1.3 Inverter Key Features
The QuietPower Inverter utilizes advanced high frequency switching technology in the power
conversion process. The circuits are similar to those used in power supplies for computers and
other electronic equipment. This technology offers several benefits:
Light weight: for easy installation
Pure sine wave output: for reduced interference
High surge capability: for „hard-to-start” AC loads
High frequency switching: for nearly silent operation
Refer to paragraph 3.7, Performance Graphs and Specifications, for complete specifications.
1.3.1 Inverter Function
When connected properly and the power switch is turned to the „I‟ (On) position, the QuietPower
Inverter draws power from the 24 VDC (nominal) battery and/or vehicle electrical bus and
delivers a true sine wave 115 VAC (nominal @ 15 A) output. As long as the input voltage is
maintained within the operating range of the unit, the QuietPower will continue to deliver AC
power to the loads connected. High and low battery shutdowns will engage if the battery
voltage falls out of the specified range of operation (20-32 VDC).
1.3.2 Control Panel
The Control Panel provides Off/On („O/I‟) control and displays operating information so you can
monitor the status of the Inverter and your batteries.
This panel can be removed and re-attached in different orientations so the display information is
directed at you in the most convenient fashion for all recommended mounting configurations.
The procedure to rotate the panel is found in section 2.5.
