976-0043-01-02 6–13
This voltage level is used to indicate that the batteries have a sufficient
level of charge for the inverter to start using power from the battery bank.
11C Low Battery Cut Out VDC
When the batteries discharge to the level set in 11C Low Battery Cut
Out VDC, and are held at or below this level for the 11D LBCO Delay
time, the inverter output shuts down and transfers any available AC
source (generator or grid) to the charger to bring the battery level back up
to the 11B Low Battery Cut In Vdc level. The inverter will not support
any AC loads when in this condition. AC loads will have to be powered
by either a generator or grid power. This is the lowest voltage level
acceptable for battery use by the inverter.
11D LBCO Delay Minutes
Menu item 11D LBCO Delay Minutes is used to set the length of time
(in minutes) that the inverter is allowed to continuously operate at or
below the LBCO level set in menu item 11C Low Battery Cut Out
before it shuts off.
Once the inverter has shut off, the battery voltage must rise above the
value (set in menu 11B Low Battery Cut In) for inverter operation to
resume.
Guidelines for setting this menu item:
• If using an automatic generator starting system, do not set this delay
period shorter than the amount of time it takes the generator to start
and connect. Otherwise, the power will go OFF and then back ON
when the generator auto-starts due to the LBCO condition.
