Review (August 2009) - Xantrex
By Kevin Nakano
Xantrex offers a full line of power inverters ranging from small portable units to full high-power, true sine wave (TSW) inverter/charger systems that can be installed in both residential and commercial applications. If there is one thing that Xantrex knows, it is inverters. Xantrex has licensed the Duracell name to use on a series of consumer products. One such products is the new Duracell® Digital Inverter series available in three models (200, 400 & 800 Watt) each providing a pair of three-prong grounded AC outlets. These inverters are designed to power electronics while on the go and features an interactive LED display that provides the user with the input and output voltages, and power output. We received the Digital Inverter 800 for review and connected it to the battery on our Nissan Armada. The digital inverter converts 12-volt DC power from a vehicle battery into a 120-volt AC using a Modified Sine Wave (MSW). The MSW has the same RMS (Root Mean Square) as a True Sine Wave (TSW) inverter, but costs substantially less to manufacture. Since some devices may have problems due to the waveform of the MSW, users should check to make sure their product can properly operate with MSW inverters.
The Duracell Digital Inverter 800 also includes a built-in fan in case the power electronics gets hotter than normal. For lower power loads the fan may not even run, but when the load increases and power dissipation goes up the unit will keep cool. Should the battery voltage get too low, an audible alarm will sound. In the event of a failure, the unit will display a fault code to make troubleshooting easier. The display can be difficult to read in direct sunlight.
