3.7.2 Efficiency Curve
The efficiency rating of the QuietPower Inverter indicates what percentage of DC power is
converted to usable AC power at given power output levels. The higher the rating, the less
power is lost in the way of heat from the inverting process. QuietPower Inverters have an
extremely flat efficiency curve over much of their operating range so less battery power is
wasted, whether operating at low power levels or higher power levels (refer to Figure 10).
