    DC to AC inverters available today. It will give you years of dependable service in your boat, RV, service vehicle or remote home. To get the most out of your Portawattz 3000, it must be installed and used properly. Please read the installation and operating instructions in this manual carefully before installing and using your Portawattz 3000.

  • Page 6: Portawattz Tm 3000 Inverter Output Waveform

    2.2 Portawattz 3000 Inverter Output Waveform The AC output waveform of the Portawattz 3000 is called a “quasi- sine wave” or a “modified sine wave”(see Figure 2). It is a stepped waveform that is designed to have characteristics similar to the sine wave shape of utility power.

  • Page 7: Physical Layout Of The Portawattz 3000 Inverter

    RMS voltage of a modified sine wave correctly. They will read about 2 to 20 volts low when measuring the output of the Portawattz 3000. For accurate measurement of the output voltage, a true RMS reading voltmeter, such as a Fluke 87, Fluke 27, Tektronix DMM 249, or B&K Precision Model 391, must be used.

  • Page 9: Quick Operational Check (Optional)

    You will need the following: a) a 12 volt DC power source b)two cables to connect the DC power source to the Portawattz 3000 c)a test load of 100 - 1000 Watts. d)a line cord to connect the test load to the AC receptacle.
  • Page 10 Attach 5/16” ring terminals to the ends of the wires to be attached to the DC terminals on the Portawattz 3000. The ring terminals should be crimped with a proper crimping tool. Another option is to use Ilsco, or equivalent, box-lug terminals (available at electrical parts suppliers).

    Figure 4. Connections to the Portawattz 3000 STEP 2 - Connect the DC cables to the power input terminals on the rear panel of the Portawattz 3000. The Red terminal is positive (+) and the Black terminal is negative (-).
  • Page 12 WARNING! You may observe a spark when you make the following connection since current may flow to charge capacitors in the Portawattz 3000. Do not make this connection in the presence of flammable fumes. Explosion or fire may result. STEP 5 - Connect the cable from the positive (Red terminal of the Portawattz 3000 to the positive terminal of the power source.

  • Page 13: Permanent Installation

    5 Permanent Installation 5.1 Where to Install The Portawattz 3000 should be installed in a location that meets the following requirements: • Dry - Do not allow water to drip or splash on the Portawattz 3000. •Cool - Ambient air temperature should be between 0ºC and 25ºC (32ºF and 77ºF).

  • Page 14: Battery

    5.2 Battery The battery you use strongly affects the performance you can expect from your Portawattz 3000. It is important to connect the Portawattz 3000 to the correct size and type of battery. The following information will help you select the appropriate batteries for your application.

  • Page 15: Battery Sizing

    The Portawattz 3000 must be connected only to batteries with a nominal output voltage of 12 volts. The Portawattz 3000 will not operate from a 6 volt battery, and will be damaged if it is connected to a 24 volt battery.
  • Page 16 STEP 1 - For each piece of equipment you will be operating from the Portawattz 3000, determine how many watts it consumes. This can normally be found on a label on the product. If only the current draw is given, multiply the current draw by 115 to get the power consumption in watts.

  • Page 17: Using Multiple Batteries

    387 watts. From the chart, the smallest battery size which will give more than 6 hours of operation at a power level between 300 and 400 watts are two 400 amp-hr. batteries in parallel, which offers between 10 and 12 hours of operating time. Average Power Consumption = 2337 watt-hrs ÷...

  • Page 18: Battery Tips

    If you are using different batteries, or need to use more than batteries, recommend that you set up two separate battery banks and use them alternately. Battery selector switches are Figure 7. Parallel Batteries available from marine and RV dealers which allow you to select between two banks of batteries, or use both in parallel, or disconnect both from the load (see Figure 8).

  • Page 19: Alternators And Charging Systems

    TRUECHARGE of battery chargers are designed to maximize your battery’s performance and useful life (see your Statpower dealer for more details). The charging system should be capable of delivering a charging current equal to 25% of the ampere-hour capacity of your battery.

  • Page 20: Battery Cables

    Do not operate the Portawattz 3000 directly from a charging source such as an alternator or solar panel. The Portawattz must be connected to a battery or a well-regulated, high-current DC power supply to work properly.
  • Page 21 Portawattz 3000 is essential to deliver the maximum amount of usable energy to your load. Don’t waste the investment you have made in batteries and a highly efficient inverter by using undersized wires. Use only copper wire. Aluminum wire has about 1/3 more resistance than copper wire of the same size and it is more difficult to make a good, low-resistance connection.

  • Page 22: Connections

    5.4.2 Ground Wiring The Portawattz 3000 has a lug on the rear panel. This is to connect the chassis of the Portawattz 3000, and therefore the inverter’s AC output ground, to your AC distribution system ground.

    DC powered equipment and to properly protect your battery cables. WARNING! You may observe a spark when you make the following connection since current may flow to charge capacitors in the Portawattz 3000. Do not make this connection in the presence of flammable fumes. Explosion or fire may result.

  • Page 24: Operation

    6 Operation To operate the Portawattz 3000, turn it on using the ON/OFF switch on the front panel. The Portawattz 3000 is now ready to deliver AC power to your loads. If you are operating several loads from the Portawattz 3000, turn them on separately after the unit has been turned ON.

    OFF from a conveniently located panel. The remote switch has a push-button and indicator light showing that the inverter is ON or OFF (see your Statpower dealer for more details on the Portawattz Remote ON/OFF switch). 6.1.3. Battery Voltage Indicator The battery voltage indicator displays the voltage at the input terminals of the Portawattz 3000.

  • Page 26: Alarm Indicator

    The Portawattz 3000 will operate most AC loads within these ratings. Some induction motors require very high surge currents to start. The Portawattz 3000 may not be able to start some of these motors even though their rated current draw is within the PROwatt’s limits.

  • Page 27: Accessories

    The remote ON/OFF switch is equipped with a cable which allows the switch to be positioned as far as 20 ft. (6.1 m) away from the Portawattz 3000. The remote switch has a push-button and indicator light showing that the inverter is ON or OFF (see your Statpower dealer for more details on the PROwatt Remote ON/OFF switch).

  • Page 28: Troubleshooting

    Some inexpensive and/or portable stereo systems will emit a buzzing noise from their loudspeakers when operated from the Portawattz 3000. This is because the power supply in the stereo amplifier does not adequately filter the modified sine wave produced by the Portawattz 3000. The solution is to use a sound system that incorporates a higher quality power supply.

    9 Maintenance Very little maintenance is required to keep your Portawattz 3000 operating properly. You should clean the exterior of the unit periodically with a damp cloth to prevent accumulation of dust and dirt. The air intake on the rear panel and air exhaust slots on the front panel are especially prone to dust and dirt accumulation.
