    Designing Your Installation Before doing anything else, determine how you are going to use your PROwatt 3000, and on the basis of that, design a power system that will give you maximum performance. The more thorough your planning, the better your power needs will be met. In particular, you need to: •...

  • Page 29: Choosing A Location

    Do not install the PROwatt 3000 in a zero-clearance compartment. Overheating may result. The PROwatt 3000 must only be installed in a location that is: Do not allow water or other liquids to drop or splash on it.

  • Page 30: Connecting To An Existing Ac Circuit

    • green = ground Do not connect the PROwatt 3000 and another AC source (such as a generator or utility power) to the AC wiring at the same time. The PROwatt 3000 will not operate if its output is connected to AC voltage from another source, and potentially hazardous or damaging conditions may occur.

  • Page 31: Ac Wiring Procedure

    Connecting to an Existing AC Circuit If you install the PROwatt 3000 into an electrical system that also uses power from a generator or a utility line, you must include a switch that prevents the inverter and the other power source from being connected to the AC distribution system at the same time.
  • Page 32 CAUTION: Reverse Polarity Improper connections (connecting a line conductor to a neutral conductor, for example) will cause the PROwatt 3000 to malfunction and may permanently damage the inverter. Damage caused by a reverse polarity connection is not covered by your warranty.

  • Page 33: Installing Transfer Switches In Ac Circuits

    Installing Transfer Switches in AC Circuits If you are using another AC source on the same circuit as the PROwatt 3000, install a transfer switch to ensure that the sources never power the circuit at the same time. The switching mechanism can be as simple as a plug that you insert in the desired AC power source.

  • Page 34: Installing The Remote On/Off Switch

    Installing the Remote On/Off Switch The remote switch lets you turn the PROwatt 3000 on and off from a convenient location—up to 20 feet (6 m) away from the inverter—while the inverter is mounted out of sight and close to the batteries.

  • Page 35: Mounting The Inverter

    WARNING: Electrical Shock Hazard Never operate the PROwatt 3000 without connecting it to the ground. Electrical shock could result. The PROwatt 3000 has a ground lug on the outside of the rear panel as shown in Figure 3-4. Follow the guidelines in “Grounding Locations”...

  • Page 36: Grounding Locations

    Installation Chassis Ground Figure 3-4 Rear Panel Connections The neutral (common) conductor of the inverter AC output circuit is connected to the chassis ground. Therefore, when the chassis is connected to ground, the neutral conductor is also grounded. This conforms to National Electrical Code requirements stating that separately derived AC sources (such as inverters and generators) must have their neutral conductors tied to the ground in the same way that the neutral conductor...

  • Page 37: Connecting Dc Cables

    PV array. Connecting DC Cables To operate safely and effectively, the PROwatt 3000 needs proper cables, wiring, and fuses. Because the PROwatt 3000 has low-voltage, high- current input, low-resistance wiring between the battery and the inverter is essential to deliver the maximum amount of usable energy to the loads.

  • Page 38: Dc Fuses

    Installation DC Fuses Xantrex recommends a 400 amp Class T or Class RK5 fuse such as a Bussman JJN or FRN. Cabling Procedure Follow the installation procedure given below and consult Figure 3-5 Figure 3-6 for additional details that are specific to your installation.
  • Page 39 Figure 3-6 Configuration for Heavy Loads To connect the DC cables: 1. Ensure that the On/Off switch on the PROwatt 3000 is off. If you are using a battery selector switch, switch it off as well. 2. Cut the cables to the correct length.

  • Page 63: Battery Size

    Battery Size CAUTION The PROwatt 3000 must only be connected to batteries with a nominal output voltage of 12 volts. The PROwatt 3000 will not operate from a 6 volt battery and will be damaged if connected to a 24 volt battery.

  • Page 64: Estimating Battery Requirements

    To determine how much battery capacity you need: 1. Determine how many watts are consumed by each appliance that you will operate from the PROwatt 3000. You can normally find this on a label on the product. If only the current draw is given, multiply it by 115 to get the power consumption in watts.

  • Page 65: Battery Sizing Worksheet

    Estimating Battery Requirements This example illustrates how quickly your battery needs can escalate. To reduce the required battery size, you can conserve energy by eliminating or reducing the use of some loads or by re-charging more frequently. When sizing your battery, resist the temptation to skip the last step of this calculation (multiplying by 2).
