3–8
bring the battery level back above the Low Batt Cut Out setting. After shutdown,
the inverter does not support any AC loads, and AC loads must be powered by
either a generator or grid power.
If using an automatic generator starting system, it is recommended to set the AGS
voltage trigger setting higher than the XW Inverter/Charger Low Batt Cut Out
voltage. Otherwise, inverter output turns off and then back on when the generator
auto-starts.
If using an automatic generator starting system with the start trigger set to the
same voltage as the LBCO voltage, do not set the LBCO Delay for less than the
amount of time it takes the generator to start and connect. Otherwise, inverter
output turns off and then back on when the generator auto-starts.
While idling in Search mode, the inverter sends out an electrical search pulse that
travels through the AC wiring "looking" for connected loads. The frequency of
the search pulse is set using the Search Delay setting.
After a load larger than the Search Watts setting is detected, the inverter turns on.
Search mode allows you to selectively power only items that draw more than a
certain amount of power, which can result in power savings.
The XW Inverter/Charger has a no-load power draw of about 28 watts. Enabling
Search mode reduces this power draw to less than 8 watts.
The Search mode feature on the inverter is only valuable if the inverter can spend
a fair amount of time "sleeping" each day. Therefore, if Search mode is to be
utilized it must be adjusted properly. The initial adjustment should be made so that
the inverter comes on only when needed.
Certain types of loads can cause Search mode not to work as expected. These
types of loads are described on page 4–3 of the Troubleshooting chapter. If these
kinds of loads are in the system, follow the suggestions given to eliminate the
problem. Some televisions with instant-on circuits have a menu or control to
disable it. If clocks are the problem load, consider using battery-powered units.
If the problem loads cannot be eliminated, there are two work-around solutions:
1. Disable Search Mode from the main XW Inverter/Charger Setup menu,
causing the inverter to always remain at full output voltage.
2. Use a search-friendly "companion load" whose only purpose is to be switched
on to "wake up" the inverter to power the load that is unable to bring the
inverter out of Search mode.
Important:
Search mode does not function in installations with multiple XW Inverter/
Chargers. The combined current draw of multiple inverter/chargers falsely brings the units
out of Search mode. Search Mode should be disabled on the Setup menu of each XW
Inverter/Charger.
