1. Introduction
The Xantrex PROsine Inverter is designed to convert DC (Direct Current) power from batteries into clean, reliable AC (Alternating Current) power. This true sine wave output is identical to the AC power supplied by utility companies, making it suitable for sensitive electronic loads. It is engineered for both recreational and industrial applications, ensuring optimal performance for a wide range of AC equipment, including televisions, audio systems, and power tools.
2. Safety Information
Read all instructions and cautionary markings on the inverter, the batteries, and all appropriate sections of this manual before installation and operation. Failure to follow these instructions may result in electrical shock, fire, and/or severe injury.
- Electrical Shock Hazard: Do not open the inverter. There are no user-serviceable parts inside. Refer servicing to qualified service personnel.
- Fire Hazard: Do not install the inverter in compartments containing flammable materials or in locations that require ignition-protected equipment.
- Battery Safety: Work in a well-ventilated area. Batteries can produce explosive gases. Do not smoke or allow sparks or flames in the vicinity of the battery.
- Proper Ventilation: Ensure adequate ventilation around the inverter to prevent overheating.
- Grounding: The inverter must be properly grounded.
- Overload Protection: Do not exceed the inverter's rated output power.
- Reverse Polarity: Ensure correct DC input polarity. Reverse polarity connection will damage the inverter.

4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your PROsine Inverter. Consult a qualified electrician or installer if you are unsure about any steps.
4.1 Unpacking and Inspection
Carefully unpack the inverter and inspect it for any shipping damage. Report any damage to your dealer immediately.
4.2 Mounting Location
Choose a mounting location that is:
- Dry and protected from moisture.
- Well-ventilated to dissipate heat.
- Accessible for wiring and maintenance.
- Close to the battery bank to minimize DC cable length.
- Away from flammable materials or gases.
The inverter can be mounted horizontally or vertically. Ensure the mounting surface is sturdy enough to support the inverter's weight (approximately 12 pounds).
4.3 DC Wiring (Battery Connection)
Connect the inverter directly to your 12V DC battery bank. Use appropriately sized, high-quality DC cables to minimize voltage drop and ensure efficient power transfer. The unique 180-degree DC terminals facilitate flexible cable routing.
- Connect the positive (+) terminal of the inverter to the positive (+) terminal of the battery bank.
- Connect the negative (-) terminal of the inverter to the negative (-) terminal of the battery bank.
- Install appropriate DC overcurrent protection (e.g., a fuse or circuit breaker) as close to the battery as possible.
4.4 AC Wiring (Output Connection)
The inverter provides 120Vac, 60Hz, 1800W AC output. Connect your AC loads to the standard duplex outlet on the inverter. For permanent installations, consult local electrical codes.

Figure 1: Front view of the Xantrex PROsine 1800 Power Inverter. The image displays the yellow and silver casing, with the front panel featuring an LCD screen, control buttons, and two standard 120Vac, 60Hz, 1800W outlets. The Xantrex logo is visible on the top and front panel.
4.5 Remote Display Installation (Optional)
The LCD display can be removed from the unit and mounted remotely for convenient monitoring and control. Refer to the detailed instructions in the full manual for remote mounting procedures.
5. Operating Instructions
Once properly installed, operating the PROsine Inverter is straightforward.
5.1 Powering On/Off
- To turn the inverter ON, press and hold the power button on the front panel until the LCD display illuminates.
- To turn the inverter OFF, press and hold the power button again until the display turns off.
5.2 LCD Display and Monitoring
The backlit LCD graphical output display provides real-time information about the inverter's operation, including:
- DC input voltage (VOLTS)
- AC output power (WATTS)
- Battery charge status (if applicable)
- Error codes or warnings
Use the navigation buttons next to the display to cycle through different information screens.
5.3 Powersave Mode
The inverter features a Powersave mode that automatically reduces power consumption to only 1.5 watts when no AC load is detected. This feature helps conserve battery energy. The inverter will automatically "wake up" and provide full power when an AC load is connected.
5.4 Connecting AC Loads
Plug your AC appliances directly into the inverter's AC outlets. Ensure that the total continuous power draw of your appliances does not exceed the inverter's 1800 watt continuous rating. The inverter can handle surge loads up to 2900 watts for brief periods, typically for motor starting.
6. Maintenance
The Xantrex PROsine Inverter requires minimal maintenance to ensure long-term reliable operation.
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners or solvents. Ensure ventilation openings are free from dust and debris.
- Connections: Regularly check all DC and AC connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and poor performance.
- Battery Maintenance: Follow the battery manufacturer's recommendations for battery maintenance, including checking electrolyte levels (for flooded batteries) and terminal cleanliness.
- Ventilation: Ensure that the area around the inverter remains clear and well-ventilated to prevent heat buildup.
7. Troubleshooting
The PROsine Inverter is designed with built-in protection features. If the inverter shuts down or displays an error, refer to the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not turn on. | No DC input power; Low battery voltage; Blown DC fuse/breaker; Loose connections. | Check battery connections and voltage; Recharge or replace batteries; Check and replace fuse/reset breaker; Tighten all connections. |
| No AC output. | Overload; Short circuit on AC output; Over temperature; Inverter in Powersave mode. | Reduce AC load; Check AC wiring for shorts; Ensure adequate ventilation; Connect a small AC load to wake up inverter from Powersave. |
| Overload shutdown. | Connected load exceeds inverter's continuous or surge rating. | Reduce the total AC load. Disconnect some appliances and restart the inverter. |
| Over temperature shutdown. | Insufficient ventilation; High ambient temperature; Blocked cooling vents. | Improve ventilation around the inverter; Ensure cooling vents are clear; Allow inverter to cool down before restarting. |
| Reverse polarity protection activated. | DC input cables connected incorrectly (+ to -). | Immediately disconnect DC power. Correct the positive and negative connections. |
| AC backfeed protection activated. | AC power from an external source (e.g., utility, generator) is connected to the inverter's output. | Ensure no external AC source is connected to the inverter's output. The inverter is designed to produce AC, not accept it. |
If the problem persists after attempting these solutions, contact Xantrex customer support or a qualified service technician.
