The two power controllers switch on at different times. Starting from the
dashed lines, the dispersion of energy takes place symmetrically to the left
and right (see arrows). For as long as the total output level of the two devices
is below 100 %, two device currents in a single phase are prevented from
overlapping. The next power level in the network is not started until the total
output level exceeds 100 %.
A
If one power controller performs a restart when the configuration
level is exited, it no longer operates synchronously with the others.
All power controllers have to be switched on again simultaneously
via a joint main switch!
