· QuietPower model number (1800 watt)
· Input Voltage, Output Voltage and Frequency configuration
· POWERSAVE mode OFF (factory set default)
Following the display of this information, the control panel then defaults to the standard display
information of input voltage, input current and output power. When a load is connected, the output power
(watts) is displayed in bar-graph form.
Once the standard display screen is shown, the QuietPower Inverter is ready to deliver AC power to your
loads. You can now plug in a load to the front outlet of the unit. The loads should operate from the
inverter as they would from utility power. Section 4.5 explains the operating limits for the QuietPower
Inverter.
4.4 QuietPower POWERSAVE Mode
Your QuietPower Inverter has a function mode called POWERSAVE. This “sleep” mode shuts off much
of the power control circuitry of the QuietPower Inverter as well as the display back-lighting, reducing the
standby current draw considerably. With this mode enabled, the unit draws approximately 1.5 watts while
powered up but with no load on the inverter. The QuietPower Inverter detects the presence of a load by
sending out pulses approximately once every 2.5 seconds. Full output power is available with the
detection of a load. The unit will remain in POWERSAVE mode if the load it detects is less than 10W for
the QuietPower 1000 and less than 20W for the QuietPower 1800. This is a factory set search mode
setting and cannot be changed.
You would want to enable POWERSAVE mode if the inverter is only being used periodically to power
loads. This allows the inverter to draw less power from the batteries during non-use periods. If the
inverter is being used frequently and your batteries are being recharged during inverter use (e.g. vehicle
alternator), or soon after inverter use, you can leave POWERSAVE disabled.
Your QuietPower is factory default set to POWERSAVE OFF. To enable the POWERSAVE mode, follow
these steps:
I) Turn the Control Panel switch to ‘0’ position
2) Switch the unit back to ‘|’ position. You will see the power-up information being displayed as
described previously (model number and voltage/frequency configuration)
3)
When the Control Panel displays “POWERSAVE OFF” turn the switch to ‘0’ position, wait for
approximately 3 seconds, and then turn the switch back to ‘|’ position again. “POWERSAVE ON” will
now be displayed during the start-up sequence and when the normal state display appears, a small
pointer will be visible, indicating POWERSAVE mode is enabled. Follow the same procedure for
disabling POWERSAVE mode.
4.5 Inverter Operating Limits and Protection Features
Power Output: The QuietPower 1800 delivers 1800 watts continuously. The following table displays the
continuous and peak current ratings as well as surge rating:

The unit above will be able to operate all AC loads rated at or below these power ratings. Some high
horsepower induction motors used in pumps and other motor-operated equipment require very high surge
currents to start and the QuietPower Inverter battery combination may have difficulty starting these loads.
