Menu Item Descriptions

The sensitivity control should be adjusted so that the smallest load being
run can "wake" the inverter up and cause it to deliver power to the load.
If loads change significantly, then re-tuning of the search sensitivity will
be required. It may take several adjustments to tweak the sensitivity to
just the right point.
Certain types of loads can cause Search Mode to not work as expected.
These types of loads are described on page 9–3 of the Troubleshooting
Section. 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 just can't be eliminated in one of the suggested
manners, there are two work-around solutions:
1. disable the search sense feature, causing the inverter to always remain
at full output voltage, or
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.
Guidelines for setting this menu item:
Setting this mode to 00 disables this function. Default is 08 watts.
When the inverter is searching the output for loads, lights that have a
wattage lower than this setting, may flash momentarily.
Battery Charger Functions
When AC power is available, the inverter can operate as a battery charger.
Different batteries will require different charging voltage levels. Not
charging batteries at the required levels can shorten battery life or
possible damage them. It will be necessary to select the voltage levels
required and to set the voltage limits for the various stages of charging.
Battery charging parameters are set in 12 Battery Charging Menu.
Note: Search Mode, by function cannot work with timers or devices that need
power 24 hours a day.
Examples of devices with timers include coffee makers with brew timers,
refrigerators, and freezers with defrost timers.
Examples of devices that need power 24 hours a day include telephone
answering machines, alarm systems, motion detection lights, and some
thermostats.
