Page 26: Designing Your Installation
Designing Your Installation Before doing anything else, you need to determine how you are going to use your PROwatt 1750, 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. -
Page 27: Choosing A Location
Do not install the PROwatt 1750 in a zero-clearance compartment. Overheating may result. The Prowatt 1750 must only be installed in a location that is: Do not allow water or other liquids to drop or splash on it. -
Page 28: Connecting To An Existing Ac Circuit
Connecting to an Existing AC Circuit You can plug loads directly into the AC receptacle on the front panel of the PROwatt 1750. You can also connect the inverter to an existing AC circuit and then plug loads into the receptacles connected to that circuit. -
Page 29: Ac Wiring Procedure
7. Strip 1/4 inch (6 mm) of insulation from the line (black) and neutral (white) leads, and connect them to the AC output terminal blocks on the PROwatt 1750 circuit board. These terminal blocks are labeled respectively as shown in Figure 3-1. -
Page 30: 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 1750, 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 31 Connecting to an Existing AC Circuit 1750 Figure 3-2 Simple Transfer Switching Green/GND White/N Black/L 1750 PROwatt Shorepow er or Generator W hite/N Black/L Auto Transfer Switch White/N Black/L Green/GND Green/GND Figure 3-3 Automatic Transfer Switch Manual and automatic transfer switches are available from marine and RV dealers.

Page 34: Connecting Dc Cables
PV array. Connecting DC Cables To operate safely and effectively, the PROwatt 1750 needs proper cables, wiring, and fuses. Because the PROwatt 1750 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 your load. -
Page 35: Fuse/Circuit Breaker Sizing Guidelines
Connecting DC Cables Fuse/Circuit Breaker Sizing Guidelines Because your batteries can produce thousands of amps, you need fuses or circuit breakers that can safely withstand the short-circuit current they can produce. To select the correct fuse type and size: 1. Determine the total cold cranking amp rating for your battery(s). (The cold cranking amp rating of each battery is displayed on the battery case. -

Page 57: Battery Size
Battery Size CAUTION The PROwatt 1750 must only be connected to batteries with a nominal output voltage of 12 volts. The PROwatt 1750 will not operate from a 6 volt battery and will be damaged if connected to a 24 volt battery. -
Page 58: 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 1750. 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 59: 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). -
Page 60: Using Multiple Batteries
Battery Types and Sizes Using Multiple Batteries As your power requirements increase, you may need to use more than one battery to obtain sufficient capacity. Read “Two Batteries Connected In Parallel” “Two Separate Battery Banks” to determine whether two batteries or two battery banks are more appropriate for your applications. Two Batteries Connected In Parallel Two identical batteries can be connected positive (+) to positive (+) and negative (–) to negative (–) in a parallel system. -
Page 61: Two Separate Battery Banks
Using Multiple Batteries Two Separate Battery Banks If you need more than two batteries (or are using different makes or models of batteries), Xantrex recommends that you install two separate battery banks and a battery selector switch. Figure B-2 shows two separate battery banks and a battery selector switch. -
