| SR. NO | Existing Technology Based H-UPS | Kevin IGBT Based H-UPS |
| 1 | Not Pure Sine. Some distortion on pure tube light load | No distortion so Pure Sine wave |
| 2 | Efficiency approx. 70% at actualhouse hold Load.For 2.5Hrs backup you require 150Ah battery | Efficiency approx 85% at actual house hold load so 15% more backup e.g. For same backup 135 AH battery will be sufficient.So the total solutions cost decrease about 15% |
| 3 | Bulky and heavy weight around 11-20 Kgs | Compact and light weight just 5-6 Kgs |
| 4 | Rectified unfiltered high rippled DC in Charging as well as in discharging | Filtered pure DC so battery life is more. |
| 5 | LED Display | Attractive LCD display |
| 6 | Robust. | Esthetically sleek design |
| 7 | In Switch OFF condition the Circuit remains ON which consumes battery power | In switch OFF condition battery is totally disconnected |
