RATING DEFINITIONS
Standby
These ratings are applicable for supplying
continuous electrical power (at variable load) in
the event of a utility power failure. No overload
is permitted on these ratings. When used
at standby rating the alternator will be peak
continuous rated (as defined in ISO8528-3).
Prime Power
These ratings are applicable for supplying
continuous power (at variable load) in lieu of
commercially purchased power. There is no
limitation to the annual hours of operation and
this model can supply 10% overload power for
1 hour in 12 hours.
