Joe,
They claim:
60 Hz +- 0.16 Hz
120 VAC +-2%
2.1% THD (Total Harmonic Distortion)
All this from 1600 rpm up to 6000 rpm
At idle the efficiency is 85%
5 and 8 kW continous.
AC only and AC/DC versions, offering 200 amps @ 14VDC and 150 amps @ 28 VD
AND in the same time 26 amps @ 120 VAC for the 5 kW model..
They claim their 5 kW model outperforms the 7.5 kW Honda EX series
generators
2 patents
Size OD 12.2 inch x Width 5.085 inch
However, the Electronic Control Unit is a rather large box 19 x 10 x 8 inch
