The LCD will display a battery low voltage message when the battery capacity is near
depletion. The End of Battery Discharge announcement is displayed when the battery
end voltage is reached. At this time, the inverter will perform an electronic shutdown to
prevent battery loss of life typical from extreme deep discharge conditions. When the
input power is restored, the inverter will automatically restart to power the load, and
the batteries will be simultaneously recharged. The End of Battery announcement is
shown at the bottom of the screen.
