			<![CDATA[Modern inverters have to have a small THD (Total Harmonic Distortion) which should cover such issues, though I do note that the current flows seem to be odd enough to thoroughly confuse clip-on energy monitors:<br /><br /><a href="http://www.earth.org.uk/note-on-clip-on-power-meters-for-the-UK-REVIEW.html" target="_self" rel="nofollow">http://www.earth.org.uk/note-on-clip-on-power-meters-for-the-UK-REVIEW.html</a><br /><br /><a href="http://www.theregister.co.uk/2011/08/24/alertme_energy_monitoring_system_review/" target="_self" rel="nofollow">http://www.theregister.co.uk/2011/08/24/alertme_energy_monitoring_system_review/</a><br /><br />In principle someone is welcome to come round and plug their equipment into my house mains briefly to make sure that it doesn't get upset.
