Fuel consumption GrossNote: All figures in the tables below are based on gross mechanical output, for fuel consumption based on electrical output of the generating set contact your OEM.
Battery capacity is defined by the 20 hour rate at 0°CThe oil specification should be for the minimum ambient temperature as the oil will not be warmed by the immersion heaterBreakaway current is dependant on battery capacity available. Cables should be capable of handling transient current which may be up to double the steady cranking current.
