Product Review (November 2009)
By Kevin Nakano
Xantrex is a company that specializes in power inverters offering small portable units as well as full high-power, true sine wave (TSW) systems for residential and commercial applications. The company also carries a line of high power mobile products for marine and RV use. The Xantrex PROwatt SW Series True Sine-Wave AC power inverters fall into this category and are available in 600, 1000 and 2000 watts versions. These inverters are designed with high surge capability, capable of providing the necessary current to start up demanding electrical loads. We received the PROwatt SW 2000 Inverter capable of supplying an amazing 2000 watts of true sinewave power (120V at 16.6 amps max). True sinewave inverters are more complicated than the cheaper modified sinewave designs and cost significantly more to produce. Since many products have issues when running from a modified sinewave inverters, the pure sinewave designs are more desirable in some applications.
The PROwatt SW 2000 is a compact unit measuring only 3.9" x 11.8" x 13.7" (H x W x D), making it ideal for use in work trucks, recreational vehicles, marine vessels and other commercial vehicles. The unit weighs a modest 11 pounds. Power and Fault indicators give the user feedback in the event the inverter encounters a problem with line voltage, overloading, or overheating. The low-voltage alarm occurs when the battery drops to 11.0 volts and shuts down at 10.5VDC to prevent over-draining of the battery. Over-voltage detection and sutdown occurs at 15.5VDC. The dual GFCI AC outlets can provide up to 120VAC at a maximum of 16.6 amp. There is also a power jack on the front for USB chargeable devices that provide 5V at 500mA. When the inverter is used with a remote control, the PROwatt SW Series has the ability to provide automatic vehicle ignition lockout using the RJ45 jack. This shuts down the inverter's output when the vehicle's ignition is not switched on to prevent accidental battery drain.
The inverter is designed to operate at temperatures ranging from 32°F − 104°F (0°C − 40°C). We installed the unit into our Nissan Armada truck for test purposes. Once the inverter is connected to the battery, the user must press and hold the power button down to turn the inverter on or off. We tested the inverter with a standard 300-watt halogen lamp, which is a simple load with no current transients. The input voltage to the inverter displayed 12.5 volts and 0.28 kilowatts (280 watts) as the load. The display toggles between the two readings every few seconds. The output voltage remained at 120 volts regardless of the load we presented on the inverter. This inverter has a solid design and appears to be load independent.
