controller is not completely discharged
shows the inrush currents during these situations. It has to be
emphasized that these are absolute worst case currents measured with a rigid mains supply at highest input
voltage. In reality these inrush currents might be much smaller.
