Customer Reviews:
Beware of the 60 +/- 4 Hz frequency specification October 19, 2008
Tennyson Lee (Rocklin, CA United States)

Several of the Xantrex inverters including this one have much looser frequency specs compared to the last generation of inverters which were typically 60 Hz +/- 0.01%. Many of the current crop of these inverters have 60 +/-4 Hz which is 60 Hz +/- 7%. To be fair, I've noticed a number of inverters made by other companies also have relaxed this spec. I measured the output frequency of several models and found their outputs to range from 58 Hz to 64 Hz. I didn't test to see if the frequency changed with temperature, input voltage, load, or other other factors. I suppose the reason for this change in specs is that these manufacturers are now cost cutting to the extent of eliminating a 30 cent quartz crystal. The frequency variation is most likely to cause problems (speed changes and overheating) in devices with AC motors, but it will also cause inaccuracies in devices that use the AC line frequency for timing purposes.
