2.1.2 Control Panel The Control Panel provides ‘0/|’(Off/On) 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. -
Page 7: Mounting The Quietpower Inverter
Mounting the QuietPower Inverter Before mounting the QuietPower Inverter, test the chosen location for adequate space around the unit to allow for connections and ventilation. Mounting hardware should be corrosion resistant and ¼” or 6 mm diameter screws. Your mounting system should be able to support three times the weight of the QuietPower Inverter, which weighs approximately 16 pounds (7.3Kg). -

Continuous AC Output Current Rating QP-1800 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. -

Page 14: Battery Information
This type of battery is often labeled as a marine, recreational vehicle, or golf cart battery. Iris Technology recommends you use one or more of these batteries separated from the starting battery of your vehicle or boat with a battery isolator. -
Page 15: Battery Size
(e.g. 5O Ah). Even if your battery is in excellent shape and fully charged you will likely experience poor surge power performance and unsatisfactory operating time with anything but a small AC load. Iris Technology recommends a minimum battery size of 200 Ah for moderate loads (< 1000 W) and greater than 400 Ah for heavy loads. -
Page 16: Performance Graphs And Specifications
Temperature” illustrates the relationship between power output and ambient temperature. The rated power output of the QP-1800 inverter is 1800W up to 25°C ( 77°F). Operating the unit above this temperature will result in thermal shutdown or decreased performance. At input voltages less than 24V, the unit runs warmer which will cause thermal shutdowns at temperatures below these ambient temperature guidelines. -

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. -

Page 20: Appendix A. Technical Addendum
We have heard questions about a “short” operating runtime with this equipment. In field tests at Camp Pendleton, we measured and verified conversion efficiency of the QP-1800 to be approximately 90%, well within specifications. The QuietPower 1800 equipment, by its very design, can demand a large current drain from the vehicle electrical system (75 to 90 Amperes depending upon battery voltage and load). - Page 21 Operation with Power Strips We see an occasional compatibility issue with power strips having integral surge suppressor components (MOVs). The QuietPower 1800 provides surge suppression at the output and no additional suppressors are typically needed. In fact, the use of additional surge suppressors is not recommended. We have evaluated alternate power strips with this equipment and have not seen this issue recur.

Questions and answers
My QP turns on but the screen only says 24V 120V 60Hz, is not able to charge anything.
The QP-1800 may only display 24V 120V 60Hz and not charge anything due to one or more of the following reasons:
1. Weak or Dead Batteries: The inverter needs strong, fully charged batteries to operate. Weak or damaged batteries may not supply enough power.
2. Loose or Corroded Battery Connections: Poor connections can prevent the system from delivering adequate current.
3. Inadequate Battery Capacity: The battery must have sufficient Ampere-Hours (AH) to support the inverter load.
4. DC Input Voltage Out of Range: The inverter operates between 20 to 32 VDC, with peak performance between 24 to 30 VDC. If voltage is outside this range, the inverter may not function properly.
5. High Surge Loads: Some equipment with high startup currents may not start if the inverter-battery system cannot provide the required surge.
6. Improper DC Cable Sizing: Undersized cables can limit current flow, affecting performance.
Check battery condition, cable connections, voltage levels, and load compatibility to resolve the issue.
