PD 9280 Specs:

So what does that all really mean? 13.6 x 80 = 1088w. They claim at least 80% efficiency. 1088/1300 = 83.6% so they are doing the specs at 13.6, not 14.4
At 14.4v, 14.4 x 80 = 1152w output, and at 83.6% efficiency, input would be 1378w
BUT as discovered in the other thread, the PF correction is 0.7 and you use that for input. 1152 x 100/70 = 1645VA drawn from the AC power source.
1645VA requires 12 wire and 20a CB by NEC rules for appliance left on more than 3 hours.
