Xantrex PROWatt SW 2000 Inverter Review | SolarKnowHow

Xantrex 2000W Power Inverter

The Xantrex PROWatt SW 2000 pure sine wave inverter is an easy-to-use, easy-to-install power inverter that provides you with an economical way of handling all of your power needs.

Its pure sine-wave output provides clean power for all types of electrical conveniences, including power tools, advanced electrical appliances, and power-demanding home appliances. Its portable design makes it a perfect choice for commercial trucks, RVs, and marine applications.

Why a Pure Sine Wave Inverter?

To best suit your power needs, the pure sine wave inverter is more efficient than the modified sine wave inverter. This is because they produce clean power like utility-supplied electricity, which helps to run your power-demanding appliances quieter, faster, and cooler than the modified sine wave inverter.

They are better at running more appliances efficiently without wasting energy. All your devices, including printers, microwaves, and any other power-demanding appliance, will work properly with this inverter and do not risk getting damaged or failing unexpectedly, as seen in the modified sine wave inverter.

However, the pure sine wave inverter is more expensive than the modified sine wave power inverter. This inverter is a 2000 Watt inverter but an 1800 Watt Pure Sine Wave Inverter.

Xantrex PROWatt SW 2000 Features

Xantrex 1000W Pure Sine Inverter

Power Rating

Similarly rated inverters state that they have a continuous power rating of 2000W and a peak surge capacity [output power to kick-start appliances that require a large amount of power on startup power] of 4000W. However, the information provided by these inverter companies is somewhat misleading because an inverter rated 2000W does not mean that you can run a 2000W continuous output load on the inverter or run appliances that require a startup power of 4000W.

Xantrex is the only company I am aware of that is honest enough to state otherwise. Their ProWatt inverter has a continuous output of 1800W and a peak surge capacity of 3000W.

This sounds very realistic to me and is one of the reasons I’d go for this inverter.

It is important for you to check the maximum rating of your devices before purchasing this inverter. Do not purchase this inverter if your device’s power rating exceeds this inverter’s power rating.

120VAC Dual GCFI AC Outlets

Unlike similar rated pure sine wave inverters, this outlet is equipped with a standard Ground Fault Circuit Interrupter (GFCI) device for safe operation. This feature provides a safe and convenient connection that allows you to safely power your electrical home appliances directly from these outlets.

They protect you from electric shock and accidental fire outbreaks, especially when you use the inverter in wet locations. It is important to note that these outlets are rated 16.6 amps maximum, i.e., 8.3 amps for each outlet.

Built-in USB Port

This 5V USB port allows you to conveniently power your cell phones and other modern USB-enabled devices. Most inverters feature this USB, but while some are dual, this inverter has just one 5VDC, 500mA USB port.

Built-In Digital Display

The display provides useful information that helps you monitor the status of the inverter while in operation. You will know when the battery needs recharging, its input voltage, output power, and error code information. This feature is a huge benefit of purchasing this inverter as most similarly rated inverters do not have this visual feature.

LED Indicators 

These indicators also work with the LCD to give you a status update on your inverter. A green LED indicates that the unit is on and receiving power.  The green LED remains on whenever a shutdown occurs due to an error.  A red LED indicates an error or alarm condition.

Remote Switch Port 

This inverter has an option for a PROwatt remote panel purchased separately. This port allows connection directly to the remote panel accessory, which gives you access to control the inverter from about 25ft. You can turn it off and on without even having to move an inch. However, this port is not wireless, so you will need to connect the optional remote panel using a communications cable.

Heavy-duty Terminals 

This feature lets you connect your batteries easily and accommodates large electrical loads. It has large positive and negative terminal lugs to supply the high current needed for this power inverter. A separate ground lug is also provided for the safe delivery of power.

Thermostatically Controlled Cooling Fan 

The two small internal fans keep the unit cool while operating under heavy loads, so proper ventilation is required for reliable operation. Like the similarly rated inverters, they are thermostatically controlled, meaning they only come on when the temperature rises above the normal temperature range for this inverter. The fans are ultra-quiet and will not be any disturbance to you, unlike the modified sine wave inverters.

 Xantrex PROWatt SW 2000 Accessories

Xantrex PROWatt SW 2000 remote starter.

PROwatt Remote Panel with Ignition Lockout: This panel allows you to easily control and monitor the inverter from inside your motorhome. The automatic ignition lockout allows you to remotely shut down the inverter when the vehicle is not running to prevent unnecessary battery drain.  However, the connection process is not wireless. A 25ft communication cable must be purchased with this panel.

Inline Transfer Relay: This plugs into the front of the inverter and allows you to pull one circuit from the breaker box to supply power to an appliance from the inverter.

Protective Features

Low Standby Battery Demand ensures that you do not have to worry about the excessive drain on your battery if you leave the inverter on for a few days. When the inverter is on but no power is supplied to a load, the inverter draws less than 800 mA from the battery.

Low Voltage Shutdown: This automatically shuts the inverter down if the battery voltage drops below 10.5VDC, thus protecting the battery from being completely discharged. The unit recovers automatically within five minutes after shutdown once the battery voltage reaches above 11.5VDC. After five minutes, the unit turns itself off.

Low Voltage Alarm: This feature alerts you whenever the battery voltage level has become discharged to 11V or lower. It allows you to disconnect your devices before the inverter shuts down completely.

Over Voltage Shutdown: This feature shuts the inverter down automatically if the input voltage rises to more than 15.5VDC to prevent devices from getting damaged. The unit recovers automatically within five minutes after shutdown once the battery voltage falls below 15.5VDC. After five minutes, the unit turns itself off.

AC Overload Shutdown: This feature prevents overheating and possible damage by shutting the unit down automatically if a short circuit occurs or the loads attached to the inverter exceed the operating limits.

Over Temperature Shutdown: This feature turns the inverter off if its temperature rises above an acceptable level. Within five minutes after shutdown, the unit recovers automatically once the temperature of the unit cools down. After five minutes of operating at a high temperature, the unit turns automatically.

Ground Fault Circuit Interrupter (GFCI) Protection: This protects you from electric shock by cutting off electricity in the AC circuits when it senses a change in direction in the current flow.


This inverter comes with a full two-year warranty.
