This setting controls when the inverter turns off due to a low battery voltage condition. The inverter will turn
off only after this level has been reached for the period of time set by the following item. When the
automatic generator control system is used, the generator will be started when the battery voltage has
dropped below this value for 30 seconds continuously. This will occur even during the quiet time period.
This setting is not temperature compensated.
Set LBCO delay
minutes

All models
Range: 00 to 255
This setting controls how long the inverter delays before turning off due to a low battery voltage condition.
The inverter will turn off only after the LOW BATTERY CUT OUT VDC level has been reached for this
period of time continuously. If you are using the automatic generator control system, don’t set this delay
period shorter than the amount of time it takes the generator to start and connect or the power will go off
and then back on when the generator auto starts due to a LBCO condition.

This setting controls when the inverter turns back on once it has shut off after the battery reached the
LOW BATTERY CUT OUT VDC setting. It is also used to control when the system resumes powering the
AC loads from the inverter when LBX mode is being used. In LBX mode, the best performance will often
be achieved if this setting is higher than the BULK and FLOAT VOLTS DC setting in order to reduce
cycling of the system. The DC charging sources (wind, solar etc.) must then cause the battery voltage to
rise above the charger settings before the system resumes inverter mode operation. This setting is not
temperature compensated.

This is the battery voltage at which the inverter turns off. The inverter will automatically restart once the
battery voltage has dropped 1.5 VDC below the HBCO setting for 12 VDC systems, 3 VDC for 24 VDC
systems, and 6 VDC for 48 VDC systems. This setting is not temperature compensated.
Set search
watts
48
All models
Range: 00 to 240
The sensitivity threshold of the search mode circuit is adjustable. If set to zero, it is effectively disabled.
The sensitivity is only adjustable in increments of 16 watts.
Set search
spacing
59
All Models
Range: 10 to 255*
The length of time between each search pulse is also adjustable. The setting is in cycles. Therefore, a
setting of 60 would generate search pulses that are 1 second apart. The range of settings is from 10 to
255 cycles, which equals a search pulse from 6 times a second to once every 4.25 seconds. This
adjustment can be used to speed up the response of the search circuit, which will reduce the delay when
starting a load. Reducing the spacing increases the power consumption of the inverter when it is in the
search mode, reducing the benefit of it. Typically, the default value is acceptable.
