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.
