3.2.2 Search Watts Menu
• SEARCH
– This selection allows you to turn off the Search Watts feature,
or to adjust the power level to determine when the feature becomes
active. If this feature is not needed, select
SEARCH = Off
. When the
Search Watts feature is turned off, the inverter continuously provides
full AC voltage to the loads.
Default setting:
SEARCH = 5 Watts
Range: Off, 5 Watts, 20 Watts
Info:
When the Search Watts feature is active “
Search
” appears
on the bottom line of the LCD display, and the green INV LED will
slowly
fl
ash.
What is the Search Watts feature?
This feature is used to help save bat-
tery power by reducing the inverter’s output to search pulses when there
is no detectable load. If someone turns on a load greater than the wattage
level setting while the inverter is searching, the inverter will start inverting
to provide full voltage on its output.
Should I use the Search Watts feature?
If the inverter can spend a great
deal of time searching (to reduce the power drain on your batteries) and you
can tolerate small loads (less than 5 watts) from being on, then the Search
Watts feature should be used. However, if you require some small loads (e.g.,
digital clocks, satellite receivers, answering machines, etc.,) to always be on,
then this feature should be turned off (
SEARCH = Off
).
Where to set:
The
SEARCH Watts
setting should be adjusted to the same
power level (or the next lower setting) of the smallest load that you want to
run. If you don’t know the wattage of the smallest load you want to run, turn
the switch for the load on and then decrease the
SEARCH Watts
setting until
the load comes on and stays on.
Example:
You have reviewed all the loads you want to run and deter-
mined that the smallest load is a 20 watt light. Set
SEARCH = 20 Watt
.
Whenever you turn on any load (because all the loads are greater than
20 watts), the inverter will stop searching and start inverting to deliver
power to the load.
Info:
Even though the Search Watts feature is on, some connected
equipment may draw enough current even while off to keep the
inverter in Invert mode.
