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
loss of battery life, which is 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 Discharge announcement
is shown at the bottom of the screen.
