Heat output

Consider the heat dissipation ratings of equipment to determine cooling requirements. Additional

equipment may be required.

Electrical requirements

Load Batteries fully charged Batteries charging

100% 6,345BTU/hr 9,346BTU/hr

75% 4,759BTU/hr 7,946BTU/hr

50% 3,172BTU/hr 6,360BTU/hr

Note 1: Batteries fully charged is a continuous rating; battery charge time is 3 hours,

maximum.

Note 2: Charging losses are based on 3000W, 90% charger electronic efficiency, and

80% battery charging efficiency.

Note

The heat output is higher while batteries are charging. Under normal operating

conditions, battery recharging periods are infrequent.
