l 24 VDC operating voltage:Depending on the operating state of the
Generator Set 150 kW and the charging state of the battery set, the
24 VDC operating voltage can fluctuate between 22.8 VDC and 28.2
VDC: The higher value (28.2 VDC) occurs when the battery set is
charged and is being buffered by the generator. The lower value
(22.8 VDC) occurs when the battery set is discharged and the gen-
erator is idle. The voltage may drop below this value at tempera-
tures below 32 oF (0 oC), and/or at high currents (e.g. during start-
ing).
