2 [Reserve Load-dependent start stop is performed in a way that a configured minimum
power] reserve power is maintained in the system. The reserve power is the total
generator rated power minus the total actual generator power.
If the reserve power falls below the threshold, another genset will be started.
If the reserve power is sufficient to stop one genset without falling below the
threshold, a genset will be stopped.
Generator load Load-dependent start stop is performed in a way that a configured maximum
generator capacity utilization is not exceeded.
If the generator capacity utilization exceeds this threshold, another genset will
be started. If the generator capacity utilization is low enough to stop one
genset without exceeding the threshold again, a genset will be stopped.
