There are many advantages of true sine wave over other waveforms delivered by other
inverters:
AC powered equipment is designed to operate with true sine wave. Many loads will
perform better when connected to the QuietPower Inverter.
Motor loads start easier.
Reduced stress on surge protection circuitry within the equipment means potentially
longer equipment life.
Many advantages of true sine wave are also due to the absence of the sharp-rising edges of
waveforms prevalent in either modified sine wave or square wave inverters. Some of these
advantages are:
Reduced interference in audio and electronic equipment, especially those that use less
complex internal power supplies.
Significantly reduced in-rush current into capacitive loads and reduced stress on the
output devices of the inverter, potentially lengthening equipment life.
Motor loads generally operate cooler and quieter without the extra harmonic distortion
generated by a modified sine wave.

Control Panel
Once the QuietPower Inverter is properly installed and connected
to the batteries, it is ready to begin delivering AC power to your
loads. The control panel is the interface between you and the
inverter. The information below describes the features of this
panel, and is followed by other sections that contain inverter
operating information.
1. INVERTER OFF/ON (O
/
I)
SWITCH. Turns the
Inverter On when set to the „
I
‟ position, and Off when
set to the 'O' position. It is also used to enable or
disable POWERSAVE mode during the power-up
sequence.
Figure 8: QP-1800 Control Panel
2. LIQUID CRYSTAL DISPLAY (LCD) DISPLAY. Displays input current from the
battery and battery voltage numerically. A multi-segment bar graph displays actual
output power in watts from the inverter when a load is being operated.
3. CONTROL PANEL. The control panel is designed so it can be removed and re-
attached to the chassis in 90-degree increments depending on the mounting
orientation of the inverter itself. The panel can also be removed entirely from the
unit and mounted remotely, with the purchase of the optional QuietPower Interface
Panel.
4. FAULT CONDITION DISPLAY. Should a fault occur, the error will immediately be
displayed on the LCD Display. An audible alarm sounds and the back-lighting of the
display will flash to draw attention to the fault condition (refer to paragraph 4.3.1).
