A \"generator\"(not alternator)  is rated at 30 amps , so I think it works like this..... 30 amps x 12 volts = 360 watts( if it's working perfectly)

your four 55 watt lights = 220 watts  plus anything else you have on..... wipers , stereo , ignition , stock head lights and running lights etc etc
 You could be close to the edge.
I'm not 100% sure this the correct calculation , someone correct me if I'm wrong.

Your calculations are correct.  Keep in mind that most likely the \"30A\" rating on the gen is Peak output.  That would be flat out going hard.  Now you slow down and the rev's go down... you won't be getting Max rating anymore.
