5 Operation
Operating statuses
This section describes normal operation as well as problems that could occur when you use the inverter. If you have a problem, see “Troubleshooting” on page 24.
The XPower Inverter 450 is capable of continuously powering most
120 V AC products that use 360 W or less. Its AC output waveform, called “modified sine wave,” is designed to function similarly to the sine wave shape of utility power.
The power, or “wattage,” rating of AC products is the average power they use. When most AC products are first switched on, they initially consume more power than their power rating. TVs, monitors, and electric motors are examples of products that have high “surge” requirements at start up. Although the XPower 450 can supply momentary surge power as high as 700 W, occasionally some products rated less than 360 W may exceed its surge capabilities and trigger its safety overload shutdown feature. If this problem occurs when attempting to operate several AC products at the same time, first try switching on the inverter with all AC products switched off, then one by one switch each on, starting with the high surge product first.
