SEARCH MODE WATTS Potentiometer
The Search Mode Watts potentiometer adjusts the current threshold required to bring the
inverter out of search mode into full wave operation. With search mode enabled, the inverter
pulses the AC output looking for an applied load. With no load detected, the inverter goes into the
search mode to minimize energy consumption. When a load is applied, the load current is
sensed, bringing the inverter into full power operation. Disabling the threshold (setting the
potentiometer fully CCW) causes the inverter to remain ON (in full power operation) regardless of
an applied load.
To set the Search Mode Watts:
• Remove the AC input source from the inverter. The inverter switches to battery operation.
Ensure all inverter supported appliances are switched OFF.
• Turn the potentiometer completely CW (to MAX).
• Switch on the load which will trigger the inverter to full power. This could be a lamp located in
a convenient location if the power goes out. The light may flicker as the inverter searches the
line for a load. The green INVERTER MODE LED blinks 2-3 times a second, indicating the
inverter is in the SEARCH MODE.
• Slowly turn the potentiometer CCW (toward MIN) when the proper setting is found, the lamp
and INVERTER MODE LED will light steady.
• Turn the lamp OFF for a moment, the inverter should switch back to the SEARCH MODE.
Turn the lamp ON, ensure the inverter comes out of the Search Mode. Adjust the
potentiometer up or down as necessary.
NOTE: The Search Mode only activates when the unit is operating in the inverter mode (from
batteries) to prevent unnecessary battery discharge when electrical power is not required. If the
inverter is supporting loads that must constantly be powered, turn the search mode OFF by setting
the potentiometer fully CCW to the DEFEAT position.
NOTE: Some loads constantly draw power even though they are switched OFF. These include: TVs
with instant-ON circuits, microwaves with digital displays, VCRs, etc. It is best to operate these
devices from another circuit or install a switch to turn these OFF completely.
NOTE: When the SEARCH MODE is used with series stacked inverters, only 120 VAC loads
connected to the “master” inverter will bring the unit out of the search mode. Refer to Series
Stacking in the Installation section of this manual.
