Iris Technology Operator's Manual QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

Explosive Gas Precautions

 This equipment contains components which can produce arcs or sparks. To

prevent fire or explosion do not install in compartments containing batteries or flammable materials or in locations which require ignition protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connection between components of the fuel system.

 Working in the vicinity of a lead-acid battery is dangerous. Batteries generate

explosive gasses during normal battery operation.

 To reduce the risk of battery explosion, follow these instructions and those

published by the battery manufacturer and the manufacturer of the equipment in

which the battery is installed.

Precautions When Working With Batteries

 Do not work alone. Someone should be within range of your voice or close enough to

come to your aid when you work near a lead-acid battery.

 Have plenty of fresh water and soap nearby in case battery acid contacts skin,

clothing, or eyes.

 Wear complete eye protection and clothing protection. Avoid touching eyes while

working near batteries.

 Wear eye protection to keep corrosion from coming in contact with eyes, when

cleaning battery terminals and before making connections.

 If battery acid contacts skin or clothing, wash immediately with soap and water. If

acid enters eye, immediately flood eye with running cold water for at least 20 minutes and get medical attention immediately.

 NEVER smoke or allow a spark or flame in vicinity of battery or engine.  Do not drop a metal tool on the battery, nor allow metal to contact the battery

terminals or vehicle chassis. The resulting spark or short-circuit on the battery or other electrical part may cause an explosion.

 Remove personal metal items such as rings, bracelets, necklaces, and watches

when working with a lead-acid battery. A lead-acid battery produces a short-circuit

current high enough to weld a ring or the like to metal, causing a severe burn.

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.

2.5 Mounting the 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 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). The more clearance for ventilation around the unit, the better the performance. At a minimum,

have 5” of free space on all sides of the inverter. For your convenience, four (4) Neoprene

Cylindrical Sandwich Mount Vibration Isolators and attachment hardware are provided for shock mounting.

Mount the QuietPower Inverter on either a horizontal or vertical surface (such as a bulkhead) using the mounting holes provided. For secure, permanent mounting, use at least four (4) mounting holes. Optionally, use four shock mounts provided. For safety requirements, the QuietPower Inverter must be mounted in one of the three orientations shown in Figure 3 below. Mounting it in one of the two (2) prohibited configurations could allow foreign objects to drop into the AC receptacle, controls, or cooling fan.

2.5.1 Control Panel Orientation

The QuietPower QP-1800 control panel can be detached and reoriented to facilitate accessing the panel in various mounting positions. Remove and re-attach the control panel depending on the orientation of the base unit itself. For example, if the unit is mounted on a vertical surface, you may want to remove the panel and attach it so it is again readable horizontally.

Figure 4: Control Panel Rotation and Attachment

This can be done as follows: (Refer to Figure 4 right);

1. Using the Philips screwdriver, remove the 4 screws on the outer edges of the control panel.

2. Lift the panel straight-up, out of the housing

3. Rotate the panel to the desired orientation.

4. Reattaching the panel to the base unit.

5. Re-install and secure all four screws.

2.6 Wiring the Inverter

The DC connections must be complete as the first step in wiring the inverter, then the grounding connections before the unit is ready to deliver AC power via the duplex outlet.

2.6.1 Making DC Wiring Connections

The cable for the QuietPower Inverter System is approximately 12 feet long and is fabricated from 2/0 AWG multi-strand flexible wires. It is terminated with a NATO Plug at one end and with two (2) lug terminals connecting to the Inverter at the other end. This cable is supplied as a part of the Inverter System (PN 287A107) or Inverter Complete (PN 287A120). It is also available separately as PN 287A106 to be used with the Inverter (PN 287A101)

2.6.2 DC Grounding (On-Vehicle)

The QuietPower Inverter has a lug on the rear panel labeled Chassis Ground. This lug is used to connect the chassis of the QuietPower Inverter to your DC ground as required for safety. Use #6 AWG or larger copper wire (green if insulated) and secure it to the chassis lug as well as the grounding point in your vehicle (usually the chassis).

2.6.3 DC Grounding (Off-Vehicle)

When the vehicle comes to a stop, the inverter may be used to power off-vehicle accessories. It is necessary to make an additional grounding connection between the grounding point on the vehicle and the ground rod to make connection with earth. The chassis connections of the offvehicle accessories must also be connected to this same ground rod.

Section 3 Operation

3.1 General

This section details how the unit functions as an inverter, provides information on the control panel, describes operating limits, and provides performance data and system specifications.

3.2 Principles of Operation

The QuietPower Inverter converts DC power (24V) into 60 cycle 115VAC (utility power) power from batteries and the vehicle electrical bus. This is done by the Inverter internally in two stages. The first stage is a DC-to-DC converter, used to raise the low voltage DC input to high voltage DC. The second stage is the actual inverter stage, taking the high voltage DC and converting it to a precise, true sine wave AC output.

The DC-to-DC converter stage uses modern high frequency power conversion technology that eliminates the bulky, low frequency (50/60 Hz) based transformers found in inverters using older technology. The inverter stage uses advanced power semiconductors that provide excellent overload capabilities.

3.3 Output Waveform

The AC output waveform of the QuietPower Inverter is a “true sine wave” with typically 1% Total

Harmonic Distortion (THD). Figure 7 illustrates the output waveform from the QuietPower Inverter. This waveform is nearly identical to your utility-supplied power and in some cases where utility power is poor, the QuietPower Inverter delivers cleaner, more precise AC power.

Figure 7: QuietPower Inverter True Sine Wave Output

Page 25 of 56 Rev 12 APR 2010

Iris Technology Operator's Manual QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

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.

3.4 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.

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.

Figure 8: QP-1800 Control 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).

Page 26 of 56 Rev 12 APR 2010

Iris Technology Operator's Manual QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

3.4.1 To operate the QuietPower Inverter:

Turn the unit ON by moving the rocker switch on the control panel to „I‟ position. The following

information will be displayed (upon each power-up), identifying the type and configuration of your QuietPower:

 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 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 duplex outlet of the unit. The loads should operate from the inverter as they would from utility power. Paragraph 3.6 explains the operating limits for the QuietPower Inverter.

3.5 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 backlighting, 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 should 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, do the following:

1. Turn the Control Panel switch to „O‟ position

2. Switch the unit back to „I‟ 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 „O‟

position, wait for approximately 3 seconds, and then turn the switch back to „I‟ 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.

3.6 Inverter Operating Limits and Protection Features

Power Output: The QuietPower 1800 delivers 1800 watts continuously. Table 2 displays the continuous and peak current ratings as well as surge rating.

Table 2: Operating Limitations

The QuietPower Inverter 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. If you have problems with certain loads, ensure that battery connections are solid, your DC wires are appropriately sized, and that the battery is of sufficient capacity and fully charged. It may be necessary to operate the vehicle (possibly continuously) and to power the inverter from the alternator.

Input Voltage: The QuietPower Inverter operates from an input voltage ranging from 20 to 32 VDC.

Peak performance for these inverters occurs when DC input voltage is in the range of 24 volts to 30 volts for 24V models. The QuietPower Inverter will indicate high and low DC voltage conditions as shown in Table 3.

Table 3: System Trip Voltages

The over-voltage protection and shutdown protects the inverter against excessive input voltage, should the unit be connected to a higher voltage than it is designed for (up to 35 VDC - higher voltages may cause damage). Low input voltage shutdown protects your battery from being over-discharged. The QuietPower Inverter requires a manual reset to re-start after shutdown from either high or low input voltage. Turn the power switch to „O‟ and then back to „I‟ to re-start the unit.

Output Overload Protection: A short circuit may be applied to the output continuously without damage to any internal components. The QuietPower Inverter will shutdown in less than five seconds when the output falls 10% below the nominal voltage as a result of current limiting.

WARNING

DO NOT DISASSEMBLE THE QUIETPOWER INVERTER. ONLY QUALIFIED ELECTRONICS MAINTENANCE TECHNICIANS ARE PERMITTED TO REPLACE THE FUSE. ATTEMPTS TO SERVICE THE INVERTER BY UNQUALIFIED PERSONNEL MAY RESULT IN A RISK OF ELECTRIC SHOCK OR FIRE. REFER TO SECTION 6, WARRANTY AND SERVICE, FOR INSTRUCTIONS ON SERVICING THE INVERTER.

WARNING

MAKE SURE INVERTER IS ELECTRICALLY DISCONNECTED FROM 24 VDC POWER SOURCE (NATO PLUG) PRIOR TO SERVICING. FAILURE TO DISCONNECT CABLE FROM 24 VDC POWER SOURCE (NATO PLUG) FIRST MAY RESULT IN FIRE, SEVERE ELECTRIC SHOCK, OR DEATH.

QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

Input Reverse Polarity Protection: the internal circuitry of the QuietPower Inverter is protected by an internal, 32V, fast-blow fuse. This fuse is only replaceable by qualified service personnel. In many reverse polarity conditions, this fuse will protect internal circuits, however, certain high voltage/current situations may cause internal damage. Refer to Section 6.3, Fuse Replacement.

3.7 Performance Graphs and Specifications

3.7.1. Power Derating Curve

As with all inverters, the amount of continuous power that the QuietPower Inverters can deliver without overheating is limited by ambient (surrounding air) temperature. The nominal temperature for the power ratings specified for the QuietPower Inverters is 25° C (77° F). They will operate and deliver their continuous power ratings at higher temperatures, but the extent to which they can do this is limited by the ambient temperature as well as the input voltage from battery. Figure 9 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.

Operating the unit in conditions outside the power and temperature limits (“above” and “to-the-

right” of the derating curves) will result in thermal shutdown and/or significantly decreased

performance. In addition, operation in this range is outside of the ratings covered by the product‟s regulatory approvals.

These curves are published for information purposes only to let you know what may happen while operating in high ambient temperature conditions. Under normal battery voltage conditions and non-extreme temperatures, inverter operation will be within the derating curve.

Under conditions of extreme low temperature -20° C (-4° F), the inverter may not start under full load. Once started, however, the inverter will support a full load of 1800 W with no derating at 20°C.

Figure 9: Output Power (W) Derating Curve

Iris Technology Operator's Manual QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

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).



Under even ideal conditions the typical capacity of a vehicle battery is about 60 minutes (engine off condition). Cold Temperatures reduce battery output severely and can shorten battery life considerably.

CAUTION

The vehicle battery can be discharged by inverter usage to the point of insufficient power to start the vehicle rendering it inoperative. The inverter should not be used for extended periods ( + 45 minutes) with the vehicle engine off.

Since the condition of the vehicle battery is unknown it is recommended that drawing from the vehicle battery alone be used for short periods of time even with light loads.

QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

3.8 Usage Guidelines for the QP-1800

When using the QP-1800 in vehicle installations, it is important to understand that the vehicle battery holds a limited amount of power from which the QP-1800 inverter draws to supply voltage.

When the vehicle engine is running, the battery is recharged and in most conditions the QP-1800 will supply power as long as there is fuel to run the vehicle engine.

In vehicle engine-off situations, the QP-1800 draws power from the battery which is limited.

VEHICLE CONSIDERATIONS

A.1 Vehicle Alternator

This appendix explains important vehicle and battery systems information necessary to optimize the performance of the QP-1800 inverter system.

The QuietPower 1800 is a 24 VDC (nominal) device. It will not operate from personal vehicles which have a 12 VDC (nominal) electrical system.

A 200 Amp alternator system is recommended to deliver full power output (100 Amp minimum). Under conditions of high power draw, an undersized alternator will be damaged.

A.2 Military Batteries

An automotive starting battery is designed to deliver a large amount of current for a short period

of time (so it can start your engine). Only a small portion of the battery‟s capacity is used when

starting the engine and it is quickly recharged by the running engine. It is not designed for repeated charge-discharge cycles where the battery is almost completely discharged and then recharged. Starting batteries used in this kind of deep discharge service will wear out rapidly.

Just as important as the type of battery selected for use with your QuietPower Inverter is the subject of battery size or capacity. Unfortunately, there are a number of different standards for rating battery energy storage capacity. Automotive starting batteries are normally rated by cranking amps. This is not a relevant rating for continuous use. Deep cycle batteries are rated either by reserve capacity in minutes or by amp-hours. Battery reserve capacity is a measure of how long a battery can deliver a certain amount of current - usually 25 amps. For example, a battery with a reserve capacity of 180 minutes can deliver 25 amps for 180 minutes before it is completely discharged. Amp-hour capacity is a measure of how many amps a battery can deliver for a specified length of time - usually 20 hours. For example, a typical marine or RV battery rated for 100 amp-hours can deliver 5 amps for 20 hours. (5 amps * 20 hours = 100 amp-hours).

The batteries are a very important part of your system, so we recommend you have as much battery capacity as possible. A large battery will extend running time and ensure your QuietPower Inverter delivers full rated surge.

You can expect performance from the inverter to suffer with the use of a small, low amp-hour rated battery (e.g. 50 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 100 Ah for moderate loads (< 1000 W) and 200 Ah or greater for heavy loads.

A.3 Load and Runtime

The user must understand two key concepts relating to equipment load and runtime. First, the total load must never exceed the temperature derated capacity of the QP-1800 (see Figure 9). As temperatures increase, the capacity of the inverter decreases. Secondly, if the equipment is to be operated without the engine (and alternator) running, the capacity of the batteries will establish a maximum runtime before they are depleted and not able to restart the vehicle. The ideal limit for these military batteries is about 2400 W-hr. This assumes a new, freshly charged batteries with ideal connections and at standard temperatures. A safety factor of 2 to 4 should be allowed. Interestingly, the nature of these batteries is that their capacity increases with temperature (see Figure 13). This planning is very mission specific and should be revisited regularly. To understand power required for typical loads, Table 12 is provided as reference. This table is a representation of approximate load values for various commercial appliances and military radio power adapters. These are meant for a general comparison. Wattages may vary according to manufacturer. For exact ratings refer to the appliance tag or Technical Manual.

Appendix B

TECHNICAL ADDENDUM

This technical addendum has been prepared to address concerns raised in regards to degraded inverter performance specifically: shortened runtime - in the field. Root cause investigation has revealed that in cases where the inverter malfunction is not the cause, vehicle condition and environmental factors can severely affect the function and performance of the inverter.

B.1 QP-1800 Performance with Vehicle and Environmental Factors

The performance of the QP-1800 inverter can be affect by external factors:

 Temperature (battery)  Age and condition of the vehicle battery & charging system  Condition and integrity of the vehicle cabling

B.1.1 Temperature Effects on Battery Performance

Cold temperatures decrease the output and efficiency of the vehicle battery, and thus the ability of the inverter to draw power from the battery will be limited. Figure 13 shows typical runtime in hours over various temperature ranges. Users should be aware that the output of the vehicle battery and inverter will be shorted in cold weather conditions.

QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

B.1.2 Age and Condition of the Vehicle Battery

Older batteries; nearing end of operational life and lead acid batteries with insufficient water will provide less output. A simple voltage measurement at the batteries terminal is not a reliable indicator of a batteries capacity to provide power for prolong periods. Lead acid batteries recover to relatively high voltages even if they are weak or damaged. It is important to measure the holding voltage across these batteries while loaded employing a battery tester that provides voltage measurements under load. Inverter performance will be optimal with new or a well maintained vehicle battery.

B.1.3 Condition and Integrity of the Vehicle Cabling

To operate effectively, all connections within the vehicle electrical system must be clean and very secure. Chemical corrosion is a common factor with battery cabling, over time corrosion will severely degrade the electrical current the cabling can carry and limit the power the inverter can receive. Even a new battery with degraded cabling will not provide sufficient output to the inverter. Periodic checking of the cable and battery terminal connections can improve and maintain the inverter performance.

B.1.4 Loose Connections

Loose connections of the cabling will degrade the electrical contact between the battery and the inverter and severely limit the power the inverter can receive. Periodic checking of the cable and battery terminal connections can improve and maintain inverter performance.

B.2 Operation with Surge Suppression Power Strips

Occasional incompatibility can occur with the QuietPower 1800 and power strips having integral surge suppressor components (MOVs). The QP 1800 provides surge suppression at the output and no additional suppressors are typically needed. 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. A similar but related issue, with the Ground Fault Circuit Interrupter (GFCI) discussed next.

B.3 Operation with Downstream EMC Components

The QuietPower 1800 is delivered with a Ground Fault Circuit Interrupter (GFCI) type duplex outlet. Occasionally, when operated with certain types of electronics, the GFCI would trip for no apparent reason. The following discussion provided a basic understanding of the operational issues.

Ground Fault Circuit Interrupters (GFCIs) are important for minimizing shock hazards in outdoor and potentially wet areas. They are now generally required by the National Electronic Code (NEC) in these locations. However, what the GFCI detects to protect people - an imbalance in the currents between the Hot and Neutral wires caused, possibly, by someone touching a live conductor – may exist safely by design in three (3) wire grounded electronic equipment and consequently result in the false tripping of the GFCI. The reason is that there are usually small

Iris Technology Operator's Manual

Appendix A

Rev 12 APR 2010

QuietPower 1800 (QP-1800) Doc 287.F701 / 100412

filter capacitors between all three wires (Hot, Neutral, and Ground) in the EMC line filters of many computer and military electronic systems. At power-on and often while operating there may be enough leakage current through the capacitors, between Hot and Ground especially, to falsely trip the GFCI. Even for ungrounded two (2) wire devices, the power-on surge into inductive or capacitive loads as presented by switching power supplies may falsely trip the GFCI. This is more likely to happen with multiple devices plugged into the same GFCI protected outlet especially if they are controlled by a common power switch.

Ground fault currents can properly result from deteriorating wiring; contact contamination due to moisture, oil or dust; insulation breakdown; or other conditions which are indicators that repairs need to be made.

We have verified the operation of the QuietPower 1800 for compatibility with the PAC-216/U and VB-90 adapters for SINCGARS, the PAC-24V adapter for the Falcon series, the StarPower solar power system, laptop and desktop computer systems (including monitors and laser printers), cellular telephone rechargers, fluorescent lamps, and Uninterruptable Power Supplies manufactured by APS. This system is also compatible with personal electronics (radios) and, importantly, most coffee makers.
