HIOKI Power Quality Analyzer. Power to the property with all normal loads running: Total Harmonic Distortion: AC from Mains: 2.5% AC from Inverter: 2.3%   Virtually the same first 5 odd harmonics and all below 2.3%. The Inverter THD when isolated from Property, just Inverter THD, unloaded and loaded with a resistive load.. No Load: 0.9% THD    2.3kW:  0.6% THD. Almost all fundamental frequency, which is exactly what you want, the first and second odd harmonics are tiny, the third barely visible, nothing after the 3rd odd harmonic, and this tester reads out to the 37th harmonic. From memory, anything under 3% in a typical inverter is considered good enough. NOTE: This is measured on a 12kW Symmetrical Drive modulated WG Inverter. . Edited 2026-07-20 11:34 by KeepIS
