This is what I got from AlienBees.com:
"The AlienBees monolights are designed to operate only from 110 to 130 Vac 50/60 Hz power sources. When operated at 50 Hz the recycle times will be some 20% longer than as specified for 60 Hz operation. The units are rated at 6 amps average. At full power, the lights may briefly peak at nearly 18 amps input current at the very beginning of the recycle period. The units will draw less average current if the flash power is set for lower output and the modeling lamp is off. Depending on the model lamp rating, and the model lamp power setting, the units require approximately 1 to 2 Amperes to illuminate the model lamp and maintain the flash charge while awaiting the next flash.
A portable AC generator is rated by continuous load output, peak output during maximum load, and whether or not its output is voltage regulated. For use with our flash units, a generator must supply at least 165 Watts per light, with continuous output. The output of the generator should be voltage regulated. Peak output should be at least 1040 Watts per light. The reason for this is that a generator cannot increase only its output current level. It must generate a higher output voltage level to accommodate peak power demands. If overloaded, a generator may produce a 'clipped' ac waveform, or apply an output voltage greater than 130 Vac to the flash unit(s). Over time this will damage the equipment. It is therefore good practice to have the generator able to provide over and above the combined maximum peak needs of the lighting setup.
The generator output should tie Earth (or System) Ground to Neutral. This should be done through a Ground Fault Interrupter (GFI) circuit breaker. (The GFI will open the circuit if voltage is present across Neutral and Ground. This is a safety feature to prevent accidental shocks.) If the generator does not have Earth and Neutral protected in this manner then the flash unit may sync erratically, indicating Neutral is 'floating' (not grounded) and ac voltage is present on the flash unitís housing. This is a potential shock hazard and must be corrected by adding an external GFI. Please check with a qualified technician and the generatorís manufacturer for proper procedures. This information should be obtained when purchasing the generator."
Will this info help you to tell me if the pack is workable?
