A super converter to the 10% THD at full load, which is great and I've rarely seen in other converters. In other words, the sine wave is deformed also at full load only by 10%! Here we can say true sine wave .. I think the operation should not interfere with some device. In addition, the device has switched off when not equal to 1500W, it delivers in fact briefly more than 1700W. The 3000W are just tips, these I have not checked, but a vacuum cleaner with 1400W will surely demand a more than 3000W peak and also began. Even an asymmetrical loads (eg: if only one half-wave is used, hairdryer with 2 steps) drove the part without the battery to charge pulsing, like the do not know, but with other transducers that was always the case. Again, the sinus was still halfway respected, even if THD was already serve up some 20%. I'd buy it again.
