If the power consumed by a device is less than the threshold of the Search mode
circuitry, and Search mode is enabled, the inverter will not run. Most likely the
solution will be to disable the Search mode feature or lower the sense threshold.
Refer to Xantrex Tech Note TN 003 ("Making Sense of Search Mode") for more
information.
Some devices cannot be detected when scanned by Search mode circuitry. Small
fluorescent lights are the most common example. Some computers and
sophisticated electronics have power supplies that do not present a load until line
voltage is available. When this occurs, each unit waits for the other to begin. To
drive these loads, either a small companion load like a light bulb rated for more
than the Search Watts setting must be used to bring the inverter out of Search
mode, or the inverter may be programmed to remain on by disabling the Search
feature. (See "Using Search Mode" on page 3–8.)
You may notice that your clocks may not be accurate. Some of the clocks on your
appliances may reset when the inverter/charger is in Search mode.
When the inverter is in Search mode, it may fail to start some loads even though
the rated wattage on the load is more than the Search Watts setting. Apply an
additional load (companion load) to make the inverter exit Search mode.
