  • Page 4: Introduction

    1 Introduction Your new PROwatt 1500 inverter is a member of the most advanced line of 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 PROwatt 1500, it must be installed and used properly. Please read the installation and operating instructions in this manual carefully before installing and using your PROwatt 1500.

  • Page 6: Prowatt 1500 Output Waveform

    2.2 PROwatt 1500 Output Waveform The AC output waveform of the PROwatt 1500 is called a "quasi-sine wave" or a "modified sine wave". It is a stepped waveform that is designed to have characteristics similar to the sine wave shape of utility power. A waveform of this type is suitable for most AC loads, including linear and switching power supplies used in elec- tronic equipment, transformers, and motors.

    3.4 Connections Follow the connection sequence described below. STEP 1 Ensure that the ON/OFF switch on the PROwatt 1500 is in the OFF position. If the power source is a DC power supply, switch it off as well. STEP 2 Connect the cables to the power input terminals on the rear panel of the PROwatt 1500. The red termi- nal is positive (+) and the black terminal is negative (-).

    PROwatt 1500. Leave the test load switched off. STEP 8 Set the PROwatt 1500 ON/OFF switch to the ON position and turn the test load on. The PROwatt 1500 should supply power to the load. If it does not, refer to the troubleshooting section of this manual. If you plan to measure the output voltage of the PROwatt 1500, refer to Section 2.2 of this manual.

    4.2 Battery The battery you use strongly affects the performance you can expect from your PROwatt 1500. It is important to connect the PROwatt 1500 to the correct size and type of battery. The following information will help you select the appropriate batteries for your application.

    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. STEP 2 For each piece of equipment you will be operating from the PROwatt 1500, estimate how many hours it will operate between battery charging cycles.

    Figure 8. Recommended Battery Configuration for Heavy-Duty Applications Note: PW1500/24 model inverter only: 24 Volt systems typically have 2 x 12 Volt batteries connected in series. Battery Tips 1. Lead-acid batteries may emit hydrogen and oxygen gases, and sulfuric acid fumes when recharging. Vent the battery compartment to prevent accumulation of these gases, and do not install electronic or electrical equip- ment in the battery compartment.

  • Page 14: Alternators And Charging Systems

    When possible, recharge your batteries when they are about 50% discharged. This will give you much longer battery cycle life than recharging when the batteries are almost completely discharged. The Statpower TRUEcharge family of battery chargers are designed to maximize your batteries’ performance and useful life (see your Statpower dealer for more details).

    WARNING! 115 Volt AC power is potentially lethal. Do not work on AC wiring while the wiring is connected to the PROwatt 1500 (even if it is switched off) unless the DC power source is physically disconnected from the...
  • Page 16 Connect the ground lead of your AC cable to the internal ground lug on the rear panel of the PROwatt 1500. Strip the hot and neutral leads of your AC cable 1/4 inch (6mm) and connect to the AC output terminal blocks on the PROwatt 1500 circuit board (labeled "...
  • Page 17 2. Do not connect the PROwatt 1500 and another AC source (such as a generator or utility power) to the AC wiring at the same time. The PROwatt 1500 will not operate if its output is connected to AC voltage from another source and potentially hazardous or damaging conditions may occur.

  • Page 18: Ground Wiring

    The PROwatt 1500 has a screw terminal on the rear panel labeled Chassis Ground. This is to connect the chassis of the PROwatt 1500 to ground. The ground terminal in the AC outlet on the front panel of the PROwatt 1500 is connected to the chassis.

    STEP 6 If you are using a battery selector switch, switch it to select one of the batteries. Set the ON/OFF switch on the PROwatt 1500 to the ON position. Check the meters and indicators on the front panel of the PROwatt 1500.

  • Page 21: Operation

    When the switch is in the OFF position, the PROwatt 1500 draws no current from the battery. When the switch is in the ON position but no power is being supplied to the load, the PROwatt 1500 (12 and 24 volt) draws less than 500 milliamperes from the battery.

    Operation of the PROwatt 1500 can interfere with television reception on some channels. If this situation occurs, the following steps may help to alleviate the problem: 1. Make sure that the chassis ground lug on the back of the PROwatt 1500 is solidly connected to the ground system of your vehicle, boat, or home.
