Its more efficient than that. I think somewhere around 85%. It could be that your using a modified sine wave inverter. Contact the manufacturer of the UPS and see if it requires a pure sine wave. You could buy a capacitor and place it before the inverter. 1/2 farad should work for that. And just forget about the UPS.
