					Whistler inverters convert low voltage, direct current (DC) to 110   
					volt alternating household current (AC). The AC output is called   
					“modified sine wave”. See “Technical Operating Principles”   
					section for more information. Depending on the model and its   
					rated capacity, Whistler inverters draw power either from standard   
					12 volt automobile and marine batteries or from portable high   
					power 12 volt sources.

					IMPORTANT INFORMATION   
					INVERTER INFORMATION   
					Getting Started   
					Power equipment and appliances which operate with motors   
					or tubes require an initial surge of power to get them up   
					and running. This power surge is referred to as the "starting   
					load" or "peak load." (By comparison, electrical devices such   
					as standard light bulbs do not require a large starting load.)   
					Once the equipment or appliance has been powered up, it   
					settles down to a slower pace and requires far less electrical power   
					to operate. This lower power requirement is referred to as   
					the "continuous load."

					About Your New Whistler Inverter.   
					This manual will provide you with directions for the safe   
					and efficient operation of your Whistle Power Inverter.   
					Read the manual carefully before using your new Whistler   
					inverter and keep the manual on file for future reference.   
					mI portantNote:   
					Each of the following operating procedures   
					and safety features must be carefully reviewed and   
					thoroughly understood prior to using the inverter. Failure   
					to do so may result in damage to the inverter, equipment   
					or serious personal injury.   
					In order to ensure that the capacity of your Whistler inverter   
					is sufficient to meet the required start up load, you must first   
					determine the power consumption of the equipment or   
					appliance you plan to operate.   
					Notes:   
					Your Whistler inverter is designed to operate from a 12 volt   
					power source only. Never attempt to connect your   
					Whistler inverter to any other power source, including any   
					AC power source.   
					Power consumption is rated either in wattage or amperes,   
					and information regarding the required "watts" or "amps"   
					generally is stamped or printed on most appliances and   
					equipment. If this information is not indicated on the appliance   
					or equipment, check the owner’s manual. Contact the   
					appliance or equipment manufacturer to determine if   
					the device you are using (TV’s, battery charger, computer,   
					etc.) is compatible with a modified sine wave.   
					• 
					110 volts can be lethal. Improper use of your Whistler   
					inverter may result in property damage, personal   
					injury or loss of life.   
					• 
					• 
					Do not connect the inverter’s output to any other   
					power source.   
					If the power consumption is rated in amps, multiply the number   
					of amps by 110 (AC voltage) to determine the comparable   
					wattage rating. Induction motors may require 2 to 6 times   
					their wattage rating to start up.   
					Not recommended for use with medical equipment.   
					Check with the appliance manufacturer for   
					compatibility with modified sine wave inverters.   
					Some appliances may not work well, not at all or be   
					damaged. This is especially true for medical equipment.   
					For more information on compatibility issues, please visit   
					our inverter FAQ page at: www.whistlergroup.com   
					For further information on the fundamental operating   
					principles of Whistler inverters and related technical   
					data, see "Technical Operating Principles."

					INVERTER INFORMATION   
					Don’t Push It.   
					power overload. Testing appliances and equipment with   
					start up load ratings comparable to your inverter wattage   
					rating will not damage it.   
					Although your Whistler power inverter has the capacity to   
					provide power output (excess current) equal to approximately   
					two times its rated wattage capacity for a very brief period,   
					it is designed to operate equipment and appliances with   
					start up load wattage ratings no higher than its own maximum   
					continuous wattage rating.   
					If a piece of equipment or an appliance will not operate,   
					first confirm that the inverter has been properly connected   
					to the 12 volt power source (See "Making The Connection").   
					If all connections have been properly made, turn the inverter   
					rocker switch ON (l), OFF (O) and ON (l) again in quick   
					succession. If this procedure is unsuccessful, it is likely that   
					the inverter does not have the required start up capacity or   
					your battery supply isn’t large enough to operate the   
					equipment or appliance in question.   
					For example, the Pro-1200W model has a maximum   
					continuous rating of 1200 watts. Although this model has   
					the capacity to briefly provide more than its continuous   
					power (that is, excess current), it is designed to operate   
					equipment and appliances with start up load requirements of   
					1200 watts or less.   
					Selecting the Optimum Power Source.   
					Consequently, if the start up load rating of your equipment   
					or appliance is slightly higher than the maximum continuous   
					rating of the inverter, the inverter will attempt to start loads   
					above the continuous rating.   
					Operating the inverter for extended periods combined with   
					a high continuous load demand may result in excessive   
					power drain from the battery. Therefore, the reserve capacity   
					of the battery you select to power the inverter is an   
					important consideration.   
					Some refrigerators, freezers, pumps and other similar   
					equipment and appliances require very high start up loads   
					to operate. Before attempting to power up this type of   
					equipment or appliance, make certain that all connections   
					have been properly made and that the power source is fully   
					charged.   
					The potential power drain can be estimated by calculating   
					the reserve power ("amp-hour"or Ah) of the battery and   
					the amps required by the inverter to meet the continuous   
					load demand of the equipment or appliance being   
					operated.   
					To determine whether your inverter will operate a particular   
					piece of equipment or appliance, run a test. The inverter is   
					designed to shut down automatically in the event of a

					BATTERY/CABLE INFORMATION   
					BATTERY INFORMATION   
					1. To calculate the Ah of the battery, first determine its   
					"reserve minutes" rating. (Deep cycle marine batteries   
					generally have the highest reserve minute ratings). This   
					rating typically is marked on the battery along with the   
					"Cold Cranking Amps" (CCA) rating. Multiply the reserve   
					minutes rating of the battery by 0.3 to determine the   
					battery approximate Ah rating. A battery with a reserve   
					minutes rating of 166 has an Ah rating of 49.8.   
					• 
					It may be advisable to operate the inverter from a bank   
					of batteries of the same type in a "parallel" configuration.   
					Two such batteries will generate twice the Ah of a   
					single battery; three batteries will generate three   
					times the Ah and so on. See “Making a Connection”   
					on page 13 for more information.   
					This multiple parallel battery option is especially   
					recommended for the Pro-2500W and Pro-3000W   
					inverters due to the high level of amps these models   
					require to produce up to 3000 watts of continuous   
					load. For more information regarding battery power   
					please visit our inverter faq page at:   
					2. To estimate the maximum battery current the inverter   
					will require to run a piece of equipment or appliance,   
					divide its continuous load wattage requirement by 10.   
					The Pro-1200W watt model utilizes 50 amps of battery   
					power to operate an appliance with a 500 watt continuous   
					load requirement. (500W divided by 10V = 50A).   
					www.whistlergroup.com.   
					Wire Cable Gauges   
					3. Conclusion: The reserve power of the battery is sufficient   
					to satisfy the continuous load demand placed on the   
					inverter for a maximum of about one hour. (49.8 Ah   
					divided by 50A = 1 hour).   
					For safe and proper operation of the inverter, connect the   
					inverter to the power source with the proper gauge available   
					and in the shortest length practical.   
					Pro-1200W and Pro-1600W   
					Note:   
					• 
					When the inverter will be operating equipment or   
					appliances with high continuous load ratings for extended   
					periods, it is not advisable to power the inverter with the   
					same battery used to power your vehicle. If the car or truck   
					battery is utilized for an extended period, it is possible that   
					the battery voltage may be drained to the point where   
					the battery has insufficient reserve power to start the vehicle.   
					When the inverter and the battery are set up within three feet   
					of each other, use a minimum of #4 gauge wire to make the   
					connections. Within four to six feet, use a minimum of #2 gauge   
					wire (Pro-1200W), #0 gauge for Pro-1600W. At distances   
					between six feet to ten feet, use #0 gauge wire (Pro-1200W),   
					#00 gauge for Pro-1600W.

					appliance into one of the AC receptacles on the   
					front panel of the the inverter.   
					• 
					Loose connections can result in a severe decrease in   
					voltage which may cause damage to the wires and insulation.   
					• 
					Failure to make proper connection between the inverter   
					and the power source will result in reverse polarity.   
					Reverse polarity will blow the internal fuses in the inverter   
					and may cause permanent damage to the inverter.   
					Damage caused by reverse polarity is not covered   
					under the Whistler warranty.   
					8. Turn the inverter to the ON (I) position. Turn on the   
					equipment or appliance.   
					9. Plug the USB powered device into the inverter’s   
					USB power port.   
					• 
					Making the connection between the Positive (+)   
					terminals may cause a spark as a result of current flowing   
					to the capacitors in the inverter. This is a normal   
					occurrence. Due to the potential for sparking, however,   
					it is extremely important that both the inverter and the   
					12 volt battery be well removed from any possible   
					source of flammable fumes or gases.Failure to heed   
					this warning could result in fire or explosion.   
					Note:   
					• 
					The audible alarm may make a momentary “chirp”   
					when the inverter is turned OFF (O). The same alarm   
					may also sound when the inverter is being connected   
					to or disconnected from the 12 volt power source.   
					• 
					The use of an extension cord from the inverter to   
					the appliance or equipment being operated will   
					decrease the power being delivered to the load.   
					For best operating results, the extension cord   
					should be no more than 50 feet long.   
					6. Run a ground from the Ground Lug Terminal at the   
					rear of the inverter to a proper grounding point using   
					the shortest practical length of 18 AWG wire. Selection   
					of the grounding point will depend on where you are   
					using the inverter. The ground wire may be connected   
					to the chassis of your vehicle or to the grounding   
					system in your boat or to the earth* if you are operating   
					the inverter in a remote location. Before connecting   
					the ground, make certain that the inverter is turned off.   
					Operating the inverter without properly   
					grounding it may result in electrical shock.   
					* This ground can’t be the same ground as the AC ground.

					The Power Source.   
					• 
					Check frequently to ensure that the input and   
					output connections are secure. Loose connections   
					may damage the inverter, the power source, or   
					may generate excessive heat.   
					When the engine is off, most batteries will provide ample power   
					to the inverter for one to two hours. The actual length of time   
					is a function of several variables including the age and   
					condition of the battery, the number of batteries and the power   
					demand being placed on it by the equipment being operated   
					with the inverter. If you are using the inverter while the engine   
					is off, we recommend you start the engine every 30 to 60   
					minutes and let it run for at least 10 minutes to recharge the   
					battery. We also recommend that the device plugged into   
					the inverter be turned off before turning over the engine.   
					To generate the maximum output, the Pro-3000W watt   
					model (for example) should be connected to a power   
					supply which has the capacity to produce up to 300   
					amps. The loads should be distributed between the   
					receptacles to ensure that each outlet is producing no   
					more than its maximum 1500 watt output.   
					Although it is not necessary to turn off the inverter when turning   
					over the engine, the inverter may momentarily cease operation   
					as the battery voltage decreases. When the inverter is not   
					supplying power, and is turned on, it draws low amperage   
					from the battery (see specifications).   
					If more than one piece of equipment or appliance is   
					to be operated at the same time, first turn on the   
					inverter and then turn on each piece of equipment or   
					appliance separately to enable the inverter to produce   
					the required start up loads.   
					For You Television Fans & Audiophiles.   
					Important Information on Battery Chargers   
					Although the inverter is shielded and filtered to minimize signal   
					interference, some interference with your television picture   
					may be unavoidable, especially with weak signals. However,   
					here are some suggestions that may improve the reception.   
					Using your inverter with battery chargers for power tools,   
					flashlights, video cameras and laptop computers may cause   
					damage to the inverter or the charging unit. Check with the   
					appliance manufacturer for compatibility with modified sine   
					wave inverters if you’re unsure.   
					1. First, make certain that the television antenna produces   
					a clear signal under normal operating conditions (i.e.,   
					at home plugged into a standard 110 AC wall outlet).   
					Also, ensure that the antenna cable is properly shielded   
					and of good quality.   
					Although we advise against it, if you attempt to use a   
					charging unit, monitor the temperature of the charging unit   
					for approximately 10 minutes. If the charging unit becomes   
					unusually warm, disconnect it from the inverter immediately.

					Some Powerful Advice.   
					2. Change the relative positions of the inverter, antenna   
					cables and television power cord.   
					When driving with the inverter in operation, make certain that   
					neither the inverter nor the power cords will impede safe   
					operation of your vehicle. Keep the unit and all cords clear   
					of the steering wheel, gas, brake and clutch pedals and gear shift.   
					3. Isolate the television, its power cord and antenna cables   
					from the 12 volt power source by running an extension   
					cord from the inverter to the television set.   
					To maintain your inverter in proper working condition, note   
					the following important safety precautions:   
					4. Coil the television power cord and the input cables running   
					from the 12 volt power source to the inverter.   
					• 
					MOISTURE. Keep the inverter dry. Do not expose it   
					to moisture. Do not operate the inverter if you, the   
					inverter, the device being operated or any other surfaces   
					that may come in contact with any power sources are   
					wet. Water and many other liquids can conduct   
					Note:   
					Inexpensive sound systems may emit a "buzzing" sound   
					when operated with the inverter. This is due to inadequate   
					filters in the sound system. There is no solution to his   
					problem short of purchasing a sound system with a higher   
					quality power supply.   
					electricity which may lead to serious injury or death.   
					• 
					HEAT. For peak efficiency, the ambient air   
					temperature should be between 50° and 80° F. Avoid   
					placing the inverter on or near heating vents,   
					radiators or other sources of heat. Do not place the   
					inverter in direct sunlight.   
					For You Microwave Chefs.   
					The power rating commonly associated with microwave ovens   
					is the "cooking power" which is the power being "delivered"   
					to the item being microwaved. The actual operating power   
					requirement rating is higher than the cooking power rating   
					and typically is referenced on the back of the microwave. If   
					the operating power requirement does not appear on the   
					back of the microwave, check the owner’s manual or contact   
					the manufacturer.   
					• 
					• 
					VENTILATION. In order to disperse the heat generated   
					while the inverter is in operation, keep it well ventilated.   
					While in use, maintain several inches of clearance around   
					the top and sides of the inverter.   
					FUMES & GASES. Avoid using the inverter near   
					flammable materials. Do not place the inverter in   
					areas such as battery compartments, where fumes or   
					gases may accumulate.

					OPERATION   
					OPERATING PRINCIPALS   
					For You Technical Types.   
					The modified sine wave produced by your Whistler inverter   
					has a root mean square (RMS) voltage of 110 volts. The majority   
					of AC voltmeters measure RMS voltage and assume that the   
					measured waveform will be a pure sine wave.   
					1. Basic Operating Principles:   
					Whistler inverters work in two stages. During the first stage,   
					the DC to DC converter increases the DC input voltage from   
					the power source (e.g. a 12 volt battery) to 145 volts DC. In   
					the second stage, the high voltage DC is converted to 110   
					volts (60 Hz AC) using advanced power MOSFET transistors   
					in a full bridge configuration. The result is excellent overload   
					capability and the capacity to operate difficult reactive loads.   
					The output waveform resulting from these conversions is a   
					"quasi-sine wave" or a "modified sine wave" as shown on   
					below.   
					Consequently, these meters will not read the RMS modified   
					sine wave voltage correctly and, when measuring your Whistler   
					inverter output, the meters will read about 20 to 30 volts too   
					low. To accurately measure the output voltage of your inverter,   
					use a true RMS reading voltmeter such as a Fluke 87, Fluke   
					8060A, Beckman 4410, Triplett 4200 or any multimeter identified   
					as "True RMS."   
					For more information on inverters see our Inverter FAQ page   
					at www.whistlergroup.com   
					This stepped waveform is similar to the power generated by   
					utilities and has a broad range of applications.
